FGeometry::GetRenderBoundingRect

function SlateCore Since 4.14

#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 full accumulated render transform, including any rotation or skew.

Caveats & Gotchas

• For widgets with rotation, the bounding rect will be larger than the widget's visual size because it must encompass the rotated corners. This is not the tight oriented bounding box — use FSlateRotatedRect if you need that.
• More expensive than GetLayoutBoundingRect because the render transform may involve a matrix inversion. Avoid calling in tight per-frame loops.
• Like GetLayoutBoundingRect, overloads exist to extend the local-space rect before transforming, useful for adding hit-test padding.

Signature

FORCEINLINE_DEBUGGABLE FSlateRect GetRenderBoundingRect() const

Return Type

FSlateRect

Example

Draw a debug outline around the rendered widget bounds C++

FSlateRect RenderBounds = MyGeometry.GetRenderBoundingRect();
// Use RenderBounds.Left/Top/Right/Bottom for overlay drawing.
FSlateDrawElement::MakeBox(OutDrawElements, LayerId,
	MyGeometry.ToPaintGeometry(),
	FAppStyle::GetBrush("Debug.Border"));
