   1 \section{\class{wxMouseCaptureChangedEvent}}\label{wxmousecapturechangedevent}
   2
   3 An mouse capture changed event is sent to a window that loses its
   4 mouse capture. This is called even if wxWindow::ReleaseCapture
   5 was called by the application code. Handling this event allows
   6 an application to cater for unexpected capture releases which
   7 might otherwise confuse mouse handling code.
   8
   9 This event is implemented under Windows only.

  54
  55 An mouse capture lost event is sent to a window that obtained mouse capture,
  56 which was subsequently loss due to "external" event, for example when a dialog
  57 box is shown or if another application captures the mouse.
  58
  59 If this happens, this event is sent to all windows that are on capture stack
  60 (i.e. called CaptureMouse, but didn't call ReleaseMouse yet). The event is
  61 {\em not} sent if the capture changes because of a call to CaptureMouse or
  62 ReleaseMouse.
  63
  64 This event is currently emitted under Windows only.
