Hi All,
I met with a problem when I made PDE with cocoa:
I can't catch the event that user presses [Print] button, in carbon PDE, I can get the ControlRef of [Print] button and install event handler to it. However, in cocoa, I can only get the NSButton * pointer of [Print] button, but I can't install event handler to NSControl in cocoa. I can only use the event in NSResponder. But NSResponder doesn't provide the event that handles the clicking of [Print] Button.
Who knows how I can catch the event that user clicks [print] Button in cocoa? Or who knows how to install event handler to a special NSControl in cocoa?
Best Regards
Jeff Chen
