Enum fidl_fuchsia_element::GraphicalPresenterRequest

pub enum GraphicalPresenterRequest {
    PresentView {
        view_spec: ViewSpec,
        annotation_controller: Option<ClientEnd<AnnotationControllerMarker>>,
        view_controller_request: Option<ServerEnd<ViewControllerMarker>>,
        responder: GraphicalPresenterPresentViewResponder,
    },
}

An interface used to instruct a server to present graphical views, and observe and control the view’s lifecycle.

Variants

PresentView

Fields

view_spec: ViewSpec

annotation_controller: Option<ClientEnd<AnnotationControllerMarker>>

view_controller_request: Option<ServerEnd<ViewControllerMarker>>

responder: GraphicalPresenterPresentViewResponder

Presents the view described by view_spec.

If view_controller_request is provided, it will be connected to a ViewController implemented by the GraphicalPresenter server. When the view is dismissed, the ViewController channel is closed with a ZX_OK, at which point it is safe to clean up resources backing the view. To dismiss the view, the client should call ViewController.Dismiss() and wait for the ZX_OK epitaph. Not providing a view_controller_request handle will make it impossible for the client to observe the view’s lifecycle.

• view_spec describes the view to present
• annotation_controller a handle to an AnnotationController, allowing the GraphicalPresenter server to observe and update the view’s annotations.
• view_controller_request an optional request for a controller for the view

• error view_spec must contain view_holder_token and view_ref for Gfx views, OR viewport_creation_token for Flatland views, but never both. If both are set, error PresentViewError.INVALID_ARGS is returned.
• error PresentViewError.INVALID_ARGS if spec.view_holder_token or spec.view_ref are missing or invalid.
