UBorder::BackgroundDelegate

property UMG Since 4.0

#include "Components/Border.h"

Access: public Specifiers: UPROPERTY

Description

Bindable delegate backing the Background brush property binding in the UMG Designer, letting the brush be driven from a bound function each frame.

Caveats & Gotchas

• Normally populated by the 'Bind' dropdown next to Brush in the Details panel rather than assigned directly in most workflows.
• Unlike ContentColorAndOpacityDelegate and BrushColorDelegate, Background has no PROPERTY_BINDING_IMPLEMENTATION macro — its binding is evaluated separately in SynchronizeProperties.

Signature

FGetSlateBrush BackgroundDelegate

Example

Bind the background brush to a function C++

// GetActiveBrush is a UFUNCTION(BlueprintPure) declared on UMyUserWidget returning FSlateBrush
void UMyUserWidget::NativeConstruct()
{
    Super::NativeConstruct();
    if (MyBorder)
    {
        MyBorder->BackgroundDelegate.BindDynamic(this, &UMyUserWidget::GetActiveBrush);
    }
}
