Struct map_gui::simple_app::SimpleApp

pub struct SimpleApp<T> {
    pub map: Map,
    pub draw_map: DrawMap,
    pub cs: ColorScheme,
    pub opts: Options,
    pub current_selection: Option<ID>,
    pub session: T,
    pub time: Time,
}

Simple app state that just renders a static map, without any dynamic agents on the map.

Fields

map: Map

draw_map: DrawMap

cs: ColorScheme

opts: Options

current_selection: Option<ID>

session: T

Custom per-app state can be stored here

time: Time

If desired, this can be advanced to render traffic signals changing.

Implementations

impl<T: 'static> SimpleApp<T>

pub fn new<F: 'static + Fn(&mut EventCtx<'_>, &mut SimpleApp<T>) -> Vec<Box<dyn State<SimpleApp<T>>>>>(
    ctx: &mut EventCtx<'_>,
    opts: Options,
    session: T,
    init_states: F
) -> (SimpleApp<T>, Vec<Box<dyn State<SimpleApp<T>>>>)

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

pub fn draw_zoomed(&self, g: &mut GfxCtx<'_>, opts: DrawOptions)

pub fn recalculate_current_selection(&mut self, ctx: &EventCtx<'_>)

Assumes some defaults.

pub fn mouseover_unzoomed_roads_and_intersections(
    &self,
    ctx: &EventCtx<'_>
) -> Option<ID>

pub fn mouseover_unzoomed_buildings(&self, ctx: &EventCtx<'_>) -> Option<ID>

Only select buildings, and work whether zoomed in or not.

fn calculate_current_selection(
    &self,
    ctx: &EventCtx<'_>,
    unzoomed_roads_and_intersections: bool,
    unzoomed_buildings: bool
) -> Option<ID>

fn change_color_scheme(

impl<T: 'static> SharedAppState for SimpleApp<T>

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 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.

pub fn before_event(&mut self)

Before State::event is called, call this.

impl<T> State<SimpleApp<T>> for SimpleWarper

fn event(
    &mut self,
    ctx: &mut EventCtx<'_>,
    _: &mut SimpleApp<T>
) -> Transition<SimpleApp<T>>

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

fn draw(&self, _: &mut GfxCtx<'_>, _: &SimpleApp<T>)

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.
