gtk:color-button-new-with-rgba (rgba)

rgba -- a gdk:rgba color to set the current color with

The new gtk:color-button widget.

Creates a new color button with the given RGBA color. This returns a widget in the form of a button containing a swatch representing the currently selected color. When the button is clicked, a color chooser dialog will open, allowing the user to select a color. The swatch will be updated to reflect the new color when the user finishes. The gtk:color-button implementation is deprecated since 4.10. Use the gtk:color-dialog-button widget instead.
