Struct IconTheme 

pub struct IconTheme { /* private fields */ }

message); g_error_free (error); } else { // Use the pixbuf g_object_unref (pixbuf); } ]|

Signals

changed

Emitted when the current icon theme is switched or GTK+ detects that a change has occurred in the contents of the current icon theme.

Implements

IconThemeExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

Implementations

impl IconTheme

pub const NONE: Option<&'static IconTheme> = None

pub fn new() -> IconTheme

Creates a new icon theme object. Icon theme objects are used to lookup up an icon by name in a particular icon theme. Usually, you’ll want to use default() or for_screen() rather than creating a new icon theme object for scratch.

Returns

the newly created IconTheme object.

pub fn default() -> Option<IconTheme>

Gets the icon theme for the default screen. See for_screen().

Returns

A unique IconTheme associated with the default screen. This icon theme is associated with the screen and can be used as long as the screen is open. Do not ref or unref it.

pub fn for_screen(screen: &Screen) -> Option<IconTheme>

Gets the icon theme object associated with screen; if this function has not previously been called for the given screen, a new icon theme object will be created and associated with the screen. Icon theme objects are fairly expensive to create, so using this function is usually a better choice than calling than new() and setting the screen yourself; by using this function a single icon theme object will be shared between users.

screen

a gdk::Screen

Returns

A unique IconTheme associated with the given screen. This icon theme is associated with the screen and can be used as long as the screen is open. Do not ref or unref it.

Trait Implementations

impl Clone for IconTheme

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 IconTheme

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

Formats the value using the given formatter.

impl Default for IconTheme

fn default() -> Self

Returns the “default value” for a type.

impl Eq for IconTheme

impl HasParamSpec for IconTheme

type ParamSpec = ParamSpecObject

type SetValue = IconTheme

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for IconTheme

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 Ord for IconTheme

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 IconTheme

type Parent = Object

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

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

Inequality operator !=.

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

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 IconTheme

fn static_type() -> Type

Returns the type identifier of Self.
