Required Methods§
sourcefn set_focus(&self, focus: Option<&impl IsA<Widget>>)
fn set_focus(&self, focus: Option<&impl IsA<Widget>>)
If @focus is not the current focus widget, and is focusable, sets it as the focus widget for the root.
If @focus is None
, unsets the focus widget for the root.
To set the focus to a particular widget in the root, it is usually
more convenient to use WidgetExt::grab_focus()
instead of
this function.
focus
widget to be the new focus widget, or None
to unset the focus widget
