callbacks.addScript #viewportChange

,where can l find this type of callback in the max sdk?

Are you looking for this?

[B]fn redrawviews_p = print “Viewports Redrawn”

registerRedrawViewsCallback redrawviews_p[/B]

It will call the function whenever the active viewport gets redrawn. Search for “registerRedrawViewsCallback” in the MaxScript help file.

Thanx for your reply . what I actually want to do is

I find this type of callback in maxscritp:
#viewportChange: undefined

Sent everytime the viewport parameters change, including panning, zooming and orbiting the viewport or changing the active viewport. Currently, there is no notification for viewport layout change.



callbacks.removeScripts id:#keepFaceToScreenCallback
callbacks.addScript #viewportChange "keepFaceToScreenCallback() " id:#keepFaceToScreenCallback

Now , I want to accomplish the same with the SDK API
