CollectFocusKeys()

IReadOnlyList< string > ConsoleForge.Core.FocusManager.CollectFocusKeys ( IWidget root )

static

Collect the focus key of every IFocusable in the tree rooted at root , in depth-first, declaration order.

A widget whose IFocusable.FocusKey is null is skipped — it is not a focus target.

FindFocusableAt()

? IFocusable ConsoleForge.Core.FocusManager.FindFocusableAt ( IWidget root, ResolvedLayout layout, int col, int row )

static

Returns the IFocusable whose allocated region in layout contains the point (col , row ), or null if none.

When multiple widgets overlap (e.g. inside a ZStack), the last one in depth-first order wins (topmost layer).

GetNext()

? string ConsoleForge.Core.FocusManager.GetNext ( string? currentKey, IReadOnlyList< string > keys )

static

Return the key after currentKey in keys , wrapping past the end.

If currentKey is null or not present, returns the first key. Returns null if keys is empty.

GetPrev()

? string ConsoleForge.Core.FocusManager.GetPrev ( string? currentKey, IReadOnlyList< string > keys )

static

Return the key before currentKey in keys , wrapping past the start.

If currentKey is null or not present, returns the last key. Returns null if keys is empty.
