Answer 1

On Qt 5.9.1 you can also use a hack without any platform-specific code at all. See https://stackoverflow.com/a/46488514/8695355

In Qt-Carbon, see Qt4 Mac Dock Icon Click. It explains how to install a reopen event handler.

In Qt-Cocoa, you should get the application delegate with [[NSApplication sharedApplicaion] delegate] and add you own applicationShouldHandleReopen:hasVisibleWindows: method with class_addMethod. I have not actually tried this.

I've done this for an open-source project. See the code here: https://github.com/KDAB/Charm/blob/master/Charm/MacApplicationCore.mm
