Detailed Description

interface for activating surfaces

A global interface used for informing the compositor about applications being activated or started, or for applications to request to be activated.

Definition at line 7515 of file wayland-server-protocol-unstable.hpp.

Member Function Documentation

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

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


Interface name of the resource object.

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

Get the associated client


the client that owns the resource.

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

Get the internal ID of the resource


the internal ID of the resource

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

Get interface version


Interface version this resource has been constructed with.

std::function< void(std::string, surface_t)> & xdg_activation_v1_t::on_activate ()

notify new interaction being available


token the activation token of the initiating client
surface the wl_surface to activate

Requests surface activation. It's up to the compositor to display this information as desired, for example by placing the surface above the rest.

The compositor may know who requested this by checking the activation token and might decide not to follow through with the activation if it's considered unwanted.

Compositors can ignore unknown presentation tokens when an invalid token is passed.

Definition at line 7435 of file wayland-server-protocol-unstable.cpp.

std::function< void()> & xdg_activation_v1_t::on_destroy ()

destroy the xdg_activation object Notify the compositor that the xdg_activation object will no longer be used.

The child objects created via this interface are unaffected and should be destroyed separately.

Definition at line 7423 of file wayland-server-protocol-unstable.cpp.

std::function< void(xdg_activation_token_v1_t)> & xdg_activation_v1_t::on_get_activation_token ()

requests a token



Creates an xdg_activation_token_v1 object that will provide the initiating client with a unique token for this activation. This token should be offered to the clients to be activated.

Definition at line 7429 of file wayland-server-protocol-unstable.cpp.

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.

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

Check whether this wrapper actually wraps an object.


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