Hi All,

I'm writing a plugin for an application. I cannot derive from NSApplication as it is a third party application. I can get the callback in my plugin when any key is pressed. But I will not know what key is pressed. So is there any call in Cocoa to find the last key pressed when I get the callback? I only have NSView object.

Any ideas will help me a lot.

Thanks,

Dheeraj.
