[ruby-gnome2-devel-en] TreeView returning a COPY of my renderer?

[Eric C. <rub...@an...>]

Hi:

I'm writing an API to handle treeviews, and listviews.  I'm having a
problem with subclassing renderers.  I subclassed
Gtk::CellRendererToggle, and I'm trying to give it "radio" button
functionality:

class VR_CellRendererToggle < Gtk::CellRendererToggle

attr_accessor :radiox

def initialize
  @radiox = false
end

end

This works fine.  I create an instance of it and append() the column to
my treeview.  The problem occurs when I try to retrieve it, and set the
"radio" instance variable to true:

@view.columns(CHECK_BOXES).cellrenderers[0].radiox = true

This has no effect because the renderer in the above statement returns a
copy of the renderer.  I've verified this by showing each object's
object_id on the screen.  They don't match.

Is this how its supposed to work?  What can I do?

Thanks,
Eric
