Hello everyone,

I use GtkColorButton in preference dialog of this submitted extension:
https://extensions.gnome.org/extension/674/yawl-yet-another-window-list/

I just updated from Gnome 3.6.0 to Gnome 3.6.3 and realized that
GtkColorButton does not work as expected anymore.

After digging around I found that these lines of code that worked fine
in Gjs in Gnome 3.6.0 do not work in Gnome 3.6.3:

let rgba = new Gdk.RGBA();
gtkColorButton.get_rgba(rgba);


What works in 3.6.3 now is:

let rgba = gtkColorButton.get_rgba();


In the former we pass reference to an already existing variable for the
function to modify it, and in the latter the function returns new value.
According to DevHelp the first is what you would use in C, and this is
why I had that in the code, and it worked. On the other hand, I
understand (and saw that all over Gjs) that in Gjs it is common to
return a value instead of passing a reference to an existing variable,
even if there is already another value being returned. For example, in C
Gio::DataInputStream::read_line returns a string and updates its length
by reference, while in Gjs it returns an array containing both the
string and its length.

I cannot verify at the moment if the new second version of code (the one
I need for 3.6.3) will work in 3.6.0. If I knew that the second version
would work in all 3.6.*, I would just stick to it. But I only know that
the first worked in 3.6.0 but not in 3.6.3, and the second works in 3.6.3.

So, my question is: is there any way to make the code consistent with
both versions? Or, maybe, someone could confirm that the second version
works in 3.6.0 (Ubuntu 12.10) as well?

Thanks in advance,
Vadim.
