Signature

virtual void SetVisibility(ESlateVisibility InVisibility)

Parameters

Return Type

void

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.

Example

Toggle widget visibility C++

// Show/hide without affecting layout:
MyWidget->SetVisibility(bShow ? ESlateVisibility::Visible : ESlateVisibility::Hidden);

// Show/hide and collapse layout space:
MyWidget->SetVisibility(bShow ? ESlateVisibility::Visible : ESlateVisibility::Collapsed);
