Trait Implementations

impl SharedAppState for App

fn draw_default(&self, g: &mut GfxCtx<'_>)

When DrawBaselayer::DefaultDraw is called, run this.

fn dump_before_abort(&self, canvas: &Canvas)

Will be called if State::event or State::draw panics.

fn before_quit(&self, canvas: &Canvas)

Called before a normal exit, like window close

fn before_event(&mut self)

Before State::event is called, call this.

fn free_memory(&mut self)

If widgetry determines the video card is low on memory, this may be called. The application should make its best effort to delete any unused Drawables.

impl SimpleState<App> for EditRoad

fn on_click( &mut self, ctx: &mut EventCtx<'_>, app: &mut App, x: &str, panel: &mut Panel, ) -> Transition<App>

Called when something on the panel has been clicked. Since the action is just a string, the fallback case can just use unreachable!().

fn panel_changed( &mut self, ctx: &mut EventCtx<'_>, app: &mut App, panel: &mut Panel, ) -> Option<Transition<App>>

Called when something on the panel has changed. If a transition is returned, stop handling the event and immediately apply the transition.

fn other_event( &mut self, ctx: &mut EventCtx<'_>, _: &mut App, ) -> Transition<App>

If a panel on_click event didn’t occur and panel_changed didn’t return transition, then call this to handle all other events.

fn draw(&self, g: &mut GfxCtx<'_>, _: &App)

fn draw_baselayer(&self) -> DrawBaselayer

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.

fn on_mouseover(&mut self, _: &mut EventCtx<'_>, _: &mut A)

Called when the mouse has moved.

impl State<App> for MainState

fn event(&mut self, ctx: &mut EventCtx<'_>, app: &mut App) -> Transition<App>

Respond to a UI event, such as input or time passing.

fn draw(&self, g: &mut GfxCtx<'_>, app: &App)

Draw

fn draw_baselayer(&self) -> DrawBaselayer

Specifies what to draw before draw()

fn on_destroy(&mut self, _: &mut EventCtx<'_>, _: &mut A)

Before this state is popped or replaced, call this.

fn recreate(&mut self, _: &mut EventCtx<'_>, _: &mut A) -> Box<dyn State<A>>

Respond to Transition::Recreate by assuming state in the app has changed, but preserving the State-specific state appropriately.

impl State<App> for PickMap

fn event(&mut self, ctx: &mut EventCtx<'_>, app: &mut App) -> Transition<App>

Respond to a UI event, such as input or time passing.

fn draw(&self, g: &mut GfxCtx<'_>, _: &App)

Draw

fn draw_baselayer(&self) -> DrawBaselayer

Specifies what to draw before draw()

fn on_destroy(&mut self, _: &mut EventCtx<'_>, _: &mut A)

Before this state is popped or replaced, call this.

fn recreate(&mut self, _: &mut EventCtx<'_>, _: &mut A) -> Box<dyn State<A>>

Respond to Transition::Recreate by assuming state in the app has changed, but preserving the State-specific state appropriately.
