Trigger ruby on SU8 model changes

[krisjaniszakis]

Hi,

Is there any one who has answer to question.
How to catch (on the fly) with Ruby script any changes(drawing, painting) that user is doing in active model.

I basically don't care what he is doing I need to know that he is doing something to model.

Probably use the transaction observer - triggers when something is added to the undo stack. But not that a transaction != operation. Many transactions trigger in between an operation. And it triggers A LOT!!!! So be very careful with that you do there. You can esily slow down SU. But if you set a simple boolean ( @changed = true ) you might be ok. But you should profile this to be sure.
Also - never modify the model at these events - that's begging for a bugsplat.
