[SOLVED] C++ can't connect mouse event to Gtk::DrawingArea

[xlinuks]

Hi, can someone please write a working snippet so that when clicking on a Gtk::DrawingArea it prints "clicked"?
I tried binding signal handlers but couldn't. It compiles fine but doesn't work.
I have


class PaintArea : public DrawingArea {...}

Then inside the constructor I write:


signal_button_press_event().connect( sigc::mem_fun( *this, &PaintArea::onMouseDown ) );


The onMouseDown method is:


bool PaintArea::onMouseDown( GdkEventButton *event ) {
cout << "clicked" << endl;
return true;
}


But I never get to see the "clicked" line printed.
On the other hand the on_expose_event works fine, but unfortunately I not only need to do custom painting but also track the mouse events.

Turns out windows don't accept mouse events unless one first enables support for mouse events one is interested in, like this:


pWindow->add_events( Gdk::BUTTON_PRESS_MASK | Gdk::BUTTON_RELEASE_MASK );
