Re: Two events when selecting a RadioButton

[lecas malecas <darkiiiiii gmail com>]

Couldn't find that thread.. but yes, I can check for the state of the
button to see which one is active. thanks!

Ok, getting the two events may be useful in some cases, but then we
should have two separated signals, one for just the one that was
activated, and another as it is now.

Ok, it could have some uses, but I think it should be a separated event then
