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.

static SlotChangePaletteHook Gtk::ColorSelection::set_change_palette_hook ( const SlotChangePaletteHook slot) [static]
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:
alphaAn 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:
colorA Gdk::Color to set the current color with.
void Gtk::ColorSelection::set_current_rgba ( const Gdk::RGBA color)
void Gtk::ColorSelection::set_has_opacity_control ( bool  has_opacity = true)

Sets the colorsel to use or not use opacity.

Parameters:
has_opacitytrue 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_palettetrue 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:
alphaAn 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:
colorA Gdk::Color to set the previous color with.
void Gtk::ColorSelection::set_previous_rgba ( const Gdk::RGBA color)
Glib::SignalProxy0< void > Gtk::ColorSelection::signal_color_changed ( )
Prototype:
void on_my_color_changed()
