GI.Gtk.Objects.HSV

HSV is the “color wheel” part of a complete color selector widget. It allows to select a color by determining its HSV components in an intuitive way. Moving the selection around the outer ring changes the hue, and moving the selection point inside the inner triangle changes value and saturation.

HSV has been deprecated together with ColorSelection, where it was used.

Methods

getColor

hSVGetColor

Arguments

:: (HasCallStack, MonadIO m, IsHSV a)

=> a

hsv: An HSV color selector

-> m (Double, Double, Double)

Queries the current color in an HSV color selector. Returned values will be in the [0.0, 1.0] range.

Since: 2.14

getMetrics

hSVGetMetrics

Arguments

:: (HasCallStack, MonadIO m, IsHSV a)

=> a

hsv: An HSV color selector

-> m (Int32, Int32)

Queries the size and ring width of an HSV color selector.

Since: 2.14

isAdjusting

hSVIsAdjusting

Arguments

:: (HasCallStack, MonadIO m, IsHSV a)

=> a

hsv: A HSV

-> m Bool

Returns: True if clients can ignore changes to the color value, since they may be transitory, or False if they should consider the color value status to be final.

An HSV color selector can be said to be adjusting if multiple rapid changes are being made to its value, for example, when the user is adjusting the value with the mouse. This function queries whether the HSV color selector is being adjusted or not.

Since: 2.14

new

hSVNew

Arguments

:: (HasCallStack, MonadIO m)

=> m HSV

Returns: A newly-created HSV color selector.

Creates a new HSV color selector.

Since: 2.14

setColor

hSVSetColor

Arguments

:: (HasCallStack, MonadIO m, IsHSV a)

=> a

hsv: An HSV color selector

-> Double

h: Hue

-> Double

s: Saturation

-> Double

v: Value

-> m ()

Sets the current color in an HSV color selector. Color component values must be in the [0.0, 1.0] range.

Since: 2.14

setMetrics

hSVSetMetrics

Arguments

:: (HasCallStack, MonadIO m, IsHSV a)

=> a

hsv: An HSV color selector

-> Int32

size: Diameter for the hue ring

-> Int32

ringWidth: Width of the hue ring

-> m ()

Sets the size and ring width of an HSV color selector.

Since: 2.14

toRgb

hSVToRgb

Arguments

:: (HasCallStack, MonadIO m)

=> Double

h: Hue

-> Double

s: Saturation

-> Double

v: Value

-> m (Double, Double, Double)

Converts a color from HSV space to RGB.

Input values must be in the [0.0, 1.0] range; output values will be in the same range.

Since: 2.14
