Detailed Description

This is a simple variant of ComboBox that hides the model-view complexity for simple text-only use cases.

You can add items to a ComboBoxText with append(), insert() or prepend() and remove items with remove_text().

If the ComboBoxText contains an entry (via the 'has_entry' property), its contents can be retrieved using get_active_text(). The entry itself can be accessed by calling ComboBox::get_entry() or ComboBox::get_entry_text().

You should not call set_model() or attempt to pack more cells into this combo box via its CellLayout base class.

Deprecated:

4.10: Use Gtk::DropDown with a Gtk::StringList instead.

delete

~ComboBoxText()

Gtk::ComboBoxText::~ComboBoxText ( )

overridenoexcept

ComboBoxText() [3/3]

Gtk::ComboBoxText::ComboBoxText ( bool  has_entry = false )

explicit

Creates a new empty ComboBoxText, optionally with an entry.

Parameters

has_entry

If this is true then this will have an Entry widget.

Member Function Documentation

append() [1/2]

void Gtk::ComboBoxText::append	(	const Glib::ustring &	id,
		const Glib::ustring &	text
	)

Appends text to the list of strings stored in combo_box.

If id is non-nullptr then it is used as the ID of the row.

This is the same as calling insert() with a position of -1.

Deprecated: 4.10: Use Gtk::DropDown

Parameters

id	A string ID for this value.
text	A string.

append() [2/2]

void Gtk::ComboBoxText::append

(

const Glib::ustring &

text

)

Appends text to the list of strings stored in combo_box.

This is the same as calling insert_text() with a position of -1.

Deprecated: 4.10: Use Gtk::DropDown

Parameters

text

A string.

get_active_text()

Glib::ustring Gtk::ComboBoxText::get_active_text

(

)

const

Returns the currently active string in combo_box.

If no row is currently selected, nullptr is returned. If combo_box contains an entry, this function will return its contents (which will not necessarily be an item from the list).

Deprecated: 4.10: Use Gtk::DropDown

Returns

A newly allocated string containing the currently active text.

get_type()

static GType Gtk::ComboBoxText::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

gobj() [1/2]

GtkComboBoxText * Gtk::ComboBoxText::gobj ( )

inline

Provides access to the underlying C GObject.

gobj() [2/2]

const GtkComboBoxText * Gtk::ComboBoxText::gobj ( ) const

void Gtk::ComboBoxText::insert	(	int	position,
		const Glib::ustring &	id,
		const Glib::ustring &	text
	)

If id is non-nullptr then it is used as the ID of the row. See Gtk::ComboBox::property_id_column().

If position is negative then text is appended.

Deprecated: 4.10: Use Gtk::DropDown

Parameters

position	An index to insert text.
id	A string ID for this value.

void Gtk::ComboBoxText::insert	(	int	position,
		const Glib::ustring &	text
	)
