#697 Missing tray icon for 5.1.0-2891 on Linux

[Jon Schewe (BBN)]

When I run davmail directly from the commandline I get the DavMail Gateway window as expected with a davmail icon in my dock.
When I unset XDG_CURRENT_DESKTOP and then run davmail I expect to get a tray icon. Now I get a black square in the tray and a Java icon in my dock.

I'm on Ubuntu 18.04 with OpenJDK 8 and openjfx.

But the DavMail icon in your dock looks better :-)

Anyway, that's one of the reason why I disable tray icon under Gnome by default now.
=> you need a more recent SWT library, version 4.9 is known to work, see:
https://packages.debian.org/sid/libswt-gtk-4-java
or
https://github.com/mguessan/davmail/blob/master/lib/swt-4.9-gtk-linux-x86_64.jar

Note that Debian SID has the right version.

[Jon Schewe (BBN)]

Can you package the swt jar file with the distribution?

[Mickael Guessant]

No, but I can make SwtGatewayTray compatible with older SWT libs, see latest trunk.

[Jon Schewe (BBN)]

I tried downloading the trunk build from https://github.com/mguessan/davmail and it didn't get better. The about dialog shows 5.1.0-trunk.

[Mickael Guessant]

Working fine here, can you please check that you indeed have the old swt.jar ?

=>ps should show:
java -Xmx512M -Dsun.net.inetaddr.ttl=60 -Djdk.gtk.version=2.2 -cp /usr/share/davmail/davmail.jar:/usr/share/java/swt.jar:/usr/share/davmail/lib/* davmail.DavGateway

[Jon Schewe (BBN)]

Here is what I see:

java -Xmx512M -Dsun.net.inetaddr.ttl=60 -Djdk.gtk.version=2.2 -cp /usr/share/davmail/davmail.jar:/usr/share/davmail/lib/*:/usr/share/java/javafx-base.jar:/usr/share/java/javafx-controls.jar:/usr/share/java/javafx-fxml.jar:/usr/share/java/javafx-graphics.jar:/usr/share/java/javafx-media.jar:/usr/share/java/javafx-swing.jar:/usr/share/java/javafx-web.jar davmail.DavGateway

So it seems that I don't have swt installed at all.

[Jon Schewe (BBN)]

I installed libswt-gtk-3-java version 3.8.2 and then started davmail and I see:

java -Xmx512M -Dsun.net.inetaddr.ttl=60 -Djdk.gtk.version=2.2 -cp /usr/share/davmail/davmail.jar:/usr/share/java/swt.jar:/usr/share/davmail/lib/* davmail.DavGateway

[Jon Schewe (BBN)]

Found the problem, /usr/share/java/swt.jar is a symlink. Your shell script is using "-f" and should use "-e".

[Jon Schewe (BBN)]

Running with XDG_CURRENT_DESKTOP set to ubuntu:GNOME prevents any tray icon.

Fixing "-e" vs. "-f" and unsetting XDG_CURRENT_DESKTOP I get

I installed libswt-cairo-gtk-3-jni and ran with XDG_CURRENT_DESKTOP cleared and I get my tray notification.
