title: ImageJ dialog path
body: <p>I have a Dialog asking for Preferences, in this Dialog I would like to aks for a path. I'm doing this: Dialog.addString("Saving directory", directory);
  ... I'm asking for lot more.</p>
  
  <p>but I would like to have open up a new window, where you can search the path, like with this command but with more questions and answers in the Dialog.
  path = File.openDialog("Select a File");</p>
  
  <p>thank you</p>
