My compiler doesn't seem to like this constructor, it bails out with the
following error:
/home/sebas/kf5/src/kde/workspace/kwin/autotests/integration/globalshortcuts_test.cpp:
In member function ‘void GlobalShortcutsTest::testConsumedShift()’:
/home/sebas/kf5/src/kde/workspace/kwin/autotests/integration/globalshortcuts_test.cpp:79:40:
error: no matching function for call to ‘QAction::QAction()’
QScopedPointer<QAction> action(new QAction); ^~~~~~~
Using this as first argument fixes the build on my machine.
