Enum ViewRequest

Source

pub enum ViewRequest {
    Present {
        view_token: ViewToken,
        control_handle: ViewControlHandle,
    },
}

Expand description

Deprecated API for view creation. DO NOT USE.

Variants§

§

Present

Provides the View with an attachment point to Scenic’s scene graph.

When Present() is called the View’s implementation should create a View resource within Scenic by providing it with the view_token (using a fuchsia.ui.gfx.CreateResourceCmd and fuchsia.ui.gfx.ViewArgs).

Then the implementation should attach its graphical content to the newly-created View resource using a fuchsia.ui.gfx.AddChildCmd.

If the implementation already owns a View resource (because Present() had already been called before), then it should terminate the connection with an error.

TODO(https://fxbug.dev/42098670): Allow re-parenting Views with a new Present() call.
