I think Xamarin.Mac is not support NSComboBoxDelegate.
How can i catch "comboboxSelectionDidChange"?
You can use the WeakDelegate property. e.g.
myComboBox.WeakDelegate = new Delegate();
private class Delegate : NSObject
// - (void)comboBoxSelectionDidChange:(NSNotification *)notification
public void SelectionDidChange(NSNotification notification)
var sender = notification.Object as NSComboBox;
it works. thank you once again!
