My update to 16.04, from 15.10, broke RadioTray. I uploaded and am trying KRadio4. Am noticing that when I close all windows and depend on the Kradio4 Panel Icon, clicking on "Open Kradio4" doesn't work. This means that if I want to change a station (I listen to Internet Radio), I have to killall, then restart KRadio4. I haven't found any other way, yet, to "re-invoke" the KRadio4 dialog window. Reproducible: Always Steps to Reproduce: 1. Start KRadio4 2. Pick a station. Close all Windows. 3. Try to "open" KRadio4 from the tray Icon. Actual Results: Nothing happens. Expected Results: Opens the KRadio4 dialog window.
Update: After rebooting, the KRadio4 Icon showed up in the icon tray. However, the <Open KRadio4> button on the separate Play/Pause Icon(?) still doesn't actually open KRadio4. This would appear to be a minor bug (if a bug at all?).
I assume you mean Media Player applet with the "Open KRadio4" button?
Yes. In the meantime, I've noticed that the "Open..." button also doesn't work for other apps. As an aesthetic matter, the Media Player applet displays three "blank/generic" music icons on the left (one larger with two superimposed at the bottom) when streaming radio on KRadio. Strikes me as rather pointless, ugly and inelegant (also makes less room for song information). Wouldn't it be more elegant to simply omit icons if none are available?
All that the media player applet does is ask the application to raise itself. It it doesn't, that's a bug in the application. It does work with Nuvola player, for instance. The application can also announce that it doesn't support raising itself (for example VLC player) at which point the media player will not offer this option. Try calling the method directly to see whether the bug is on our side or the player's: qdbus org.mpris.MediaPlayer2.PLAYERNAME /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Raise The "CanRaise" property tells you whether the application claims to be able to honor such requests.
