GtkWidget* gnome_color_picker_new (void); |
Creates a new GNOME color picker widget. This returns a widget in the form of a small button containing a swatch representing the current selected color. When the button is clicked, a color-selection dialog will open, allowing the user to select a color. The swatch will be updated to reflect the new color when the user finishes.
void gnome_color_picker_set_d (GnomeColorPicker *cp, gdouble r, gdouble g, gdouble b, gdouble a); |
Set color shown in the color picker widget using floating point values.
void gnome_color_picker_get_d (GnomeColorPicker *cp, gdouble *r, gdouble *g, gdouble *b, gdouble *a); |
Retrieve color currently selected in the color picker widget in the form of floating point values.

r : | Output location of red color component, values are in [0.0, 1.0] |
g : | Output location of green color component, values are in [0.0, 1.0] |
b : | Output location of blue color component, values are in [0.0, 1.0] |
a : | Output location of alpha color component, values are in [0.0, 1.0] |
void gnome_color_picker_set_i8 (GnomeColorPicker *cp, guint8 r, guint8 g, guint8 b, guint8 a); |
Set color shown in the color picker widget using 8-bit integer values.
void gnome_color_picker_get_i8 (GnomeColorPicker *cp, guint8 *r, guint8 *g, guint8 *b, guint8 *a); |

void gnome_color_picker_set_dither (GnomeColorPicker *cp, gboolean dither); |
Sets whether the picker should dither the color sample or just paint a solid rectangle.
gboolean gnome_color_picker_get_dither (GnomeColorPicker *cp); |
Does the picker dither the color sample or just paint a solid rectangle.
void gnome_color_picker_set_use_alpha (GnomeColorPicker *cp, gboolean use_alpha); |
Sets whether or not the picker should use the alpha channel.
gboolean gnome_color_picker_get_use_alpha (GnomeColorPicker *cp); |
