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`.

Methods
colorSelectionGetCurrentAlpha
:: ColorSelectionClass self |
=> self |
-> IO Int | returns an integer between 0 and 65535.
Returns the current alpha value.
colorSelectionSetCurrentAlpha
:: ColorSelectionClass self |
=> self |
-> Int | `alpha` - 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 |
-> Color | `color` - 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 Bool | returns `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 |
-> Bool | `hasOpacity` - `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 Bool | returns `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 |
-> Bool | `hasPalette` - `True` if palette is to be visible, `False` otherwise.
-> IO () |
Sets whether to show or hide the palette.
colorSelectionGetPreviousAlpha
:: ColorSelectionClass self |
=> self |
-> IO Int | returns an integer between 0 and 65535.
Returns the previous alpha value.
colorSelectionSetPreviousAlpha
:: ColorSelectionClass self |
=> self |
-> Int | `alpha` - 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`
