It's strange cos I have added columns!
partial code:
.....
for (i = 0; i < 19; i++)
{
cell = gtk_cell_renderer_text_new ();
column = gtk_tree_view_column_new_with_attributes(name_fields[i],
cell, "text", i, NULL);
gtk_tree_view_column_set_resizable(GTK_TREE_VIEW_COLUMN(column),
TRUE);
gtk_tree_view_append_column(GTK_TREE_VIEW(view), column);
}
gtk_widget_show (view);
......
Thanks,
France
