Fix OTBApplicationOutputImageChanged and ExecutionDone slots not being called

Victor Poughon requested to merge bug-qt-execute into develop

Summary

Fix a bug where output images are not loaded after app execution in monteverdi.

It was introduced by the combination of !161 (merged) and !441 (merged), it was caused by two problems:

  • Overriding a non virtual slot in mvdQtWidgetView.h
  • Broken signal/slot connection using the old Qt syntax in mvdMainWindow.cxx

Fixed by making the overriden function virtual, and using the new Qt 5 syntax for signal/slot connection.

Rationale

Fix the bug.
