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
                 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:

       ·    If the widget is unmanaged or the widget's parent is not realized,
            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
            XtGeometryNo.

       ·    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 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,
            location, and stacking order as appropriate).

       ·    If the geometry manager returns XtGeometryDone, the change has
            been approved and actually has been done.  In this case,
            XtMakeGeometryRequest 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,
       XtMakeGeometryRequest always returns XtGeometryYes when called by a
       child of a primitive widget.

       The XtMakeResizeRequest function, a simple interface to
       XtMakeGeometryRequest, 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
       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.
