how to enable a timer in a non-gui thread?

[zeopha]

I have a non-gui thread to process db files , and I want a slot located in this thread to check the db files every a threshold assigned by a QTimer. the slot will emit a signal to post information to a gui thread to show db files' status. but the slot connected to this timer won't work in this thread.
I don't want to use such soluton:
this timer was located in the gui thread and was connected a slot located in that non-gui thread.

how can I enable this timer in such non-gui thread in some other solution?

any help will be appreciated!
