@mrprobert,

Okay, It seems that when the QWebEngineView (the big image in the left side) finishes being updated it steals focus to itself and does not return it. This is a bug in Qt. I have had to extensively re-engineer the SelectFiles.h/cpp/ui files using my own focusWidget tracking and QTimers to prevent interrupting the previous load of the QWebEngineView with a new one.

All of this now seems to work. I can use Arrow keys to now happily walk down the list of cover images.

FWIW - Instead of using WebEngineView to show the detailed image of the cover you can instead use the splitter to hide the WebEngineView and use the + and - keys to set the size of inline thumbnail images to the immediate right of the file name.

Your change request is actually a "bug report" as far as I am concerned and its fix will appear in the next release of Sigil.


Thank you.
