how to use translation/rotation/scale tools in game play mode

Hello everyone,

I am working on an internal architectural visualization project now. 

there are many interaction in program now, such as change furnitures, switch colors etc.

currently, we can move furnitures by dragging or by keyboard. 

we want to use tools such as we used in editor for translation/rotation/scale. Anyone can help to tell how to access them? we have C++ programmers.

Thank you.
