set classic interface in Gtk.colorbutton

[rastersoft <raster rastersoft com>]

Hi all:

I'm using a Gtk.ColorButton in an app to set a color, but I need it to 
have alpha value. The problem is that the new ColorChooser interface is 
confusing for the users, because, by default, it shows just a list of 
opaque colors and they have to click the "+" button and then it shows 
the classic interface to select a color with transparency. Is it 
possible to show by default that classic interface, or, at least, to add 
a transparency slide in the main interface?

Thanks.
