Detailed Description

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.

Member Function Documentation

◆ get_class()

std::string wayland::server::resource_t::get_class ( )
inherited

Retrieve the interface name (class) of a resource object.

Returns
Interface name of the resource object.

◆ get_client()

client_t wayland::server::resource_t::get_client ( ) const
inherited

Get the associated client

Returns
the client that owns the resource.

◆ get_id()

uint32_t wayland::server::resource_t::get_id ( ) const
inherited

Get the internal ID of the resource

Returns
the internal ID of the resource

◆ get_version()

unsigned int wayland::server::resource_t::get_version ( ) const
inherited

Get interface version

Returns
Interface version this resource has been constructed with.

◆ on_destroy()

std::function< void()> & viewporter_t::on_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.

Definition at line 796 of file wayland-server-protocol-extra.cpp.

◆ on_get_viewport()

std::function< void(viewport_t, surface_t)> & viewporter_t::on_get_viewport ( )

extend surface interface for crop and scale

Parameters
idthe new viewport interface id
surfacethe surface

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.

Definition at line 802 of file wayland-server-protocol-extra.cpp.

◆ post_no_memory()

void wayland::server::resource_t::post_no_memory ( ) const
inherited

Post "not enough memory" error to the client

If the compositor has not enough memory to fulfill a certail request of the client, this function can be called to notify the client of this circumstance.

◆ post_viewport_exists()

void viewporter_t::post_viewport_exists ( std::string const &  msg)

Post error: the surface already has a viewport object associated.

Definition at line 808 of file wayland-server-protocol-extra.cpp.

◆ proxy_has_object()

bool wayland::server::resource_t::proxy_has_object ( ) const
inherited

Check whether this wrapper actually wraps an object.

Returns
true if there is an underlying object, false if this wrapper is empty
