I have an UserWidget window ( with blueprint code ). It call an event “close” when button pressed. And the window closes.
I need to catch this event in my C++ code.

I make a parent C++ class UInventoryWindow for this widget.

The first way was:

	UFUNCTION(BlueprintNativeEvent, BlueprintCallable, Category = "CloseEvent")
		void close();

	void close_Implementation();

but does not works. I have a blueprint compilation error

[Compiler] close  name conflicts with a native 'InventoryWindow' function

The second way: I overridden the SetVisibility function in my UInventoryWindow class. But it is the bad way

void UInventoryWindow::SetVisibility(ESlateVisibility InVisibility)
{
	UGameplayStatics::SetGamePaused(GetWorld(), false );

	UUserWidget::SetVisibility(InVisibility);

	RemoveFromParent();
}
