On Mac OS X, look for NSTableViewDelegate tableView:heightOfRow:. The width is set through the NSTableColumn which has an entire set of methods to set the minimum width, the width and the maximum width.

As you can see during the creation of NSTableCellView I'm basically using an NSZeroRect because [cellView frame] is nil. I subclassed NSTableCellView and added a red color for the background in order to see if the NSZeroRect gets automatically updated to the current cell rect - it does work. But it just doesn't make sense to create a subview of NSTableCellView with a zero-frame... is there a method inside NSTableCellView I should subclass and position the NSTextField? Or is it common to get the frame inside -viewForTableColumn and adjusting the text field there? What's the way Apple had in mind concerning programmatically creating a view-based NSTableView? I couldn't find a lot of information on this, the demo video on developer.apple.com directly uses an NSTextField as the return cell-view but my view needs to be more complex than that. I am pretty sure I just missed something very important here. ;-) And my second question is - is it possible to create a cell view which is bigger than one row, thus it's overlaying other rows (I'm not customizing my table view to death, I have a good reason for cell views being positioned over several rows).
