NAME [Toc] [Back]
XmStringDrawUnderline - A compound string function that underlines a
string drawn in an X Window
SYNOPSIS [Toc] [Back]
#include <Xm/Xm.h>
void XmStringDrawUnderline(
Display * d,
Window w,
XmRenderTable rendertable,
XmString string,
GC gc,
Position x,
Position y,
Dimension width,
unsigned char alignment,
unsigned char layout_direction,
XRectangle * clip,
XmString underline);
DESCRIPTION [Toc] [Back]
XmStringDrawUnderline draws a compound string in an X Window. If the
substring identified by underline can be matched in string, the
substring will be underlined. Once a match has occurred, no further
matches or underlining will be done. Only the first text component of
underline is used for matching.
If a compound string segment uses a rendition that contains a font
set, the graphic context passed to this routine will have the GC font
member left in an undefined state. The underlying XmbStringDraw
function called by this routine modifies the font ID field of the GC
passed into it and does not attempt to restore the font ID to the
incoming value. If the compound string segment is not drawn using a
font set, the graphic context must contain a valid font member.
Graphic contexts created by XtGetGC are not accepted by this routine;
instead, use XtAllocateGC to create a graphic context.
d Specifies the display.
w Specifies the window.
rendertable
Specifies the render table.
string Specifies the string.
gc Specifies the graphics context to use.
x Specifies a coordinate of the rectangle that will contain
the displayed compound string.

y Specifies a coordinate of the rectangle that will contain
the displayed compound string.
width Specifies the width of the rectangle that will contain the
displayed compound string.
alignment Specifies how the string will be aligned within the
specified rectangle. It is one of XmALIGNMENT_BEGINNING,
XmALIGNMENT_CENTER, or XmALIGNMENT_END.
layout_direction
Controls the direction in which the segments of the compound
string will be laid out. It also determines the meaning of
the alignment parameter.
clip Allows the application to restrict the area into which the
compound string will be drawn. If it is NULL, clipping will
be determined by the GC.
underline Specifies the substring to be underlined.
