Re: [Gui4j-user] radio buttons grouped

[Kay Krüger-B. <ka...@we...>]

Hi,

I suspect you get an error message somewhat like "mygroup is undefined". That's because syntactically the argument of the group attribute is a method call and therefore gui4j looks for a method definition like
 public void mygroup() {}
in the corresponding controller.

(see http://www.gui4j.org/gui4jdocs/methodCalls.html for the documentation on method call syntax.)

One simple solution in this case is to use the gui4j notation for string constants where syntactically method calls are expected. This notation is to use single quotes (').

Try to change your example to (not the single quotes around mygroup):
 <radioButton guiId="radio1" text="'Active'" group="'mygroup'" />
 <radioButton guiId="radio2" text="'Deleted'" group="'mygroup'" />

Hope it helps.

May I ask what purpose you are using gui4j for? We still use it internally in our company (where gui4j originated) but we had very little feedback from the community after making it open source in 2005.

Thanks,
Kay
