Struct AccessKeyHandler 

pub struct AccessKeyHandler { /* private fields */ }

Handles access keys for a window.

Implementations

impl AccessKeyHandler

pub const TYPE: &'static TypeInfo = <AccessKeyHandler as crate::StaticType>::TYPE

The runtime type of this type.

impl AccessKeyHandler

pub fn access_key_event() -> &'static RoutedEvent<AccessKeyEventArgs>

Defines the AccessKey event: raised on the element an access key targets.

pub fn access_key_pressed_event() -> &'static RoutedEvent<AccessKeyPressedEventArgs>

Defines the AccessKeyPressed event: raised to find the target of an access key.

impl AccessKeyHandler

pub fn show_access_key_property() -> &'static AttachedProperty<bool>

Defines the ShowAccessKey attached property: whether access key markers are shown in a window.

impl AccessKeyHandler

pub fn new() -> Rc<AccessKeyHandler>

Creates an access key handler without an owner.

pub fn registration_count(&self) -> usize

The number of registered access keys, including registrations of elements that are no longer alive and have not been purged yet.

pub fn registrations(&self) -> Vec<(String, Ref<InputElement>)>

The registered access keys with the elements they target (the ones that are still alive). For handlers built on this one.

pub fn set_owner_with( &self, owner: &Ref<InputElement>, on_set_owner: impl FnOnce(&Ref<InputElement>), )

Sets the owner of the handler as IAccessKeyHandler::set_owner does, with the key and pointer handlers attached, and then runs on_set_owner: the OnSetOwner virtual of the class, which does nothing in this class and which a handler built on this one overrides (the handler of a menu item attaches its text input handler there).

This method can only be called once.

pub fn on_preview_key_down(&self, e: &KeyEventArgs)

Called when a key is pressed in the owner window, before the event reaches the focused element.

pub fn on_key_down(&self, e: &KeyEventArgs)

Called when a key is pressed in the owner window.

pub fn on_preview_key_up(&self, e: &KeyEventArgs)

Handles the Alt/F10 keys being released in the window.

pub fn on_preview_pointer_pressed(&self, _e: &PointerPressedEventArgs)

Handles a pointer press in the window: hides the access key markers.

pub fn process_key( &self, key: Option<&str>, element: Option<&Ref<InputElement>>, ) -> bool

Processes an access key: raises the AccessKey event on the element the key targets. Returns whether a target was found.
