Interface ICrossMenuHost

Implemented by a composite that hosts a stack of menus and coordinates cross-menu focus traversal: when a menu reaches a navigation boundary it asks its host to move focus to the adjacent sibling.

Namespace: Serenity.Ui.Application.Interfaces.Views

Assembly: Serenity.Ui.Application.dll

Syntax

public interface ICrossMenuHost

Methods

SetCrossMenuConfig(bool, bool)

Enables cross-menu focus traversal between this host's menu children (up/down at boundaries).

Declaration

void SetCrossMenuConfig(bool enabled, bool wrapAround)

Parameters

Type	Name	Description
bool	enabled	Whether traversal is on.
bool	wrapAround	Whether traversal wraps the whole stack vs stops at the ends.

TryMoveFocus(IFocusableMenuView, bool)

Moves input focus from current to the adjacent sibling menu in the stack — the next one when forward (down past the last option), the previous one otherwise (up past the first). Focuses the sibling's first option (forward) or last option (backward) and clears current's highlight.

Declaration

bool TryMoveFocus(IFocusableMenuView current, bool forward)

Parameters

Type	Name	Description
IFocusableMenuView	current	The menu focus is leaving.
bool	forward	True for downward/next, false for upward/previous.

Returns

Type	Description
bool	True when focus moved to a sibling; false when at the stack end with wrap-around off (stop).
