XmContainer(3)XmContainer(3)NAMEXmContainer — The Container widget class
SYNOPSIS
#include <Xm/Container.h>
DESCRIPTION
Container manages child widgets that have the ContainerItem trait.
These child widgets can be viewed in several different layout formats,
selected using different selection types and techniques, and directly
manipulated by the user.
Three different formats or views are supported by the Container. They
are specified via the XmNentryViewType resource:
· XmLARGE_ICON
· XmSMALL_ICON
· XmANY_ICON
Three different layout types are supported by the Container. They are
specified by the XmNlayoutType resource:
· XmSPATIAL
· XmOUTLINE
· XmDETAIL
In the XmSPATIAL layout type, several other resources (XmNspatialStyle,
XmNspatialIncludeModel, XmNspatialSnapModel) control the positioning of
the items within the Container; an application programmer can specify
these resources so that the Container strictly enforces the position of
each item or so that the Container positions items according to con‐
straint resources specified for each item. The user, however, can
alter the position of an item in the XmSPATIAL layout type within the
Container by direct manipulation; for example, by pressing BTransfer
over the item and then dragging and releasing BTransfer over some loca‐
tion within the Container.
In the XmOUTLINE layout type, the Container controls the positioning of
the items. Items within the Container can have parent-child relation‐
ships between them. Each item's XmNentryParent resource can specify
another item in the same Container as its parent; items with a non-NULL
value for XmNentryParent can only be displayed in the XmOUTLINE layout
type. In the XmOUTLINE layout type, items are positioned in a tree con‐
figuration with connecting lines drawn to illustrate the relationships.
Items are positioned top to bottom in the order specified by XmNposi‐
tionIndex within their parent. Container positions a PushButton next
to each item that has a parent relationship to other items. The Push‐
Button contains a pixmap to illustrate whether the child items are
shown or not; the user can activate the PushButton to toggle between
showing or hiding the child items. Direct manipulation to alter the
position of the item is not supported in the XmOUTLINE layout type.
Note that the XmNtraversalOn resource of the PushButtons created by
Container are set to False.
The XmDETAIL layout type is the same as XmOUTLINE, except that each
item can also display additional information as rows in columns with
column headers specified in the XmNdetailColumnHeading resources. In
each item row, the item's detail information (see the reference page on
XmIconGadget for a description of the XmNentryDetail resource) is dis‐
played. Items are positioned top to bottom in the order specified by
XmNpositionIndex within the parent.
Selection
When a child widget of the container is selected, the container speci‐
fies that the item should display the appropriate visual information to
the user via the ContainerItem trait. The application program is noti‐
fied of selection changes through XmNselectionCallback.
The container uses four selection policies:
· Single
· Browse
· Multiple
· Extended
In Single Select and Browse Select modes, only one item can be selected
at a time. Pressing BSelect on an item selects it and deselects any
other selected item. Pressing BSelect over an empty space in the Con‐
tainer deselects all items. In Browse Select, dragging BSelect moves
the selection as the pointer is moved.
In Multiple Select and Extended Select modes, any number of items can
be selected at the same time. In Multiple Select, pressing and drag‐
ging BSelect or BExtend to specify an item, range of items, or group of
discontiguous items causes the selection states of those items to be
toggled. In Extended Select, pressing and dragging BSelect to indicate
an item, range of items, or group of discontiguous items selects those
items and deselects all others. Pressing and dragging BExtend in
Extended Select to indicate an item, range of items, or discontiguous
group of items causes the selection states of those items to be tog‐
gled.
Several techniques are available to indicate an item, range of items,
or group of discontiguous items in the Multiple Select and Extended
Select modes.
In the XmSPATIAL and XmOUTLINE layout types, the XmNselectionTechnique
resource specifies the techniques to be used to indicate items. The
default specification of XmTOUCH_OVER allows both the Random-Swipe and
Marquee techniques to be used when XmNlayoutStyle is XmSPATIAL. The
default specification of XmTOUCH_OVER allows the Range-Swipe, Range-
Click, and Marquee techniques to be used when XmNlayoutStyle is XmOUT‐
LINE.
Discontiguous groups of items can be selected using the Random-Swipe
technique. In the Random-Swipe technique, pressing BSelect (or BEx‐
tend) over an item and dragging BSelect over other items selects all of
those items. Only those items that pointer passed over are selected.
In the Range-Swipe technique, the user presses BSelect (or BExtend)
over the first item and releases BSelect over the last item; all items
within the range between the first and last item are selected whether
the pointer actually passed over them or not. In the Range-Click tech‐
nique, the user presses and releases BSelect (or BExtend) over the
first item and then presses and releases BExtend over the last item.
In the Marquee technique, pressing BSelect (or BExtend) over a blank
space within the Container indicates the starting point of a Marquee
rectangle. Dragging BSelect draws a Marquee rectangle (rubberband line)
between the starting point and current pointer. All items completely
within the Marquee rectangle are selected.
Specifying XmTOUCH_ONLY for XmNselectionTechnique enforces the Random-
Swipe technique even when BSelect (or BExtend) is pressed over a blank
space. Similarly, specifying XmMARQUEE enforces the Marquee technique
even when BSelect (or BExtend) is pressed over an item; since the item
over which the press occurs is only partially included in the Marquee
rectangle, it is not selected. XmMARQUEE_EXTEND_START and XmMAR‐
QUEE_EXTEND_BOTH enforce the Marquee technique and also cause the rec‐
tangle to extend automatically around the first item indicated and, for
XmMARQUEE_EXTEND_BOTH, the last item.
In the XmDETAIL layout type, the Range-Swipe and Range-Click techniques
are available to indicate a range of items for selection.
Container uses the XmQTcontainerItem, XmQTscrollFrame, and XmQTspeci‐
fyRenderTable traits and holds the XmQTcontainer and XmQTtransfer
traits.
Data Transfer Behavior
Container supports dragging of selected items from the widget. Depend‐
ing on the value of XmNprimaryOwnership, Container can also support
primary selection.
As a source of data, Container supports the following targets and asso‐
ciated conversions of data to these targets:
locale If the locale target matches the widget's locale, the widget
transfers the selected items in the encoding of the locale.
The value for each item transferred, except the last,
includes a trailing separator. Each item value is the XmNla‐
belString of the item.
COMPOUND_TEXT
The widget transfers the selected items as type COM‐
POUND_TEXT. The value for each item transferred, except the
last, includes a trailing separator. Each item value is the
XmNlabelString of the item.
DELETE The widget deletes the selected items.
PIXMAP The widget transfers a list of the pixmap IDs of the selected
items as type DRAWABLE.
STRING The widget transfers the selected items as type STRING. The
value for each item transferred, except the last, includes a
trailing separator. Each item value is the XmNlabelString of
the item.
TEXT If the selected items are fully convertible to the encoding
of the locale, the widget transfers the selected items in the
encoding of the locale. Otherwise, the widget transfers the
selected items as type COMPOUND_TEXT. The value for each
item transferred, except the last, includes a trailing sepa‐
rator. Each item value is the XmNlabelString of the item.
_MOTIF_CLIPBOARD_TARGETS
The widget transfers, as type ATOM, a list of the targets it
supports for immediate transfer for the CLIPBOARD selection.
These include _MOTIF_COMPOUND_STRING and PIXMAP. If the
selected items are fully convertible to STRING, these also
include STRING; otherwise, they also include COMPOUND_TEXT
and UTF8_STRING.
_MOTIF_COMPOUND_STRING
The widget transfers the selected items as a compound string
in Byte Stream format. The value for each item transferred,
except the last, includes a trailing separator. Each item
value is the XmNlabelString of the item.
UTF8_STRING
The widget transfers the selected items as type UTF8_STRING.
The value for each item transferred, except the last,
includes a trailing separator. Each item value is the XmNla‐
belString of the item.
_MOTIF_DEFERRED_CLIPBOARD_TARGETS
The widget transfers, as type ATOM, a list of the targets it
supports for delayed transfer for the CLIPBOARD selection.
This widget currently supplies no targets for
_MOTIF_DEFERRED_CLIPBOARD_TARGETS.
_MOTIF_DRAG_OFFSET
The widget transfers a list of two 16-bit numbers, of type
INTEGER, representing an x and y offset for an item being
dragged. This offset is calculated so that, if the offset
were added to the x and y coordinates at the drop site, and
the dragged pixmap placed at that position, it would corre‐
spond to the position the user would expect the pixmap to
placed at, based on the drag icon used at the drop site.
_MOTIF_EXPORT_TARGETS
The widget transfers, as type ATOM, a list of the targets to
be used as the value of the DragContext's XmNexportTargets in
a drag-and-drop transfer. These include _MOTIF_COM‐
POUND_STRING, PIXMAP, COMPOUND_TEXT, the encoding of the
locale, STRING, TEXT, BACKGROUND, FOREGROUND, and
UTF8_STRING.
As a source of data, Container also supports the following standard
Motif targets:
BACKGROUND
The widget transfers XmNbackground as type PIXEL.
CLASS The widget finds the first shell in the widget hierarchy that
has a WM_CLASS property and transfers the contents as text in
the current locale.
CLIENT_WINDOW
The widget finds the first shell in the widget hierarchy and
transfers its window as type WINDOW.
COLORMAP The widget transfers XmNcolormap as type COLORMAP.
FOREGROUND
The widget transfers XmNforeground as type PIXEL.
NAME The widget finds the first shell in the widget hierarchy that
has a WM_NAME property and transfers the contents as text in
the current locale.
TARGETS The widget transfers, as type ATOM, a list of the targets it
supports. These include the standard targets in this list.
These also include _MOTIF_COMPOUND_STRING, PIXMAP, COM‐
POUND_TEXT, the encoding of the locale, STRING, TEXT, and
UTF8_STRING.
TIMESTAMP The widget transfers the timestamp used to acquire the selec‐
tion as type INTEGER.
_MOTIF_RENDER_TABLE
The widget transfers XmNrenderTable if it exists, or else the
default text render table, as type STRING.
_MOTIF_ENCODING_REGISTRY
The widget transfers its encoding registry as type STRING.
The value is a list of NULL separated items in the form of
tag encoding pairs. This target symbolizes the transfer tar‐
get for the Motif Segment Encoding Registry. Widgets and
applications can use this Registry to register text encoding
formats for specified render table tags. Applications access
this Registry by calling XmRegisterSegmentEncoding and
XmMapSegmentEncoding.
As a destination for data, Container supports only the dropping of
items being dragged from the same widget. Subclasses and the XmNdesti‐
nationCallback procedures are responsible for any other data transfers
to the widget.
Classes
Container inherits behavior, resources, and traits from the Core, Com‐
posite, Constraint, and XmManager classes.
The class pointer is xmContainerWidgetClass.
The class name is XmContainer.
New Resources
The following table defines a set of widget resources used by the pro‐
grammer to specify data. The programmer can also set the resource val‐
ues for the inherited classes to set attributes for this widget. To
reference a resource by name or by class in a .Xdefaults file, remove
the XmN or XmC prefix and use the remaining letters. To specify one of
the defined values for a resource in a .Xdefaults file, remove the Xm
prefix and use the remaining letters (in either lowercase or uppercase,
but include any underscores between words). The codes in the access
column indicate whether the given resource can be set at creation time
(C), set by using XtSetValues (S), retrieved by using XtGetValues (G),
or is not applicable (N/A).

XmNautomaticSelection
Indicates whether the Container invokes selection callbacks
when each item is selected (or toggled) or whether selection
callbacks are not invoked until the user has completed selec‐
tion actions (for example, the user has released the mouse
button). It can have one of the following values:
XmAUTO_SELECT
Makes selection callbacks automatically when each
item is selected or toggled. This may also be the
value TRUE.
XmNO_AUTO_SELECT
Delays selection callbacks until the user has fin‐
ished selection actions. This may also be the value
FALSE.
XmNcollapsedStatePixmap
Specifies the pixmap to display on a PushButton next to a
Container item with child items, when XmNoutlineButtonPolicy
is XmOUTLINE_BUTTON_PRESENT. XmNcollapsedStatePixmap indi‐
cates that the child items are not displayed. If set to
XmUNSPECIFIED_PIXMAP, a default pixmap showing an arrow
pointing up is used.
XmNconvertCallback
Specifies a list of callbacks called when the Container is
asked to convert a selection. The type of the structure
whose address is passed to these callbacks is XmConvertCall‐
backStruct. The reason is XmCR_OK.
XmNdefaultActionCallback
Specifies a list of callbacks to call when the user double-
clicks an item or presses <Enter> or <Return> over an item.
The callback structure is XmContainerSelectCallbackStruct.
The reason is XmCR_DEFAULT_ACTION.
XmNdestinationCallback
Specifies a list of callbacks called when the Container is
the destination of a transfer operation. The type of the
structure whose address is passed to these callbacks is
XmDestinationCallbackStruct. The reason is XmCR_OK.
XmNdetailColumnHeading
Specifies a table of XmStrings to display as the headings to
columns. If NULL, or if XmNlayoutType is not XmDETAIL, no
heading is displayed.
XmNdetailColumnHeadingCount
Specifies a count of XmStrings in the table specified for
XmNdetailColumnHeading.
XmNdetailOrder
Specifies an array of Cardinals that indicate which column
detail information, and in which order, each Container child
will display its detail information. This resource is
ignored if XmNlayoutType is not XmDETAIL. If NULL, the the
default behavior is determined by XmNdetailOrderCount.
XmNdetailOrderCount
Specifies a count of Cardinals in the array specified for
XmNdetailOrder. If XmNdetailOrder is NULL and XmNdetai‐
lOrderCount is not 0, then each Container child displays its
detail information in order from column 1 to the XmNdetai‐
lOrderCount column number. If XmNdetailOrderCount is 0, then
a default is calculated from the detail order count informa‐
tion of each item accessed via the ContainerItem trait.
XmNdetailTabList
Indicates an XmTabList specifying the start of each column in
the XmDETAIL layout. If this resource is set to NULL, then
Container calculates an XmTabList. This resource is ignored
if XmNlayoutType is not XmDETAIL.
XmNentryViewType
Specifies the view type for all Container children. The view
type is specified for each item via the ContainerItem trait.
It can have one of the following values:
XmANY_ICON
No specification is made for Container children.
Children use their own default specifications.
XmLARGE_ICON
The view type for all children is XmLARGE_ICON.
XmSMALL_ICON
The view type for all children is XmSMALL_ICON.
XmNexpandedStatePixmap
Specifies the pixmap to display on a PushButton next to a
Container item with child items, when XmNoutlineButtonPolicy
is XmOUTLINE_BUTTON_PRESENT. XmNexpandedStatePixmap indi‐
cates that the child items are displayed. If set to XmUN‐
SPECIFIED_PIXMAP, a default pixmap showing an arrow pointing
down is used.
XmNfontList
Specifies the fontlist associated with XmContainer. The
fontlist is an obsolete construct and has been superseded by
the render table. It is included for compatibility with ear‐
lier versions of Motif, and for applications that do not eas‐
ily support render tables. The default fontlist is derived
from the default render table; and if both a fontlist and a
render table are specified, the render table takes prece‐
dence.
XmNlargeCellHeight
Specifies the height of a cell for XmGRID or XmCELLS spatial
style when XmNentryViewType is XmLARGE_ICON or XmANY_ICON.
XmNlargeCellWidth
Specifies the width of a cell for XmGRID or XmCELLS spatial
style when XmNentryViewType is XmLARGE_ICON or XmANY_ICON.
XmNlayoutType
Specifies the policy for laying out child widgets within the
Container. It can have one of the following values:
XmDETAIL Displays items in the same manner as when the
resource is XmOUTLINE, except that each item dis‐
plays detail information next to it.
XmOUTLINE Displays items in a tree configuration, in XmNposi‐
tionIndex within XmNentryParent order, with con‐
necting lines drawn to show their parent-child
relationships.
XmSPATIAL Displays items according to XmNspatialStyle. Items
with XmNentryParent values are not displayed.
XmNmarginHeight
Specifies the margin spacing at the top and bottom of the
Container.
XmNmarginWidth
Specifies the margin spacing at the left and right sides of
the Container.
XmNoutlineButtonPolicy
Specifies whether or not to display buttons for users to
expand and collapse the display of items. It can have one of
the following values:
XmOUTLINE_BUTTON_ABSENT
Do not display the outline buttons.
XmOUTLINE_BUTTON_PRESENT
Display the outline buttons.
XmNoutlineChangedCallback
Specifies a list of callbacks to call when an item's XmNout‐
lineState is changed. The callback structure is XmContainer‐
OutlineCallbackStruct. The reason is XmCR_COLLAPSED or
XmCR_EXPANDED, depending on the new value of XmNoutlineState.
XmNoutlineColumnWidth
Specifies the width of the first column displayed when XmN‐
layoutType is XmDETAIL. Specifies the preferred width of the
Container (without the margins) when XmNlayoutType is XmOUT‐
LINE. If not specified, Container will determine a default
value equal to the widest space necessary to display an
item's pixmap and XmNoutlineIndentation.
XmNoutlineIndentation
Specifies the distance to indent for the display of child
items when XmNlayoutType is XmOUTLINE or XmDETAIL.
XmNoutlineLineStyle
Specifies whether to draw lines between items with parent-
child relationships when XmNlayoutType is XmOUTLINE or XmDE‐
TAIL. It can have one of the following values:
XmNO_LINE Draws no line.
XmSINGLE Draws a line one pixel wide.
XmNprimaryOwnership
Specifies whether Container takes ownership of the primary
selection when a selection is made inside it. This resource
can take the following values:
XmOWN_NEVER
Never takes ownership.
XmOWN_ALWAYS
Always takes ownership.
XmOWN_MULTIPLE
Only takes ownership if more than one element has
been selected.
XmOWN_POSSIBLE_MULTIPLE
Only takes ownership if more than one element can
be selected at a time.
XmNrenderTable
Specifies the XmRenderTable that is inherited by all children
of the Container. The default is implementation dependent.
If both a render table and a fontlist are specified, the ren‐
der table will take precedence.
XmNselectColor
Specifies a Pixel that can be accessed by children of the
Container and used to indicate that the child is in a
selected state. In addition to a Pixel value, the following
symbolic values can be specified:
XmDEFAULT_SELECT_COLOR
Specifies a color between the background and the
bottom shadow color.
XmREVERSED_GROUND_COLORS
Forces the select color to the foreground color and
causes the default color of any text rendered over
the select color to be the background color.
HIGHLIGHT_COLOR
Forces the fill color to use the highlight color.
XmNselectedObjectCount
Specifies the number of widgets in the selected items list.
The value must be the number of items in XmNselectedObjects.
XmNselectedObjects
An array of widgets that represents the Container items that
are currently selected, either by the user or by the applica‐
tion.
If the application sets XmNselectedObjects to an array of
widgets, those array elements that are valid Container items
are selected.
XmNselectionCallback
Specifies a list of callbacks to call when an item is
selected. The callback structure is XmContainerSelectCall‐
backStruct. The reason is XmCR_SINGLE_SELECT,
XmCR_BROWSE_SELECT, XmCR_MULTIPLE_SELECT, or
XmCR_EXTENDED_MULTIPLE, depending on XmNselectionPolicy.
XmNselectionPolicy
Defines the interpretation of the selection action. This can
be one of the following values:
XmSINGLE_SELECT
Allows only single selections.
XmBROWSE_SELECT
Allows "drag and browse" selections.
XmMULTIPLE_SELECT
Allows multiple selections.
XmEXTENDED_SELECT
Allows extended selections.
XmNselectionTechnique
Specifies the selection technique to use when the Container
displays items in a 2-dimensional layout (XmNentryViewType is
XmLARGE_ICON or XmSMALL_ICON). In the XmDETAIL layout, the
XmNselectionTechnique resource is treated as XmTOUCH_ONLY. In
either case, it can have one of the following values:
XmMARQUEE Uses the Marquee technique only.
XmMARQUEE_EXTEND_START
Uses the Marquee technique only and extends the
Marquee rectangle around any item under the Marquee
start point.
XmMARQUEE_EXTEND_BOTH
Uses the Marquee technique only and extends the
Marquee rectangle around any items under the Mar‐
quee start and end points.
XmTOUCH_ONLY
Uses the Random-Swipe technique only if XmNlayout‐
Type is XmSPATIAL. Otherwise, uses the Range-Swipe
and Range-Click techniques.
XmTOUCH_OVER
If the selection action begins over an item and
XmNlayoutType is XmSPATIAL, uses the Random-Swipe
technique. If the selection action begins over an
item and XmNlayoutType is XmOUTLINE or XmDETAIL,
uses the Range-Swipe and Range-Click techniques.
Uses the Marquee technique if the select action
begins over an unoccupied area in the Container.
XmNsmallCellHeight
Specifies the height of a cell for XmGRID or XmCELLS spatial
style when XmNentryViewType is XmSMALL_ICON.
XmNsmallCellWidth
Specifies the width of a cell for XmGRID or XmCELLS spatial
style when XmNentryViewType is XmSMALL_ICON.
XmNspatialIncludeModel
Specifies the layout of an item when the item is managed in
the Container when XmNlayoutType is XmSPATIAL and XmNspatial‐
Style is XmGRID or XmCELLS. It can have one of the following
values:
XmAPPEND Places the item after the last occupied cell
according to XmNlayoutDirection.
XmCLOSEST Places the item in the free cell closest to the
position specified by XmNx and XmNy.
XmFIRST_FIT
Places the item in the first free cell according to
XmNlayoutDirection.
XmNspatialResizeModel
Specifies how Container will attempt to grow its dimensions
when XmNlayoutType is XmSPATIAL and XmNspatialStyle is XmGRID
or XmCELLS and there are not enough cells to contain a new
Container item. It can have one of the following values:
XmGROW_BALANCED
Container will request both width and height growth
from its parent.
XmGROW_MAJOR
Container will request growth in its major dimen‐
sion from its parent. Container's major dimension
is width when the precedence of XmNlayoutDirection
is horizontal, and height when vertical.
XmGROW_MINOR
Container will request growth in its minor dimen‐
sion from its parent. Container's minor dimension
is height when the precedence of XmNlayoutDirection
is horizontal, and width when vertical.
XmNspatialSnapModel
Specifies how Container will position an item within the cell
layout when XmNlayoutType is XmSPATIAL and XmNspatialStyle is
XmGRID or XmCELLS. It can have one of the following values:
XmCENTER Center the items as follows, depending on the value
of XmNentryViewType:
XmLARGE_ICON
The child is centered in the cell hori‐
zontally and baseline-aligned vertically.
XmSMALL_ICON
The child is centered in the cell verti‐
cally on its baseline and aligned with
the left or right of the cell horizon‐
tally, depending on the value of XmNlay‐
outDirection.
XmSNAP_TO_GRID
Position the item at the upper-left or upper-right
corner of the cell(s), depending on the value of
XmNlayoutDirection.
XmNONE Position the item according to the position speci‐
fied by XmNx and XmNy. If the position is not
within the coordinates of the cell(s), then posi‐
tion the item at the upper-left or upper-right cor‐
ner of the cell(s), depending on the value of XmN‐
layoutDirection.
XmNspatialStyle
Specifies the layout of Container items when XmNlayoutType is
XmSPATIAL. It can have one of the following values:
XmCELLS Lays out items within a grid of same-size cells.
Each item occupies as many cells as required to
contain the item dimensions.
XmGRID Lays out items within a grid of same-size cells.
Each item occupies only one cell. Items that are
larger than the cell size may overlap other items.
XmNONE Lays out items according to XmNx and XmNy.

XmNentryParent
Specifies the widget that is this item's logical parent. A
value of NULL indicates that this is a root-level item. Par‐
ent-child information is displayed only when the XmNlayout‐
Policy is XmOUTLINE or XmDETAIL.
XmNoutlineState
Specifies whether to display child items when XmNlayoutPolicy
is XmOUTLINE or XmDETAIL. It can have one of the following
values:
XmCOLLAPSED
Does not display child items.
XmEXPANDED
Displays child items.
XmNpositionIndex
Specifies the order of items in the Container for display.
When XmNlayoutType is XmOUTLINE or XmDETAIL, items are dis‐
played in XmNpositionIndex order within XmNentryParent.
Items that have an XmNentryParent resource are ignored when
XmNlayoutType is XmSPATIAL. If XmNpositionIndex is not spec‐
ified, it defaults to the XmNpositionIndex value plus 1 of
the item with the highest XmNpositionIndex that has the same
XmNentryParent if such an item exists; otherwise, it defaults
to 0.
Inherited Resources
Container inherits behavior and resources from the superclasses
described in the following tables. For a complete description of each
resource, refer to the reference page for that superclass.

Callback Information
A pointer to the following structure is passed to callbacks for XmNout‐
lineChangedCallback.
typedef struct
{
int reason;
XEvent * event;
Widget item;
unsigned char new_outline_state;
} XmContainerOutlineCallbackStruct;
reason Specifies the reason for the callback.
event Points to the XEvent that triggered the callback. It can be
NULL.
item Specifies the container item affected by the event.
new_outline_state
Specifies the next XmNoutlineState for item. The user can
change this value in the callback.
A pointer to the following structure is passed to callbacks for XmNde‐
faultActionCallback and XmNselectionCallback.
typedef struct
{
int reason;
XEvent * event;
WidgetList selected_items;
int selected_item_count;
unsigned char auto_selection_type;
} XmContainerSelectCallbackStruct;
reason Specifies the reason for the callback. It corresponds to the
XmNselectionPolicy at the time the selection was made, or
indicates that the default action should be taken.
event Points to the XEvent that triggered the callback. It can be
NULL.
selected_items
Specifies a list of items selected at the time of the event
that caused the callback. The selected_items field points to
a temporary storage space that is reused after the callback
is finished. Therefore, if an application needs to save the
selected list, it should copy the list into its own data
space.
selected_item_count
Specifies the number of items in the selected_items list.
This number must be positive or 0 (zero).
auto_selection_type
Indicates the cause of the selection when XmNautomaticSelec‐
tion is XmAUTO_SELECT. Valid values are the following:
XmAUTO_UNSET
Returned when XmNautomaticSelection is
XmNO_AUTO_SELECT.
XmAUTO_BEGIN
Indicates the beginning of automatic selection.
XmAUTO_MOTION
Indicates that there is a button drag selection.
XmAUTO_CANCEL
Indicates that the new selection is canceled.
XmAUTO_NO_CHANGE
Indicates that the currently selected item matches
the initial item.
XmAUTO_CHANGE
Indicates that the currently selected item does not
match the initial item.
A pointer to the following structure is passed to the XmNconvertCall‐
back procedures:
typedef struct
{
int reason;
XEvent *event;
Atom selection;
Atom target;
XtPointer source_data;
XtPointer location_data;
int flags;
XtPointer parm;
int parm_format;
unsigned long parm_length;
int status;
XtPointer value;
Atom type;
int format;
unsigned long length;
} XmConvertCallbackStruct;
reason Indicates why the callback was invoked.
event Points to the XEvent that triggered the callback. It can be
NULL.
selection Indicates the selection for which conversion is being
requested. Possible values are CLIPBOARD, PRIMARY, SEC‐
ONDARY, and _MOTIF_DROP.
target Indicates the conversion target.
source_data
Contains information about the selection source. When the
selection is _MOTIF_DROP, source_data is the DragContext.
Otherwise, it is NULL.
location_data
Contains information about the location of data to be con‐
verted. If the value is NULL, the data to be transferred
consists of the widget's current selection. Otherwise, it is
the widget ID of the item being transferred, or the widget ID
of the Container if all items are being transferred.
flags Indicates the status of the conversion. Following are the
possible values:
XmCONVERTING_NONE
This flag is currently unused.
XmCONVERTING_PARTIAL
The target widget was able to be converted, but
some data was lost.
XmCONVERTING_SAME
The conversion target is the source of the data to
be transferred.
XmCONVERTING_TRANSACT
This flag is currently unused.
parm Contains parameter data for this target. If no parameter
data exists, the value is NULL.
When selection is CLIPBOARD and target is _MOTIF_CLIP‐
BOARD_TARGETS or _MOTIF_DEFERRED_CLIPBOARD_TARGETS, the value
is the requested operation (XmCOPY, XmMOVE, or XmLINK).
parm_format
Specifies whether the data in parm should be viewed as a list
of char, short, or long quantities. Possible values are 0
(when parm is NULL), 8 (when the data in parm should be
viewed as a list of chars), 16 (when the data in parm should
be viewed as a list of shorts), or 32 (when the data in parm
should be viewed as a list of longs). Note that parm_format
symbolizes a data type, not the number of bits in each list
element. For example, on some machines, a parm_format of 32
means that the data in parm should be viewed as a list of
64-bit quantities, not 32-bit quantities.
parm_length
Specifies the number of elements of data in parm, where each
element has the size specified by parm_format. When parm is
NULL, the value is 0.
status An IN/OUT member that specifies the status of the conversion.
The initial value is XmCONVERT_DEFAULT. The callback proce‐
dure can set this member to one of the following values:
XmCONVERT_DEFAULT
The widget class conversion procedure, if any, is
called after the callback procedures return. If
the widget class conversion procedure produces any
data, it overwrites the data provided by the call‐
back procedures in the value member.
XmCONVERT_MERGE
The widget class conversion procedure, if any, is
called after the callback procedures return. If
the widget class conversion procedure produces any
data, it appends its data to the data provided by
the callback procedures in the value member. This
value is intended for use with targets that result
in lists of data, such as TARGETS.
XmCONVERT_DONE
The callback procedure has successfully finished
the conversion. The widget class conversion proce‐
dure, if any, is not called after the callback pro‐
cedures return.
XmCONVERT_REFUSE
The callback procedure has terminated the conver‐
sion process without completing the requested con‐
version. The widget class conversion procedure, if
any, is not called after the callback procedures
return.
value An IN/OUT parameter that contains any data that the callback
procedure produces as a result of the conversion. The ini‐
tial value is NULL. If the callback procedure sets this mem‐
ber, it must ensure that the type, format, and length members
correspond to the data in value. The callback procedure is
responsible for allocating, but not for freeing, memory when
it sets this member.
type An IN/OUT parameter that indicates the type of the data in
the value member. The initial value is INTEGER.
format An IN/OUT parameter that specifies whether the data in value
should be viewed as a list of char, short, or long quanti‐
ties. The initial value is 8. The callback procedure can
set this member to 8 (for a list of char), 16 (for a list of
short), or 32 (for a list of long).
length An IN/OUT member that specifies the number of elements of
data in value, where each element has the size symbolized by
format. The initial value is 0 (zero).
A pointer to the following callback structure is passed to the XmNdes‐
tinationCallback procedures:
typedef struct
{
int reason;
XEvent *event;
Atom selection;
XtEnum operation;
int flags;
XtPointer transfer_id;
XtPointer destination_data;
XtPointer location_data;
Time time;
} XmDestinationCallbackStruct;
reason Indicates why the callback was invoked.
event Points to the XEvent that triggered the callback. It can be
NULL.
selection Indicates the selection for which data transfer is being
requested. Possible values are CLIPBOARD, PRIMARY, SEC‐
ONDARY, and _MOTIF_DROP.
operation Indicates the type of transfer operation requested.
· When the selection is PRIMARY, possible values are
XmMOVE, XmCOPY, and XmLINK.
· When the selection is SECONDARY or CLIPBOARD, possible
values are XmCOPY and XmLINK.
· When the selection is _MOTIF_DROP, possible values are
XmMOVE, XmCOPY, XmLINK, and XmOTHER. A value of
XmOTHER means that the callback procedure must get fur‐
ther information from the XmDropProcCallbackStruct in
the destination_data member.
flags Indicates whether or not the destination widget is also the
source of the data to be transferred. Following are the pos‐
sible values:
XmCONVERTING_NONE
The destination widget is not the source of the
data to be transferred.
XmCONVERTING_SAME
The destination widget is the source of the data to
be transferred.
transfer_id
Serves as a unique ID to identify the transfer transaction.
destination_data
Contains information about the destination. When the selec‐
tion is _MOTIF_DROP, the callback procedures are called by
the drop site's XmNdropProc, and destination_data is a
pointer to the XmDropProcCallbackStruct passed to the XmN‐
dropProc procedure. When the selection is SECONDARY, desti‐
nation_data is an Atom representing a target recommmended by
the selection owner for use in converting the selection.
Otherwise, destination_data is NULL.
location_data
Contains information about the location where data is to be
transferred. The value is always NULL when the selection is
SECONDARY or CLIPBOARD. If the value is NULL, the data is to
be inserted at the widget's cursor position. Otherwise, the
value is a pointer to an XPoint structure containing the x
and y coordinates at the location where the data is to be
transferred. Once XmTransferDone procedures start to be
called, location_data will no longer be stable.
time Indicates the time when the transfer operation began.
Translations
The XmContainer translations are listed below.
The following key names are listed in the X standard key event transla‐
tion table syntax. This format is the one used by Motif to specify the
widget actions corresponding to a given key. A brief overview of the
format is provided under VirtualBindings(3). For a complete descrip‐
tion of the format, please refer to the X Toolkit Instrinsics Documen‐
tation.

The Container button event translations are modified when Display's
XmNenableBtn1Transfer resource does not have a value of XmOFF (in other
words, it is either XmBUTTON2_TRANSFER or XmBUTTON2_ADJUST). This
option allows the actions for selection and transfer to be integrated
on <Btn1>, and the actions for extending the selection can be bound to
<Btn2>. The actions for <Btn1> that are defined in the preceding list
still apply when the <Btn1> event occurs over text that is not
selected. The following actions apply when the <Btn1> event occurs over
text that is selected:
~c ~s ~m ~a <Btn1Down>:
ContainerHandleBtn1Down(ContainerBeginSelect,Copy)
c ~s ~m ~a <Btn1Down>:
ContainerHandleBtn1Down(ContainerBeginToggle,Copy)

When Display's XmNenableBtn1Transfer resource has a value of XmBUT‐
TON2_ADJUST, the following actions apply:
~c ~s ~m ~a <Btn2Down>:
ContainerHandleBtn2Down(ContainerStartTransfer,Copy)
c s ~m ~a <Btn2Down>:

Action Routines
The Container action routines are described below. The current selec‐
tions are always shown with the background color specified by the XmNs‐
electColor resource.
ContainerActivate():
This action calls XmNdefaultActionCallback with reason
XmCR_DEFAULT_ACTION.
ContainerBeginExtend():
Simply returns if XmNselectionPolicy is XmSINGLE_SELECT or
XmBROWSE_SELECT. Simply returns if XmNlayoutType is XmSPA‐
TIAL.
Otherwise, this action sets the selection state of all items
between the anchor item and the item under the pointer to the
selection state of the anchor item. The location cursor is
moved to the item under the pointer. If XmNautomaticSelec‐
tion is XmAUTO_SELECT, the XmNselectionCallback(s) is called
with either XmCR_MULTIPLE_SELECT or XmCR_EXTENDED_SELECT as
the reason depending on XmNselectionPolicy, and with
auto_selection_type XmAUTO_CHANGE.
ContainerBeginSelect():
If this is a second ContainerBeginSelect() action that has
occurred within the time specified by the display's mul‐
ticlick time, this action calls XmNdefaultActionCallback with
reason XmCR_DEFAULT_ACTION and returns.
Otherwise, processing depends on the value of XmNselection‐
Policy as follows:
XmSINGLE_SELECT
This action deselects all items and toggles the
item (if any) under the pointer.
XmBROWSE_SELECT
This action deselects all items and toggles the
item (if any) under the pointer. This item is now
the anchor item for further selection. If XmNauto‐
maticSelection is XmAUTO_SELECT and a change in any
item's selection state is made, the XmNselection‐
Callback(s) is called with reason
XmCR_BROWSE_SELECT and auto_selection_type
XmAUTO_BEGIN.
XmMULTIPLE_SELECT
If the pointer is over an item and XmNselection‐
Technique is not XmMARQUEE, this action toggles the
selection state of that item. The item becomes the
anchor item for further selection. If XmNselec‐
tionTechnique is XmMARQUEE, XmMARQUEE_EXTEND_START,
or XmMARQUEE_EXTEND_BOTH, this action sets the
start point for the Marquee rectangle. If XmNse‐
lectionTechnique is XmMARQUEE_EXTEND_START or
XmMARQUEE_EXTEND_BOTH and the pointer is over an
item, this action draws the Marquee rectangle
around the item. If XmNautomaticSelection is
XmAUTO_SELECT, the XmNselectionCallback(s) is
called with reason XmCR_MULTIPLE_SELECT and
auto_selection_type XmAUTO_BEGIN.
XmEXTENDED_SELECT
All items are first deselected. Processing is then
identical to the case where XmNselectionPolicy is
XmMULTIPLE_SELECT, except that XmCR_EXTENDED_SELECT
is the callback reason given if XmNselectionCall‐
back is called.
ContainerBeginToggle():
Simply returns if XmNselectionPolicy is XmSINGLE_SELECT or
XmBROWSE_SELECT.
Otherwise, if the pointer is over an item and XmNselection‐
Technique is not XmMARQUEE, this action toggles the selection
state of that item. The item becomes the anchor item for
further selection. If XmNselectionTechnique is XmMARQUEE,
XmMARQUEE_EXTEND_START, or XmMARQUEE_EXTEND_BOTH this action
sets the start point for the Marquee rectangle. If XmNselec‐
tionTechnique is XmMARQUEE_EXTEND_START or XmMAR‐
QUEE_EXTEND_BOTH and the pointer is over an item, this action
draws the Marquee rectangle around the item. If XmNautomat‐
icSelection is XmAUTO_SELECT, the XmNselectionCallback(s) is
called with either XmCR_MULTIPLE_SELECT or
XmCR_EXTENDED_SELECT as the reason, depending on XmNselec‐
tionPolicy, and with auto_selection_type XmAUTO_BEGIN.
ContainerButtonMotion():
Processing depends on the value of XmNselectionPolicy, as
follows:
XmSINGLE_SELECT
This action simply returns to the caller.
XmBROWSE_SELECT
Simply returns if this action follows a Container‐
BeginExtend() action or ContainerBeginToggle()
action.
If the pointer is no longer over the current anchor
item, this action toggles the current anchor item
and then toggles the item under the pointer (if
any) and makes it the new anchor item for further
processing. If XmNautomaticSelection is
XmAUTO_SELECT and a change in any item's selection
state is made, the XmNselectionCallback(s) is
called with reason XmCR_BROWSE_SELECT and
auto_selection_type XmAUTO_MOTION.
XmMULTIPLE_SELECT
If a previous action has set a Marquee rectangle
start point, this action draws the Marquee rectan‐
gle between the current pointer position and the
Marquee start point. If the XmNselectionTechnique
is XmMARQUEE_EXTEND_BOTH and the pointer is over an
item, the end point of the Marquee rectangle is
extended to include the item. The selection states
of all items within the Marquee rectangle are tog‐
gled to match the state of the anchor item.
If no Marquee rectangle start point is set and the
pointer is over an item, processing depends on the
XmNlayoutType resource. The anchor item from the
previous action is used. If XmNlayoutType is XmSPA‐
TIAL, the selection state of the item under the
pointer is toggled to match the selection state of
the anchor item. If XmNlayoutType is XmOUTLINE or
XmDETAIL, the selection state of all items between
the anchor item and the item under the pointer are
toggled to match the selection state of the anchor
item.
If XmNautomaticSelection is XmAUTO_SELECT and a
change in any item's selection state is made, the
XmNselectionCallback(s) is called with reason
XmCR_MULTIPLE_SELECT and auto_selection_type
XmAUTO_MOTION.
XmEXTENDED_SELECT
Processing is identical to the case where XmNselec‐
tionPolicy is XmMULTIPLE_SELECT, except that
XmCR_EXTENDED_SELECT is the callback reason given
if XmNselectionCallback is called.
ContainerCancel():
If a selection is in progress, this action restores selection
states of all items to their state before the selection
began. If XmNautomaticSelection is True and a change in any
item's selection state is made, the XmNselectionCallback is
called with reason XmCR_BROWSE_SELECT, XmMULTIPLE_SELECT, or
XmCR_EXTENDED_SELECT depending on the XmNselectionPolicy
resource and auto_selection_type XmAUTO_CANCEL.
ContainerDeselectAll():
This action deselects all items and calls XmNselectionCall‐
back with reason depending on XmNselectionPolicy.
ContainerEndExtend():
Simply returns if XmNselectionPolicy is XmSINGLE_SELECT or
XmBROWSE_SELECT. Simply returns if XmNlayoutType is XmSPA‐
TIAL.
Otherwise, if XmNautomaticSelection is XmNO_AUTO_SELECT,
XmNselectionCallback(s) is called with either XmCR_MULTI‐
PLE_SELECT or XmCR_EXTENDED_SELECT as the reason depending on
XmNselectionPolicy. If XmNautomaticSelection is
XmAUTO_SELECT and no change is made in any item's selection
state by this action, XmNselectionCallback(s) is called with
either XmCR_MULTIPLE_SELECT or XmCR_EXTENDED_SELECT as the
reason depending on XmNselectionPolicy and auto_selec‐
tion_type XmAUTO_CHANGE. If XmNautomaticSelection is
XmAUTO_SELECT and this action makes no change in any item's
selection state, XmNselectionCallback(s) is called with
either XmCR_MULTIPLE_SELECT or XmCR_EXTENDED_SELECT as the
reason depending on XmNselectionPolicy and auto_selec‐
tion_type XmAUTO_NO_CHANGE.
ContainerEndSelect():
Processing depends on the value of XmNselectionPolicy, as
follows:
XmSINGLE_SELECT
This action calls XmNselectionCallback with reason
XmCR_SINGLE_SELECT.
XmBROWSE_SELECT
If the pointer is no longer over the current anchor
item, this action toggles the current anchor item
and then toggles the item under the pointer (if
any). If XmNautomaticSelection is XmNO_AUTO_SELECT,
the XmNselectionCallback(s) is called with reason
XmCR_BROWSE_SELECT. If XmNautomaticSelection is
XmAUTO_SELECT and a change in any item's selection
state is made, XmNselectionCallback(s) is called
with reason XmCR_BROWSE_SELECT and auto_selec‐
tion_type XmAUTO_CHANGE. If XmNautomaticSelection
is XmAUTO_SELECT and no change is made in any
item's selection state by this action, XmNselec‐
tionCallback(s) is called with reason
XmCR_BROWSE_SELECT and auto_selection_type
XmAUTO_NO_CHANGE.
XmMULTIPLE_SELECT
This action first performs the same processing as
the ContainerButtonMotion() action, except that
XmNselectionCallback is not called. If XmNautomat‐
icSelection is XmNO_AUTO_SELECT, the XmNselection‐
Callback(s) is called with reason XmCR_MULTI‐
PLE_SELECT. If XmNautomaticSelection is
XmAUTO_SELECT and a change in any item's selection
state is made, the XmNselectionCallback(s) is
called with reason XmCR_MULTIPLE_SELECT and
auto_selection_type XmAUTO_CHANGE. If XmNautomat‐
icSelection is XmAUTO_SELECT and this action makes
no change in any item's selection state, XmNselec‐
tionCallback(s) is called with reason XmCR_MULTI‐
PLE_SELECT and auto_selection_type
XmAUTO_NO_CHANGE.
XmEXTENDED_SELECT
This action first performs the same processing as
the ContainerButtonMotion() action, except that
XmNselectionCallback is not called. If XmNautomat‐
icSelection is XmNO_AUTO_SELECT, the XmNselection‐
Callback(s) is called with reason
XmCR_EXTENDED_SELECT. If XmNautomaticSelection is
XmAUTO_SELECT and a change in any item's selection
state is made, XmNselectionCallback(s) is called
with reason XmCR_EXTENDED_SELECT and auto_selec‐
tion_type XmAUTO_CHANGE. If XmNautomaticSelection
is XmAUTO_SELECT and this action makes no change in
any item's selection state, XmNselectionCallback(s)
is called with reason XmCR_EXTENDED_SELECT and
auto_selection_type XmAUTO_NO_CHANGE.
ContainerEndToggle():
Simply returns if XmNselectionPolicy is XmSINGLE_SELECT or
XmBROWSE_SELECT. If XmNselectionPolicy is XmMULTIPLE_SELECT
or XmEXTENDED_SELECT, this action performs the same process‐
ing as the ContainerEndSelect() action.
ContainerEndTransfer()::
If the elapsed time since a ContainerStartTransfer() action
has occurred exceeds the time span specified by the display's
multiclick time, this action returns.
Otherwise, the ContainerPrimaryCopy(), ContainerPrima‐
ryLink(), or ContainerPrimaryMove() action is invoked,
depending on the value of the operation parameter saved by
ContainerStartTransfer().
ContainerExpandOrCollapse(Left|Right|Collapse|Expand):
This action changes the value of the XmNoutlineState of the
current focus widget. If the argument value is Collapse or
Left, the XmNoutlineState resource value is set to XmCOL‐
LAPSED. If the argument value is Expand or Right, the XmNout‐
lineState resource value is set to XmEXPANDED.
If the argument is Left or Right and the layout is right to
left, then the setting of the XmNoutlineState value is
reversed from that described in the preceding paragraph.
Simply returns if XmNlayoutType is XmSPATIAL.
ContainerExtend():
Processing depends on the value of XmNselectionPolicy, as
follows:
If the selection policy is XmSINGLE_SELECT or
XmBROWSE_SELECT, this action returns. If XmNlayoutType is
XmSPATIAL, this action returns.
If the selection policy is XmMULTIPLE_SELECT, this action
sets the selection state of all items between the anchor item
and the location cursor to the selection state of the anchor
item.
If the selection policy is XmEXTENDED_SELECT and the Con‐
tainer is in Normal Mode, this action deselects all items and
selects all items between the anchor item and the location
cursor. If the selection policy is XmEXTENDED_SELECT and the
Container is in Add Mode, this action sets the selection
state of all items between the anchor item and the location
cursor to the selection state of the anchor item.
XmNselectionCallback is called with reason XmCR_MULTI‐
PLE_SELECT or XmCR_EXTENDED_SELECT depending on XmNselection‐
Policy.
ContainerExtendCursor(Left|Right|Up|Down):
Processing depends on the value of XmNselectionPolicy, as
follows:
If the selection policy is XmSINGLE_SELECT or
XmBROWSE_SELECT, this action returns. If XmNlayoutType is
XmSPATIAL, this action returns.
This action moves the location cursor one item in the indi‐
cated direction, if possible. If the value of the argument
string is First or Last, this action moves the location cur‐
sor to the indicated item. For other values of the argument
string, the location cursor is not affected.
If the selection policy is XmMULTIPLE_SELECT, this action
sets the selection state of all items between the anchor item
and the location cursor to the selection state of the anchor
item.
If the selection policy is XmEXTENDED_SELECT and the Con‐
tainer is in Normal Mode, this action deselects all items and
selects all items between the anchor item and the location
cursor. If the selection policy is XmEXTENDED_SELECT and the
Container is in Add Mode, this action sets the selection
state of all items between the anchor item and the location
cursor to the selection state of the anchor item.
XmNselectionCallback is called with reason XmCR_MULTI‐
PLE_SELECT or XmCR_EXTENDED_SELECT depending on XmNselection‐
Policy.
ContainerHandleBtn1Down(string)
When Display's XmNenableBtn1Transfer resource is not XmOFF,
the actions for selection and transfer are integrated on
<Btn1>. If the pointer is over an unselected item or back‐
ground, the item is first selected before the transfer is
started. Otherwise, if the item is already selected, the
transfer is started. The value of string can be one of the
following actions:
· ContainerBeginSelect,Copy
· ContainerBeginToggle,Copy
· ContainerNoop,Link
· ContainerBeginExtend,Move
ContainerHandleBtn1Motion(string)
When Display's XmNenableBtn1Transfer resource is not XmOFF,
the actions for selection and transfer are integrated on
<Btn1>. When this action is invoked, and a selection is in
progress, a drag is performed. Otherwise, the default action
as specified in string is performed. The value of string can
be ContainerButtonMotion.
ContainerHandleBtn1Up(string)
If a Button 1 transfer was in progress, then when this action
is invoked, that transfer is cancelled. Otherwise, the
default action as specified in string is performed. The value
of string can be one of the following actions:
· ContainerEndSelect
· ContainerEndToggle
· ContainerEndExtend
ContainerHandleBtn2Down(string)
When Display's XmNenableBtn1Transfer resource has a value of
XmBUTTON2_ADJUST, the actions for extending selection are
bound on <Btn2>. Otherwise, the action that is performed
depends on the value of string, which can be one of the fol‐
lowing actions:
· ContainerStartTransfer,Copy
· ContainerStartTransfer,Link
· ContainerStartTransfer,Move
ContainerHandleBtn2Motion(string)
When Display's XmNenableBtn1Transfer resource is not XmBUT‐
TON2_ADJUST, and a selection is in progress, a drag is per‐
formed. Otherwise, the default action that is performed
depends on the value of string, which can be ContainerButton‐
Motion.
ContainerHandleBtn2Up(string)
When Display's XmNenableBtn1Transfer resource has a value of
XmBUTTON2_ADJUST, this action ends an extend. Otherwise, the
action that is performed depends on the value of string,
which can be ContainerEndTransfer.
ContainerMoveCursor(Left|Right|Up|Down|First|Last):
If the argument is Left, Right, Up, or Down, this action
moves the location cursor one item in the indicated direc‐
tion, if possible. If the value of the argument string is
First or Last, this action moves the location cursor to the
indicated item. Any other arguments are ignored.
If XmNselectionPolicy is XmBROWSE_SELECT, or if XmNselection‐
Policy is XmEXTENDED_SELECT and the Container is in Normal
Mode, this action deselects all items, selects the item at
the location cursor, and calls XmNselectionCallback with the
reason depending on XmNselectionPolicy.
ContainerPrimaryCopy():
This action requests that primary selection data be copied to
the Container. This action calls the XmNdestinationCallback
procedures for the PRIMARY selection and the XmCOPY opera‐
tion. By default, the Container does not do any transfer,
and copying the selection is the responsibility of the XmN‐
destinationCallback procedures.
ContainerPrimaryLink():
This action requests that primary selection data be linked to
the Container. This action calls the XmNdestinationCallback
procedures for the PRIMARY selection and the XmLINK opera‐
tion. By default, the Container does not do any transfer,
and linking the selection is the responsibility of the XmN‐
destinationCallback procedures.
ContainerPrimaryMove():
This action requests that primary selection data be copied to
the Container and deleted from the primary source. This
action calls the XmNdestinationCallback procedures for the
PRIMARY selection and the XmMOVE operation. By default, the
Container does not do any transfer, and moving the selection
is the responsibility of the XmNdestinationCallback proce‐
dures. If the transfer is successful, this action then calls
the selection owner's XmNconvertCallback procedures for the
PRIMARY selection and the DELETE target.
ContainerSelect():
Processing depends on the value of XmNselectionPolicy, as
follows:
If the selection policy is XmSINGLE_SELECT or
XmBROWSE_SELECT, this action deselects all items and selects
the item at the location cursor.
If the selection policy is XmMULTIPLE_SELECT, this action
toggles the selection state of the item at the location cur‐
sor. This item becomes the anchor item for further selec‐
tions.
If the selection policy is XmEXTENDED_SELECT and the Con‐
tainer is in Normal Mode, this action deselects all items and
selects the item at the location cursor. If the selection
policy is XmEXTENDED_SELECT and the Container is in Add Mode,
this action toggles the selection state of the item at the
location cursor. The selected/toggled item becomes the
anchor item for further selections.
XmNselectionCallback is called with the reason depending on
XmNselectionPolicy.
ContainerSelectAll():
If XmNselectionPolicy is XmSINGLE_SELECT or XmBROWSE_SELECT,
this action deselects all items and selects the item at the
location cursor position.
If XmNselectionPolicy is XmMULTIPLE_SELECT or XmEX‐
TENDED_SELECT, this action selects all items.
XmNselectionCallback is called with the reason depending on
the value of XmNselectionCallback.
ContainerStartTransfer(Copy|Move|Link):
This action saves the event and the operation specified in
the argument string for use by subsequent actions. If no
ContainerEndTransfer() actions occur within the time span
specified by the display's multiclick time and if XmNlayout‐
Type is XmSPATIAL, this action creates a DragContext and
starts a drag transfer by using string to specify the trans‐
fer operation. If no argument string is specified, Copy is
the default value.
Unless default drag and drop behavior has been overridden by
a XmNconvertCallback procedure, if the drop operation occurs
within the Container, then the item(s) being dragged are
relocated at the position of the drop operation. If the item
targeted by the Drag operation is not in the selected state,
then only that item is moved. If the item is in the selected
state, however, all items in the selected state are moved.
ContainerToggleMode():
If XmNselectionPolicy is XmEXTENDED_SELECT, this action tog‐
gles the Container between Normal Mode and Add Mode.
Additional Behavior
The Container widget has the following additional behavior:
<Btn1Down>(2+)
If a button click is followed by another button click within
the time span specified by the display's multiclick time, the
Container interprets that as a double-click and calls the
XmNdefaultActionCallback callbacks.
<FocusIn>:
If the focus policy is explicit, sets the focus and draws the
location cursor.
<FocusOut>:
If the focus policy is explicit, removes the focus and erases
the location cursor.
