Trait Implementations

impl SharedAppState for App

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

pub fn before_event(&mut self)

Before State::event is called, call this.

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

When DrawBaselayer::DefaultDraw is called, run this.

pub 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: &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 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

pub 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.

pub 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

pub fn draw_baselayer(&self) -> DrawBaselayer

Specifies what to draw before draw()

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

Before this state is popped or replaced, call this.
