Ok. Your current GtkTreeView must be something like this:
GtkTreeStore *store = gtk_tree_store_new (1, G_TYPE_STRING);
GtkTreeView *view = gtk_tree_view_new_with_model (GTK_TREE_MODEL (store));
gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW (view),
0, "header", gtk_cell_renderer_text_new(), "text", 0, NULL);
Now, modify that into this:
GtkTreeStore *store = gtk_tree_store_new (2, G_TYPE_STRING, GDK_TYPE_COLOR);
GtkTreeView *view = gtk_tree_view_new_with_model (GTK_TREE_MODEL (store));
gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW (view),
0, "header", gtk_cell_renderer_text_new(), "text", 0,
"foreground-gdk", 1, NULL);
Check the changes... I bet you'll understand... Anyway, a GtkTreeView is made
of several components... What displays the several items text is not it, but
a GtkCellRendererText. And what tells a CellRenderer about the values it
should use is the GtkTreeViewColumn. Check the code again...
A bit complex, but you can do complex things in return. ;)
This GtkTreeView tutoral seems very good. Check it:
http://scentric.net/tutorial/
Btw, instead of the "foreground-gdk", you may want to use the "foreground"
attribute where a string is asked (like "brown"). These attributes are the
ones from GtkCellRendererText. Check them.
And you may set the color value to NULL if you want to use the default. As an
example:
GdkColor red = { 0, 255, 0, 0, 0 };
gtk_tree_store_append (getStore(), &iter, parent);
gtk_tree_store_set (getStore(), &iter, 0, "red", 1, &color, -1);
gtk_tree_store_append (getStore(), &iter, parent);
gtk_tree_store_set (getStore(), &iter, 0, "default color", -1);
Cheers,
Ricardo
