Hi Jon,
Without seeing more of your code, the problem might be as simple as
the fact that you need to add the radio buttons to some container that
has been added to the window. So either Root.get().add() all your
buttons, or add them all to something like a panel and then add the
panel in the same way. If this is the problem, check out the widget
gallery radiobutton example and click on the source code tab:
http://gwt.google.com/samples/Showcase/Showcase.html#CwRadioButton
If that wasn't the problem, perhaps it's in the way you're
instantiating the radiobuttons? If you have, say, an array of their
labels you've gotten dynamically per question and a container
VerticalPanel:
String[] buttonnames = {"there", "their", "they're"};
VerticalPanel vPanel = new VerticalPanel();
The code should be as simple as
RadioButton[] arby = new RadioButton[buttonnames.length];
for(int i = 0; i < buttonnames.length; i++) {
arby[i] = new RadioButton(groupName, buttonnames[i]);
vPanel.add(arby[i]);
}
Then just add vPanel to the window so you can see it.
Root.get().add(vPanel);
Hope this helps and I'm not completely off base interpreting your
problem!
