Array of the item objects.
Array, default = []
The
.items property defines all toolbar items (buttons, drop down menus, etc.) You
can define them during object creation or at run-time.
The structure of the item is defined in
.item_template()
If you change this property during run-time, do not forget to call the
.refresh()
method.
To add/remove items during run-time, you should better call
.add(),
.insert(),
.remove() methods.
