- Create a new Qt Widgets Application project using defaults.
- Build and run the project.
- While the application is running, try closing its "Application Output" tab.
A message box will inform you that the application is still running.
- Click "Force Quit".
The application is being killed, but the tab remains open.
- Try closing the "Application Output" tab again.
Now it is being closed.
After you clicked "Force Quit" and the application was killed, the tab should be closed.
