Hi there,

I had problems with TrayIcon programs under Windows during Shutdown when I did not have a TopWindow.

Solution was to add WM_QUERYENDSESSION listerner to TaryIcons derived class WindowProc.

I had two solution either to subclass (a) or add to TrayIcon::WindowProc (b)

LRESULT TrayIconDerived::WindowProc( UINT message, WPARAM wParam, LPARAM lParam ) {
	if ( message == WM_QUERYENDSESSION ) {
		ShutDown();
		return true;
	}
	return TrayIcon::WindowProc(message, wParam, lParam);
}

For both I needed to change repository code:
Could we either
a) have the TrayIcon::WindowProc make "protected" in header for subclassing or
b) add the handler to the TrayIcon::WindowProc itself?

Thanx for a thought!
Ralph
