Signals

colorChanged

type C_ColorSelectionColorChangedCallback = Ptr () -> Ptr () -> IO ()

This signal is emitted when the color changes in the ColorSelection according to its update policy.

afterColorSelectionColorChanged :: (IsColorSelection a, MonadIO m) => a -> ColorSelectionColorChangedCallback -> m SignalHandlerId

after colorSelection #colorChanged callback

genClosure_ColorSelectionColorChanged :: MonadIO m => ColorSelectionColorChangedCallback -> m (GClosure C_ColorSelectionColorChangedCallback)

Wrap the callback into a GClosure.

mk_ColorSelectionColorChangedCallback :: C_ColorSelectionColorChangedCallback -> IO (FunPtr C_ColorSelectionColorChangedCallback)
