Maybe, but this is not the behavior when working straight from the GTK
label = gtk_label_new("foo");
gtk_widget_size_request (label, &requisition);
g_print ("Requisition is: %dx%d",
This returns a valid width and height. It doesn't make sense that you'd
have to pack/display/realize a widget before you get its size because if
you are implementing a new container, you need to know the size of the
widget before you can lay it out.
