List of all members.

## Detailed Description

A text entry field with a dropdown list A ComboBoxEntry is a widget that allows the user to choose from a list of valid choices or enter a different value.

It is very similar to a ComboBox, but it displays the selected value in an entry to allow modifying it.

In contrast to a ComboBox, the underlying model of a ComboBoxEntry must always have a text column (see set_text_column()), and the entry will show the content of the text column in the selected row.

See also ComboBoxEntryText, , which is specialised for a single text column.

To add and remove strings from the list, just modify the model using its data manipulation API. You can get the* Entry by using get_child().

The ComboBoxEntry widget looks like this:
