How can I bind the ResizeRequest event?
The ResizeRequest event is used (typically by window managers) to interpose on configuration changes before they occur, possibly preventing them from occurring altogether and support for it was removed in Tk4. There is almost no imaginable case where Tk scripts should really be asking for ResizeRequest events; people tended to use them when what they really wanted was Configure events (which trigger after the resize has occured), and this produced very strange behavior in their programs. Try bind .widget
