systray icons do not show up in indiactor bar

[koppi]

When running a qt4 based software, the systray icon does not show up any more in unity and on the console, it prints the following error messages:

Could not save icon as '/tmp/sni-qt_server_22456-MTXUll/icons/hicolor/16x16/apps/server_22456_1fd07571a5278bdba6564f8b47480a18.png'

Just something that happened to me recently, maybe it helps:

I had an app that had just a 26x26 icon for the tray, and sni-qt would not display it, with that error. Manually scaled the icon to 48x48 and voilá, it started working.

Based on the log, I would suggest checking for file permission issues: is the "/tmp/sni-qt_server_22456-MTXUll" dir correctly created? Does it happen with all Qt4 applications which have a systray?

It only happens with one of my test qt4 apps, where the systray icon
worked fine before the invention of the unity system.

Is it possible for you to post a code example? This way I can either fix it in sni-qt or in the worse case, suggests way to get your code to work with it.

Aurélien, while writing the code sample in question, it turned out,
that I forgot to include the icon.png file in my qrc resources file.
After adding the icon file to the qt4 resources file, the icon showed
up and everything worked as expected.

Kind regards and thanks for your patience.

OK, closing as invalid then.
