KStandardAction doesn't seem to have the necessary c++ slot to python slot changes needed, this app doesn't work http://kubuntu.org/~jriddell/tmp/kapplication.py KStandardAction.close(self, self.hideMainWindow, self.actionCollection()) Try KStandardAction.close(self.hideMainWindow, self.actionCollection()) PyKDE and PyQt slot specifications only specify the slot method or function, not the slot's owner (first 'self') and method (self.hideMainWindow). Otherwise, if you were using the Qt syntax, the slot name would be a char *, not a method address. The close() method is included in KStandardAction inPyKDE (see sip/.kdeui/kstandardaction.sip).

Due to the fact that the Oxygen theme is the standard KDE4 theme, the fact
that PyKDE4 doesn't show the menus will be a really big drawback for it and
might lead to the point, that only few applications will be written (or a lot
of complaints will arise). IMHO, this problem should be fixed asap.
For now, I'm doing this in my application:
if QtGui.QApplication.style().objectName() == 'oxygen':
QtGui.QApplication.setStyle('Cleanlooks')
Not that is a proper fix, but better than no menus at all in my opinion.

IMHO, this problem should be fixed asap. BTW, pure PyQt4 shows the menus correctly when used with the Oxygen style. Importing some PyKDE4 modules triggeres the faulty behavior.

(That's also without Oxygen, which is a different problem). KApplication uses QtDBus, so there's no eliminating that. That should ensure the application gets automatically registered though. You can change the organization domain via KAboutData - didn't try that though. I guess what I'd try is some simpler stuff - see if you can communicate via DBus at all, query for available services - in general, see if anything works. If it doesn't, maybe it'll turn up something that provides more insight. Send me whatever you come up with (working or not) and I'll see where I can go from there. I really have no understanding of the whole subject and it looks like a few weeks of learning curve for me to dig into it much more. Doesn't look like a quick fix is available from this end, but I'm certainly willing to go at it.

Without knowing more about the way events are handled in the QtDBus and python-dbus implementations, it's difficult to give you advice. There may be a way to make them play well together, but perhaps this will involve digging around in the low-level Python dbus API or even in the internal _dbus_bindings module. I imagine you've already looked into this. Did you make any progress? David ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Right, with QApplication QtDbus doesn't get loaded and everything works, with KApplication QtDbus does get loaded and it freezes if using python-dbus with the Qt mainloop (setting set_as_default=False makes it use the glib mainloop, no freeze but you won't get any dbus signals either). Trolltech tell me they can't recreate it in Qt 4.4 RC 1 so maybe this has been magically fixed, we should find out tomorrow.
