Description Adrian Likins 2003-02-13 19:46:48 UTC
Description of problem:
I added the RHN applet, then I added the "korn" applet. 
When I right clicked on the "korn" applet, and selected
to remove it, it went away, but took the RHN applet
with it. 

Version-Release number of selected component (if applicable):

How reproducible:
Tried it two or three times, reproduced each time

Steps to Reproduce:
see above

Comment 1 Ngo Than 2003-02-13 21:22:14 UTC
it should be a bug in rhn-applet. pam-panel-icon works fine

Comment 2 Daniel Veillard 2003-02-19 15:49:26 UTC
Hum, I installed KDE from the last beta, I could not find
the "korn" applet in the list suggested, so I tried with various
ones, like the color picker, the clock, etc ... I installed and
uninstalled them without having a problem with the applet.
I can't reproduce this, please give me a reproductible way to
trigger the bug if any


Comment 3 Daniel Veillard 2003-02-20 00:29:57 UTC
Okay I think I managed to reproduce the problem with KMix,
I will try to fix it.


Comment 4 Daniel Veillard 2003-02-20 18:21:31 UTC
Well the call to gtk.mainloop() from python exits, apparently normally.
It can be traced back to a destroy being called on the Window identifier
associated to the rhn-applet icon

        self.applet_window = eggtrayicon.create_window("rhn-applet")
        self.applet_window.connect("destroy", self.exit_applet1)

then the callback exits the application cleanly, but the problem is
that the KDE environment framework destroys the window associated to
the applet.


Comment 5 Daniel Veillard 2003-02-21 12:58:21 UTC
Hum, it's getting too deeply associated to X Windows event processing for
me to make real progresses, basically what's happening is the following:

  When the KMix is stopped, the eggtrayicon.c windows for the icon get
a succession of event, the 2 last ones are an UnmapNotify and a ReparentNotify.

  If I ask the event filter to remove the ReparentNotify from the processing
chain, I get some funky behaviour (i.e. the applet is actually remapped
into another top-level window and presented as such and later brought back
into the icon tray, plus a bunch of warnings).
  So it seems basically that the ReparentNotify event processing for the
eggtray icon is misinterpreted and generate the same callback as a Destroy
would. It's pretty mysterious to me at this point.
  I also see that the applet get events with type 110 which don't even seems
to be listed in X11/X.h 

  Havoc, can you help there ?

Comment 9 Owen Taylor 2003-04-02 13:30:05 UTC
Sounds like the KDE tray is not properly implementing the XEMBED protocol -

 The protocol ends in one of three ways:

  1.The embedder can unmap the client and reparent the client window to the root
  window. If the client receives an ReparentNotify event, it should check the 
  parent field of the XReparentEvent structure. If this is the root window of 
  the window's screen, then the protocol is finished and there is no further 
  interaction. If it is a window other than the root window, then the protocol 
  continues with the new parent acting as the embedder window.


(Actually, this text was added *after* the KDE implementation was written,
but the KDE folks didn't object and expressed an interest in updating to
the new spec.)

Someone would have to take a look why these reparent events are being generated
and whether it can be fixed.

Comment 11 Bill Nottingham 2003-10-21 20:43:37 UTC
This is fixed now, correct?

Comment 12 Daniel Veillard 2003-10-21 21:04:15 UTC
Hum, the applet got his system tray code updated, but if the problem
was on the tray side itself, I can't tell.


Comment 13 Andrea Santilli 2004-03-23 00:18:39 UTC
This problem occurs on my system too with rhn-applet-gui and with
eggcups as well.
It seems more raisonable to rewrite them from scratch using QT and

Comment 14 Andrea Santilli 2005-12-21 23:50:01 UTC
well this bug seems to be fixed in FC4, doesnt it?

This was fixed a long time ago, I believe.
