@TCH:
Viszont, meg tudnád mutatni, hogy hogy néz ki Pythonban és C++-ban a következő cucc?

#include <gtkmm.h>

using namespace std;
using namespace Gtk;
using namespace Glib;

Window* window;
Button* button;
Entry*  entry;

void on_button_clicked() {
	entry->set_text("kecske");
}

	Main app(argc, argv);
	RefPtr<Builder> builder = Builder::create_from_file("kecske.glade");

	builder->get_widget("window", window);
	builder->get_widget("entry", entry);
	builder->get_widget("button", button);

	button->signal_clicked().connect(sigc::ptr_fun(on_button_clicked));

	app.run(*window);

	return 0;
}
