UEyelinkUserWidgetBase¶

A base UMG widget class for binding Eyelink graphics callbacks to UI elements.

Syntax¶

class UEyelinkUserWidgetBase : public UUserWidget

Remarks¶

Subclass this widget in UMG to implement the visual side of Eyelink calibration. The calibration-related Blueprint-implementable events are invoked automatically once the delegates are bound via BindEyelinkDelegates. UCLASS
