Struct KeyboardDevice 

pub struct KeyboardDevice { /* private fields */ }

Represents the keyboard: turns raw key and text input into routed events on the focused element, and is the source of truth about which element has keyboard focus.

Implementations

impl KeyboardDevice

pub fn new() -> Rc<KeyboardDevice>

Creates a keyboard device.

pub fn instance() -> Option<Rc<KeyboardDevice>>

The keyboard device registered with the locator (as dyn IKeyboardDevice), if it is a KeyboardDevice.

pub fn input_manager(&self) -> Option<Rc<dyn IInputManager>>

The input manager registered with the locator.

pub fn focus_manager(&self) -> Option<Rc<dyn IFocusManager>>

The focus manager registered with the locator.

pub fn property_changed( &self, handler: impl Fn(&str) + 'static, ) -> Rc<dyn IDisposable>

Raised with the name of a property of the device that changed ("FocusedElement").

pub fn focused_element(&self) -> Option<Ref<InputElement>>

The element that has keyboard focus.

pub fn set_focused_element( &self, element: Option<&Ref<InputElement>>, method: NavigationMethod, key_modifiers: KeyModifiers, )

Moves keyboard focus to an element (or clears it); the change can be cancelled or redirected by LosingFocus/GettingFocus handlers.

pub fn set_focused_element_with( &self, element: Option<&Ref<InputElement>>, method: NavigationMethod, key_modifiers: KeyModifiers, is_focus_change_cancellable: bool, )

Moves keyboard focus to an element (or clears it).

is_focus_change_cancellable tells whether LosingFocus and GettingFocus handlers may cancel or redirect the change.

Trait Implementations

impl IInputDevice for KeyboardDevice

fn process_raw_event(&self, e: &dyn IRawInputEventArgs)

Processes raw event. Is called after preprocessing by the input manager.

fn as_any(&self) -> &dyn Any

The device as Any, for downcasting to the concrete device.

fn as_pointer_device(&self) -> Option<&dyn IPointerDevice>

The device as a pointer device, if it is one.
