The normal way to bring a JFileChooser is with the dialog creation utilities.
However, since a JFileChooser is a JComponent, it can just as easily be embedded
in a container. When this is done, it will oftentimes be the case that the
developer will want control of any control buttons (ok, cancel, other) and not
want the default Accept and Cancel buttons to appear. The following property
will allow the developer to specify if the control buttons should be shown
or not by the file chooser.
