A new entry to the wiki would be a good idea. As soon as I can get clean examples of each plus all the parts needed. The home / statusbar / taskbar is a set and I'd prefer to get all three going with full examples in a deb if possible. I have the first two.

May I impose on your code wizardry once more - how about a taskbar item. I'd like to replace Contacts with a shell program launcher or something similar.
Changing Statusbar to Taskbar (and adding an appropriate desktop file under the hildon-navigator directory, Type=python) makes it recognized in Panels, but no icon, and the taskbar shifts up. I didn't put a menu in (yet) so that might be the problem.
Here's tasknavigator plugin, wich opens proper menu. (again from C example)
Code:
import gtk
import hildondesktop
class statusbar_applet(hildondesktop.TaskNavigatorItem):
def __init__(self):
hildondesktop.TaskNavigatorItem.__init__(self)
self.button = gtk.Button()
self.button.set_image(gtk.image_new_from_stock(gtk.STOCK_YES, gtk.ICON_SIZE_MENU))
self.button.set_name("hildon-navigator-button-one")
self.button.set_size_request(80,80)
self.button.connect("clicked",self.popup_menu)
self.create_menu()
self.add(self.button)
self.show_all()
def create_menu(self):
self.menu = gtk.Menu()
menu_item = gtk.MenuItem("Hello World!")
menu_item.connect('activate',self.show_dialog)
self.menu.append(menu_item)
self.menu.set_name("menu_from_navigator")
self.menu.show_all()
def popup_menu(self,widget,data=None):
self.menu.popup(None,None,self.menu_position,0,gtk.get_current_event_time())
def show_dialog(self,widget,data=None):
mdlg = gtk.MessageDialog(None,0,gtk.MESSAGE_INFO,gtk.BUTTONS_OK,"Hello World!")
mdlg.run()
mdlg.destroy()
def menu_position(self,data=None):
x = self.button.allocation.x + self.button.allocation.width
y = self.button.allocation.y
return (x,y,True)
def hd_plugin_get_objects():
plugin = statusbar_applet()
return [plugin]

Thanks again!.
Saved the above to /usr/lib/hildon-desktop/pytaskbar.py and created /usr/share/applications/hildon-navigator/pytaskbar.desktop with:
I'll see if I can package this and/or write something up (including the home hello world).
I'm really beginning to like Python as my middle level language (between C and simple shell scripts).

Unfortunately, like tz1 said, there are NO error messages when something fails...
When starting desktop environmet with af-sb-init.sh start, debug prints are printed to console, including python errors.

http://www.zdez.org/pydesktop.tgz and http://www.zdez.org/PythonHildonDesktopExample-0.1.deb are available.
I don't have a readme, but this includes the home (which doesn't pop-up anything, but pyculator and other demos are fuller examples and available), statusbar, and taskbar applet and desktop files (close to the posts here, but with a few of my mods).
It would be nice to move them somewhere in the maemo garage.
Also, feel free to improve on them. The Debian installs the files, the tgz is the source/install tree (since you can text-edit the python code I didn't bother with a source-move-to-destination, but did include a packager script that creates the .deb file).
I don't have a postinst file, and that may be necessary to activate them automatically instead of using the control panel.
Speaking of which, python control panel applets...?

I've tried in scratchbox, but much of what I want to do is dependent on the hardware (e.g. GPS) that isn't emulated. I haven't but should try the QEMUed N8x0 but that is fairly new. The Ubuntu hildon stuff isn't exactly the same as Nokia/Maemo. I also get confused building under the X86 then switching to ARMEL, and switching back.
A lot of hiccups are in the desktop or other resource files and it is hard to keep my tablet and scratchbox environment (x2 - armel/x86) enough in sync to make it work smoothly but not so much as something breaks. I have enough trouble when I forget to fix the DNS entry in scratchbox (it copies resolv.conf from the main at install, but if I can't see the DNS servers because I've moved things break).
The (earlier?) hello-world-desktop in C was all three applets mixed together plus control panel, and I couldn't even get them successfully separated.
But for all that, Scratchbox/Maemo is actually a nice environment, but it has a few annoyances and I haven't mastered it. I really should spend some time going through it instead of rushing to get programs out.

WOW! Great job to everyone working on this. I'm trying to adapt the task navigator menu to the statusbar item. Here's the code I have:
And here's a screenshot of how the menu comes up:
As you can see, the menu shows up in the wrong spot by... a lot... any ideas?

You need to do the python equivalent of gtk_window_move(menu,x,y) and probably eventually gtk_widget_set_size_request(menu,w,h) on the menu object.
The osso-statusbar-cpu applet and advanced backlight applet have the C code for doing very similar things like menus and updates.

OK, I got the menu working! I looked at the code for osso-statusbar-cpu, and tried to translate it to python. Eventually, I got it working. Here's the code I came up with for the menu_position function on a statusbar:
It works great! It even handles if the menu is too big to fit on the screen!
[edit]And here's the full source code for a button in the statusbar. It's actually a ToggleButton, so it'll be active when the menu is popped up, and inactive when it's not!
