class mrpt::gui::mrptEventWindowClosed
An event sent by a window upon when it’s about to be closed, either manually by the user or programmatically.
The event field member allow_close is default by default, but can be set to false in the event callback to forbid the window to be closed by the user. If the event corresponds to a programatic close, this field is ignored.
IMPORTANTE NOTICE: Event handlers in your observer class will be invoked from the wxWidgets internal MRPT thread, so all your code in the handler must be thread safe.
