applicationDirPath() issue with the windows "program files" directory

[john_god]

Hi guys

I'm trying to launch a html file from my app:

QString path = QApplication::applicationDirPath();
    QString str = path +tr("/mat_html/mat_manual_en.html");
 
    if ( ! QDesktopServices::openUrl(QUrl( str, QUrl::TolerantMode ))  )
        QMessageBox::about(0,tr("Error"),tr("Error. Help file not found")+"\n"+str);

QString path = QApplication::applicationDirPath();
    QString str = path +tr("/mat_html/mat_manual_en.html");

    if ( ! QDesktopServices::openUrl(QUrl( str, QUrl::TolerantMode ))  )
        QMessageBox::about(0,tr("Error"),tr("Error. Help file not found")+"\n"+str);

To copy to clipboard, switch view to plain text mode 

So far so good, it work's on several directorys, except for the "program files" windows directory.

It seems the portuguese windows version creates some kind of simbolic link directory where in my explorer the file.exe directory is "c:/programas/math graphica", but in command line and the str output is "c:/program files/math graphica".

so I tried a hardcoded version wich still doens't work:

QString str = path +tr("/mat_html/mat_manual_en.html");
    QString str2 = "C:/Program Files/Math Graphica"+tr("/mat_html/mat_manual_en.html");
    str2 = "C:/Programas/Math Graphica"+tr("/mat_html/mat_manual_en.html");
 
if ( ! QDesktopServices::openUrl(QUrl( str )) &&
          ! QDesktopServices::openUrl(QUrl( str2 , QUrl::TolerantMode))   )
        QMessageBox::about(0,tr("Error"),tr("Error. Help file not found")+"\n"+str);

QString str = path +tr("/mat_html/mat_manual_en.html");
    QString str2 = "C:/Program Files/Math Graphica"+tr("/mat_html/mat_manual_en.html");
    str2 = "C:/Programas/Math Graphica"+tr("/mat_html/mat_manual_en.html");

if ( ! QDesktopServices::openUrl(QUrl( str )) &&
          ! QDesktopServices::openUrl(QUrl( str2 , QUrl::TolerantMode))   )
        QMessageBox::about(0,tr("Error"),tr("Error. Help file not found")+"\n"+str);

To copy to clipboard, switch view to plain text mode 

So I'm running out of ideias

Convert the file path to a valid file: URL as in the QDesktopServices docs example:

QString path = QString("file:///%1/%2")
  .arg(QApplication::applicationDirPath())
  .arg("mat_html/mat_manual_en.html");
QDesktopServices::openUrl(QUrl(path, QUrl::TolerantMode));

QString path = QString("file:///%1/%2")
  .arg(QApplication::applicationDirPath())
  .arg("mat_html/mat_manual_en.html");
QDesktopServices::openUrl(QUrl(path, QUrl::TolerantMode));

To copy to clipboard, switch view to plain text mode
