That would be great indeed :)

So i have the renderer bound to the column globally set as 'renderTime'.
Global is good in this case because of testing :)

Every 300ms I have a function with the iteration called via a timeout.
I'm getting the GtkListStore out of the GtkTreeView and clear it.

slotlist = (GtkWidget*)g_object_get_data(G_OBJECT(window),
                                           "slotlist");
store = GTK_LIST_STORE(
        gtk_tree_view_get_model(GTK_TREE_VIEW(slotlist)));
gtk_list_store_clear(store);

while(databaseresult) {

        if( age > 4) {
                g_object_set(G_OBJECT(renderTime),"background","red",NULL);
        } else {
                g_object_set(G_OBJECT(renderTime),"background","red",NULL);
        }
        gtk_list_store_append(store, &iter);
        gtk_list_store_set(....);
}

See? I think I got it all wrong with the renderer stuff anyway :)
Weird, append and then set.. I just saw.. Shouldn't that be first set
and then append?

It works all fine btw, that list.. except for everytime the function is
called, the memory piles up.. And I spend hours debugging.. but that is
another matter.

Great, but I guess I'm going to write that renderer myself somehow.. But
I will need some directions in doing so :/

Thanks!
