"Selected State Event" for Button or StatefulCanvas

[richip]

Using SmartGWT 5.0p and Firefox 24.0ESR.

Is there an event that a class can listen on that gets triggered when buttons in a RadioGroup change state to "Selected"? Ideally, the event should contain information on which Button went into the selected state and which one lost that state. I looked at all the HasHandlers interfaces in Javadoc and couldn't seem to find one.

For Buttons that are combined into a radioGroup via addToRadioGroup(), there's currently no single handler that you can register to listen across the entire radio group. You need to add a click handler to each Button.

For the similar RadioGroupItem (a FormItem), you can just register a ChangeHandler (as for any FormItem).
