First of all, I'm trying to port to Max2020 from a max2012 code.
I have a rolloutpanel with a ParamBlk INode button (TYPE_PICKNODEBUTTON). When I update this INode by SetNoteTM(), the whole rollout (but only the one which holds this button) gets "refreshed" somehow. Since there are many other controls on this panel, this refresh takes a while, makes my code slow and is very visible (maybe due to QT, which makes the UI not faster). I am wondering, why the panel shall get updated at all, since nothing relevant changes in the scene?
Max2012 does not show this behaviour - or I simply can't see it, if the update process is 100 times faster..
