XtGetGC(Xt)       X Version 11 (Release 5) 6 January 1993        XtGetGC(Xt)


 Name

    XtGetGC - 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.

    valuemask
              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 valuemask provided to determine which fields of the GC a widget
    considers relevant.  The valuemask 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 valuemask and
    values, see XCreateGC(XS) in the Xlib - C Language X Interface.

    The XtReleaseGC function deallocates the specified shared GC.
