Is there a way to call a class in a global namespace?

I have a tough time wording this question but here's my code to start:

namespace UserInterface
{
   class UiClass
   {
   };
}

namespace Project
{
   namespace UserInterface
   {

   }
}


namespace Project
{
   UserInterface::UiClass uiClass;
}

So that code won't work because a UserInterface is a global namespace but it's also inside Project so when I instaniate UiClass inside Project it tries to look inside Project->UserInterface instead of just UserInterface. Is there a some way to be specific that I want to use the global UserInterface and not the one inside Project or do I need to change my design?

You can force the name lookup to begin at the global scope using a leading ::.

::UserInterface::UiClass uiClass;
