      java.lang.Object getValue()
      Gets the current object array.
      boolean isPaintable()
      Returns true to indicate that we can paint a representation of the string array.
      static void main​(java.lang.String[] args)
      Tests out the array editor from the command line.

      Removes a PropertyChangeListener.
      void setAsText​(java.lang.String text)
      Returns null as we don't support getting/setting values as text.
      void setValue​(java.lang.Object o)
      Sets the current object array.
