Pango Layouts and Editing

I didn't blog/hack for quite some time now (maybe except some minor bug fixing for some apps from Ubunut Breezy); the last 2 days I happily found time to hack on criawips.

I'm working on the editing stuff now, but I have some issues with to few documentation about using the Pango Layout class. Is there documentation about using the layout for custom widgets/etc. that need to support editing (that means especially stuff like cursor navigation, selections and text insertion)? I find the GtkEntry code very big for example code.

At least my code works now for text which is centered and aligned to the top of a display block. More work for sunday...
