setBar ( QProgressBar * bar )

[ShaChris23]

hvw59601,

I ran into the same problem as yours. The problem is you have to pass the pointer to QProgressDialog to the constructor of QProgressBar.

Like this:

QProgressDialog dialog;    
QProgressBar* progress = new QProgressBar(&dialog);
progress->setFormat(" ");
progress->setMaximum(0);
progress->setMinimum(0);
dialog.setBar(progress);

QProgressDialog dialog;    
QProgressBar* progress = new QProgressBar(&dialog);
progress->setFormat(" ");
progress->setMaximum(0);
progress->setMinimum(0);
dialog.setBar(progress);

To copy to clipboard, switch view to plain text mode 

I hope that helps.
