example for using the new directory chooser field in generic dialogs in ImageJ

My_DialogWithDirChooser.java

import ij.*;
import ij.gui.*;
import ij.plugin.*;

// requires ImageJ 1.53d8 or later 
public class My_DialogWithDirChooser implements PlugIn {

   String dir;

   public void run(String arg) {
      dir = "empty";
      if (!showDialog()) return;
      IJ.log("you chose: "+dir);
   }

   boolean showDialog() {
      GenericDialog gd = new GenericDialog("Dialog with dir chooser");
      gd.addMessage("\u2606"+" Instructions here !");
      gd.addDirectoryField("dir chooser \u261E", IJ.getDirectory("home"));
      gd.showDialog();
      if (gd.wasCanceled())
         return false;
      dir = gd.getNextString();
      return true;
   }

}

removed the unicode char from label's first word as this is what gets recorded!
run("My DialogWithDirChooser", "dir=/Users/jeromemutterer/");
