You might want to take a look at getting a Pango::Layout on the text
that is rendered. Once you have the layout, you can then get a list of
the attributes applied to the text and then you can modify the
foreground color attribute. Once this is accomplished, you can
re-apply the attributes to the layout. See the docs for detail on how
to use Pango.

I've had a look at the mailinglist archive, but only found
an example of setting individual cell background.
This I did get to work, but when I try to adapt it to change foreground
color nothing happens: all text stays black.
Could this have something to do with gtk styles?
This is what I do now:
-----------------------------------------------
Gtk::CellRendererText* cell_renderer;
expModelPtr pModel =
expModelPtr::cast_dynamic(pView->get_model());
vector<Gtk::TreeViewColumn*> columns =
pView->get_columns();
for(vector<Gtk::TreeViewColumn*>::iterator iter =
columns.begin(); iter != columns.end(); iter++)
{
cell_renderer =
dynamic_cast<Gtk::CellRendererText*>((*iter)->get_first_cell_renderer());
(*iter)->add_attribute(cell_renderer->property_foreground(),
pModel->colrecord.m_col_color);
};
-----------------------------------------------
This method works with a Gtk::CellRenderer* and
property_cell_background().
The TreeView only contains text columns, so according to the api
reference, dynamic_cast<Gtk::CellRendererText*>() should work.
Any ideas?
