signal_damage_event and connect.

["Anibal F. Martinez Cortina" <linuxkid zeuz gmail com>]

What seems to be wrong with this?

signal_damage_event().connect(sigc::mem_fun(&Dock::dibujarDock));

Entire code:

Dock::Dock() : Gtk::Window()

{

set_decorated(false);

set_default_size(200,200);

set_app_paintable(true);

contenedor = Gtk::manage(new Gtk::Box(Gtk::ORIENTATION_HORIZONTAL,0));

add(*contenedor);

botonPrueba = Gtk::manage(new Gtk::Button("Gran boton"));

contenedor->pack_start(*botonPrueba,Gtk::PACK_SHRINK);

contenedor->show_all();

signal_damage_event().connect(sigc::mem_fun(*this,&Dock::dibujarDock));

}

void Dock::dibujarDock()

{

contextoVentana = get_window()->create_cairo_context();

contextoVentana->set_source_rgba(1.0,1.0,1.0,0.0);

contextoVentana->set_operator(Cairo::OPERATOR_SOURCE);

contextoVentana->paint();

//contextoVentana->destroy();

}

It won't build even though it should be correct right?
