Interface

GtkColorChooser

Description [src] 

interface Gtk.ColorChooser : GObject.Object

GtkColorChooser is an interface that is implemented by widgets for choosing colors. Depending on the situation, colors may be allowed to have alpha (translucency).

In GTK+, the main widgets that implement this interface are GtkColorChooserWidget, GtkColorChooserDialog and GtkColorButton.

Available since:3.4

Prerequisite

In order to implement ColorChooser, your type must inherit from GObject.

Instance methods

gtk_color_chooser_add_palette

Adds a palette to the color chooser. If orientation is horizontal, the colors are grouped in rows, with colors_per_line colors in each row. If horizontal is FALSE, the colors are grouped in columns instead.

Available since: 3.4

gtk_color_chooser_get_rgba

Gets the currently-selected color.

Available since: 3.4

gtk_color_chooser_get_use_alpha

Returns whether the color chooser shows the alpha channel.

Available since: 3.4

gtk_color_chooser_set_rgba

Sets the color.

Available since: 3.4

gtk_color_chooser_set_use_alpha

Sets whether or not the color chooser should use the alpha channel.

Available since: 3.4

Properties

Gtk.ColorChooser:rgba

The ::rgba property contains the currently selected color, as a GdkRGBA struct. The property can be set to change the current selection programmatically.

Available since: 3.4

Gtk.ColorChooser:use-alpha

When ::use-alpha is TRUE, colors may have alpha (translucency) information. When it is FALSE, the GdkRGBA struct obtained via the GtkColorChooser:rgba property will be forced to have alpha == 1.

Available since: 3.4

Signals

Gtk.ColorChooser::color-activated

Emitted when a color is activated from the color chooser. This usually happens when the user clicks a color swatch, or a color is selected and the user presses one of the keys Space, Shift+Space, Return or Enter.

Available since: 3.4
