XtGetGC, XtReleaseGC - obtain and destroy
a sharable GC
- GC XtGetGC(Widget w, XtGCMask value_mask, XGCValues
- *values);
- void XtReleaseGC(Widget w, GC gc);
Specifies the GC
to be deallocated.
Specifies the actual values for this GC.
Specifies which
m.
Specifies the widget.
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.
