QShortcut multiple widget instances

[Joel Bodenmann]

I have a custom QWidget that deploys QShortcuts for the Ctrl+F and Escape key sequences. Everything works great as long as I have just one instance of that custom widget. However, as soon as I create multiple instances none of the widgets react on the key sequences anymore.
I would have suspected that the widget that has focus gets the key events and therefore that widgets QShortcuts are "enabled". Apparently I am wrong.

What is the proper solution to handle this problem?

Two things are important when dealing with shortcuts: shortcut parent and context. By default a shortcut has window context so you can't have two of them in different widgets inside that same window. You have to set it explicitly to something narrower, e.g. Qt::WidgetWithChildrenShortcut. With this setting it's important to give the shortcuts appropriate parents to scope them.

auto sh1 = new QShortcut(QKeySequence::Find, someWidget1, SLOT(whatever()), nullptr, Qt::WidgetWithChildrenShortcut);
auto sh2 = new QShortcut(QKeySequence::Find, someWidget2, SLOT(iDontCare()), nullptr, Qt::WidgetWithChildrenShortcut);

this way sh1 will work inside someWidget1 and sh2 inside someWidget2.

Thank you Sir, this helped a lot!
