In case of editing KEYFRAME in graphEditor, I can use MAnimMessage and it's belongings.
But, I hope to get MESSAGE when I change view of graphEditor.
For example, while tracking the view of graphEditor with mouse dragging and change the time range, I get the start and end time of graphEditor.
And, additionally, how can I GET the time range of graphEditor?
I can set with "animView" command, but it can support "query" flag.
Is there any way to get the range?
