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
- 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.
