Hello,

I need to use the QwtThermo gauge with a range let's say between -100 and +100.
I want the liquid fills from 0 to the current value.

In other words, if value is 0 no liquid should be visible, if value is > 0 the liquid will fill on the right form the center and so on.

I read through the documentation but I can't find such a feature. So I'm going to subclass the drawThermo function to implement this. There is an example of how to subclass qwtThermo?

Thanks
Marco
