Hello Community,

I have the following problem. I am building a GUI with the following hierarchy:

1. Mainwindow -> calls a SubWindow in MDIArea
2. SubWindow shows a QTableWidget with a StartButton
3. StartButton starts an algorithm in a new thread.

I want now to implement a ProgressBar, that is shown in the SubWindow. When I allocate it in the QTableWidget and call this->show() it appears as a new window and blocks my mainwindow when it is set modal. How to work with a QProgressBar correctly, so that I can still use the MainWindow and the ProgressBar is shown only in the SubWindow??

any suggestions ?
