Constant MODAL
pub const MODAL: FocusScopeType;Expand description
Modal overlay blocks the key and touch input that originates from outside its boundaries and keeps the focus navigation within the overlay boundaries, just like a focus fence. Every Kanzi application has at least one modal overlay: the Screen node.
When input occurs outside the boundaries of a modal focus scope, Kanzi dispatches the FocusManager::InputOutsideOverlayMessage to the focus scope node.
