Re: enable/disable widgets?

You really should take a look at the "Known Implementing Classes":

Hello,

I actually needed the functionality in the widget class to let my own
"Form" class enable/disable all its child widgets at the same time.

However, I made this workaround and it's ok for me at the moment:

 public void setEnabled (boolean e)
 {
  Iterator<Widget> itr = grd.iterator (); // grd is a FlexTable which
contains my form controls

  while (itr.hasNext ())
  {
   Widget w = itr.next ();

   if (w instanceof TextBox)
   {
    TextBox t = (TextBox) w;
    t.setEnabled (e);
   }

   if (w instanceof PasswordTextBox)
   {
    PasswordTextBox t = (PasswordTextBox) w;
    t.setEnabled (e);
   }

  ...
  }
 }
