Description
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.

getColor
Arguments
| :: (HasCallStack, MonadIO m, IsHSV a) | |
| => a |
|
| -> 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
Arguments
| :: (HasCallStack, MonadIO m, IsHSV a) | |
| => a |
|
| -> m (Int32, Int32) |
Queries the size and ring width of an HSV color selector.
Since: 2.14
isAdjusting
Arguments
| :: (HasCallStack, MonadIO m, IsHSV a) | |
| => a |
|
| -> m Bool | Returns: |
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
Arguments
| :: (HasCallStack, MonadIO m) | |
| => m HSV | Returns: A newly-created HSV color selector. |
Creates a new HSV color selector.

| :: (HasCallStack, MonadIO m, IsHSV a) | |
| => a |
|
| -> Double |
|
| -> Double |
|
| -> Double |
|
| -> 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
Arguments
| :: (HasCallStack, MonadIO m, IsHSV a) | |
| => a |
|
| -> Int32 |

toRgb
Arguments
| :: (HasCallStack, MonadIO m) | |

Signals
changed
type HSVChangedCallback = IO () Source #
No description available in the introspection data.
afterHSVChanged :: (IsHSV a, MonadIO m) => a -> ((?self :: a) => HSVChangedCallback) -> m SignalHandlerId Source #
Connect a signal handler for the changed signal, to be run after the default handler. When overloading is enabled, this is equivalent to
after hSV #changed callback
By default the object invoking the signal is not passed to the callback.
If you need to access it, you can use the implit ?self parameter.
Note that this requires activating the ImplicitParams GHC extension.
onHSVChanged :: (IsHSV a, MonadIO m) => a -> ((?self :: a) => HSVChangedCallback) -> m SignalHandlerId Source #
Connect a signal handler for the changed signal, to be run before the default handler. When overloading is enabled, this is equivalent to
on hSV #changed callback
move
type HSVMoveCallback = DirectionType -> IO () Source #
No description available in the introspection data.
afterHSVMove :: (IsHSV a, MonadIO m) => a -> ((?self :: a) => HSVMoveCallback) -> m SignalHandlerId Source #
Connect a signal handler for the move signal, to be run after the default handler. When overloading is enabled, this is equivalent to
after hSV #move callback
By default the object invoking the signal is not passed to the callback.
If you need to access it, you can use the implit ?self parameter.
Note that this requires activating the ImplicitParams GHC extension.
onHSVMove :: (IsHSV a, MonadIO m) => a -> ((?self :: a) => HSVMoveCallback) -> m SignalHandlerId Source #
Connect a signal handler for the move signal, to be run before the default handler. When overloading is enabled, this is equivalent to
on hSV #move callback
