# wxMouseCaptureChangedEvent(3erl)

Functions for wxMouseCaptureChangedEvent class

## NAME

wxMouseCaptureChangedEvent - Functions for wxMouseCaptureChangedEvent class

## DESCRIPTION

An mouse capture changed event is sent to a window that loses its mouse capture. This is called even if *wxWindow:releaseMouse/1* 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.

Only for:wxmsw

This class is derived (and can use functions) from: *wxEvent*
