You probably shouldn't even try. Despite superficial appearances, NSComboBox is a kind of text field, *not* a kind of menu. If the intent is to choose an object from a list of objects, NSComboBox is definitely not the way to go about it. Only use NSComboBox where you want text entry, but also want to accelerate the text entry by providing several pre-determined strings. Otherwise, use a menu or a NSPopUpButton instead. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
