NAME
XmRenderTableCopy -- A render table function that copies renditions SYNOPSIS
#include <Xm/Xm.h> XmRenderTable XmRenderTableCopy( XmRenderTable table, XmStringTag *tags, int tag_count); DESCRIPTION
XmRenderTableCopy creates a new render table which will contain the renditions of the table whose tags match those in tags. table Specifies the table containing the renditions to be copied. tags Specifies an array of tags, whose corresponding renditions are to be copied. NULL indicates that the complete table should be copied. tag_count Specifies the number of tags in tags. RETURN
Returns NULL if table is NULL. Otherwise, this function returns the new render table. This function allocates space to hold the new render table. The application is responsible for managing this allocated space. The application can recover this allocated space by calling XmRenderTableFree. RELATED

NAME
XmRenderTable -- Data type for a render table SYNOPSIS
#include <Xm/Xm.h> XmRenderTable DESCRIPTION
XmRenderTable is the data type for a render table, which contains a table of renditions (XmRenditions). Each rendition consists of a set of attributes for rendering text, including a font or fontset, colors, tabs, and lines. Each rendition is identified with a tag. When a compound string is displayed, for each segment in the string, the rendition used to render that string is formed as follows. If the segment has at least one rendition begin tag or if the list of tags formed by accumulating from previous segments the rendition begin tags and removing the rendition end tags is not empty, these tags are matched with renditions in the render table. The effective rendition used to render the segment is formed by successively merging each rendition found into the current rendition with non-XmAS_IS (XmUNSPECI- FIED_PIXEL for color resources) values for resources in the rendition to be merged, thus replacing the corresponding values of the resources in the current rendition. Finally, if the resulting rendition still has resources with unspecified values and the segment has a locale or charset tag (these are optional and mutually exclusive) this tag is matched with a rendition in the render table, and the missing rendition values are filled in from that entry. If no matching rendition is found for a particular tag, then the XmNnoRenditionCallback of the XmDisplay object is called and the render table is searched again for that tag. If the resulting rendition does not specify a font or fontset, then for segments whose text type is XmCHARSET_TEXT, the render table will be searched for a rendition tagged with XmFONTLIST_DEFAULT_TAG, and if a matching rendition is found, it will be merged into the current rendition. If the resulting rendition contains no font or fontset, the XmNnoFontCallback will be called with the default rendition and "" as the font name. If no rendition matches or no font was found after the callback, then the first rendition in the render table will be merged into the current rendition. If this rendition still has no font, then the segment will not be rendered and a warning will be emit- ted. For segments whose text type is XmMULTIBYTE_TEXT or XmWIDECHAR_TEXT, the render table will be searched for a rendition tagged with _MOTIF_DEFAULT_LOCALE, and, if a matching rendition is found, it will be merged into the current rendition. If the resulting rendition con- tains no font, the XmNnoFontCallback will be called with the default rendition and "" as the font name. An application can have this call- back attempt to remedy this problem by calling XmRenditionUpdate on the input rendition to provide a font for the widget to use. This may be done by either providing an alternative font name to be loaded using the XmNfontName and XmNfontType resources or with an already loaded font using the XmNfont resource. If no rendition matches or no font was found after the callback, then the segment will not be rendered and a warning will be issued. Render tables are specified in resource files with the following syntax: resource_spec: [ tag [, tag ]* ] where tag is some string suitable for the XmNtag resource of a rendition. If no tags are specified, then a render table will be created that is either empty or contains only a rendition with a tag of _MOTIF_DEFAULT_LOCALE. Specific values for specific rendition resources are specified using the following syntax: resource_spec [*|.] rendition[*|.] resource_name: value where: resource_spec Specifies the render table. rendition Is either the class Rendition or a tag. resource_name Is either the class or name of a particular resource. value Is the specification of the value to be set. Any resource line that consists of just a resource name or class component with no rendition component or loose binding will be assumed to specify resource values for a rendition with a tag of _MOTIF_DEFAULT_LOCALE. In effect, this creates a default rendition in much the same way that specifying no fontlist tag for a fontlist resource causes the fontlist created to contain an entry tagged with XmFONTLIST_DEFAULT_TAG: resource_spec.resource_name: value For example, the following would set the XmNrenderTable resource of label1 to a render table consisting of three renditions tagged with _MOTIF_DEFAULT_LOCALE, bold, and oblique, with values for resources set as described in the resource specifications. *label1.renderTable: bold, oblique *label1.renderTable.bold.renditionForeground: Green *label1.renderTable.bold.fontName: *-*-*-bold-*-iso8859-1 *label1.renderTable.bold.fontType: FONT_IS_FONT *label1.renderTable.oblique.renditionBackground: Red *label1.renderTable.oblique.fontName: *-*-*-italic-*-iso8859-1 *label1.renderTable.oblique.fontType: FONT_IS_FONT *label1.renderTable.oblique.underlineType: AS_IS *label1.renderTable.fontName: fixed *label1.renderTable.fontType: FONT_IS_FONT *label1.renderTable.renditionForegound: black *label1.renderTable*tabList: 1in, +1.5in, +3in RELATED
