Properties

alpha

The selected opacity value (0 fully transparent, 65535 fully opaque).

Since: 2.4

constructColorButtonAlpha :: IsColorButton o => Word32 -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “alpha” property. This is rarely needed directly, but it is used by new.

getColorButtonAlpha :: (MonadIO m, IsColorButton o) => o -> m Word32

Get the value of the “alpha” property. When overloading is enabled, this is equivalent to

get colorButton #alpha

setColorButtonAlpha :: (MonadIO m, IsColorButton o) => o -> Word32 -> m ()

Set the value of the “alpha” property. When overloading is enabled, this is equivalent to

set colorButton [ #alpha := value ]

color

The selected color.

Since: 2.4

constructColorButtonColor :: IsColorButton o => Color -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “color” property. This is rarely needed directly, but it is used by new.

getColorButtonColor :: (MonadIO m, IsColorButton o) => o -> m (Maybe Color)

Get the value of the “color” property. When overloading is enabled, this is equivalent to

get colorButton #color

setColorButtonColor :: (MonadIO m, IsColorButton o) => o -> Color -> m ()

Set the value of the “color” property. When overloading is enabled, this is equivalent to

set colorButton [ #color := value ]

rgba

The RGBA color.

Since: 3.0

clearColorButtonRgba :: (MonadIO m, IsColorButton o) => o -> m ()

Set the value of the “rgba” property to Nothing. When overloading is enabled, this is equivalent to

clear #rgba

constructColorButtonRgba :: IsColorButton o => RGBA -> IO (GValueConstruct o)

This property should be used in cases where the palette in the editor would be redundant, such as when the color button is already part of a palette.

Since: 3.20

constructColorButtonShowEditor :: IsColorButton o => Bool -> IO (GValueConstruct o)

Since: 2.4

constructColorButtonUseAlpha :: IsColorButton o => Bool -> IO (GValueConstruct o)

Signals

colorSet

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

Type for the callback on the (unwrapped) C side.

type ColorButtonColorSetCallback = IO ()

The ::color-set signal is emitted when the user selects a color. When handling this signal, use gtk_color_button_get_rgba() to find out which color was just selected.

Note that this signal is only emitted when the user changes the color. If you need to react to programmatic color changes as well, use the notify::color signal.

Since: 2.4

afterColorButtonColorSet :: (IsColorButton a, MonadIO m) => a -> ColorButtonColorSetCallback -> m SignalHandlerId

Connect a signal handler for the “color-set” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after colorButton #colorSet callback

genClosure_ColorButtonColorSet :: MonadIO m => ColorButtonColorSetCallback -> m (GClosure C_ColorButtonColorSetCallback)

Wrap the callback into a GClosure.

mk_ColorButtonColorSetCallback :: C_ColorButtonColorSetCallback -> IO (FunPtr C_ColorButtonColorSetCallback)

Generate a function pointer callable from C code, from a C_ColorButtonColorSetCallback.

noColorButtonColorSetCallback :: Maybe ColorButtonColorSetCallback

A convenience synonym for Nothing :: Maybe ColorButtonColorSetCallback.

onColorButtonColorSet :: (IsColorButton a, MonadIO m) => a -> ColorButtonColorSetCallback -> m SignalHandlerId

Connect a signal handler for the “color-set” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on colorButton #colorSet callback

wrap_ColorButtonColorSetCallback :: ColorButtonColorSetCallback -> C_ColorButtonColorSetCallback

Wrap a ColorButtonColorSetCallback into a C_ColorButtonColorSetCallback.
