Every widget now has a GUI::FocusPolicy that determines how it can receive focus: - NoFocus: The widget is not focusable (default) - TabFocus: The widget can be focused using the tab key. - ClickFocus: The widget can be focused by clicking on it. - StrongFocus: Both of the above. For widgets that have a focus proxy, getting/setting the focus policy will affect the proxy instead.
