Struct ColorChooser

pub struct ColorChooser { /* private fields */ }

👎Deprecated: Since 4.10

Use ColorDialog and ColorDialogButton instead of widgets implementing ColorChooser ColorChooser is an interface that is implemented by widgets for choosing colors.

Depending on the situation, colors may be allowed to have alpha (translucency).

In GTK, the main widgets that implement this interface are ColorChooserWidget, ColorChooserDialog and ColorButton.

Properties

rgba

The currently selected color, as a gdk::RGBA struct.

The property can be set to change the current selection programmatically.

Readable | Writeable

use-alpha

Whether colors may have alpha (translucency).

When ::use-alpha is false, the gdk::RGBA struct obtained via the rgba property will be forced to have alpha == 1.

Implementations are expected to show alpha by rendering the color over a non-uniform background (like a checkerboard pattern).

Readable | Writeable

Signals

color-activated

Emitted when a color is activated from the color chooser.

This usually happens when the user clicks a color swatch, or a color is selected and the user presses one of the keys Space, Shift+Space, Return or Enter.

Implements

ColorChooserExt, ColorChooserExtManual

GLib type: GObject with reference counted clone semantics.

Trait Implementations

impl Clone for ColorChooser

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 ColorChooser

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

Formats the value using the given formatter.

impl HasParamSpec for ColorChooser

type ParamSpec = ParamSpecObject

type SetValue = ColorChooser

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ColorChooser

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<T: ColorChooserImpl> IsImplementable<T> for ColorChooser

fn interface_init(iface: &mut Interface<Self>)

Override the virtual methods of this interface for the given subclass and do other interface initialization.

fn instance_init(_instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for ColorChooser

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<OT: ObjectType> PartialEq<OT> for ColorChooser

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 ColorChooser

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 ColorChooser

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for ColorChooser

impl IsA<ColorChooser> for ColorButton

impl IsA<ColorChooser> for ColorChooserDialog

impl IsA<ColorChooser> for ColorChooserWidget
