- 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
