Edit Toolbar - Constrain proportions?

[MarkSchumaker]

I'm trying to implement a simple shape editor for my map using the edit toolbar. I have it working but I'm wondering if there is any way to constrain the proportions of the shape. Like Photoshop, where you hold shift or something similar.

My only thought is that you could connect to the onscale event and constrain them from there... But I can't find any way to do it.

Any thoughts?

Hi mark,

i'm not allone with this need. Do you implement such functionality, yet? I found the onScale-Event too and searched for the function, which trigger this Event. But nothing found. If you know the function, which trigger the onScale-Event, you can inherit from it and write your own functionality. There you have to scale to Y with the same value of X-direction.
Do you know, where the onScale-Event is been triggered?
