The problem with my code below is that on US/UK keyboard layouts + is generated with shift + =, but when the user uses both the control and shift modif
+
shift + =
Instead of Key.onPressed use Shortcut and its sequence property :
Key.onPressed
Shortcut { sequence: StandardKey.ZoomIn onActivated: zoom(true) }
Your issue is mentionned in this section of the QKeySequence documentation.
