Implementations

impl DrawWithTooltips

pub fn new_widget( ctx: &EventCtx<'_>, batch: GeomBatch, tooltips: Vec<(Polygon, Text, Option<ClickOutcome>)>, hover: Box<dyn Fn(&Polygon) -> GeomBatch> ) -> Widget

batch: the GeomBatch to draw tooltips: (hitbox, text, clickable action) tuples where each text is shown when the user hovers over the respective hitbox. If an action is present and the user clicks the hitbox, then it acts like a button click. It’s assumed the hitboxes are non-overlapping. hover: returns a GeomBatch to render upon hovering. Return an GeomBox::new() if you want hovering to be a no-op

Trait Implementations

impl WidgetImpl for DrawWithTooltips

fn get_dims(&self) -> ScreenDims

What width and height does the widget occupy? If this changes, be sure to set redo_layout to true in event.

fn set_pos(&mut self, top_left: ScreenPt)

Your widget’s top left corner should be here. Handle mouse events and draw appropriately.

fn event(&mut self, ctx: &mut EventCtx<'_>, output: &mut WidgetOutput)

Your chance to react to an event. Any side effects outside of this widget are communicated through the output.

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

Draw the widget. Be sure to draw relative to the top-left specified by set_pos.

fn can_restore(&self) -> bool

If a new Panel is being created to replace an older one, all widgets have the chance to preserve state from the previous version.

fn restore(&mut self, _: &mut EventCtx<'_>, _prev: &dyn WidgetImpl)

Restore state from the previous version of this widget, with the same ID. Implementors must downcast.
