I made it in some way, but I don't like it...

I tried to put it on a paintEvent (the alternative code is commented in 
the patch), but I had two problems (I'm so newbie on Qt... could anyone 
help me with this?):
    - When i create a QPainter object sometimes I got (I need to filter 
certain QPaintEvent (s)?):

    QPainter::begin: Widget painting can only begin as a result of a paintEvent

    - I didn't know how to update the widget from the OverProcessing 
slot, to make it call to paintEvent...

So, I putted a simple QToolTip::showText direct from the slot.

(The last days I was finishing some readings about C++... I'll need to 
use this next days to read about Qt!...)

I did it. But anyway, I putted some "hardcoded" checks to take away 
"icon" attributes, empty values and values equals to the main key name 
-i.e. empty descriptions-. Do you think is better now?

Best regards,
