Re: Tutorial for writing widgets in Gtk3

[Göran Hasse <gorhas raditex nu>]

If you look in the widget_class->draw section

MyButton *button = MY_BUTTON(widget);

Why is this pointer to button created? It is not used!

And where is the cairo_t *cr comming from?

This is a turorial that is not so easy to understand...
