[gtkmm] Windowsize

[pfemat web de]

Hello list,

	I have an gtkmm application that packs one single widget into a window.
	The widget is derived from Gtk::DrawingArea and there is some 2d
	animation implemented. now the question might not be gtkmm-related: how is
	the windowsize calculated? I am curious since when i resize my
	window it shows 0 0 as vertical and horizontal size and when
	resizing it starts counting beyond my widget. The widget calls a

		set_size_request(320,200) 

	and this works fine.
