A button to launch a color selection dialog.
The GtkColorButton is a button which displays the currently selected color an allows to open a color selection dialog to change the color. It is suitable widget for selecting a color in a preference dialog.
The ColorButton widget looks like this:
| virtual Gtk::ColorButton::~ColorButton | ( | ) | [virtual] |
| Gtk::ColorButton::ColorButton | ( | ) |
Creates a new color button.
This creates 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.
| Gtk::ColorButton::ColorButton | ( | const Gdk::Color& | color ) | [explicit] |
Creates a new color button with a predefined color.
Same as Gtk::ColorButton::ColorButton(). Additionally takes a Gdk::Color and initializes the button with this color. Equivalent to calling set_color(color) after the default constructor.
| color | A Gdk::Color to set the current color with. |
| guint16 Gtk::ColorButton::get_alpha | ( | ) | const |
| Gdk::Color Gtk::ColorButton::get_color | ( | ) | const |
Returns a copy of the the current color.
Changes to the return value will have no effect on the Gtk::ColorButton.
| Glib::ustring Gtk::ColorButton::get_title | ( | ) | const |
| bool Gtk::ColorButton::get_use_alpha | ( | ) | const |
Does the color selection dialog use the alpha channel?
true if the color sample uses alpha channel, false if not. | const GtkColorButton* Gtk::ColorButton::gobj | ( | ) | const [inline] |
Provides access to the underlying C GtkObject.
Reimplemented from Gtk::Button.
| GtkColorButton* Gtk::ColorButton::gobj | ( | ) | [inline] |

| virtual void Gtk::ColorButton::on_color_set | ( | ) | [protected, virtual] |
| Glib::PropertyProxy<guint16> Gtk::ColorButton::property_alpha | ( | ) |
The selected opacity value (0 fully transparent, 65535 fully opaque).
You rarely need to use properties because there are get_ and set_ methods for almost all of them.
| Glib::PropertyProxy_ReadOnly<guint16> Gtk::ColorButton::property_alpha | ( | ) | const |
The selected opacity value (0 fully transparent, 65535 fully opaque).
You rarely need to use properties because there are get_ and set_ methods for almost all of them.
| Glib::PropertyProxy_ReadOnly<Gdk::Color> Gtk::ColorButton::property_color | ( | ) | const |

| void Gtk::ColorButton::set_alpha | ( | guint16 | alpha ) |
Sets the current opacity to be alpha.
| alpha | An integer between 0 and 65535. |
| void Gtk::ColorButton::set_color | ( | const Gdk::Color& | color ) |
Sets the current color to be color.
| color | A Gdk::Color to set the current color with. |
| void Gtk::ColorButton::set_title | ( | const Glib::ustring & | title ) |
Sets the title for the color selection dialog.
| title | String containing new window title. |
| void Gtk::ColorButton::set_use_alpha | ( | bool | use_alpha = true ) |
Sets whether or not the color button should use the alpha channel.
| use_alpha | true if color button should use alpha channel, false if not. |
| Glib::SignalProxy0< void > Gtk::ColorButton::signal_color_set | ( | ) |
The color_set signal is emitted when the user selects a color.
When handling this signal, use get_color() and get_alpha() to find out which color was just selected.
void on_my_color_set() | Gtk::ColorButton* wrap | ( | GtkColorButton * | object, |
| bool | take_copy = false |
||
| ) | [related] |
A Glib::wrap() method for this object.
| object | The C instance. |
| take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
