Detailed Description

Stateless helper that traverses a widget tree depth-first and finds all IFocusable instances in declaration order.

Member Function Documentation

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()

? IFocusable ConsoleForge.Core.FocusManager.GetNext ( IFocusable? current, IReadOnlyList< IFocusable > all )

static

Return the next focusable after current (wrapping).

If current is null or not found, returns the first item. Returns null if all is empty.

GetPrev()

? IFocusable ConsoleForge.Core.FocusManager.GetPrev ( IFocusable? current, IReadOnlyList< IFocusable > all )

static

Return the previous focusable before current (wrapping).

If current is null or not found, returns the last item. Returns null if all is empty.
