[Qt-interest] QProcessBar while read file

[Ulf-Alexander v. Ceumern-Lindenstjerna]

Hi,

QProgressDialog is your friend:

http://doc.trolltech.com/4.5/qprogressdialog.html

see examples:

     QProgressDialog progress("Copying files...", "Abort Copy", 0,
numFiles, this);
     progress.setWindowModality(Qt::WindowModal);

     for (int i = 0; i < numFiles; i++) {
         progress.setValue(i);

         if (progress.wasCanceled())
             break;
         //... copy one file
     }
     progress.setValue(numFiles);


Cheers, Ulf
