NAMEXmRendition — The Rendition registry
SYNOPSIS
#include <Xm/Xm.h>
XmRenditionDESCRIPTIONXmRendition is a pseudo widget used for the rendering of XmStrings.
XmRendition has two parts: XmStringTag and rendering information. The
XmStringTag part can be matched with an XmStringTag associated with a
LOCALE, CHARSET, or RENDITION[BEGIN|END] component within XmString.
The rendering information contains information about the font or
fontset, colors, tabs, and lines to be used in rendering a text compo‐
nent.
If a resource in a rendition is unspecified, usually by setting it to
XmAS_IS or XmUNSPECIFIED_PIXEL, then the value to be used for that
resource is the value of the immediately preceeding rendition in
XmString. If that value is unspecified, then the preceding value is
used, and so on. If no renditions specify a value for a resource, then
a default value will be used.
Classes
XmRendition does not inherit from any widget class.
New Resources
The following table defines a set of widget resources used by the pro‐
grammer to specify data. 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 .Xde‐
faults 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 XmRenditionUpdate (S),
retrieved by using XmRenditionRetrieve (G), or is not applicable (N/A).

XmNrenditionBackground
Specifies the background drawing color. A value of XmUNSPECI‐
FIED_PIXEL indicates that the background is not specified for
this rendition.
XmNfont Specifies the actual font or fontset to be used by this ren‐
dition. The value of this resource, if set to other than
XmAS_IS, will be used regardless of the settings of the other
font resources. Setting this resource will force XmNloadModel
to be XmLOAD_IMMEDIATE. If this resource is not initially
set, then it will be set subsequently by the rendition when‐
ever the font or fontset specified by XmNfontName is loaded.
If both XmNfontName and XmNfont are specified in a resource
file, the XmNfont specification will take precedence.
XmNfontName
Specifies an X Logical Font Description (XLFD) string, which
is interpreted either as a font name or as a base font name
list. A base font name list is a comma-separated and NULL-
terminated string. A value of XmAS_IS indicates that the font
is not specified for this rendition. If both XmNfontName and
XmNfont are specified in a resource file, the XmNfont speci‐
fication will take precedence.
XmNfontType
Specifies whether the XmNfontName resource refers to a font
name or to a base font name list. Valid values are
XmFONT_IS_FONT and XmFONT_IS_FONTSET.
XmNrenditionForeground
Specifies the foreground drawing color. A value of XmUNSPECI‐
FIED_PIXEL indicates that the foreground is not specified for
this rendition.
XmNloadModel
Specifies whether the font or fontset specified by XmNfont‐
Name is to be loaded when the rendition is created
(XmLOAD_IMMEDIATE) or only when the font is required to ren‐
der an XmString segment (XmLOAD_DEFERRED). Note that speci‐
fying XmLOAD_IMMEDIATE for XmNloadModel is valid only if XmN‐
fontName is specified, in which case the specified font will
be loaded on creation, or if XmNfont is specified, in which
case the font is already loaded. XmLOAD_DEFERRED is only
valid when XmNfontName is specified.
XmNstrikethruType
Specifies the type of line to be used to strike through a
text segment. Valid values are XmNO_LINE, XmSINGLE_LINE,
XmDOUBLE_LINE, XmSINGLE_DASHED_LINE, and XmDOU‐
BLE_DASHED_LINE. A value of XmAS_IS indicates that the
strike-through type is not specified for this rendition.
XmNtabList
Specifies the tab list to be used in rendering compound
strings containing tab components.
XmNtag Specifies the tag string to be used in matching the rendi‐
tions with other renditions or with XmStringTag components in
XmStrings. This resource must always be specified. That is,
NULL is not a legal value but the empty string is. This
resource is automatically set to the value of the tag parame‐
ter in the XmRenditionCreate call.
XmNunderlineType
Specifies the type of line to be used to underline a text
segment. Valid values are XmNO_LINE, XmSINGLE_LINE, XmDOU‐
BLE_LINE, XmSINGLE_DASHED_LINE, and XmDOUBLE_DASHED_LINE. A
value of XmAS_IS indicates that the underline type is not
specified for this rendition.
