How to change tracker position to put on the top but like the windows menu

How i can change tracker to put on the top but in the way that is occupied all of the top from the left to the right.

I guess you mean the Deskbar, not Tracker?
From the userguide: drag the knob (in its default position it is to the right of the clock in the tray) to the wanted area. If you want something like the one marked as B_DESKBAR_TOP here, that would be to the top of your screen.

Thank you very much i aprecciate it.
