XtMakeGeometryRequest(3Xt)    SDK X11 R4.11MU05   XtMakeGeometryRequest(3Xt)


NAME
       XtMakeGeometryRequest, XtMakeResizeRequest - make geometry manager
       request

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

       XtGeometryResult XtMakeResizeRequest(w, width, height, widthreturn,
       heightreturn)
             Widget w;
             Dimension width, height;
             Dimension *widthreturn, *heightreturn

ARGUMENTS
       replyreturn
                 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.

       widthreturn
       heightreturn
                 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.
