[Qt-interest] Qt Assistant in god-mode? (Simple Text Viewer Example)

[slayer81 at gmx.de]

Hello Qt people :)

I adapted the SimpleTextViewer example, where a help file collection is started by spawning a QProcess running Qt Assistant.
Link: http://doc.qt.nokia.com/4.7-snapshot/help-simpletextviewer.html

When passing a non-existent help file as argument to Qt Assistant, it shows a error message, but QProcess does _not_ exit.

I wonder why that's the case, because the following lines in application.cpp (see commented code snippet) seem to check that error, dont they?

<<<<<<<<<<<<<<<< application.cpp (bool startAssistant)<<<<<<<<<<<<<<<<
         QStringList args;
         args << QLatin1String("-collectionFile")
             << QLibraryInfo::location(QLibraryInfo::ExamplesPath)
             + QLatin1String("/help/simpletextviewer/documentation/simpletextviewer.qhc")
             << QLatin1String("-enableRemoteControl");

         /* call with wrong collection file argument ... */
         proc->start(app, args);

         /* ... and proc will be in state QProcess::Running ... */
         if (!proc->waitForStarted()) {
             /* ... therefore you'll not see this message box (in this case) */
             QMessageBox::critical(0, QObject::tr("Simple Text Viewer"),
                 QObject::tr("Unable to launch Qt Assistant (%1)").arg(app));
             return false;
         }
<<<<<<<<<<<<<<<<

Doesnt change when calling with option "quiet".
I currently use Qt 4.6.3 on Windows 7.

Cheers,
Paule
