This is a analog scale widget. It might be interesting especially in case you want to write nice GUIs for laboratory devices (as I did) or you want a freaky monitoring widget.
It is fully resizable and supports a horizontal as well as vertical scale.
The scale is completely derived from the scale range and the geometry (it is also possible to control the steps manually).
I've made some screenshots where I've just changed min, max and current value (resizing was done after running).
In the last screenshots I showed the hiding of scale and values and changed my desktop color scheme.
If you use the widget, I'd be glad if you leave a comment. This might encourage me to create a Designer plugin or do other further work at other parts of the code.
