Window.this
this
()Creates a new [gtk.window.Window].
To get an undecorated window (no window borders), use [gtk.window.Window.setDecorated].
All top-level windows created by [gtk.window.Window.new_] are stored in an internal top-level window list. This list can be obtained from [gtk.window.Window.listToplevels]. Due to GTK keeping a reference to the window internally, [gtk.window.Window.new_] does not return a reference to the caller.
To delete a [gtk.window.Window], call [gtk.window.Window.destroy].
Returns
a new [gtk.window.Window].
