I'm Requesting for comments about this solution to release/distribute/package Queen BeeCon Widgets inside debian-package.

Issues are described here:
http://wiki.maemo.org/Queen_BeeCon_W...ipts_please.3F

So far I have made first debian-package and pushed it to the extas-devel.
WARNING: It can ruin your working widgets (during installation, upgrading or removing). I have not installed it on my primary phone myself!
Package name is qbw-harmattan-date

With apt-get source qbw-harmattan-date you can get all files.
(http://maemo.org/packages/view/qbw-harmattan-date/)

I will describe how it is made so it can be analysed and potential failing parts could be spotted.
I'm using unmodified queen-beecon, but it can be tuned, if something can be then done more robust way.


I will use name HarmattanDate for this instructions. Name can't contain spaces or dashes.

-------
So...
You have good widget on your phone. Export it to the file (exported_widget.txt).
copy file "/var/lib/gconf/apps/osso/hildon-desktop/applets/XXX/%gconf.xml" (conf.xml) where XXX is something like queen-beecon.desktop-0. This file contains coordinates for widget.


on debian/rules:install
Code:
	mkdir -p $(CURDIR)/debian/qbw-harmattan-date/var/lib/gconf/apps/osso/hildon-desktop/applets/queen-beecon.desktop-HarmattanDate
	cp conf.xml $(CURDIR)/debian/qbw-harmattan-date/var/lib/gconf/apps/osso/hildon-desktop/applets/queen-beecon.desktop-HarmattanDate/%gconf.xml

	mkdir -p $(CURDIR)/debian/qbw-harmattan-date/opt/qbw-harmattan-date/
	cp exported_widget.txt $(CURDIR)/debian/qbw-harmattan-date/opt/qbw-harmattan-date/exported_widget

	#Optional: Add to another desktops also (tune also postinst/postrm)
	mkdir -p $(CURDIR)/debian/qbw-harmattan-date/var/lib/gconf/apps/osso/hildon-desktop/applets/queen-beecon.desktop-HarmattanDate2

Package will contain some files, and postinstallation/postrm are used for adding/deleting widget (or widgets, if many desktops are used). Removing package (i.e. running postrm) should be possible (and safe) even widget (or some of them) is reconfigured by user, or even manually removed.
