UUserWidget::SetVisibility

function UMG Blueprint Since 4.5

#include "Blueprint/UserWidget.h"

Access: public Specifiers: virtual

Description

Sets the visibility of the widget, controlling both rendering and hit-test behaviour. Common values are Visible, Hidden (not rendered, still takes up space), Collapsed (not rendered, takes no space), and HitTestInvisible.

Caveats & Gotchas

• Hidden and Collapsed are different: Hidden leaves layout space, Collapsed does not. Switching between them can cause layout shifts.
• ESlateVisibility::HitTestInvisible renders the widget but passes all input through to widgets below — useful for overlays that display info but shouldn't block clicks.
• Visibility changes on a parent do not automatically propagate to children in a way that GetVisibility() reflects — child visibility is independent.
