## Description

### Note

This widget is available in GTK+ 2.4 and PyGTK 2.4 and above.

The `gtk.ComboBoxEntry` is a replacement for the `gtk.Combo`. The `gtk.ComboBoxEntry` is subclassed from `gtk.ComboBox` and implements the `gtk.CellLayout` interface; refer to their descriptions for a number of useful methods and properties for managing the contents of a combo box entry. A `gtk.ComboBoxEntry` also contains a child `gtk.Entry` accessed by using the child attribute of the combo box entry:

      entry = comboboxentry.child

A `gtk.ComboBoxEntry` is created with the gtk.ComboBoxEntry() constructor. The constructor can also be called with the optional parameters `model` (a `gtk.TreeModel` - default `None`) and `column` (a number of a column in `model` - default 0). If no `gtk.TreeModel` is specified it can be added later with the `set_model`() method. The text column can be changed using the `set_text_column`() method. A new combo box entry is created and packed with a `gtk.CellRendererText` but no attribute mappings are set on the cell renderer.

Alternatively, the `gtk.combo_box_entry_new_text`() function creates a `gtk.ComboBoxEntry` with an associated `gtk.ListStore` model and the text column attribute mapping set to 0. In this combo box entry each list item is a text string that can be selected. The convenience methods `gtk.ComboBox.append_text`(), `gtk.ComboBox.prepend_text`(), `gtk.ComboBox.insert_text`() and `gtk.ComboBox.remove_text`() can be used to manage the contents of the `gtk.ComboBoxEntry`. Using the `gtk.combo_box_entry_new_text`() function is equivalent to:

      liststore = gtk.ListStore(gobject.TYPE_STRING)
      comboboxentry = gtk.ComboBoxEntry(liststore, 0)

## Constructor

        gtk.ComboBoxEntry(model=None, column=-1)

`model` : | The `gtk.TreeModel` to associate with the combo box entry, or `None`
`column` : | The number of the column to use for setting the strings of the combo box entry.
Returns : | A new `gtk.ComboBoxEntry`.

### Note

This constructor is available in PyGTK 2.4 and above.

Creates a new `gtk.ComboBoxEntry` that has a `gtk.Entry` as child and associated with the `gtk.TreeModel` specified by `model` and using the column of `model` specified by `column` to retrieve strings. If `model` was not specified it defaults to `None` but you can change the model using the `gtk.ComboBox.set_model()` method. If `column` was not specified it defaults to -1 meaning the text column is unset but you can change it using the `set_text_column`() method. Once the text column is set either in the constructor or using the `set_text_column`() method it cannot be changed. A ValueError exception is thrown if `column` is outside the range of column numbers for `model`.

## Methods

### gtk.ComboBoxEntry.set_text_column

        def set_text_column(text_column)

`text_column` : | A column in the associated `gtk.TreeModel` to use as the data source for the strings.

### Note

This method is available in PyGTK 2.4 and above.

The `set_text_column`() method sets the "text-column" property to the value of `tree_column` only if the text column has not been set (that is, "text-column" is -1). The value of `tree_column` is the number of the tree model column used as the data source for the strings of the combo box entry.

### gtk.ComboBoxEntry.get_text_column

        def get_text_column()

Returns : | The number of the column in the associated `gtk.TreeModel` used as the data source for the combo box entry.

### Note

This method is available in PyGTK 2.4 and above.

The `get_text_column`() method returns the number of the `gtk.TreeModel` column that is used as the data source for the strings of the combo box entry.

## Functions

### gtk.combo_box_entry_new_text

        def gtk.combo_box_entry_new_text()

Returns : | A new `gtk.ComboBoxEntry` widget.

### Note

This function is available in PyGTK 2.4 and above.

The `gtk.combo_box_entry_new_text`() function is a convenience function which constructs a new `gtk.ComboBoxEntry`, just displaying strings. If you use this function to create a combo box entry, you should only manipulate its `gtk.TreeModel` data source with the following `gtk.ComboBox` convenience methods: `gtk.ComboBox.append_text`(), `gtk.ComboBox.insert_text`(), `gtk.ComboBox.prepend_text`() and `gtk.ComboBox.remove_text`().
