impl WidgetImpl for DeferDraw

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, _: &mut EventCtx, _: &mut WidgetOutput)

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

fn draw(&self, _: &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 Composite 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: &Box<dyn WidgetImpl>)

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