Hello, NSOutlineView is almost the same as NSTableView. Wire the NSOutlineView to an instance that acts as a datasource and a delegate, and then responds to message to populate the NSOutlineView.
See: http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSOutlineView_Class/Reference/Reference.html http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Protocols/NSOutlineViewDataSource_Protocol/Reference/Reference.html#//apple_ref/occ/cat/NSOutlineViewDataSource As noted in the documentation, the view does not store any data, so the view asks for data as needed. Your model should typically include some sort of unique key that is used to identify the data row (you can use a static int counter). When the NSOutlineView needs to display something, it will ask for the data by passing the column identifier and the unique key. You can also take a look at the Cocoa samples in the SDK. There is a sample about NSOutlineView. Regards, Laurent Etiemble. 2009/1/12 Mario De Clippeleir <mari...@sydec.be>: > Hi, > > > > Does anybody have experience with NSOutlineView ?
