h1(#wxsashevent). Wx::SashEvent

A sash event is sent when the sash of a "SashWindow":sashwindow.html has been
dragged by the user.

h2. Derived from

"CommandEvent":commandevent.html

h2. Event table macros

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


|*evt_sash_dragged(id) { | event | ... }*|Process a EVT_SASH_DRAGGED event,when the user has finished dragging a sash.|
|*EVT_SASH_DRAGGED_RANGE(id1, id2, func)*|Process a EVT_SASH_DRAGGED_RANGE event,when the user has finished dragging a sash. The event handler is called when windows with ids in thegiven range have their sashes dragged.|

 enum SashDragStatus
 {
     SASH_STATUS_OK,
     SASH_STATUS_OUT_OF_RANGE
 };
 


h2. Remarks

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 SashWindow 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 "SashEvent#get_drag_rect":sashevent.html#SashEvent_getdragrect to see
what the new size of the window would be if the resize were to be applied. It should
also call "SashEvent#get_drag_status":sashevent.html#SashEvent_getdragstatus to see whether the
drag was OK or out of the current allowed range.

h3(#SashEvent_new). SashEvent.new

  *SashEvent.new*(%(arg-type)Integer% id = 0,  %(arg-type)"SashEdgePosition":sashedgeposition.html% edge = SASH_NONE)

Constructor.

h3(#SashEvent_getedge). SashEvent#get_edge

 "SashEdgePosition":sashedgeposition.html *get_edge*()

Returns the dragged edge. The return value is one of SASH_TOP, SASH_RIGHT, SASH_BOTTOM, SASH_LEFT.

h3(#SashEvent_getdragrect). SashEvent#get_drag_rect

 "Rect":rect.html *get_drag_rect*()

Returns the rectangle representing the new size the window would be if the resize was applied. It is
up to the application to set the window size if required.

h3(#SashEvent_getdragstatus). SashEvent#get_drag_status

 "SashDragStatus":sashdragstatus.html *get_drag_status*()

Returns the status of the sash: one of SASH_STATUS_OK, SASH_STATUS_OUT_OF_RANGE.
If the drag caused the notional bounding box of the window to flip over, for example, the drag will be out of rage.
