GI.Gdk.Structs.Color
Contents
Description
A #GdkColor is used to describe a color, similar to the XColor struct used in the X11 drawing API.
- newtype Color = Color (ForeignPtr Color)
- newZeroColor :: MonadIO m => m Color
- noColor :: Maybe Color
- data ColorCopyMethodInfo
- colorCopy :: MonadIO m => Color -> m Color
- data ColorEqualMethodInfo
- colorEqual :: MonadIO m => Color -> Color -> m Bool
- data ColorFreeMethodInfo
- colorFree :: MonadIO m => Color -> m ()
- data ColorHashMethodInfo
- colorHash :: MonadIO m => Color -> m Word32
- colorParse :: MonadIO m => Text -> m (Bool, Color)
- data ColorToStringMethodInfo
- colorToString :: MonadIO m => Color -> m Text
- colorReadBlue :: Color -> IO Word16
- colorReadGreen :: Color -> IO Word16
- colorReadPixel :: Color -> IO Word32
- colorReadRed :: Color -> IO Word16
