NAME

       XtMakeGeometryRequest, XtMakeResizeRequest - make geometry manager request

SYNTAX

       #include <X11/Intrinsic.h>

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

       XtGeometryResult XtMakeResizeRequest(Widget w, Dimension width, Dimension 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.
