UCanvasPanel::GetGeometryForSlot
#include "Components/CanvasPanel.h"
Access: public
Specifiers: const
Description
Computes the on-screen geometry (position and size) of a child slot based on the canvas panel's current arranged layout.
Caveats & Gotchas
- • SlotIndex is not bounds-checked — passing an out-of-range index hits a CastChecked assert instead of failing gracefully.
- • Returns false if the slot's Content is null or if the underlying native canvas widget hasn't been constructed yet, in which case ArrangedGeometry is left unmodified.
- • An overload taking a UCanvasPanelSlot* directly also exists; prefer it when you already have the slot pointer to avoid an index lookup.
