<description><p>A sash event is sent when the sash of a <seeerl marker="wxSashWindow"><c>wxSashWindow</c></seeerl> has been dragged by the user.
      </p><p>Remark: When a sash belonging to a sash window is dragged by the user, and then released, this event is sent to the window, where it may be processed by an event table entry in a derived class, a plug-in event handler or an ancestor class. Note that the <seeerl marker="wxSashWindow"><c>wxSashWindow</c></seeerl> doesn't change the window's size itself. It relies on the application's event handler to do that. This is because the application may have to handle other consequences of the resize, or it may wish to veto it altogether. The event handler should look at the drag rectangle: see <seemfa marker="#getDragRect/1"><c>getDragRect/1</c></seemfa> to see what the new size of the window would be if the resize were to be applied. It should also call <seemfa marker="#getDragStatus/1"><c>getDragStatus/1</c></seemfa> to see whether the drag was OK or out of the current allowed range.
