Hi guys,
I wanted to know is there a way to make imrect show its x and y length while the user is moving it inside the axes. Is there something like a callback so i can get that data and display it next to the rectangle as the user resizes it.

See the Example 1 in doc imrect.

Wow, who ever would have guessed that code? Sometimes it seems like they go out of their way to make programming more difficult. I haven't tried it but it looks like they are putting the coordinates in the title of the axes, so if you had something there, you'll have to restore it. And I'm wondering if it blasted past the imrect call (so that it can do the addNewPositionCallback call) if you'll need a "position = wait(h);" line (as in their second example), otherwise it will go along blasting through all the rest of your code too, which you probably don't want.
