QNavitCtl - Navit Bookmarks via dbus

Hi Ed,

to build it on your PC, you need to have qmake (from Qt) installed.
Then simply run
#qmake
(the name may differ, liket qmake-qt4 or something)
This will create your Makefile, then simply run
#make
and you are done, you will get one binary called "qnavitcl" - that's it.

If you want to build for your Openmoko phone, use my bitbake recipe here (simply copy to your OE tree) and it will build the package for you.

If you want a prebuilt binary - get it from here [1] (you'll also get dependencies from there). It is built for SHR-U.

Have you enabled dbus in navit.xml? This is essential.

Use dbus-send to get a navit instance and then you can control it through the path you get back. Have a look at [2] how I did it in Qt:
registerNavitInstance() and setCenter() will be of most interest for you.

If you use dbus-send, you also need to print the replies - otherwise you cannot use them ;-) - see man page for futher details

BUT - with current version of navit I could not get it to work as the dbus interface seems to have changed - "iter" does not exist anymore and I have not found a way yet to get an instance and set destination :(

Cheers,
 Christian
