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.
