Hi

I created a radio group with 2 buttons (Yes/No)
Now depending which button is selected a field needs to change color.

I tried the following Listener (full code attached):

      tropicamideGroup.addListener(SWT.Selection, new Listener()
      {
         public void handleEvent(Event event)
         {
            switch (tropicamideGroup.getSelectionIndex())
            {
               case 0:
                  txtAuthorized.setBackground(SWTResourceManager.getColor(60, 179, 113));
                  txtAuthorized.setText("\r\nAuthorized");
                  break;
               case 1:
                  txtAuthorized.setBackground(SWTResourceManager.getColor(SWT.COLOR_DARK_RED));
                  txtAuthorized.setText("\r\nNot Authorized");
                  break;
            }
            // recreateAndLayout();
         }
      });

I tried also this version:

      tropicamideGroup.addSelectionListener(new SelectionAdapter()
      {
         @Override
         public void widgetSelected(SelectionEvent e)
         {
            RadioItem[] radioItems = tropicamideGroup.getItems();

            if (radioItems[0].equals(e.item))
            {
               txtAuthorized.setBackground(SWTResourceManager.getColor(60, 179, 113));
               txtAuthorized.setText("\r\nAuthorized");
            }
            if (radioItems[1].equals(e.item))
            {
               txtAuthorized.setBackground(SWTResourceManager.getColor(SWT.COLOR_DARK_RED));
               txtAuthorized.setText("\r\nNot Authorized");
            }
         }

none of them changes the color
what do i do wrong?

Hi Charlie,

Please provide a running snippet with only the minimum code that exposes your problem and I will take a look. I have to do too much work to make your sample code work.

For examples on snippets see http://www.eclipse.org/nebula/snippets.php

Best regards,

Wim

Hi Wim

Thx for the reply. I actually took the listener from the radio example code.
I am currently not at the development machine, but on monday i will put a small dialog with a main() and only the radio group and the text up here for you to have a look at it.

Morning Wim
Looks like it works in this demo.
It seems that when using the quick test, the does not use the listener

I add the short test also for others who might be interested in the solution.
Sort of a snippet..
