@Christian and @Aaron: thanks for your replies :) This morning I've modified a little the sourcecode in order to call "qdbus org.kde.kmix /kmix/KMixWindow org.qtproject.Qt.QWidget.show", disabled the "old" KMix tray icon, and it works. It's kinda clumsy, but it works :) Regular KMix widget gets displayed when the corresponding button is clicked, and it won't appear at login anymore. These are already great news for me :) Now, I think we have some options here: * ship this applet _as is_ in KDE4, it is functioning afterall; * port and/extend/improve this applet to get the most out of KDE5/Plasma/QML2; I'm ok with both of these, now you guys tell me what do you think. - Diego ----------------------------------------------------------- This is an automatically generated e-mail.
