Scrolled windows are used to create a scrollable area with another
widget inside it. You may insert any type of widget into a scrolled
window, and it will be accessible regardless of the size by using
the scrollbars.
GTK.ScrolledWindow(GTK.Adjustment(),GTK.Adjustment())->add(GTK.Label("A small label"))->set_usize(100,80)->set_policy(GTK.POLICY_AUTOMATIC,GTK.POLICY_AUTOMATIC)
GTK.ScrolledWindow(GTK.Adjustment(),GTK.Adjustment())->add(GTK.Label("A small label"))->set_usize(70,80)->set_policy(GTK.POLICY_AUTOMATIC,GTK.POLICY_AUTOMATIC)
GTK.ScrolledWindow(GTK.Adjustment(),GTK.Adjustment())->add(GTK.Label("A small label"))->set_usize(80,80)
GTK.ScrolledWindow(GTK.Adjustment(),GTK.Adjustment())->add(GTK.Label("A very huge label")->set_usize(700,700))->set_usize(80,80)
