Hi, im trying to realize left and right click on my widget. When I click the right or left mouse button - Click function fires and im want to get IsInputKeyDown and it always false. A feeling that IsInputKeyDown apply before event bind fires tick and again becomes to false or it happens after bind event tick. How to fix it or any alternatives?

bool UClickableWidget::CreateButton()
{
	Button = Cast<UBorder>(GetWidgetFromName(FName("Border_PlusPlus")));
	if (Button)
	{
		Button->OnMouseButtonDownEvent.BindUFunction(this, FName("Click"));
		return true;
	}
	return false;
}

void UClickableWidget::Click()
{
	if (GetWorld()->GetFirstPlayerController()->IsInputKeyDown(EKeys::LeftMouseButton))
	{
		LeftClick();
		return;
	}
	if (GetWorld()->GetFirstPlayerController()->IsInputKeyDown(EKeys::RightMouseButton))
	{
		RightClick();
		return;
	}
}

I have decided this task. it looks like a garbage collection system principle. In Click function i set ClickCalled variable to true and on next tick check for it and here clicked button already testable.

void UClickableWidget::NativeTick(const FGeometry& MyGeometry, float InDeltaTime)
{
	Super::NativeTick(MyGeometry, InDeltaTime);

	if (ClickCalled)
	{
		ClickCalled = false;
		if (GetWorld()->GetFirstPlayerController()->IsInputKeyDown(EKeys::LeftMouseButton))
		{
			LeftClick();
			return;
		}
		if (GetWorld()->GetFirstPlayerController()->IsInputKeyDown(EKeys::RightMouseButton))
		{
			RightClick();
			return;
		}
	}
}

 bool UClickableWidget::CreateButton()
 {
     Button = Cast<UBorder>(GetWidgetFromName(FName("Border_PlusPlus")));
     if (Button)
     {
         Button->OnMouseButtonDownEvent.BindUFunction(this, FName("Click"));
         return true;
     }
     return false;
 }

 void UClickableWidget::Click()
 {
     ClickCalled = true;
 }
