Enum fidl_fuchsia_ui_keyboard_focus::ControllerRequest

pub enum ControllerRequest {
    Notify {
        view_ref: ViewRef,
        responder: ControllerNotifyResponder,
    },
}

Updates the focus of the keyboard subsystem.

Roles

This protocol will typically be:

• Implemented by platform components implementing the keyboard subsystem.
• Consumed by platform components which control UI policy. E.g. Root Presenter, or the Workstation Session.

Related protocols

• fuchsia.ui.input3.Keyboard (for receiving keystrokes)
• fuchsia.ui.input.InputMethodEditor (for text editing)

Variants

Notify

Fields

view_ref: ViewRef

responder: ControllerNotifyResponder

Informs the implementer of Controller that further keyboard data should be routed to the keystroke/text consumer associated with view_ref.

Notes

• The callee should monitor the provided ViewRef for a ZX_EVENTPAIR_PEER_CLOSED signal (see documentation for fuchsia.ui.views.ViewRefControl).
• When the ViewRef receives ZX_EVENTPAIR_PEER_CLOSED, the callee should stop delivering keystroke/text to the consumer associated with view_ref.
• The caller should wait for each call to be acknowledged before calling again, to avoid queueing large numbers of of updates.
