Launching Qt Assistant from code on Mac

[dmateer]

The recommended way of launching Qt Assistant as a custom help viewer is to start a process. The example on that page works great for Linux, but how does one achieve this on Mac, where the Qt Assistant is in an app bundle? Right now I am doing this:

QStringList args;
    args << QLatin1String("-collectionFile")
            << helpPath_
            << QLatin1String("-enableRemoteControl");
 
#ifdef Q_WS_MAC
    QString app = QLibraryInfo::location(QLibraryInfo::BinariesPath) + QLatin1String("/Assistant.app/Contents/MacOS/Assistant");
#else
    QString app = QLatin1String("assistant");
#endif
 
    process_->start(app, args);
    process_->waitForStarted();

QStringList args;
    args << QLatin1String("-collectionFile")
            << helpPath_
            << QLatin1String("-enableRemoteControl");

#ifdef Q_WS_MAC
    QString app = QLibraryInfo::location(QLibraryInfo::BinariesPath) + QLatin1String("/Assistant.app/Contents/MacOS/Assistant");
#else
    QString app = QLatin1String("assistant");
#endif

    process_->start(app, args);
    process_->waitForStarted();

This is working, but seems very hackish and fragile to me. Is there a cross-platform way of doing this? If not, is that the recommended way of launching an application within an app bundle as a process? Is the internal folder structure of a Mac app bundle stable?

Thanks for any pointers.

"open Assistant.app" ? however i don't know how to pass arguments to Assistant in that case (man open)

Well, I gave that a try, but the QProcess doesn't seem to "hang on," so the remote control commands get orphaned. I tried using the -W parameters as well, but it didn't make a difference.
