* @See_also: #GtkFontButton
*
* The #GtkColorButton is a button which displays the currently selected
2014-12-30 12:46:11 +00:00
* 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 #GtkButton, it gets the .color style class.
