Is it possible to get an event when you click on a token in a NSTokenField?
回答1:
Seeing as those tokens (NSTokenFieldCells) inherit from the NSCell class, in theory, yes, you can have them send an event by giving them an action and a target (-setAction: and -setTarget: respectively, and if you want to give the tokens menus when pressed, use -setMenu:).
