GI.Gtk.Interfaces.ColorChooser

ColorChooser is an interface that is implemented by widgets for choosing colors. Depending on the situation, colors may be allowed to have alpha (translucency).

In GTK+, the main widgets that implement this interface are ColorChooserWidget, ColorChooserDialog and ColorButton.

Methods

overloadedMethod :: MethodProxy ColorChooserAddPaletteMethodInfo a -> signature -> s

colorChooserAddPalette

Arguments

:: (HasCallStack, MonadIO m, IsColorChooser a)

=> a

chooser: a ColorChooser

-> Orientation

orientation: OrientationHorizontal if the palette should be displayed in rows, OrientationVertical for columns

-> Int32

colorsPerLine: the number of colors to show in each row/column

-> Maybe [RGBA]

colors: the colors of the palette, or Nothing

-> m ()

Adds a palette to the color chooser. If orientation is horizontal, the colors are grouped in rows, with colorsPerLine colors in each row. If horizontal is False, the colors are grouped in columns instead.

The default color palette of ColorChooserWidget has 27 colors, organized in columns of 3 colors. The default gray palette has 9 grays in a single row.

The layout of the color chooser widget works best when the palettes have 9-10 columns.

Calling this function for the first time has the side effect of removing the default color and gray palettes from the color chooser.

If colors is Nothing, removes all previously added palettes.
