pub fn handle_event( &mut self, widget_id: i32, event: CallbackEvent, ) -> Option<CallbackEvent>

Handles a specific event generated by the OS or the GUI interaction.

source

pub fn inject_event(&mut self, event: CallbackEvent)

Injects an event to all widgets, allowing them to exhibit custom event handling behavior if required. This is usually used in cases where special triggering needs to take place, like an indication of a timeout or transient error.
