The overridable members introduced by the class.

Provided Methods§

Source

fn should_trigger_selection( this: &Self, selectable: &Visual, event_args: &PointerEventArgs, ) -> bool

Analyses a pointer event received by a selectable element, and determines whether the action should trigger selection on press, on release, or not at all.

Source

fn should_trigger_selection_key( this: &Self, selectable: &Visual, event_args: &KeyEventArgs, ) -> bool

Analyses a key event received by a selectable element, and determines whether the action should trigger selection.

Source

fn update_selection_from_event( this: &Self, container: &Ref<Control>, event_args: &dyn IRoutedEventArgs, ) -> bool

Updates the selection based on an event that may have originated in a container that belongs to the control.

Returns true if the event originated from a container that belongs to the control and triggered selection; otherwise false.

Dyn Compatibility§

This trait is not dyn compatible.

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