[Qt-interest] qprocess related with qprogressbar

[mierdatutis mi]

Many thanks again.
I put in my shell script, some outpouts to stdout that the function
that read all the output of the script can compare the string and can
increment the progress bar.
The problem that I have is that the progressbardialog dissapear every
time that the program enter in the output capture. Could I do that the
progressbar is always on top?

Many thanks

This is the code:

void MainWindowImpl::salida()
{
	QStringList strs;
	
    QByteArray result=proc2->readAllStandardOutput();
    qDebug() << proc2->readAllStandardOutput();

    QStringList lines = QString(result).split("\n");
    foreach (QString line, lines) {
        texto->append(line);
        qDebug() << line;

    QProgressDialog progress("DESCARANDO SINOPSIS...", "&Wake Up!", 0, 7, 0);
	progress.setWindowModality(Qt::WindowModal);
   	progress.show();	


	progress.setRange(0,100);
	progress.setValue(0);
	QString strss = "hola";
			qDebug() << "El valor es.." << line;
			qDebug() << "el valor de comparaicon es .." << strss;
	QString strxx;
		
		
	

	
		if ( line.compare("hola",Qt::CaseInsensitive)) {
			qDebug() << " NO HEMOS ENTRADO";
		}
		else {
			qDebug() << "ENTRADO";
			
						
			progress.setValue(10);
			progress.setFocus();
		}
			
		
		if ( line.compare("hola2",Qt::CaseInsensitive)) {
			qDebug() << " NO HEMOS ENTRADO";
		}
		else {
			qDebug() << "ENTRADO";
			progress.setValue(30);
		}	
			
		if ( line.compare("hola3",Qt::CaseInsensitive)) {
			qDebug() << " NO HEMOS ENTRADO";
		}
		else {
			qDebug() << "ENTRADO";
			progress.setValue(40);
		}
			
		
		if ( line.compare("hola4",Qt::CaseInsensitive)) {
			qDebug() << " NO HEMOS ENTRADO";
		}
		else {
			qDebug() << "ENTRADO";
			progress.setValue(50);
		}	
		
		if ( line.compare("hola5",Qt::CaseInsensitive)) {
			qDebug() << " NO HEMOS ENTRADO";
		}
		else {
			qDebug() << "ENTRADO";
			progress.setValue(60);
		}
			
		
		if ( line.compare("hola6",Qt::CaseInsensitive)) {
			qDebug() << " NO HEMOS ENTRADO";
		}
		else {
			qDebug() << "ENTRADO";
			progress.setValue(100);
		}	
		
	
		
    }
   }
