A compound string component identifies some part of a compound string, and can have a value and length\&. A compound string component can be one of the following types\&. These component types are grouped according to their length and value types\&. .PP The following components have values of NULL and lengths of 0 (zero)\&. .IP "\fBXmSTRING_COMPONENT_SEPARATOR\fP" 10 This component usually maps to a newline or carriage return in displayed text\&. .IP "\fBXmSTRING_COMPONENT_TAB\fP" 10 This component may be thought of as a text component containing only a single tab\&. .IP "\fBXmSTRING_COMPONENT_LAYOUT_POP\fP" 10 The layout direction is kept on a stack, with the current direction kept on top of the stack\&. When this component is read, the most recently read layout direction is popped off the stack and replaced by the direction immediately before it\&. .IP "\fBXmSTRING_COMPONENT_END\fP" 10 This component marks the end of a compound string\&. No other components should follow\&. If an application does not place an \fBXmSTRING_COMPONENT_END\fP component at the end of an \fBXmString\fR, Motif automatically does it for the application\&. .PP The following component has a value of \fBXmDirection\fR and the length of that direction\&. .IP "\fBXmSTRING_COMPONENT_LAYOUT_PUSH\fP" 10 The layout direction is kept on a stack, with the current direction kept on top of the stack\&. This component replaces the current layout direction, and causes another to be pushed onto the top of this stack\&. .PP The following component has a value of \fBXmStringDirection\fR and the length of that direction\&. .IP "\fBXmSTRING_COMPONENT_DIRECTION\fP" 10 This component sets the string direction by overriding the previous string direction\&. .PP The following components have values of type \fBchar *\fR or some equivalent type, and the lengths of these types\&. .IP "\fBXmSTRING_COMPONENT_LOCALE_TEXT\fP" 10 This component contains the multibyte text of a compound string\&. .IP "\fBXmSTRING_COMPONENT_WIDECHAR_TEXT\fP" 10 This component contains the widechar text of a compound string\&. .IP "\fBXmSTRING_COMPONENT_TEXT\fP" 10 This component contains the charset text of a compound string\&. Note that a compound string cannot contain both charset and locale (multibyte or widechar) text\&. .IP "\fBXmSTRING_COMPONENT_RENDITION_BEGIN\fP" 10 This component marks the beginning of a new rendition\&. All text following this component will be rendered using this rendition as the primary one\&. If there is already a rendition in effect, it is kept in memory and used to fill in any unspecified values in the primary rendition\&. Renditions are kept until a corresponding \fBXmSTRING_COMPONENT_RENDITION_END\fP component is encountered\&. .IP "\fBXmSTRING_COMPONENT_RENDITION_END\fP" 10 This component signifies that the specified rendition will no longer be used to render text, and will not be available to fill in unspecified values of newer renditions\&. .IP "\fBXmSTRING_COMPONENT_UNKNOWN\fP" 10 This component type signifies that the component contents belong to an unknown component type\&. .IP "\fBXmSTRING_COMPONENT_LOCALE\fP" 10 Use this component to specify the locale in which an internationalized application is to execute\&. The only valid character string for this component is \fB_MOTIF_DEFAULT_LOCALE\fP\&. .IP "\fBXmSTRING_COMPONENT_TAG\fP" 10 For charset text, this is the tag of the font to be used to display the text\&. This tag is sometimes referred to as the charset tag or the fontlist tag\&. .IP "\fBXmSTRING_COMPONENT_CHARSET\fP" 10 This component is obsolete and remains for compatibility with previous releases\&. It has been replaced by \fBXmSTRING_COMPONENT_TAG\fP\&. .IP "\fBXmSTRING_COMPONENT_FONTLIST_ELEMENT_TAG\fP" 10 This component is obsolete and remains for compatibility with previous releases\&. It has been replaced by \fBXmSTRING_COMPONENT_TAG\fP\&. .PP Some compound string components depend on values defined in other components\&. The \fBXmSTRING_COMPONENT_TAB\fP component definition, for example, depends on information in the \fBXmSTRING_COMPONENT_RENDITION_BEGIN\fP\&. To account for these dependencies, a typical compound string will have its member components in the following order: .PP .nf [ [ \fBXmSTRING_COMPONENT_LAYOUT_PUSH\fP ] [ \fBXmSTRING_COMPONENT_RENDITION_BEGIN\fP ]* [ \fBXmSTRING_COMPONENT_TAG\fP | \fBXmSTRING_COMPONENT_LOCALE\fP ] [ \fBXmSTRING_COMPONENT_TAB\fP ]* [ \fBXmSTRING_COMPONENT_DIRECTION\fP ] [ \fBXmSTRING_COMPONENT_TEXT\fP | \fBXmSTRING_COMPONENT_LOCALE_TEXT\fP | \fBXmSTRING_COMPONENT_WIDECHAR_TEXT\fP ] [ \fBXmSTRING_COMPONENT_RENDITION_END\fP ]* [ \fBXmSTRING_COMPONENT_LAYOUT_POP\fP ] [ \fBXmSTRING_COMPONENT_SEPARATOR\fP ] ]* \fBXmSTRING_COMPONENT_END\fP .fi ...\" created by instant / docbook-to-man, Sun 22 Dec 1996, 20:30
