\section{\class{wxMouseCaptureChangedEvent}}\label{wxmousecapturechangedevent}

An mouse capture changed event is sent to a window that loses its
mouse capture. This is called even if wxWindow::ReleaseCapture
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.

This event is implemented under Windows only.

To process this event, use the following event handler macro to direct input to a member
function that takes a wxMouseCaptureChangedEvent argument.

Constructor.

\constfunc{wxWindow*}{GetCapturedWindow}{\void}

Returns the window that gained the capture, or NULL if it was a non-wxWidgets window.


\section{\class{wxMouseCaptureLostEvent}}\label{wxmousecapturelostevent}

An mouse capture lost event is sent to a window that obtained mouse capture,
which was subsequently loss due to "external" event, for example when a dialog
box is shown or if another application captures the mouse.

If this happens, this event is sent to all windows that are on capture stack
(i.e. called CaptureMouse, but didn't call ReleaseMouse yet). The event is
{\em not} sent if the capture changes because of a call to CaptureMouse or
ReleaseMouse.

This event is currently emitted under Windows only.
