Thank you!
You're welcome. :)
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().
Thanks for catching my typos. I gotta stop messing with the code
once it's working. :) Fixes are uploaded.
Anyway, you can also declare it as a RadioButton and that works,
too... as long as the variables inside the function are changed
to 'button.'
Can somebody explain why getRgba() (apparently inherited from
ColorChooser) does take an out parameter instead of returning
an Gdk.RGBA?
My understanding is this:
Returning an object (as opposed to a single value) means
returning a pointer rather than the entire object. And the object
will cease to exist once the function returns because the scope
no longer exists. So, it follows that an out variable passed in
will preserve the object itself once program control returns to
the caller.
