Color() [2/2]

zrythm::utils::Color::Color

(

std::string_view

hex

)

Construct a new Color object by parsing a hex color string.

Parameters

hex	Hex color string (e.g., "#ff5588" or "#ff5588cc")

Member Function Documentation

from_hex()

Color zrythm::utils::Color::from_hex ( std::string_view hex )

static

Parses a hex color string using QColor.

Supports QColor-compatible formats: #RGB, #RRGGBB Alpha defaults to 1.0.

Parameters

hex	Hex color string (e.g., "#ff5588")

Returns

Color Parsed color

get_arranger_object_color()

Color zrythm::utils::Color::get_arranger_object_color ( const Color & color, bool is_hovered, bool is_selected, bool is_transient, bool is_muted )

static

Gets the color the widget should be.

Parameters

color	The original color.
is_selected	Whether the widget is supposed to be selected or not.

get_mid_color()

Color zrythm::utils::Color::get_mid_color ( const Color & c1, const Color & c2, const float transition = 0.5f )

static

Returns the color in-between two colors.

Parameters

transition

How far to transition (0.5 for half).

morph()

Color zrythm::utils::Color::morph ( const Color & other, float amt ) const

nodiscard

Morphs from this color to another, depending on the given amount.

Eg, if amt is 0, the resulting color will be this color. If amt is 1, the resulting color will be other.

rgb_to_hex()

std::string zrythm::utils::Color::rgb_to_hex ( float r, float g, float b )

static

Converts RGB float values to a hex string.

Parameters

r	Red (0.0-1.0)
g	Green (0.0-1.0)
b	Blue (0.0-1.0)

Returns

std::string Hex color string (e.g., "#ff5588")

to_hex()

std::string zrythm::utils::Color::to_hex

(

)

const

Converts the color to a hex string (RGB only).

Returns

std::string Hex color string (e.g., "#ff5588")
