Hi Benlau,

Actually, I'm rejoiced to see your library, as I could find very good use for it in my upcoming Sticky Scribble Notes widget.

For color dialog, you could use the SimpleColorDialog found in Hildon-Extras. http://wiki.maemo.org/Hildon-Extras
I actually wrote a Qt wrapper for the Gtk-based parts, so it is dead easy to use it from your lib. (We are currently working on a library release for it, but currently the leader is on vacation... for the moment, we just include its stuff in our projects.)

Is there any information or API doc about your library?
