Or it could be done as another way of implementing QLabel (another name, some more functions), but I do not know if it is possible to modify the constructor in PyQt. greetings Torsten -- Torsten Marek <[EMAIL PROTECTED]> ID: A244C858 -- FP: 1902 0002 5DFC 856B F146 894C 7CC5 451E A244 C858 www.keyserver.net -- wwwkeys.eu.pgp.net signature.asc Description: PGP signature signature.asc Description: OpenPGP digital signature

Fine by me.
I guess what's really needed is a cross-platform QSysTray class.
Of course you are right - but I gave away my harddisk with my win2k
installation, thus, I cannot be of any help regarding
cross-platformness. And is there such a concept on OS X?
Regarding windows, as far as I remember, it is impossible to embed
widgets into the TNA in Windows, just icons by
ShellNotifyIcon{A,W}(...), that makes event handling a bit more
difficult. But I might be proven wrong.

[PyKDE] Systray icons in PyQt
Hello all,
for a project of mine, I need a systray icon. I know that it is possible
to get a one with PyKDE and there is a solution for PyGtk, but not for
PyQt itself. But the code is rather easy and I found out that the ppl of
qjackcontrol implemented a systray icon in Qt for themselves, using the
spec + sample code from freedesktop.org (sorry, but I'm too lazy right
know to find out all the links). All you need to do is to call some
functions in libX11.so. For that, you need the Display
(qt_x11_display()) and the WindowID (QWidget.winId())
So far, there are several ways to do the C calls from Python:
- extension module
- Pyrex
- ctypes
I chose the ctypes way and after some hassle (mostly typos!), I got it
to actually work. It's not very advanced by now. To try it out, just
replace the icon filename with something icon on your system. I put in
all values in good faith and they are poorly documented right now, but
I'll fix that later on.
I'll go to bed now
greetings
Torsten
