## Detailed Description

A widget used to select a color.

This widget is used to select a color. It consists of a color wheel and number of sliders and entry boxes for color parameters such as hue, saturation, value, red, green, blue, and opacity.

It is found on the standard color selection dialog box Gtk::ColorSelectionDialog.

void Gtk::ColorSelection::set_current_alpha | ( | guint16 | 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.

Parameters

  alpha | An integer between 0 and 65535.

void Gtk::ColorSelection::set_current_color | ( | const Gdk::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.

Parameters

  color | A Gdk::Color to set the current color with.

void Gtk::ColorSelection::set_has_opacity_control | ( | bool | has_opacity = `true` | ) |

Sets the colorsel to use or not use opacity.

Parameters

  has_opacity | `true` if colorsel can set the opacity, `false` otherwise.

void Gtk::ColorSelection::set_has_palette | ( | bool | has_palette = `true` | ) |

Shows and hides the palette based upon the value of has_palette.

Parameters

  has_palette | `true` if palette is to be visible, `false` otherwise.

void Gtk::ColorSelection::set_previous_alpha | ( | guint16 | 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.

Parameters

  alpha | An integer between 0 and 65535.

void Gtk::ColorSelection::set_previous_color | ( | const Gdk::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.

Parameters

  color | A Gdk::Color to set the previous color with.

Glib::SignalProxy< void > Gtk::ColorSelection::signal_color_changed | ( |  | ) |

Slot Prototype:
  `void on_my_color_changed()`
