Receiving button press events

[Philipp Klaus Krause <pkk spth de>]

I want to receive button press evvents from a widget, so far it doesn't
work though.

in main.c:

Gtk::Image *paint_tileset = 0;
refXml->get_widget("paint_tileset", paint_tileset);
paint_tileset->add_events(Gdk::BUTTON_PRESS_MASK);
paint_tileset->signal_button_press_event().connect(sigc::mem_fun(display,
&Display::set_paint_tile));
kit.run(*main_win);

in display.cc:

bool Display::set_paint_tile(GdkEventButton *ev)
{
std::cout << "Tile chosen";
std::cout.flush();
return(true);
}

However Display::set_paint_tile() is not called when I click on
paint_tileset.
