QProgressDialog and forceShow(), how to use this protected member?

[mattia]

Hello, i got a problem with QProgressDialog, i'd like to show quickly the QProgressDialog but i get this error:

/usr/local/Trolltech/Qt-4.3.2-commercial-static/include/QtGui/qprogressdialog.h:101: error: ‘void QProgressDialog::forceShow()’ is protected

/usr/local/Trolltech/Qt-4.3.2-commercial-static/include/QtGui/qprogressdialog.h:101: error: ‘void QProgressDialog::forceShow()’ is protected

To copy to clipboard, switch view to plain text mode 

here down the code

QProgressDialog progress ( tr ( "Sending configuration..." ) , tr ( "Abort" ) , 0 , commandNumber , this );
	progress.setWindowTitle ( tr ( "Sending configuration..." ) );
	progress.setWindowModality ( Qt::NonModal );
	progress.setMinimumDuration(0);
	progress.forceShow(); // <-- error forceShow() is protected

QProgressDialog progress ( tr ( "Sending configuration..." ) , tr ( "Abort" ) , 0 , commandNumber , this );
	progress.setWindowTitle ( tr ( "Sending configuration..." ) );
	progress.setWindowModality ( Qt::NonModal );
	progress.setMinimumDuration(0);
	progress.forceShow(); // <-- error forceShow() is protected
