|  | gpointer | user_data

fl_keyboard_manager_handle_event: @manager: an #FlKeyboardManager. @event: the event to be dispatched. It is usually a wrap of a GdkEventKey. This event will be managed and released by #FlKeyboardManager. @cancellable: (allow-none): a #GCancellable or NULL. @callback: (scope async): a #GAsyncReadyCallback to call when the view is added. @user_data: (closure): user data to pass to @callback.

Make the manager process a system key event. This might eventually send messages to the framework, trigger text input effects, or redispatch the event back to the system.

## ◆ fl_keyboard_manager_new()

FlKeyboardManager* fl_keyboard_manager_new | ( | FlEngine * | engine | ) |

FlKeyboardManager:

Processes keyboard events and cooperate with `TextInputManager`.

A keyboard event goes through a few sections, each can choose to handle the event, and only unhandled events can move to the next section:

- Keyboard: Dispatch to the embedder responder and the channel responder simultaneously. After both responders have responded (asynchronously), the event is considered handled if either responder handles it.
- Text input: Events are sent to IM filter (usually owned by `TextInputManager`) and are handled synchronously.
- Redispatching: Events are inserted back to the system for redispatching. fl_keyboard_manager_new: @engine: an #FlEngine.

Create a new #FlKeyboardManager.

Returns: a new #FlKeyboardManager.
