Trait conrod::backend::event::ToRawEvent [−] [src]

pub trait ToRawEvent {
    fn to_raw_event(self, win_w: Scalar, win_h: Scalar) -> Option<RawEvent>;
}

Types that may be converted to the RawEvent type used by conrod to track events happening in the world.

This is only used by conrod as a bound for the Ui::handle_event method.

Required Methods

fn to_raw_event(self, win_w: Scalar, win_h: Scalar) -> Option<RawEvent>

Convert self into an RawEvent.

Note: RawEvents that contain co-ordinates must be oriented with (0, 0) at the middle of the window with the y axis pointing upwards (Cartesian co-ordinates). Many windows provide coordinates with the origin in the top left with y pointing down, so you might need to translate these co-ordinates when implementing this method. Also be sure to invert the y axis of MouseScroll events.

The window dimensions are provided in case co-ordinates require translation.
