XtGetGC(3Xt)                                         XtGetGC(3Xt)



NAME
     XtGetGC, XtReleaseGC - get and release 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;

DESCRIPTION
     The XtGetGC function returns a sharable, read-only graphics
     context (GC) structure.  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 provid-
     ed to determine which members of the GC a widget considers
     relevant.  The value-mask is used only to tell the server
     which members should be filled in with widget data and which
     it should fill in with default values.  For further informa-
     tion about value-mask and values, see XCreateGC in Xlib - C
     Language Interface.

     The XtReleaseGC function deallocates the specified shared
     GC.

   Arguments
     These functions accept the following arguments:

     gc      Specifies the GC to be deallocated.

     values  Specifies the actual values for this GC.

     value-mask
             Specifies the members for which values are speci-
             fied.

     w       Specifies the widget.
