When calling addSubjob, we need to set the parent widget for the subjobs to the same widget of the baseJob.
- Open Dolphin, copy a dir, A, to the same destination twice
- You should get the file-already-exists dialog, which is supposed to be a modal dialog, but you find that you can still interact with the parent Dolphin window
This happens because:
- Dolphin creates a PasteJob, then calls KJobWidgets::setWindow(job, this)
- The PasteJob creates a CopyJob subjob, but for that subjob KJobWidgets::window() will return a nullptr
Incidentally, I think this is the main reason we got bugs like in the first place... :)
