Detail
The ColorSelection is a widget that is used to select a color. It consists of a color wheel and number of sliders and entry boxes for color parameters such as hue, saturation, value, red, green, blue, and opacity. It is found on the standard color selection dialog box ColorSelectionDialog.

Constructors
colorSelectionNew :: IO ColorSelection
Creates a new ColorSelection.
Methods
colorSelectionGetCurrentAlpha
:: ColorSelectionClass self
=> self
-> IO Intreturns an integer between 0 and 65535.
Returns the current alpha value.
colorSelectionSetCurrentAlpha
:: ColorSelectionClass self
=> self
-> Intalpha - an integer between 0 and 65535.
-> IO ()
Sets the current opacity to be alpha. The first time this is called, it will also set the original opacity to be alpha too.
colorSelectionGetCurrentColor :: ColorSelectionClass self => self -> IO Color
Gets the current color in the ColorSelection widget.
colorSelectionSetCurrentColor
:: ColorSelectionClass self
=> self
-> Colorcolor - A Color to set the current color with.
-> IO ()
Sets the current color to be color. The first time this is called, it will also set the original color to be color too.
colorSelectionGetHasOpacityControl
:: ColorSelectionClass self
=> self
-> IO Boolreturns True if the color selector has an opacity control. False if it does't.
Determines whether the ColorSelection widget has an opacity control.
colorSelectionSetHasOpacityControl
:: ColorSelectionClass self
=> self
-> BoolhasOpacity - True if color selector can set the opacity, False otherwise.
-> IO ()
Sets the ColorSelection widget to use or not use opacity.
colorSelectionGetHasPalette
:: ColorSelectionClass self
=> self
-> IO Boolreturns True if the selector has a palette. False if it hasn't.
Determines whether the color selector has a color palette.
colorSelectionSetHasPalette
:: ColorSelectionClass self
=> self
-> BoolhasPalette - True if palette is to be visible, False otherwise.
-> IO ()
Sets whether to show or hide the palette.
colorSelectionGetPreviousAlpha
:: ColorSelectionClass self
=> self
-> IO Intreturns an integer between 0 and 65535.
Returns the previous alpha value.
colorSelectionSetPreviousAlpha
:: ColorSelectionClass self
=> self
-> Intalpha - an integer between 0 and 65535.
-> IO ()
Sets the 'previous' alpha to be alpha. This function should be called with some hesitations, as it might seem confusing to have that alpha change.
colorSelectionGetPreviousColor :: ColorSelectionClass self => self -> IO Color
Returns the original color value.
colorSelectionSetPreviousColor :: ColorSelectionClass self => self -> Color -> IO ()
Sets the 'previous' color to be color. This function should be called with some hesitations, as it might seem confusing to have that color change. Calling colorSelectionSetCurrentColor will also set this color the first time it is called.
colorSelectionIsAdjusting :: ColorSelectionClass self => self -> IO Bool
Gets the current state of the widget. Returns True if the user is currently dragging a color around, and False if the selection has stopped.
Attributes
colorSelectionHasOpacityControl :: ColorSelectionClass self => Attr self Bool

Whether the color selector should allow setting opacity.

Default value: False

colorSelectionHasPalette :: ColorSelectionClass self => Attr self Bool

Whether a palette should be used.

Default value: False

colorSelectionCurrentAlpha :: ColorSelectionClass self => Attr self Int

The current opacity value (0 fully transparent, 65535 fully opaque).

Allowed values: <= 65535

Default value: 65535

colorSelectionPreviousAlpha :: ColorSelectionClass self => Attr self Int
'previousAlpha' property. See colorSelectionGetPreviousAlpha and colorSelectionSetPreviousAlpha
