XmbDrawText(3X11) XmbDrawText(3X11) NAME XmbDrawText, XwcDrawText - draw text using multiple font sets SYNOPSIS void XmbDrawText(display, d, gc, x, y, items, nitems) Display *display; Drawable d; GC gc; int x, y; XmbTextItem *items; int nitems; void XwcDrawText(display, d, gc, x, y, items, nitems) Display *display; Drawable d; GC gc; int x, y; XwcTextItem *items; int nitems; ARGUMENTS Specifies the drawable. Specifies the connection to the X server. Specifies the GC. Specifies an array of text items. Specifies the number of text items in the array. Specify the x and y coordinates. DESCRIPTION The XmbDrawText and XwcDrawText functions allow complex spacing and font set shifts between text strings. Each text item is processed in turn, with the origin of a text element advanced in the primary draw direction by the escapement of the previous text item. A text item delta specifies an additional escapement of the text item drawing ori- gin in the primary draw direction. A font_set member other than None in an item causes the font set to be used for this and subsequent text items in the text_items list. Leading text items with a font_set member set to None will not be drawn. XmbDrawText and XwcDrawText do not perform any context-dependent ren- dering between text segments. Clients may compute the drawing metrics by passing each text segment to XmbTextExtents and XwcTextExtents or XmbTextPerCharExtents and XwcTextPerCharExtents. When the XFontSet has missing charsets, each unavailable character is drawn with the default string returned by XCreateFontSet. The behavior for an invalid code- point is undefined. STRUCTURES The XmbTextItem structure contains: typedef struct { char *chars; /* pointer to string */ int nchars; /* number of bytes */ int delta; /* pixel delta between strings */ XFontSet font_set; /* fonts, None means do not change */ } XmbTextItem; The XwcTextItem structure contains: typedef struct { wchar_t *chars; /* pointer to wide char string */ int nchars; /* number of wide characters */ int delta; /* pixel delta between strings */ XFontSet font_set; /* fonts, None means do not change */ } XwcTextItem; SEE ALSO XDrawImageString(3X11), XDrawString(3X11), XDrawText(3X11), XmbDrawIm- ageString(3X11), XmbDrawString(3X11) Xlib -- C Language X Interface XmbDrawText(3X11)
