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.

Methods
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.
Since: 2.14
setColor
Arguments
| :: (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 |
|
| -> Int32 |
|
| -> m () |
Sets the size and ring width of an HSV color selector.
Since: 2.14
toRgb
Arguments
| :: (HasCallStack, MonadIO m) | |
| => Double |
|
| -> Double |
|
| -> Double |
|
| -> 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
Signals
changed
type C_HSVChangedCallback = Ptr () -> Ptr () -> IO () Source #
Type for the callback on the (unwrapped) C side.
type HSVChangedCallback = IO () Source #
No description available in the introspection data.
afterHSVChanged :: (IsHSV a, MonadIO m) => 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
genClosure_HSVChanged :: HSVChangedCallback -> IO Closure Source #
Wrap the callback into a Closure.
mk_HSVChangedCallback :: C_HSVChangedCallback -> IO (FunPtr C_HSVChangedCallback) Source #
Generate a function pointer callable from C code, from a C_HSVChangedCallback.
noHSVChangedCallback :: Maybe HSVChangedCallback Source #
A convenience synonym for Nothing :: Maybe HSVChangedCallback
onHSVChanged :: (IsHSV a, MonadIO m) => 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
wrap_HSVChangedCallback :: HSVChangedCallback -> C_HSVChangedCallback Source #
Wrap a HSVChangedCallback into a C_HSVChangedCallback.
move
type C_HSVMoveCallback = Ptr () -> CUInt -> Ptr () -> IO () Source #
Type for the callback on the (unwrapped) C side.
type HSVMoveCallback = DirectionType -> IO () Source #
No description available in the introspection data.
afterHSVMove :: (IsHSV a, MonadIO m) => 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
genClosure_HSVMove :: HSVMoveCallback -> IO Closure Source #
Wrap the callback into a Closure.
mk_HSVMoveCallback :: C_HSVMoveCallback -> IO (FunPtr C_HSVMoveCallback) Source #
Generate a function pointer callable from C code, from a C_HSVMoveCallback.
noHSVMoveCallback :: Maybe HSVMoveCallback Source #
A convenience synonym for Nothing :: Maybe HSVMoveCallback
onHSVMove :: (IsHSV a, MonadIO m) => 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
wrap_HSVMoveCallback :: HSVMoveCallback -> C_HSVMoveCallback Source #
