Struct ImeHandler

Source

pub struct ImeHandler {
    pub inspect_status: InputHandlerStatus,
    /* private fields */
}

Expand description

ImeHandler is responsible for dispatching key events to the IME service, thus making sure that key events are delivered to application runtimes (e.g., web, Flutter).

NOTE: The ImeHandler requires [ModifierHandler] to be installed upstream to apply the keymaps correctly.

Fields§

§inspect_status: InputHandlerStatus

The inventory of this handler’s Inspect status.
