Re: Re[2]: Exit when a signal is recieved

Do I need to write my own MainLoop?  I wouldn't like this. In my case the 
solution could be to use wxIdleEvent to call ExitMainLoop(). 

void OnSignal( int sig )
{
    GetMyApp()->mbSignal = true;
}

void MyApp::OnIdle( wxIdleEvent& event )
{
    if( mbSignal ) ExitMainLoop();
}
