Function bind_event_handler

pub fn bind_event_handler<F>(
    handle: &ControlHandle,
    parent_handle: &ControlHandle,
    f: F,
) -> EventHandler
where
    F: Fn(Event, EventData, ControlHandle) + 'static,

Hook the window subclass with the default event dispatcher. The hook is applied to the control and its parent. All common controls send their events to their parent.

Arguments: - handle: Handle to the main control to hook - parent_handle: Parent to the main control. - f: User event callback

Returns a EventHandler that can be passed to unbind_event_handler to remove the callbacks.
