RE: [ULC-developer] finding the amount of buttons in a ULCButtonGroup

[Janak Mulani]

Hi Chris,

ULCButtonGroup's API is different from Swing's ButtonGroup API.

There is already an issue: http://www.canoo.com/jira/browse/UBA-716

You can implement the method by extending ULCButtonGroup and ULCRadioButton
(or a concrete toggle button type) as shown in the snippet at the end of
this mail.

Thanks and regards,

Janak
