	42	\wxheading{Remarks}
	43
	44	When a sash belonging to a sash window is dragged by the user, and then released,
	45	this event is sent to the window, where it may be processed by an event table
	46	entry in a derived class, a plug-in event handler or an ancestor class.
	47
	48	Note that the wxSashWindow doesn't change the window's size itself. It relies on the application's
	49	event handler to do that. This is because the application may have to handle other consequences
	50	of the resize, or it may wish to veto it altogether. The event handler should
	51	look at the drag rectangle: see \helpref{wxSashEvent::GetDragRect}{wxsasheventgetdragrect} to see
	52	what the new size of the window would be if the resize were to be applied. It should
	53	also call \helpref{wxSashEvent::GetDragStatus}{wxsasheventgetdragstatus} to see whether the
	54	drag was OK or out of the current allowed range.

	77	\constfunc{wxRect}{GetDragRect}{\void}
	78
	79	Returns the rectangle representing the new size the window would be if the resize was applied. It is
	80	up to the application to set the window size if required.

	83
	84	\constfunc{wxSashDragStatus}{GetDragStatus}{\void}
	85
	86	Returns the status of the sash: one of wxSASH\_STATUS\_OK, wxSASH\_STATUS\_OUT\_OF\_RANGE.
	87	If the drag caused the notional bounding box of the window to flip over, for example, the drag will be out of rage.
