  Create a new Cairo surface that is as compatible as possible with the given this.
• public VulkanContext create_vulkan_context () throws Error
  Creates a new `GdkVulkanContext` for rendering on this.
• public void destroy ()
  Destroys the window system resources associated with this and decrements this's reference count.
• public unowned Cursor? get_cursor ()

• public unowned Cursor? get_device_cursor (Device device)
  Retrieves a `GdkCursor` pointer for the device currently set on the specified `GdkSurface`.
• public bool get_device_position (Device device, out double x, out double y, out ModifierType mask)
  Obtains the current device position and modifier state.
• public unowned Display get_display ()
  Gets the `GdkDisplay` associated with a `GdkSurface`.
• public unowned FrameClock get_frame_clock ()
  Gets the frame clock for the surface.
• public int get_height ()
  Returns the height of the given this.
• public bool get_mapped ()
  Checks whether the surface has been mapped.
• public int get_scale_factor ()
  Returns the internal scale factor that maps from surface coordinates to the actual device pixels.
• public int get_width ()
  Returns the width of the given this.
• public void hide ()
  Hide the surface.
• public bool is_destroyed ()
  Check to see if a surface is destroyed.
• public void queue_render ()
  Forces a [signal@Gdk.
• public void request_layout ()
  Request a layout phase from the surface's frame clock.
• public void set_cursor (Cursor? cursor)
  Sets the default mouse pointer for a `GdkSurface`.
• public void set_device_cursor (Device device, Cursor cursor)
  Sets a specific `GdkCursor` for a given device when it gets inside this.
• public void set_input_region (Region region)
  Apply the region to the surface for the purpose of event handling.
• public void set_opaque_region (Region? region)
  Marks a region of the `GdkSurface` as opaque.
• public bool translate_coordinates (Surface to, ref double x, ref double y)
  Translates coordinates between two surfaces.

Signals:

• public signal void enter_monitor (Monitor monitor)
  Emitted when surface starts being present on the monitor.
• public signal bool event (Event event)
  Emitted when GDK receives an input event for surface.
• public signal void layout (int width, int height)
  Emitted when the size of surface is changed, or when relayout should be performed.
• public signal void leave_monitor (Monitor monitor)
  Emitted when surface stops being present on the monitor.
• public signal bool render (Region region)
  Emitted when part of the surface needs to be redrawn.
