Calling UUserWidget buttons from integer input

Just wanted to say that I solved it, but I went into SCompoundWidget class and used slate instead. For those that are searching for the answer of how to change tab with input from HUD. In your SCompoundWidget header:

//...
	void UpdateTab(int32 InputTabIndex);

private:

	int32 TabIndex;
	//Getter
	int32 GetCurrentTabIndex() const { return TabIndex; }
//...

in your SCompoundWidget cpp:

//...
	SNew(SWidgetSwitcher) //Tab1
	.WidgetIndex(this, &SMyCompoundWidget::GetCurrentTabIndex)
	+SWidgetSwitcher::Slot()
	[
	//...
	]
	+ SWidgetSwitcher::Slot() //Tab2
	[
	//...
	]
	+ SWidgetSwitcher::Slot() //Tab3
	[
	//...
	]
//...
}

void SMyCompoundWidget::UpdateTab(const int32 InputTabIndex)
{
	TabIndex = InputTabIndex;
}

The function UpdateTab is called from MyHud with the int32 using value 0,1,2. I used this tutorial as guidance
