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.

fn surface_enter( &mut self, conn: &Connection, qh: &QueueHandle<Self>, surface: &WlSurface, output: &WlOutput, )

The surface has entered an output.

fn surface_leave( &mut self, conn: &Connection, qh: &QueueHandle<Self>, surface: &WlSurface, output: &WlOutput, )

The surface has left an output.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
