Detailed Description

A Gio::ListModel representing values of a given enum.

Gtk::EnumList contains objects of type Gtk::EnumListItem.

A simple way to use a Gtk::EnumList is to populate a Gtk::DropDown widget using the short name (or "nick") of the values of an enumeration type:

GType enum_type = Glib::Value<Gtk::Justification>::value_type(); // an example
Glib::RefPtr<Gtk::EnumList> enum_list = Gtk::EnumList::create(enum_type);
Glib::RefPtr<Gtk::PropertyExpression> expression =
Gtk::DropDown* drop_down = Gtk::make_managed<Gtk::DropDown>(enum_list, expression);
Choose an item from a list.
Definition dropdown.h:74
static GType get_type()
Get the GType for this class, for use with the underlying GObject type system.
static Glib::RefPtr< EnumList > create(GType enum_type)
Creates a new Gtk::EnumList for enum_type.
static Glib::RefPtr< PropertyExpression > create(GType this_type, const Glib::ustring &property_name)
Creates an expression that looks up a property via the this argument.
auto make_managed(T_Args &&... args)
Create a Gtk::Object such as a widget and Gtk::manage() it in a single step.
Definition object.h:67

All variables in the code snippet can be declared auto. The full types are shown to make it clear what they are.

Member Function Documentation

◆ create()

Glib::RefPtr< EnumList > Gtk::EnumList::create ( GType enum_type)
static

Creates a new Gtk::EnumList for enum_type.

Since gtkmm 4.24
Parameters
enum_typeThe type of the enum to construct the model from.
Returns
The newly created Gtk::EnumList.

◆ find()

unsigned int Gtk::EnumList::find ( int value) const

Finds the position of a given enum value in this EnumList.

If the value is not found, GTK_INVALID_LIST_POSITION is returned.

Since gtkmm 4.24
Parameters
valueAn enum value. If the enum is an enum class, use static_cast<int>(value) to convert the value to an int.
Returns
The position of the value.

◆ get_enum_type()

GType Gtk::EnumList::get_enum_type ( ) const

Gets the type of the enum represented by self.

Since gtkmm 4.24
Returns
The enum type.

◆ get_type()

GType Gtk::EnumList::get_type ( )
static

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

◆ gobj() [1/2]

GtkEnumList * Gtk::EnumList::gobj ( )
inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GtkEnumList * Gtk::EnumList::gobj ( ) const
inline

Provides access to the underlying C GObject.

◆ gobj_copy()

GtkEnumList * Gtk::EnumList::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

◆ operator=()

EnumList & Gtk::EnumList::operator= ( EnumList && src)
noexcept

◆ property_enum_type()

Glib::PropertyProxy_ReadOnly< GType > Gtk::EnumList::property_enum_type ( ) const

The type of the enum represented by the model.

Since gtkmm 4.24
Returns
A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_item_type()

Glib::PropertyProxy_ReadOnly< GType > Gtk::EnumList::property_item_type ( ) const

The type of the items.

See Gio::ListModel::get_item_type().

Since gtkmm 4.24
Returns
A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_n_items()

Glib::PropertyProxy_ReadOnly< unsigned int > Gtk::EnumList::property_n_items ( ) const

The number of items.

See Gio::ListModel::get_n_items().

Since gtkmm 4.24

Default value: 0

Returns
A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ wrap()

Glib::RefPtr< Gtk::EnumList > wrap ( GtkEnumList * object,
bool take_copy = false )
related

A Glib::wrap() method for this object.

Parameters
objectThe C instance.
take_copyFalse if the result should take ownership of the C instance. True if it should take a new copy or ref.
Returns
A C++ instance that wraps this C instance.
