Just create your own renderer:
class UserCellRendererColorButton : public CellRenderer
override get_size_vfunc, render_vfunc and add (or reuse from
CellRenderer) properties you will read to draw the button widget (you
will need color value at least).
Inside get_size_vfunc you should set dimensions for ColorButton widget.
Inside render_vfunc you should use method from Gtk::Style that draws
Button (ColorButton) widget.
When creating TreeViewColumn, you should set attribute:
treeColumn->add_attribute( yourRenderer->your_color_property(), yourColumnModel.colorButtonColumn );
Simple, and always works :)
