Trait orbtk::prelude::EventHandler

pub trait EventHandler {
    fn handle_event(
        &self, 
        state_context: &mut StatesContext<'_>, 
        event: &EventBox
    ) -> bool;
    fn handles_event(&self, event: &EventBox) -> bool;
}

This trait is used to define an event handler.

Required methods

fn handle_event(
    &self,
    state_context: &mut StatesContext<'_>,
    event: &EventBox
) -> bool

Handles an event by the given widget. If it returns true the event will not be forwarded.

fn handles_event(&self, event: &EventBox) -> bool

Check if the handler could handle the given event box.
