XtGetGC(3Xt)
X11R6
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
  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.
