I want to update widgets while my program is working, so the user can see the progress. For example, I would like to update the text in a column in a QTreeWidget when certain steps are completed, like "Conntecting to host...", "Logging in..." etc. Using QTreeWidget.setText() here and there does not work, I only see the last text when the whole process is completed. A couple of questions on this:

- Are multiple threads required for this?
- Do you have to call QTreeWidget.setText() from the main loop?

Any tips on where to read up on this is appriciated.
