#[repr(C)]
pub struct QColor { /* private fields */ }

Expand description

The QColor class provides colors based on RGB, HSV or CMYK values.

Note that we only expose RGB methods for now.

Implementations

source

impl QColor

source

pub fn alpha(&self) -> i32

Returns the alpha color component of this color.

source

impl QColor

source

pub fn blue(&self) -> i32

Returns the blue color component of this color.

source

impl QColor

source

pub fn green(&self) -> i32

Returns the green color component of this color.

source

impl QColor

source

pub fn red(&self) -> i32

Returns the red color component of this color.

source

impl QColor

source

pub fn set_alpha(&mut self, red: i32)

Sets the alpha of this color to alpha. Integer alpha is specified in the range 0-255.

source

impl QColor

source

pub fn set_blue(&mut self, blue: i32)

Sets the blue color component of this color to blue. Integer components are specified in the range 0-255.

source

impl QColor

source

pub fn set_green(&mut self, green: i32)

Sets the green color component of this color to green. Integer components are specified in the range 0-255.

source

impl QColor

source

pub fn set_red(&mut self, red: i32)

Sets the red color component of this color to red. Integer components are specified in the range 0-255.

source

impl QColor

source

pub fn from_rgba(red: i32, green: i32, blue: i32, alpha: i32) -> Self

Constructs a QColor with the RGB value r, g, b, and the alpha-channel (transparency) value of a.

The color is left invalid if any of the arguments are invalid.

Trait Implementations

source

impl Clone for QColor

source

fn clone(&self) -> QColor

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl Default for QColor

source

fn default() -> Self

Constructs an invalid color. An invalid color is a color that is not properly set up for the underlying window system.

The alpha value of an invalid color is unspecified.

source

impl ExternType for QColor

type Id = (Q, C, o, l, o, r)

A type-level representation of the type’s C++ namespace and type name. Read more

type Kind = Trivial

Either cxx::kind::Opaque or cxx::kind::Trivial. Read more

source

impl From<&QColor> for QVariant

source

fn from(value: &QColor) -> Self

Constructs a QVariant from a reference of $typeName
