And what gtk3 wigits there is available has been emasculated, with zero thoughts of updateing to include wigits similar to what gtk2 had on the menu. So until that occurs, here its tcl/tk wrapped in pyvcp to the rescue. The gfx are of a coarser grained construction to be sure, but they _still_ work. One thing I have yet to add to the latest gui additions are some background colorizations to indicate state/mode of the dials. I'd like to have 3 colors, yellow for jog size setting mode, green for dial active, and red for disabled. I have some 2 color setups elsewhere, but haven't tried for 3 in one box yet. But since the label is a box, and the value is a box below, I may have to settle for 2 different colors of each to get all states/modes accounted for.
