Re: adding and removing LabeledColorWidget

Hi John,

visad/benjamin/Galaxy.java does this successfully, with code:

  widget_panel.remove(lw2)
  widget_panel.add(lw5, 0);

where lw2 and lw5 are LabeledColorWidgets. This is only slightly
different from your code, but perhaps that is the critical
difference.

Good luck,
Bill
