Playing around with MeeGo Touch

While the MeeGo Touch Python Bindings are still not packaged and released, I though I'd give the C++ library a try and have a look through the class hierarchy. After getting the basic "Hello World" app running, I decided to create an application that can load the list of subscriptions from gPodder's SQLite database:

This view uses MContentItem, which already provides an icon and two lines of text - correctly styled and ready to go. Menu and toolbar items are MAction objects that can either appear everywhere or only at specific places (e.g. only in the toolbar). The great thing is that this all works on your Desktop in a normal window, so testing applications on your computer will be much easier with MeeGo Touch than it is with Hildon (which does not really run without its own hildon-desktop session in Xephyr).

The screenshot above is from the prototype written in C++, and shows how a gPodder MeeGo UI could look like. The MeeGo Touch UI of gPodder will be implemented in Python once the bindings are ready - the framework seems to be fun to work with so far. If you would like to play around with it yourself: MeeGo Touch is available from the MeeGo PPA of Ville M. Vainio if you are on Ubuntu and don't want to build it yourself.

MaemoPad+ ported to Desktop Linux

Some weeks ago, a user of MaemoPad+ asked me if it was possible to port MaemoPad+ to the Desktop, so users of Tablet PCs can make use of it. Apart from that, this can also be useful for users of MaePad to copy their "memos.db" file from the N900 to their PC and edit the file (or just view the contents) on the big screen. The file format used by both MaemoPad+ and MaePad is the same, so users of the mobile versions can share their database files with the Desktop version (and vice versa), which by the way looks like this at the moment:

Most of the Maemo 4 libraries are readily available in Debian (hildon, libosso, hildon-icons, etc..), so the initial port has not been too difficult, even though proper Desktop integration obviously needs more work, and there are some ugly crashers still hidden inside the code ;)

I wonder if it's possible to also package Maemo 5 libraries (Hildon 2.2, etc..) for Debian and upload them to the Debian repositories - this should make it easier to port Maemo 5 applications to the Linux Desktop without having to re-write the whole UI layer. Another cool thing would be to have Hildon 2.2 for Diablo, which would allow us to "backport" Maemo 5 apps to Maemo 4 - again, without the work of having to re-write the UI.

Packages for Ubuntu are available from the MaemoPad+ PPA, and the source is available via Git. Please send backtraces of crashes or (even better!) patches against the "desktop" branch in the Git repo.

HOWTO: Stable Xephyr on Ubuntu 9.04 for Fremantle SDK

As stated in the Fremantle SDK Installation Notes, Xephyr on Ubuntu 9.04 crashes when clicking on a text field in the Fremantle Beta SDK. It also says that the Intrepid (Ubuntu 8.10) version works better. Here is how you can compile and install Intrepid's Xephyr version:

sudo apt-get build-dep xserver-xephyr
sudo apt-get install build-essential devscripts
dget http://at.archive.ubuntu.com/ubuntu/pool/main/x/xorg-server/xorg-server_1.5.2-2ubuntu3.dsc
dpkg-source -x xorg-server_1.5.2-2ubuntu3.dsc
cd xorg-server-1.5.2/
debuild
cd ..
sudo dpkg -i xserver-xephyr_1.5.2-2ubuntu3_i386.deb
Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac &

Now you can start the Fremantle Beta SDK and run it without crashing all the time :) You can delete the rest of the .deb packages created - they are not needed for Xephyr. If you want to go back (well... "forward" really) to Jaunty's Xephyr package, you can simply use sudo aptitude install xserver-xephyr to upgrade it.
