Hi,

i know that i can use checkisrunning to detect if the internal render is currently running.
But I also need to know , if the fininshed render is being displayed in the active editor window, bc i need to disble my tool if that is the case.

Is there some way to fnd this out?
I couldnt figure out from the api or using the forum search..
