NAME
       XtMakeGeometryRequest, XtMakeResizeRequest - make geometry manager
       request

SYNTAX
       XtGeometryResult XtMakeGeometryRequest(Widget w, XtWidgetGeometry
	      *request, XtWidgetGeometry *reply_return);

       XtGeometryResult XtMakeResizeRequest(Widget w, Dimension width,
	      height, Dimension *width_return, Dimension *height_return);

ARGUMENTS
       reply_return
		 Returns the allowed widget size or may be NULL if the
		 requesting widget is not interested in handling XtGeome-
		 tryAlmost.

       request	 Specifies the desired widget geometry (size, position, bor-
		 der width, and stacking order).

       w	 Specifies the widget that is making the request.

       width_return
       height_return
		 Return the allowed widget width and height.

DESCRIPTION
       Depending on the condition, XtMakeGeometryRequest performs the follow-
       ing:

       ·    If the widget is unmanaged or the widget’s parent is not real-
	    ized, it makes the changes and returns XtGeometryYes.

       ·    If the parent is not a subclass of compositeWidgetClass or the
	    parent’s geometry_manager is NULL, it issues an error.

       ·    If the widget’s being_destroyed field is True, it returns XtGeom-
	    etryNo.

       ·    If the widget x, y, width, height and border_width fields are all
	    equal to the requested values, it returns XtGeometryYes; other-
	    wise, it calls the parent’s geometry_manager procedure with the
	    given parameters.

       ·    If the parent’s geometry manager returns XtGeometryYes and if
	    XtCWQueryOnly is not set in the request_mode and if the widget is
	    realized, XtMakeGeometryRequest calls the XConfigureWindow Xlib
	    function to reconfigure the widget’s window (set its size, loca-
	    tion, and stacking order as appropriate).

       ·    If the geometry manager returns XtGeometryDone, the change has
	    been approved and actually has been done.  In this case, XtMake-
	    GeometryRequest does no configuring and returns XtGeometryYes.
	    XtMakeGeometryRequest never returns XtGeometryDone.

       Otherwise, XtMakeGeometryRequest returns the resulting value from the
       parent’s geometry manager.

       Children of primitive widgets are always unmanaged; thus, XtMake-
       GeometryRequest always returns XtGeometryYes when called by a child of
       a primitive widget.

       The XtMakeResizeRequest function, a simple interface to XtMake-
       GeometryRequest, creates a XtWidgetGeometry structure and specifies
       that width and height should change.  The geometry manager is free to
       modify any of the other window attributes (position or stacking order)
       to satisfy the resize request.  If the return value is XtGeometryAl-
       most, width_return and height_return contain a compromise width and
       height.	If these are acceptable, the widget should immediately make
       an XtMakeResizeRequest and request that the compromise width and
       height be applied.  If the widget is not interested in XtGeometryAl-
       most replies, it can pass NULL for width_return and height_return.
