swt单选按钮的通用侦听器

Question

I'm developing a SWT app and in one particular form there are 14 pairs of Yes-No radio buttons. Each of these pairs have a text box associated with them. So if a user selects Yes, the associated textbox should be editable else uneditable. I find writing 28 listeners for the radio buttons really daunting. Since the radio buttons have nothing much to do than just rendering the textbox editable/uneditable I was hoping if there were some generic type of listeners in SWT that would be applicable to a set of radio buttons specified in an array or like that. Are there any frameworks or shall I have to write individual listeners?

Edit
I'm trying to fire an event only when the radio button is selected

rdoExperience.addListener(SWT.CHECK, new RadioButtonSelection( txtExperience));

but SWT.CHECK is causing the event to be fired on mouse hover over radio button too. I've tried using SWT.SELECTED too but it's not working either and I can't find other suitable SWT constants. W;hat should I use?

Answer 1

Good point. Sorry I don't know such thing.

However, you create one yourself: Instead of writing an anonymous listener for every button, you could write one - say MyButtonListener - and give it the button text box as an argument. Than you instantiate MyButtonListener with the appropriate text box as an argument. Than in the Listeners appropriate callback method you enable or disable the text box.

Edit: My bad. Of course I meant you could give it your text box like radioBtn.addListener(SWT.SELECTED, new MyButtonListener(textfield1));

Answer 2

You could create one SelectionListener and add it to each of the radio buttons. Then you can ascertain which button was pressed from the selection event and map that to a text box. For the mapping you could use an array or hashtable.
