qApp->processEvents();
QCOMPARE(scrollArea.verticalScrollBar(), vbar);
scrollArea.horizontalScrollBar()->setRange(0, 100);

scrollArea.show();
// Make sure scroll bars are not explicitly hidden by QAbstractScrollArea itself.
QVERIFY(hbar->isVisible());
QVERIFY(vbar->isVisible());
// Hide the OLD scroll bar and ensure that the NEW one is hidden.
hbar->hide();

vbar->hide();
scrollArea.setVerticalScrollBar(new QScrollBar);
qApp->processEvents();

// Hide the NEW scroll bar and ensure that it's visible
// (because the OLD one is visible).
