Hi all!

I'm trying to implement my first MIDlets in eSWT. However I find a lot of examples that contain an instance of SelectionAdapter. The question is what can I put in its place in order to get my code working in MIDP emulators?

Please provide an alternative for the following sample piece of code:

c1.addSelectionListener(new SelectionAdapter() {
      public void widgetSelected(SelectionEvent e) {
        if (c1.getText().equals("Item One")) {
          String newItems[] = { "A", "B", "C" };
          c2.setItems(newItems);
          c2.setEnabled(true);
        } else if (c1.getText().equals("Item Two")) {
          String newItems[] = { "A", "B", "C" };
          c2.setItems(newItems);
          c2.setEnabled(true);
        } else {
          c2.add("Not Applicable");
          c2.setText("Not Applicable");
        }
      }
    });

Thanks for your time!

A selection adapter just provides default implmentations of widgetSelected
and widgetDefaultSelected that do nothing. It saves you from having to write
"public void widgetDefaultSelected(SelectionEvent e) {}".
