busy progress bar without thread ?

QMake version 2.01a
Using Qt version 4.2.1 in /usr/lib/qt4/lib

The current stable version of Qt is 4.4.3. Probably it's time to upgrade. Anyway, have you tried the trick setting the value to something != 0? And again, which style you are using?

Default Style
this is the test

int main(int argc, char *argv[]){
    QApplication app(argc, argv);
    QMainWindow window;
    QProgressBar* progressBar = new QProgressBar(&window);
    progressBar->setMaximumHeight(16);
    progressBar->setMaximumWidth(200);
    progressBar->setTextVisible(false);
    progressBar->setMaximum(0);
    progressBar->setMinimum(0);
    progressBar->setValue(1); // ??? don't move the bar
    window.statusBar()->addPermanentWidget(progressBar);
    window.statusBar()->showMessage("Loading");
    window.show();
    app.exec();
}

int main(int argc, char *argv[]){
    QApplication app(argc, argv);
    QMainWindow window;
    QProgressBar* progressBar = new QProgressBar(&window);
    progressBar->setMaximumHeight(16);
    progressBar->setMaximumWidth(200);
    progressBar->setTextVisible(false);
    progressBar->setMaximum(0);
    progressBar->setMinimum(0);
    progressBar->setValue(1); // ??? don't move the bar
    window.statusBar()->addPermanentWidget(progressBar);
    window.statusBar()->showMessage("Loading");
    window.show();
    app.exec();
}

First of all, could you finally start using appropriate [code] tags, please? I already sent instructions to you.

Secondly, the "default style" depends on the environment. The following piece of code prints out which style is the default style for you:

qDebug() << app.style()->objectName();

qDebug() << app.style()->objectName();

To copy to clipboard, switch view to plain text mode 

You can try different styles by passing it as a command line argument:

./myapp -style windows

./myapp -style windows

To copy to clipboard, switch view to plain text mode 

You can try different styles like "windows", "plastique", "cleanlooks" etc. Does any of them work?

So you're probably hit by this bug: QProgressBar "busy indicator" mode doesn't work in Cleanlooks style. It was fixed in Qt 4.3.0. So updating to a recent version of Qt would help as suggested earlier.
