Trait kas::WidgetConfig

Widget configuration

This trait is part of the Widget family and is derived by derive(Widget) unless #[widget(config = noauto)] is used. key_nav and cursor_icon may be customised without a manual implementation (e.g. #[widget(config(key_nav = true))]).

This trait allows some configuration of widget behaviour. All methods have default implementations. Most frequently, this trait is used to implement some custom action during configure: WidgetConfig::configure.

Provided methods

fn configure(&mut self, _: &mut Manager)

Configure widget

Widgets are configured on window creation and when TkAction::Reconfigure is sent.

Configure is called before resizing (but after calculation of the initial window size). This method is called after a WidgetId has been assigned to self, and after configure has been called on each child.

The default implementation of this method does nothing.

fn configure_recurse<'a, 'b>(&mut self, cmgr: ConfigureManager<'a, 'b>)

Configure self and children

In most cases one should not override the default implementation of this method but instead use WidgetConfig::configure; the exception is widgets with pop-ups.

fn key_nav(&self) -> bool

Is this widget navigable via Tab key?

Defaults to false.

fn cursor_icon(&self) -> CursorIcon

Which cursor icon should be used on hover?

Defaults to event::CursorIcon::Default.
