[elbe-devel] [PATCH 05/14] Debianize - Radio buttons widget

[Bastian Germann]

> From: Olivier Dion <dion at linutronix.de>
> 
> Radio buttons can be grouped either vertically (default) or
> horizontally.  This is decided within the ctor with the policy
> variable argument.
> 
> The calle should provides an enumeration type and a member of the

caller

> enumeration type to use by default.
> 
> Signed-off-by: Olivier Dion <dion at linutronix.de>
