- CueFader is hopefully done: - CueFader is hopefully done: - The TimedGoButton accepts a wheel to change the times. You can also enter times directly. - TimedGoButton really has a default starting time of 2 now. (there was a variable attached to the wrong widget before) - We send DMX levels with dmxclient now. - Autoload Times is a new option. - We load times from the next cue if Autoload Times is true. - Time predictions in the LabelledScale are slightly better. You still can change the time of an active fade. - Cue cache and DMX level computing now have their own functions, which get called at (hopefully) All The Right Times. - There are even some docs now! - Cues: sub_level parsing is better, will only throw out one line if it encounters problems (instead of the rest of the cue) - CueList: lots of 0 vs. None bugs fixed. - TkCueList: stores a reference to the controlling fader so it can alert it about changed cues. - CueEditron: You can edit sub_levels now. - cuelist1 was edited, checking it in for consistency's sake
