[gtkmm] Propogate key press event

["I.S.Kuten" <i kuten sam-solutions net>]

Hello ,

I'm writing GTKmm + SDL app . 
SDL displayed in DrawingArea widget via GDK_WINDOW_XWINDOW

I defined my keypress callback :

bool MyApp::on_key_press_event(GdkEventKey* event)
   switch(event->keyval)
    {
        case GDK_Escape:
            m_button1.clicked();
            break;
........................ 

and want some key presses propagate further and go to DrawingArea widget , so that SDL  can hadle them .

How it can be done ?


Thanks,
