Struct EnumList 

pub struct EnumList { /* private fields */ }

A [gio::ListModel][crate::gio::ListModel] representing values of a given enum.

EnumList contains objects of type EnumListItem.

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

⚠️ The following code is in c ⚠️

choices = gtk_drop_down_new (G_LIST_MODEL (gtk_enum_list_new (type)),
                             gtk_property_expression_new (GTK_TYPE_ENUM_LIST_ITEM,
                                                          NULL,
                                                          "nick"));

Implements

[trait@glib::ObjectExt], [trait@gio::prelude::ListModelExt]

GLib type: GObject with reference counted clone semantics.

Implementations

impl EnumList

pub fn new(enum_type: Type) -> EnumList

Creates a new EnumList for @enum_type.

enum_type

the type of the enum to construct the model from

Returns

the newly created EnumList

pub fn find(&self, value: i32) -> u32

Finds the position of a given enum value in @self.

If the value is not found, Gtk::INVALID_LIST_POSITION is returned.

value

an enum value

Returns

the position of the value

pub fn enum_type(&self) -> Type

Gets the type of the enum represented by @self.

Returns

the enum type

Trait Implementations

impl Clone for EnumList

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EnumList

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for EnumList

impl HasParamSpec for EnumList

type ParamSpec = ParamSpecObject

type SetValue = EnumList

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str) -> ParamSpecObjectBuilder<'_, EnumList>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for EnumList

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IsA<ListModel> for EnumList

impl Ord for EnumList

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl ParentClassIs for EnumList

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for EnumList

fn eq(&self, other: &OT) -> bool

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for EnumList

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for EnumList

fn static_type() -> Type

Returns the type identifier of Self.
