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