How to connect the OS X dictionary

Question

on osx lion, you can control-command-d or triple-click on the word your mouse is pointing to in any application to launch the popover dictionary. I want to make an application for tracking words that a user is looking for in a dictionary.

how can I observe an event when the user executes the control-command-d command or triple-click to start the popover dictionary?

I understand the specific API for this HIDictionaryWindowShow .

You can use popoverDidShow:

- (void)awakeFromNib { NSNotificationCenter* notificationCenter = [NSNotificationCenter defaultCenter]; [notificationCenter addObserver:self selector:@selector(popoverDidShow:) name:NSPopoverDidShowNotification object:nil]; } // dictionary is shown or another NSPopover - (void)popoverDidShow:(NSNotification*)notify { //your code }
