NAME
XtGetGC, XtReleaseGC - obtain and destroy a sharable GC
SYNTAX
-
- GC XtGetGC(Widget w, XtGCMask value_mask, XGCValues
*values);
-
- void XtReleaseGC(Widget w, GC gc);
ARGUMENTS

DESCRIPTION
The
XtGetGC
function returns a sharable, read-only GC.
The parameters to this function are the same as those for
XCreateGC
except that a widget is passed instead of a display.
XtGetGC
shares only GCs in which all values in the GC returned by
XCreateGC
are the same.
In particular, it does not use the value_mask provided to
determine which fields of the GC a widget considers relevant.
The value_mask is used only to tell the server which fields should be
filled in with widget data and which it should fill in with default values.
For further information about value_mask and values,
see
XCreateGC
in the Xlib - C Language X Interface.
The
XtReleaseGC
function deallocate the specified shared GC.
