I am having trouble understanding the following code about mVBox.SetExtraData
to "0". How does this check whether tray icon died? shouldn't if (mVBox.isOk())
be if ( ! mVBox.isOk()) ?
This cleans up the tray winid, and will make TrayIcon not singleton.
bool VBoxGlobal::trayIconInstall()
{
int rc = 0;
QString strTrayWinID = mVBox.GetExtraData (VBoxDefs::GUI_TrayIconWinID);
if (false == strTrayWinID.isEmpty())
{
/* Check if current tray icon is alive by writing some bogus value. */
mVBox.SetExtraData (VBoxDefs::GUI_TrayIconWinID, "0");
if (mVBox.isOk())
{
/* Current tray icon died - clean up. */
mVBox.SetExtraData (VBoxDefs::GUI_TrayIconWinID, NULL);
strTrayWinID.clear();
}
}
