4dragged by the user.

22To process an activate event, use these event handler macros to direct input to a member
23function that takes a wxSashEvent argument.

46\wxheading{Remarks}
47
48When a sash belonging to a sash window is dragged by the user, and then released,
49this event is sent to the window, where it may be processed by an event table
50entry in a derived class, a plug-in event handler or an ancestor class.
51
52Note that the wxSashWindow doesn't change the window's size itself. It relies on the application's
53event handler to do that. This is because the application may have to handle other consequences
54of the resize, or it may wish to veto it altogether. The event handler should
55look at the drag rectangle: see \helpref{wxSashEvent::GetDragRect}{wxsasheventgetdragrect} to see
56what the new size of the window would be if the resize were to be applied. It should
57also call \helpref{wxSashEvent::GetDragStatus}{wxsasheventgetdragstatus} to see whether the
58drag was OK or out of the current allowed range.

77Returns the dragged edge. The return value is one of wxSASH\_TOP, wxSASH\_RIGHT, wxSASH\_BOTTOM, wxSASH\_LEFT.

79\membersection{wxSashEvent::GetDragRect}\label{wxsasheventgetdragrect}
80
81\constfunc{wxRect}{GetDragRect}{\void}
82
83Returns the rectangle representing the new size the window would be if the resize was applied. It is
84up to the application to set the window size if required.
85
86\membersection{wxSashEvent::GetDragStatus}\label{wxsasheventgetdragstatus}
87
88\constfunc{wxSashDragStatus}{GetDragStatus}{\void}
89
90Returns the status of the sash: one of wxSASH\_STATUS\_OK, wxSASH\_STATUS\_OUT\_OF\_RANGE.
91If the drag caused the notional bounding box of the window to flip over, for example, the drag will be out of rage.
