}Expand description
Many states fit a pattern of managing a single panel, handling mouseover events, and other
interactions on the map. Implementing this instead of State reduces some boilerplate.
Required Methods§
Provided Methods§
Sourcefn on_click_custom(
&mut self,
_ctx: &mut EventCtx<'_>,
_app: &mut A,
_action: Box<dyn CloneableAny>,
_panel: &mut Panel,
) -> Transition<A>
fn on_click_custom( &mut self, _ctx: &mut EventCtx<'_>, _app: &mut A, _action: Box<dyn CloneableAny>, _panel: &mut Panel, ) -> Transition<A>
Called when something on the panel has been clicked.
Sourcefn panel_changed(
&mut self,
_: &mut EventCtx<'_>,
_: &mut A,
_: &mut Panel,
) -> Option<Transition<A>>
fn panel_changed( &mut self, _: &mut EventCtx<'_>, _: &mut A, _: &mut Panel, ) -> Option<Transition<A>>
Called when something on the panel has changed. If a transition is returned, stop handling the event and immediately apply the transition.
Sourcefn on_mouseover(&mut self, _: &mut EventCtx<'_>, _: &mut A)
fn on_mouseover(&mut self, _: &mut EventCtx<'_>, _: &mut A)
Called when the mouse has moved.
Sourcefn other_event(&mut self, _: &mut EventCtx<'_>, _: &mut A) -> Transition<A>
fn other_event(&mut self, _: &mut EventCtx<'_>, _: &mut A) -> Transition<A>
If a panel on_click event didn’t occur and panel_changed didn’t return transition, then
call this to handle all other events.
