Hi,

I have some os.system commands in my app that take some time executing.

I'd like to display a progress bar over my main windows while the commands are running.
It would also be nice if i could write text to it according to execution state, like "adjusting image", "running recognition", "deleting tmp files"

How can I do this in Qt and python?

Did you even try to do a Google search? One search later I found this:

http://zetcode.com/tutorials/pyqt4/widgets/

Jump down to the part about ProgressBar.

Of course I tried googleing.
The problem is I don't have timed events.
I can't know how long does it take for commands to execute.

I need a progress bar that will load "indefinitely" (from left to right, and back) until the commands are over and I have to close the progress bar manually.

A little more Google and I find the following:

If you set minimum, maximum and value all to zero, then you will get the animation. Then call setProgress().

After this you can just change the text after the different tasks end.

And this is the documentation that describes the behaviour:

Thanks for your help!

Do you have any idea how can I start the progress bar in center of screen, and lock focus on it.
So the user can't click anything while the progress bar is loading

I think the Maemo 5 way of doing things is put the progress bar widget in a dialogue box (see updating in Application Manager, moving files in File Manager, etc.)

Yes, just use the standard QProgressDialog.

took me ages to get something that works for me -

Code:
                progress = QtGui.QProgressDialog("Please Wait", "Cancel", 0, 100, MainWindow)
		progress.setWindowModality(QtCore.Qt.WindowModal)
		progress.setAutoReset(True)
		progress.setAutoClose(True)
		progress.setMinimum(0)
		progress.setMaximum(100)
		progress.resize(800,220)
		progress.setWindowTitle("Loading Something")
		progress.show()
                progress.setValue(0)
                <<do something>>
               progress.setValue(20)
               <<do something>>
              etc.....
              progress.setValue(100)
              progress.hide()

I tried your code, but it doesn't work for me.

I have a specific situation.
There are two windows, application and the camera app
When camera app is closed, the image goes trough processing.
That is where I need the progress dialog, because it takes some time.

The ting is that the process starts right after the camera app is closed. So I get back to the "multitask view" not the actual application. Maybe that is the problem?
