Our MDI based product is consuming QTitanRibbon v4.17 and faced following issue:
when a ribbon tab is clicked, extra QApplication::focusChanged signal is emitted, as a result the active mdi child is changed.
Could you reproduce it in our example of Ribbon_Application? There is an editor that can be in focus when we click on the tab, then the focus remains on the editor. This is correct, i.e. we cannot reproduce the error. How to do it?
