Method Detail

connect

public void connect(RadioGroup.GroupToggled handler)
Hook up a handler to the RadioGroup.GroupToggled signal.

Since:

getActive

public Object getActive()
Indicate which RadioAction or Radio widget in this RadioGroup is currently selected active.

This will return null if no RadioAction or Radio widget is selected, but note that this is generally indicative of something wrong with the programming; generally a RadioGroup should always have at least one RadioAction or Radio widget selected.
