FGeometry::GetLayoutBoundingRect
#include "Layout/Geometry.h"
Access: public
Specifiers: FORCEINLINE_DEBUGGABLEconst
Description
Returns the axis-aligned bounding rectangle of this geometry in absolute space, computed using the accumulated layout transform (without render transforms).
Caveats & Gotchas
- • Ignores render transforms — if a widget has a rotation or skew render transform, the layout bounding rect will not match what is visually rendered on screen. Use GetRenderBoundingRect() for the visual footprint.
- • The rect is in the same absolute coordinate space as AbsolutePosition — window space or desktop space depending on the widget hierarchy root.
- • Overloads accepting FMargin or FSlateRect allow you to extend or restrict the rect before transforming, which is more efficient than computing the bounding rect and then modifying it.

FSlateRect Example
Culling: skip paint if rect is outside clip region C++
FSlateRect LayoutBounds = MyGeometry.GetLayoutBoundingRect();
if (!FSlateRect::DoRectanglesIntersect(LayoutBounds, MyCullRect))
{
return; // Fully culled, skip expensive paint
