Today's the day for (yet) another blog post over on
gtkDcoding.com and the subjects are:
- the RadioButton, and
- the ColorButton.
You can find it here:

Thank you!
But if we want one of the others to be active on start-up, as
well as syncing up the observed object, we have to call that
button’s setActive(true) function. To simplify this two-step
process, I broke it out into its own function,
setActiveButton().
The function ignores its argument and always uses member variable
button2 instead. Changing the parameter type to MyRadioButton and
using 'button' instead of 'button2' in the body works, so you
could pass another default in RadioBox.this().
Can somebody explain why getRgba() (apparently inherited from
ColorChooser) does take an out parameter instead of returning an
Gdk.RGBA?
