Instead of a TableView I want to use a NSTableCellView inside a custom view. So I created a xib file with a standard NSTableCellView and loaded that into a view.
The table cell view is displayed as expected. But I can't make its textfield the first responder. It's not responding to mouse events and it's not even reacting when I explicitly make it the first responder. makeFirstResponder returns true, but I see no blinking cursor and it doesn't respond to any key events.
Adding a regular textfield to the view does work however.
class ViewController: NSViewController
{
@IBOutlet var myView: NSView!
@IBOutlet var cellView: NSTableCellView! //ViewController is the file owner of the xib file
override func viewDidLoad()
{
super.viewDidLoad()
NSBundle(forClass: ViewController.self).loadNibNamed("Cell", owner: self, topLevelObjects: nil)
myview.addSubview(cellView)
cellView.layer?.borderColor = Color.blackColor().CGColor
cellView.layer?.borderWidth = 1
}
override func mouseDown(event: NSEvent)
{
let result = self.view.window?.makeFirstResponder(cellView.textField!)
print(result) //prints true
}
Why am I doing this? Well, I am trying to understand how a view-based table view would be implemented. It seems that at its core a tableview is just a view with lots of (probably cached and reused?) subviews. Also, I always thought that the number of views was limited for efficiency purposes on OS X?
