Implementations

impl XSurface

fn current_buffer(&self) -> usize

Returns index of the current (on-screen) buffer, or 0 if there are no buffers.

fn draw_buffer(&mut self, buffer_index: usize)

Draws the indicated buffer onto the screen.

fn lazily_allocate_buffer(&mut self, buffer_index: usize) -> Option<&Buffer>

Gets the buffer at buffer_index, allocating it if necessary.

Trait Implementations

impl Drop for XSurface

fn drop(&mut self)

Executes the destructor for this type.

impl GpuDisplaySurface for XSurface

fn surface_descriptor(&self) -> u64

Returns an unique ID associated with the surface. This is typically generated by the compositor or cast of a raw pointer.

fn framebuffer(&mut self) -> Option<GpuDisplayFramebuffer<'_>>

Returns the next framebuffer, allocating if necessary.

fn next_buffer_in_use(&self) -> bool

Returns true if the next buffer in the swapchain is already in use.

fn close_requested(&self) -> bool

Returns true if the surface should be closed.

fn flip(&mut self)

Puts the next buffer on the screen, making it the current buffer.

fn buffer_completion_type(&self) -> u32

Returns the type of the completed buffer.

fn draw_current_buffer(&mut self)

Draws the current buffer on the screen.

fn on_client_message(&mut self, client_data: u64)

Handles a compositor-specific client event.

fn on_shm_completion(&mut self, shm_complete: u64)

Handles a compositor-specific shared memory completion event.

fn flip_to( &mut self, _import_id: u32, _acquire_timepoint: Option<SemaphoreTimepoint>, _release_timepoint: Option<SemaphoreTimepoint>, _extra_info: Option<FlipToExtraInfo> ) -> Result<Waitable>

Puts the specified import_id on the screen.

fn commit(&mut self) -> GpuDisplayResult<()>

Commits the surface to the compositor.

fn set_mouse_mode(&mut self, _mouse_mode: MouseMode)

Sets the mouse mode used on this surface.

fn set_position(&mut self, _x: u32, _y: u32)

Sets the position of the identified subsurface relative to its parent.
