Double check your code. Something triggers the dock to become visible.
Explicitly hidden child widgets won't become automatically visible
when their parent is shown. This works fine for me:

#include <QtGui>

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QMainWindow window;
    QDockWidget* dockWidget  = new QDockWidget(&window);
    dockWidget->setWindowTitle("Hello Dock");
    window.addDockWidget(Qt::LeftDockWidgetArea, dockWidget);
    window.menuBar()->addAction(dockWidget->toggleViewAction());
    dockWidget->hide(); // <---
    window.show();
    return app.exec();
}
