Doesn't this print a warning to console?
Your list store has only one column, which therefore gets
number 0, and here you are trying to bind some renderer
attribute to (nonexistent) column 1.
gtk_tree_view_append_column (GTK_TREE_VIEW (main_window_treeview1), column);
gtk_main();
return 0;
}
So... I can't see the result of:
gtk_list_store_set (main_window_list, &iter,
0, "TESTING",
-1);
It's not being listed in the treeview after building / running the code.
Probably a consequence of the problem above -- the tree view
has not actually got anything to display.
