This is supported on crate feature v3_20 only.

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.

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.

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.
