RE: incompatible pointer type?

Hi,

I see a couple of errors in your code:

If you want to get the text from first char, second argument should be
0, not 1. ( gtk_editable_get_chars (GTK_EDITABLE(combo, 0, -1); )

To insert a new row, use:  gtk_clist_append (GTK_CLIST (list), text);

Here you return a gnome_app, not the clist (clist1)

Try this:
