NAMEXmDrawnButton — The DrawnButton widget class
SYNOPSIS
#include <Xm/DrawnB.h>
DESCRIPTION
The DrawnButton widget consists of an empty widget window surrounded by
a shadow border. It provides the application developer with a graphics
area that can have PushButton input semantics.
Callback types are defined for widget exposure and widget resize to
allow the application to redraw or reposition its graphics. If the
DrawnButton widget has a highlight and shadow thickness, the applica‐
tion should not draw in that area. To avoid drawing in the highlight
and shadow area, create the graphics context with a clipping rectangle
for drawing in the widget. The clipping rectangle should take into
account the size of the widget's highlight thickness and shadow.
DrawnButton uses the XmQTmenuSystem and XmQTspecifyRenderTable traits,
and holds the XmQTactivatable trait.
Classes
BulletinBoard inherits behavior, resources, and traits from the Core,
Composite, Constraint, and XmManager classes.
The class pointer is xmDrawnButtonWidgetClass.
The class name is XmDrawnButton.
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 if 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).

XmNactivateCallback
Specifies the list of callbacks that is called when the wid‐
get becomes selected. The reason sent by the callback is
XmCR_ACTIVATE. This callback uses the XmQTactivatable trait.
XmNarmCallback
Specifies the list of callbacks that is called when the wid‐
get becomes armed. The reason sent by the callback is
XmCR_ARM.
XmNdisarmCallback
Specifies the list of callbacks that is called when the wid‐
get becomes disarmed. The reason sent by the callback is
XmCR_DISARM.
XmNexposeCallback
Specifies the list of callbacks that is called when the wid‐
get receives an exposure event. The reason sent by the call‐
back is XmCR_EXPOSE.
XmNmultiClick
If a button click is followed by another button click within
the time span specified by the display's multiclick time, and
this resource is set to XmMULTICLICK_DISCARD, the second
click is not processed. If this resource is set to XmMUL‐
TICLICK_KEEP, the event is processed and click_count is
incremented in the callback structure. When the button is
not in a menu, the default value is XmMULTICLICK_KEEP.
XmNpushButtonEnabled
Enables or disables the 3-dimensional shadow drawing as in
PushButton.
XmNresizeCallback
Specifies the list of callbacks that is called when the wid‐
get receives a resize event. The reason sent by the callback
is XmCR_RESIZE. The event returned for this callback is NULL.
XmNshadowType
Describes the drawing style for the DrawnButton. This
resource can have the following values:
XmSHADOW_IN
Draws the DrawnButton so that the shadow appears
inset. This means that the bottom shadow visuals
and top shadow visuals are reversed.
XmSHADOW_OUT
Draws the DrawnButton so that the shadow appears
outset.
XmSHADOW_ETCHED_IN
Draws the DrawnButton using a double line. This
gives the effect of a line etched into the window.
The thickness of the double line is equal to the
value of XmNshadowThickness.
XmSHADOW_ETCHED_OUT
Draws the DrawnButton using a double line. This
gives the effect of a line coming out of the win‐
dow. The thickness of the double line is equal to
the value of XmNshadowThickness.
Inherited Resources
DrawnButton 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 each callback:
typedef struct
{
int reason;
XEvent * event;
Window window;
int click_count;
} XmDrawnButtonCallbackStruct;
reason Indicates why the callback was invoked.
event Points to the XEvent that triggered the callback. This is
NULL for XmNresizeCallback.
window Is set to the window ID in which the event occurred.
click_count
Contains the number of clicks in the last multiclick sequence
if the XmNmultiClick resource is set to XmMULTICLICK_KEEP,
otherwise it contains 1. The activate callback is invoked
for each click if XmNmultiClick is set to XmMULTICLICK_KEEP.
Translations
XmDrawnButton includes translations from Primitive. Additional
XmDrawnButton translations are described in the following list. The
following key names are listed in the X standard key event translation
table syntax. This format is the one used by Motif to specify the wid‐
get actions corresponding to a given key. A brief overview of the for‐
mat is provided under VirtualBindings(3). For a complete description
of the format, please refer to the X Toolkit Instrinsics Documentation.

Action Routines
The XmDrawnButton action routines are
Activate():
If XmNpushButtonEnabled is True, redraws the shadow in the
unselected state; otherwise, redraws the shadow according to
XmNshadowType. If the pointer is within the DrawnButton,
calls the XmNactivateCallback callbacks.
Arm(): If XmNpushButtonEnabled is True, redraws the shadow in the
selected state; otherwise, redraws the shadow according to
XmNshadowType. Calls the callbacks for XmNarmCallback.
ArmAndActivate():
If XmNpushButtonEnabled is True, redraws the shadow in the
selected state; otherwise, redraws the shadow according to
XmNshadowType. Calls the callbacks for XmNarmCallback.
If XmNpushButtonEnabled is True, the shadow is redrawn in the
unselected state; otherwise, the shadow is redrawn according
to XmNshadowType. The callbacks for XmNactivateCallback and
XmNdisarmCallback are called. These actions happen either
immediately or at a later time.
ButtonTakeFocus():
Causes the PushButton to take keyboard focus when
Ctrl<Btn1Down> is pressed, without activating the widget.
Disarm(): Marks the DrawnButton as unselected and calls the callbacks
for XmNdisarmCallback.
Help(): Calls the callbacks for XmNhelpCallback if any exist. If
there are no help callbacks for this widget, this action
calls the help callbacks for the nearest ancestor that has
them.
MultiActivate():
If XmNmultiClick is XmMULTICLICK_DISCARD, this action does
nothing.
If XmNmultiClick is XmMULTICLICK_KEEP, this action increments
click_count in the callback structure. If XmNpushButtonEn‐
abled is True, this action redraws the shadow in the unse‐
lected state; otherwise, it redraws the shadow according to
XmNshadowType. If the pointer is within the DrawnButton,
this action calls the XmNactivateCallback callbacks and calls
the callbacks for XmNdisarmCallback.
MultiArm():
If XmNmultiClick is XmMULTICLICK_DISCARD, this action does
nothing.
If XmNmultiClick is XmMULTICLICK_KEEP and if XmNpushButtonEn‐
abled is True, this action redraws the shadow in the selected
state; otherwise, it redraws the shadow according to XmNshad‐
owType and calls the callbacks for XmNarmCallback.
Additional Behavior
This widget has the following additional behavior:
<EnterWindow>:
Draws the shadow in its selected state if XmNpushButtonEn‐
abled is True and if the cursor leaves and re-enters the win‐
dow while BSelect is pressed.
<LeaveWindow>:
Draws the shadow in its unselected state if XmNpushButtonEn‐
abled is True and if the cursor leaves the window while BSe‐
lect is pressed.
