A generic GDK event.
Implementations
sourceimpl Event
impl Event
pub fn get() -> Option<Event>
pub fn put(&self)
sourcepub fn set_handler<F: Fn(&mut Event) + 'static>(handler: Option<F>)
pub fn set_handler<F: Fn(&mut Event) + 'static>(handler: Option<F>)
Set the event handler.
The callback handler
is called for each event. If None
, event
handling is disabled.

sourcepub fn event_type(&self) -> EventType
pub fn event_type(&self) -> EventType
Returns the event type.
sourcepub fn is_send_event(&self) -> bool
pub fn is_send_event(&self) -> bool
Returns whether the event was sent explicitly.
sourcepub fn downcast<T: FromEvent>(self) -> Result<T, Self>
pub fn downcast<T: FromEvent>(self) -> Result<T, Self>
Tries to downcast to a specific event type.
sourcepub fn downcast_ref<T: FromEvent>(&self) -> Option<&T>
pub fn downcast_ref<T: FromEvent>(&self) -> Option<&T>
Tries to downcast to a specific event type.
sourcepub fn downcast_mut<T: FromEvent>(&mut self) -> Option<&mut T>
pub fn downcast_mut<T: FromEvent>(&mut self) -> Option<&mut T>
Tries to downcast to a specific event type.
