NAME
XmRendition -- The Rendition registry
SYNOPSIS
#include <Xm/Xm.h>
XmRendition
DESCRIPTION
XmRendition 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
component.
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
programmer 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 .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
XmRenditionUpdate (S), retrieved by using XmRenditionRetrieve (G), or
is not applicable (N/A).

XmNrenditionBackground
Specifies the background drawing color. A value of
XmUNSPECIFIED_PIXEL indicates that the background is not
specified for this rendition.
XmNfont Specifies the actual font or fontset to be used by this
rendition. 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
whenever 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
specification 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
XmUNSPECIFIED_PIXEL indicates that the foreground is not
specified for this rendition.
XmNloadModel
Specifies whether the font or fontset specified by
XmNfontName is to be loaded when the rendition is created
(XmLOAD_IMMEDIATE) or only when the font is required to
render an XmString segment (XmLOAD_DEFERRED). Note that
specifying XmLOAD_IMMEDIATE for XmNloadModel is valid only if
XmNfontName 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
XmDOUBLE_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
renditions 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 parameter 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,
XmDOUBLE_LINE, XmSINGLE_DASHED_LINE, and
XmDOUBLE_DASHED_LINE. A value of XmAS_IS indicates that the
underline type is not specified for this rendition.
