[plasmashell] [Bug 358328] New: Java application systray icon: No context menu

[via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=358328

Bug ID: 358328
Summary: Java application systray icon: No context menu
Product: plasmashell
Version: 5.5.3
Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: System Tray
Assignee: plasma-***@kde.org
Reporter: ***@netcologne.de

I am using The UPnP server "minimserver" and its control app "minimwatch" that
is written in java. When running minimwatch it displays an (old style xembed)
systray icon. The right-mouse context menu is the only way to interact with
it. Unfortunately the menu is not displayed anymore in plasmashell 5.5 making
minimwatch completely useless.

Reproducible: Always

Steps to Reproduce:
1. Install minimwatch. See http://minimserver.com/install-linux-mwatch.html
2. Run it. It will display a systray icon
3. Try to right click the icon to open the context menu

Actual Results:
The context menu does not show up.

Expected Results:
The context menu should be displayed.

With plasmashell 5.3 xembed icons were not supported anymore. I worked around
this by using wmsystemtray. With plasmashell 5.5 this programm does not start
anymore because KDE already has launched a systemtray. So the workaround does
not work anymore. Is there another idea for a workaround?

Another xembed icon (of a program written in perl/gtk) does show its context
menu fine. So it seems to be a problem of a java systray icon.

When right clicking on the icon an entry is written in the ~/.xsession-errors
logfile:

Could not find DBusMenu interface, falling back to calling ContextMenu()
kde.xembedsniproxy: Received click 3 with passed x*y 1691 1169

(I do not know if this is of any interest?)

the first line is plasma trying to see if we have a DBus menu that it can show
itself, before falling back to telling the app (in this case xembedsniproxy) to
show a menuitself.

That's all correct

The second line is xembedsniproxy sending a right click to the java app at that
co-ordinate.

Again, that's all correct.

I think I have some issues with the java apps and focus, but I need to poke
round the java code to find out.

Interestingly the icon is able to open a small popup if the state of the
watched minimserver changes (starting, stopping, rescanning).

So maybe the click event for opening the context menu does not reach the app?
(Well, just a guess, I do not know about the technical internals.)

FWIW, this also happens for radiotray (python/Gtk 3).

oh, that's interesting. Radiotray is one of the ones I tested against.

That could mean it's not a client toolkit issue but something else

just fyi - I can't confirm; radiotray works very well for me and it is
clickable: left (normal menu) and right (context menu) click

Note the toolkit: The Gtk-2 version (Ubuntu Wily) works, but the new Gtk-3
version (from xenial) fails.

Here is a small Java example. The context menu is not displayed:

(To fix the warning, please enable metal instead of Windows LaF in

//UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");

Maybe I am missing something, but after following all of these bugs, I came
full circle back here. I am running DavMail and the icon, when I left click, a
pop up says "JavaEmbeddedFrame", right click does nothing.

I just tested with plasma 5.7.0/5.24 from OpenSUSE Tumbleweed and it is still
here.

In my case, it is a Windows prog running using wine.
BTW, as the icon is constantly animating, plasma keeps spamming my xerror with

kde.xembedsniproxy: Scaling pixmap of window 117440521 "" from w*h 20 20.
