How to detect mouse is over any Widget?

[xlman (Nadav Heksekman)]

	FWidgetPath Path = FSlateApplication::Get().LocateWindowUnderMouse(FSlateApplication::Get().GetCursorPos(), FSlateApplication::Get().GetInteractiveTopLevelWindows(), true);
	TSharedPtr vp = FSlateApplication::Get().GetGameViewport();
	bool overViewPort = Path.IsValid() && (Path.GetLastWidget() == vp.ToSharedRef());

You can use that bool overViewPort to check if the mouse is over the game viewport or any UI.

For whoever trying the great solution above but is getting complication errors.

Don’t forget to include:
include “Widgets/SWidget.h”
include “Widgets/SViewport.h”

Otherwise complier can’t know how to compare the two. Good luck!
