title: pop up style dialog
body: <p>I have a pop up button that is loaded with 5 options programicically, if a particular option is selected, lets say, "append the end of file name",then my update function needs to cause a small pop up window with a textField and a save and cancel button to appear. I don't know how to do this.
  I was able to get a nice NSAlert example to work but it does not take a textField that I know of.
  Is there a dialog class or some other modal I should be using or should I be trying to create a second nib? in either case I don't really know how to do it so a good example or tutorial would be great.</p>
  
  <p>Thanks</p>
