Interface IFocusableMenuView

A menu that participates in composite cross-menu focus traversal. Lets a composite (which lives in a lower layer that cannot reference the concrete menu type) move input focus between sibling menus, query/place the option selection, and gate whether the menu currently receives input.

Methods

BlurFocus()

Parameters

Declaration

void SetCrossMenuHost(ICrossMenuHost host, bool wrapAround)

Parameters

Type	Name	Description
ICrossMenuHost	host	The composite that owns the stacked sibling menus, or null to disable.
bool	wrapAround	Whether traversal wraps around the whole stack vs stops at the ends.

SetInputActive(bool)
