Shift+F1 only works if a QWhatsThis action has been added to the menu/toolbar

You were right, it doesn't work. I made it work this way:

#include <QApplication>
#include <QWidget>
#include <QAction>
#include <QKeySequence>
 
int main(int argc, char **argv){
  QApplication app(argc, argv);
  QWidget w;
  QAction act("quit", &w);
  act.connect(&act, SIGNAL(triggered()), &w, SLOT(close()));
  act.setShortcut(QKeySequence(Qt::Key_Escape));
  w.addAction(&act); // this here does the trick
  w.show();
  return app.exec();
}

#include <QApplication>
#include <QWidget>
#include <QAction>
#include <QKeySequence>

int main(int argc, char **argv){
  QApplication app(argc, argv);
  QWidget w;
  QAction act("quit", &w);
  act.connect(&act, SIGNAL(triggered()), &w, SLOT(close()));
  act.setShortcut(QKeySequence(Qt::Key_Escape));
  w.addAction(&act); // this here does the trick
  w.show();
  return app.exec();
}
