The way for a client to pass focus to another toplevel is as follows. The client that intends to activate another toplevel uses the xdg_activation_v1.get_activation_token request to get an activation token. This token is then passed to the client to be activated through a separate band of communication. The client to be activated will then pass the token it received to the xdg_activation_v1.activate request. The compositor can then use this token to decide how to react to the activation request. The token the activating client gets may be ineffective either already at the time it receives it, for example if it was not focused, for focus stealing prevention. The activating client will have no way to discover the validity of the token, and may still forward it to the to be activated client. The created activation token may optionally get information attached to it that can be used by the compositor to identify the application that we intend to activate. This can for example be used to display a visual hint about what application is being started. Warning! The protocol described in this file is currently in the testing phase. Backward compatible changes may be added together with the corresponding interface version bump. Backward incompatible changes can only be done by creating a new major version of the extension. A global interface used for informing the compositor about applications being activated or started, or for applications to request to be activated. 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. 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. 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. An object for setting up a token and receiving a token handle that can be passed as an activation token to another client. The object is created using the xdg_activation_v1.get_activation_token request. This object should then be populated with the app_id, surface and serial information and committed. The compositor shall then issue a done event with the token. In case the request's parameters are invalid, the compositor will provide an invalid token. Provides information about the seat and serial event that requested the token. Must be sent before commit. This information is optional. The requesting client can specify an app_id to associate the token being created with it. Must be sent before commit. This information is optional. The requesting client can specify a surface to associate the token being created with it. Must be triggered before commit. This information is optional. Requests an activation token based on the different parameters that have been offered through set_serial, set_surface and set_app_id. The 'done' event contains the unique token of this activation request and notifies that the provider is done. Applications will typically receive the token through the XDG_ACTIVATION_TOKEN environment variable as set by its launcher, and should unset the environment variable right after this request, in order to avoid propagating it to child processes. Applications implementing the D-Bus interface org.freedesktop.Application should get their token under XDG_ACTIVATION_TOKEN on their platform_data. Presentation tokens may be transferred across clients through means not described in this protocol. Notify the compositor that the xdg_activation_token_v1 object will no longer be used.
