Required Methods

fn scale_factor_changed( &mut self, conn: &Connection, qh: &QueueHandle<Self>, surface: &WlSurface, new_factor: i32 )

The surface has either been moved into or out of an output and the output has a different scale factor.

fn transform_changed( &mut self, conn: &Connection, qh: &QueueHandle<Self>, surface: &WlSurface, new_transform: Transform )

The surface has either been moved into or out of an output and the output has different transform.

fn frame( &mut self, conn: &Connection, qh: &QueueHandle<Self>, surface: &WlSurface, time: u32 )

A frame callback has been completed.

Frame callbacks are used to avoid updating surfaces that are not currently visible. If a frame callback is requested prior to committing a surface, the client should avoid drawing to that surface until the callback completes. See the WlSurface::frame request for more details.

This function will be called if you request a frame callback by passing the surface itself as the userdata (surface.frame(&queue, &surface)); you can also implement Dispatch for other values to more easily dispatch rendering for specific surface types.
