Signals
The default signal is "color-set", emitted when the user selects a colour.
The "file-changed" signal is emitted if file-monitor is true and the input file being monitored has changed.
The following signals are connected-up for all widgets:
button-press-event, button-release-event, configure-event, enter-notify-event, leave-notify-event, focus-in-event, focus-out-event, hide, show, key-press-event, key-release-event, map-event, unmap-event

The following general functions can be performed by any widget capable of emitting signals:
Type | Description | Parameter | Since |

Notes
1. Setting the "use-alpha" tag attribute to true will enable alpha selection. Alpha can be passed in following the #rrggbb value separated by a '| ' character, or via the "alpha" tag attribute. Although the colour selection dialog displays alpha as an 8bit 0-255 value, GTK+ and Gtkdialog manage it as a 16bit 0-65535 value and therefore it'll require converting between the two formats. To convert from 8bit to 16bit use alpha * 257 and from 16bit to 8bit use (alpha + 257 / 2) / 257 .
This widget was introduced in version 0.7.21.
