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

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

Code:

---

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

---

here down the code

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

---

thx

That's right, it's protected and not intended to be called like that. Did you read what QProgressDialog::forceShow() does? Just set minimum duration to 0.

ok I read, but my bar isn't showed, i post whole the code, maybe i have some error in

Code:

---

QProgressDialog progress ( tr ( "Sending configuration..." ) , tr ( "Abort" ) , 0 , commandNumber , this );
progress.setWindowTitle ( tr ( "Sending configuration..." ) );
progress.setWindowModality ( Qt::NonModal );
progress.setMinimumDuration(0);
 
for ( int i=0 ; i < commandNumber ; i++ )
{
	QApplication::processEvents();
 
	// set the progress bar
	progress.setValue ( i );
 
	// check if user choose to abort operation
	if ( progress.wasCanceled () )
	{
		return false;
	}
}
 
progress.setValue ( commandNumber );
