/**

* SECTION:gtkcombobox
|
|
* @Short_description: A widget used to choose from a list of items
|
|
* @Title: GtkComboBox
|
|
* @See_also: #GtkComboBoxText, #GtkTreeModel, #GtkCellRenderer
|
|
*
|
|
* A GtkComboBox is a widget that allows the user to choose from a list of
|
|
* valid choices. The GtkComboBox displays the selected choice. When
|
|
* activated, the GtkComboBox 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 GtkComboBox 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 GtkComboBox implements the
|
|
* #GtkCellLayout 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.
|
|
*
|
|
* For a simple list of textual choices, the model-view API of GtkComboBox
|
|
* can be a bit overwhelming. In this case, #GtkComboBoxText offers a
|
|
* simple alternative.
