Detailed Description
A widget used to choose from a list of items.
A ComboBox is a widget that allows the user to choose from a list of valid choices. The ComboBox displays the selected choice. When activated, the ComboBox displays a popup which allows the user to make a new choice. The style in which the selected value is displayed, and the style of the popup is determined by the current theme. It may be similar to a Windows-style combo box.
The ComboBox uses the model-view pattern; the list of valid choices is specified in the form of a tree model, and the display of the choices can be adapted to the data in the model by using cell renderers, as you would in a tree view. This is possible since ComboBox implements the CellLayout interface. The tree model holding the valid choices is not restricted to a flat list, it can be a real tree, and the popup will reflect the tree structure.
To allow the user to enter values not in the model, the 'has-entry' property allows the ComboBox to contain a Gtk::Entry. This entry can be accessed by calling get_entry(), or you can just call get_entry_text() to get the text from the Entry.
For a simple list of textual choices, the model-view API of ComboBox can be a bit overwhelming. In this case, ComboBoxText offers a simple alternative. Both ComboBox and ComboBoxText can contain an entry.
- Deprecated:
- 4.10: Use Gtk::DropDown instead.

Flags: Run Last
Emitted to allow changing how the text in a combo box's entry is displayed.
See property_has_entry().
Connect a signal handler which returns an allocated string representing path. That string will then be used to set the text in the combo box's entry. The default signal handler uses the text from the property_entry_text_column() model column.
Here's an example signal handler which fetches data from the model and displays it in the entry.
