UWidget

class UMG Blueprint Since 4.4

Inherits: UObjectBase › UObjectBaseUtility › UObject › UVisual › UWidget

#include "Components/Widget.h"

Description

The abstract base class for all UMG widgets. Every widget in the widget tree inherits from UWidget, which wraps an underlying Slate SWidget and exposes it to the UObject/Blueprint system.

Caveats & Gotchas

• UWidget is abstract — you cannot instantiate it directly; use concrete subclasses such as UButton, UTextBlock, or UUserWidget.
• The underlying Slate SWidget may not exist yet when a UWidget is first created. Functions that access the SWidget (GetCachedGeometry, GetDesiredSize, etc.) return default values until at least one layout pass has occurred.
