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.
