Salam,

I think your means that when you rotate an object the direction of Gizmo has been changed.. means goes to its default position.

Very simple, select object, hold down "W" key and left click and choose "Object" from the menus. It will make the Gizmo in the direction of an object. An you can rotate or scale or move in the direction of an object. Hope it will help.

I think you were wanted as in my thought.
