Wait a minute... I didn't make the object bar! But i CAN tell you that the font that I used in the DX theme is called "Dungeon", and the size is 11. You could have right clicked on any of the shortcuts in the drop down menu's, gone to "appearance", then on "change font", and you would have seen it. But, you'll know next time.
If you need any more help, let me know.
