## Detailed Description

An mouse capture changed event is sent to a window that loses its mouse capture.

This is called even if wxWindow::ReleaseMouse was called by the application code. Handling this event allows an application to cater for unexpected capture releases which might otherwise confuse mouse handling code.

Availability: only available for the wxMSW port.

## Events using this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxMouseCaptureChangedEvent& event)

Event macros:

- EVT_MOUSE_CAPTURE_CHANGED(func):
  Process a `wxEVT_MOUSE_CAPTURE_CHANGED` event.
