XtMakeGeometryRequest(3Xt) XT FUNCTIONSXtMakeGeometryRequest(3Xt)

NAME
       XtMakeGeometryRequest, XtMakeResizeRequest - make geometry
       manager request

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

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

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

       request	Specifies the desired widget geometry (size,
		 position, border 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 following:

       o    If the widget is unmanaged or the widget's parent is
	    not realized, it makes the changes and returns
	    XtGeometryYes.

       o    If the parent is not a subclass of compositeWidget-
	    Class or the parent's geometry_manager is NULL, it
	    issues an error.

       o    If the widget's being_destroyed field is True, it
	    returns XtGeometryNo.

       o    If the widget x, y, width, height and border_width
	    fields are all equal to the requested values, it
	    returns XtGeometryYes; otherwise, it calls the par-
	    ent's geometry_manager procedure with the given
	    parameters.

       o    If the parent's geometry manager returns

	    XtGeometryYes and if XtCWQueryOnly is not set in the
	    request_mode and if the widget is realized, XtMake-
	    GeometryRequest calls the XConfigureWindow Xlib func-
	    tion to reconfigure the widget's window (set its
	    size, location, and stacking order as appropriate).

       o    If the geometry manager returns XtGeometryDone, the
	    change has been approved and actually has been done.
	    In this case, XtMakeGeometryRequest does no configur-
	    ing 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,
       XtMakeGeometryRequest always returns XtGeometryYes when
       called by a child of a primitive widget.

       The XtMakeResizeRequest function, a simple interface to
       XtMakeGeometryRequest, creates a XtWidgetGeometry struc-
       ture 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
       XtGeometryAlmost, 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 XtGeometryAlmost
       replies, it can pass NULL for width_return and
       height_return.
