The program that opens the ProgressDialog owns it via its main window. If your application is not in focus while opening the dialog, this might confuse the Qt mechanics. But I wouldn't think that this is hard to solve. Applications continue to run and update their windows when in "Task view".

the only thing I cant get working is the "infinite lopping"
I set everything to 0
and call setProgress, but it gives the error that QProgressDialog has no attribute

Did you read the documentation?
http://doc.qt.nokia.com/4.6/qprogressdialog.html
It looks very much like the it will not behave like a normal ProgressBar. But you'll have to read.

I can't figure it out
Here is my code
Btw. the code is run in a controller class, so I pass the parent as self.mainWindow, which is a reference to mainWindow class
Here is my code
Code:
progress = QtGui.QProgressDialog("Please Wait", "Cancel", 0, 100, self.mainForm)
progress.setWindowModality(QtCore.Qt.WindowModal)
progress.setAutoReset(True)
progress.setAutoClose(True)
progress.setMinimum(0)
progress.setMaximum(100)
progress.resize(800,220)
progress.setWindowTitle("Running OCR engine")
progress.show()
progress.setValue(0)
os.system('convert '+ lastPic+ ' test.tif')
progress.setValue(30)
os.system('tesseract test.tif test')
progress.setValue(100)
progress.hide()

Guys - QProgressDialog is asynchronous, you need to either update via signals, asynchronously, or manually force the redraw. Also, with 4.6, if you just want to say I'm busy, and not a real progress bar, there is a window attribute for the little circular busy indicator.
