GI.GstVideo.Objects.ColorBalanceChannel
Description
The ColorBalanceChannel object represents a parameter
for modifying the color balance implemented by an element providing the
ColorBalance interface. For example, Hue or Saturation.
Synopsis
- newtype ColorBalanceChannel = ColorBalanceChannel (ManagedPtr ColorBalanceChannel)
- class (GObject o, IsDescendantOf ColorBalanceChannel o) => IsColorBalanceChannel o
- toColorBalanceChannel :: (MonadIO m, IsColorBalanceChannel o) => o -> m ColorBalanceChannel
- type ColorBalanceChannelValueChangedCallback = Int32 -> IO ()
- afterColorBalanceChannelValueChanged :: (IsColorBalanceChannel a, MonadIO m) => a -> ((?self :: a) => ColorBalanceChannelValueChangedCallback) -> m SignalHandlerId
- onColorBalanceChannelValueChanged :: (IsColorBalanceChannel a, MonadIO m) => a -> ((?self :: a) => ColorBalanceChannelValueChangedCallback) -> m SignalHandlerId
Exported types
newtype ColorBalanceChannel Source #
Memory-managed wrapper type.
Constructors
| ColorBalanceChannel (ManagedPtr ColorBalanceChannel) |
Instances
class (GObject o, IsDescendantOf ColorBalanceChannel o) => IsColorBalanceChannel o Source #
Type class for types which can be safely cast to ColorBalanceChannel, for instance with toColorBalanceChannel.
Instances
| (GObject o, IsDescendantOf ColorBalanceChannel o) => IsColorBalanceChannel o Source # | |
Defined in GI.GstVideo.Objects.ColorBalanceChannel | |
toColorBalanceChannel :: (MonadIO m, IsColorBalanceChannel o) => o -> m ColorBalanceChannel Source #
Cast to ColorBalanceChannel, for types for which this is known to be safe. For general casts, use castTo.

Signals
valueChanged
type ColorBalanceChannelValueChangedCallback Source #
Fired when the value of the indicated channel has changed.
afterColorBalanceChannelValueChanged :: (IsColorBalanceChannel a, MonadIO m) => a -> ((?self :: a) => ColorBalanceChannelValueChangedCallback) -> m SignalHandlerId Source #
Connect a signal handler for the valueChanged signal, to be run after the default handler. When overloading is enabled, this is equivalent to
after colorBalanceChannel #valueChanged 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.
onColorBalanceChannelValueChanged :: (IsColorBalanceChannel a, MonadIO m) => a -> ((?self :: a) => ColorBalanceChannelValueChangedCallback) -> m SignalHandlerId Source #
Connect a signal handler for the valueChanged signal, to be run before the default handler. When overloading is enabled, this is equivalent to
on colorBalanceChannel #valueChanged callback
