Required Methods§

Source

fn set_owner(&self, owner: &Ref<InputElement>)

Sets the owner of the keyboard navigation handler.

This method can only be called once, typically by the owner itself on creation.

Source

fn move_( &self, element: Option<&Ref<InputElement>>, direction: NavigationDirection, key_modifiers: KeyModifiers, device_type: Option<KeyDeviceType>, ) -> bool

Moves the focus in the specified direction.

element is the current element, key_modifiers any key modifiers active at the time of focus and device_type the optional key device type that caused the move.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
