impl WidgetImpl for JustDraw
source§fn get_dims(&self) -> ScreenDims
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
.source§fn set_pos(&mut self, top_left: ScreenPt)
fn set_pos(&mut self, top_left: ScreenPt)
Your widget’s top left corner should be here. Handle mouse events and draw appropriately.
source§fn event(&mut self, _: &mut EventCtx<'_>, _: &mut WidgetOutput)
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.
source§fn draw(&self, g: &mut GfxCtx<'_>)
fn draw(&self, g: &mut GfxCtx<'_>)
Draw the widget. Be sure to draw relative to the top-left specified by
set_pos
.source§fn can_restore(&self) -> bool
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.
source§fn restore(&mut self, _: &mut EventCtx<'_>, _prev: &dyn WidgetImpl)
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.
