Class WpViewporterProxy

java.lang.Object

org.freedesktop.wayland.client.Proxy<WpViewporterEvents>

org.freedesktop.wayland.client.WpViewporterProxy

All Implemented Interfaces:

WaylandObject

public class WpViewporterProxy
extends Proxy<WpViewporterEvents>

surface cropping and scaling

The global interface exposing surface cropping and scaling capabilities is used to instantiate an interface extension for a wl_surface object. This extended interface will then allow cropping and scaling the surface contents, effectively disconnecting the direct relationship between the buffer and the surface size.

Method Details

destroy

public void destroy()

unbind from the cropping and scaling interface

Informs the server that the client will not be using this protocol object anymore. This does not affect any other objects, wp_viewport objects included.

Overrides:

destroy in class Proxy<WpViewporterEvents>

getViewport

public WpViewportProxy getViewport(WpViewportEvents implementation,
 @Nonnull
 WlSurfaceProxy surface)

extend surface interface for crop and scale

Instantiate an interface extension for the given wl_surface to crop and scale its content. If the given wl_surface already has a wp_viewport object associated, the viewport_exists protocol error is raised.

Parameters:

implementation - A protocol event listener for the newly created proxy.

surface - the surface
