Quickies for NSControl

---

General

• Changing checkbox toggle state [permalink]
  [myCheckbox setState: NSOffState]

  NSOnState also works.

• Respond to every keystroke in a textfield [permalink]
  Make your object a delegate of the textfield, and add this NSControl delegate method:
  

  - (void) controlTextDidChange: (NSNotification *) notification
  {
      // do work here, like count the characters or something
  } // controlTextDidBeginEditing
