QSystemTrayIcon uses D-Bus StatusNotifier on Linux when possible
Implementing org.kde.StatusNotifier DBus interface http://www.freedesktop.org/wiki/Specifications/StatusNotifierItem/ as well as org.canonical.dbusmenu for the limited purpose of showing the tray icon's context menu. If a desktop environment (such as KDE or Unity) has a StatusNotifierWatcher listening, then tray icon information is sent to be displayed by the tray implementation instead of being rendered directly in an XEmbed window. This is necessary because some modern tray implementations no longer provide XEmbed "hosting". [ChangeLog][QPA][Xcb] QSystemTrayIcon uses StatusNotifier D-Bus protocol when the desktop environment supports it Task-number: QTBUG-31762 Done-with: Marco Martin <mart@kde.org> Change-Id: I3b1f744d621eefc7e9c61d1469460ebfcc77fc54 Reviewed-by: Jørgen Lind <jorgen.lind@theqtcompany.com> Reviewed-by: Dmitry Shachnev <mitya57@gmail.com>
