NAME
XtGetGC, XtReleaseGC - obtain and destroy a sharable GC
SYNOPSIS
GC XtGetGC(w, value_mask, values)
Widget w;
XtGCMask value_mask;
XGCValues *values;
void XtReleaseGC(w, gc)
Widget w;
GC gc;
ARGUMENTS
Specifies the GC to be deallocated. Specifies the actual values for
this GC. Specifies which fields of the values are specified. Speci-
fies the widget.
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 wid-
get 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.
