Can you lock only certain sliders in multislider?
so you can draw over it and only certain sliders will be affected? Only even/odd, only every 3rd, etc.
I guess you could do it programatically, but visually? (except by having an invisible multislider on top and visible one beneath. Did I answer my own question?
No it can't be done, point.
You have to program own multislider external, having available arguments to ignore
certain sliders on the fly.
The set message can individual sliders by index.
This might look as if it worked, but in reality only visually.
When one drags with mouse over sliders they send out the draged values,
so whatever mechanism is listening to multislider values would receive the
changed values.
Only possible solution is mousefiltering output, but then You have no value change
while moving a mouse...
