GI.Gtk.Objects.ColorButton

The ColorButton is a button which displays the currently selected color and allows to open a color selection dialog to change the color. It is suitable widget for selecting a color in a preference dialog.

CSS nodes

GtkColorButton has a single CSS node with name button. To differentiate it from a plain Button, it gets the .color style class.

Properties

alpha

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

Since: 2.4

constructColorButtonAlpha :: (IsColorButton o, MonadIO m) => Word32 -> m (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, MonadIO m) => Color -> m (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, MonadIO m) => RGBA -> m (GValueConstruct o)

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

getColorButtonRgba :: (MonadIO m, IsColorButton o) => o -> m (Maybe RGBA)

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

get colorButton #rgba

setColorButtonRgba :: (MonadIO m, IsColorButton o) => o -> RGBA -> m ()

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

set colorButton [ #rgba := value ]

showEditor

Set this property to True to skip the palette in the dialog and go directly to the color editor.

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, MonadIO m) => Bool -> m (GValueConstruct o)

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

getColorButtonShowEditor :: (MonadIO m, IsColorButton o) => o -> m Bool

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

get colorButton #showEditor

setColorButtonShowEditor :: (MonadIO m, IsColorButton o) => o -> Bool -> m ()

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

set colorButton [ #showEditor := value ]

title

The title of the color selection dialog

Since: 2.4

constructColorButtonTitle :: (IsColorButton o, MonadIO m) => Text -> m (GValueConstruct o)

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

getColorButtonTitle :: (MonadIO m, IsColorButton o) => o -> m Text

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

get colorButton #title

setColorButtonTitle :: (MonadIO m, IsColorButton o) => o -> Text -> m ()

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

set colorButton [ #title := value ]

useAlpha

If this property is set to True, the color swatch on the button is rendered against a checkerboard background to show its opacity and the opacity slider is displayed in the color selection dialog.

Since: 2.4

constructColorButtonUseAlpha :: (IsColorButton o, MonadIO m) => Bool -> m (GValueConstruct o)

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

getColorButtonUseAlpha :: (MonadIO m, IsColorButton o) => o -> m Bool

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

get colorButton #useAlpha

setColorButtonUseAlpha :: (MonadIO m, IsColorButton o) => o -> Bool -> m ()

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

set colorButton [ #useAlpha := value ]

Signals

colorSet

type ColorButtonColorSetCallback = IO ()

The colorSet 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 notifycolor signal.

Since: 2.4

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

Connect a signal handler for the colorSet signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after colorButton #colorSet 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.

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

Connect a signal handler for the colorSet signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on colorButton #colorSet callback
