Properties:

• public uint current_alpha { set; get; }
• public Color current_color { set; get; }
• public bool has_opacity_control { set; get; }
• public bool has_palette { set; get; }

Static methods:

• public static bool palette_from_string (string str, Color[] colors)
  Parses a color palette string; the string is a colon-separated list of color names readable by parse.
• public static unowned string palette_to_string (Color[] colors)
  Encodes a palette as a string, useful for persistent storage.
• public static weak ColorSelectionChangePaletteWithScreenFunc set_change_palette_with_screen_hook (ColorSelectionChangePaletteWithScreenFunc func)
  Installs a global function to be called whenever the user tries to modify the palette in a color selection. This function should save the new palette contents, and update the GtkSettings property "gtk-color-palette" so all GtkColorSelection widgets will be modified.

Creation methods:

• public ColorSelection ()
  Creates a new GtkColorSelection.

Methods:

• public uint16 get_current_alpha ()
  Returns the current alpha value.
• public void get_current_color (out Color color)
  Sets color to be the current color in the GtkColorSelection widget.
• public bool get_has_opacity_control ()
  Determines whether the colorsel has an opacity control.
• public bool get_has_palette ()
  Determines whether the color selector has a color palette.
• public uint16 get_previous_alpha ()
  Returns the previous alpha value.
• public void get_previous_color (out Color color)
  Fills color in with the original color value.
• public bool is_adjusting ()
  Gets the current state of the colorsel.
• public void set_current_alpha (uint16 alpha)
  Sets the current opacity to be alpha. The first time this is called, it will also set the original opacity to be alpha too.
• public void set_current_color (Color 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.
• public void set_has_opacity_control (bool has_opacity)
  Sets the colorsel to use or not use opacity.
• public void set_has_palette (bool has_palette)
  Shows and hides the palette based upon the value of has_palette.
• public void set_previous_alpha (uint16 alpha)
  Sets the 'previous' alpha to be alpha. This function should be called with some hesitations, as it might seem confusing to have that alpha change.
• public void set_previous_color (Color color)
  Sets the 'previous' color to be color. This function should be called with some hesitations, as it might seem confusing to have that color change. Calling set_current_color will also set this color the first time it is called.

Signals:

• public virtual void color_changed ()
