How to make action of other application?

Question

Greetings, I need to make action in other (not mine) application. Lets say, Photoshop toolbar. Is there any way to click any button of Photoshop's toolbar from my cocoa application?

...

I found:
- NSRunningApplication
- Accessibility API
- Quartz Events
- ...and this

But it's still not enought. Any idea? Any solution?

Thanks and have a nice day!

Answer 1

Accessibility or the ways described in that forum thread are the only two ways to manipulate an application that doesn't invite other applications to manipulate it.
