void gtk_color_selection_set_use_opacity (GtkColorSelection *colorsel, gboolean use_opacity); |
Sets the colorsel to use or not use opacity.
gboolean gtk_color_selection_get_use_opacity (GtkColorSelection *colorsel); |
Determines whether the colorsel can use opacity.
void gtk_color_selection_set_use_palette (GtkColorSelection *colorsel, gboolean use_palette); |
Shows and hides the palette based upon the value of use_palette.
gboolean gtk_color_selection_get_use_palette (GtkColorSelection *colorsel); |
Determines whether the palette is used.
void gtk_color_selection_set_color (GtkColorSelection *colorsel, gdouble *color); |
Sets the current color to be color. The first time this is called, it will also set the original color to be color too.

void gtk_color_selection_get_color (GtkColorSelection *colorsel, gdouble *color); |
Sets color to be the current color in the GtkColorSelection widget.
Retrieve the currently selected color value.
void gtk_color_selection_set_old_color (GtkColorSelection *colorsel, gdouble *color); |
void gtk_color_selection_get_old_color (GtkColorSelection *colorsel, gdouble *color); |

void gtk_color_selection_set_palette_color (GtkColorSelection *colorsel, gint x, gint y, gdouble *color); |
Set the palette located at (x, y) to have color set as its color.
gboolean gtk_color_selection_get_palette_color (GtkColorSelection *colorsel, gint x, gint y, gdouble *color); |
Set color to have the color found in the palette located at (x, y). If the palette is unset, it will leave the color unset.
void gtk_color_selection_unset_palette_color (GtkColorSelection *colorsel, gint x, gint y); |
Change the palette located at (x, y) to have no color set.
gboolean gtk_color_selection_is_adjusting (GtkColorSelection *colorsel); |
