USlateBlueprintLibrary::LocalToAbsolute

function UMG Blueprint Since 4.7

#include "Blueprint/SlateBlueprintLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Transforms a point from a widget's local space into absolute Slate space using the widget's accumulated render transform. This is the Blueprint-accessible wrapper around FGeometry::LocalToAbsolute.

Caveats & Gotchas

• Returns coordinates in Slate's absolute space, which is window-relative in most in-game contexts. To obtain viewport pixel coordinates for use with DeprojectScreenToWorld or line traces, pass the result through LocalToViewport instead.
• Requires the geometry to be fully up-to-date; calling this during PreConstruct or before the first layout pass may return zero or stale results.

Signature

static UMG_API FVector2D LocalToAbsolute(const FGeometry& Geometry, FVector2D LocalCoordinate)

Parameters

Name	Type	Description	Default
Geometry	const FGeometry&	The geometry of the widget whose local space you are converting from. Obtain via GetCachedGeometry() or event parameters.	—
LocalCoordinate	FVector2D	Point in the widget's local space, where (0,0) is the top-left corner.	—

Return Type

FVector2D

Example

Blueprint: convert widget top-left corner to absolute space C++

// C++ equivalent of the Blueprint node:
FVector2D AbsPos = USlateBlueprintLibrary::LocalToAbsolute(
	MyWidget->GetCachedGeometry(),
	FVector2D::ZeroVector // top-left of the widget
);
