I've done a lot of searching on the web and in this forum, so I'm guessing I have not used the right search terms (or I'm the first to want to do this...which would be a first for me to have an original idea ).

I'm writing an audio oriented app in PyQt the normal scales for audio are log based.

So, what I want to do is display a slider that has ticks in a log spacing along the slider (i.e. not linear, in this particular case it would be decibels).

I have sliders and I already map the range of the slider to decibels for numerical display of the value, but have only figured out how to get ticks to be linear along the slider.

Since I haven't found any examples or even (at least to me) hints as how to attempt this, any pointers to docs or ideas are much appreciated.

Thanks,
Mac
