In order to hide the complexities of using some of the widgets, php-gtk
sometimes provide certain convenience methods to make it easier to use. In
the case of GtkComboBox, these methods include append_text() ,
prepend_text() , insert_text() and remove_text().

However, when you want to do more advanced stuff, such as changing the
options on-the-fly, you need to access its underlying model directly.

A GtkComboBox is just like a GtkTreeView. It adopts the data-view model. The
data is stored is a data model (e.g. GtkListStore), and the associating view
displays the data.

The following example shows the basic setup using the data-view model for
combobox:

And the following example expands on the above example to show how to change
the options on the fly:
