示例1: sliderMoved
void tst_QDial::sliderMoved()
{
//this tests that when dragging the arrow that the sliderMoved signal is emitted
//even if tracking is set to false
QDial dial;
dial.setTracking(false);
dial.setMinimum(0);
dial.setMaximum(100);
dial.show();
QPoint init(dial.width()/4, dial.height()/2);
QMouseEvent pressevent(QEvent::MouseButtonPress, init,
Qt::LeftButton, Qt::LeftButton, 0);
qApp->sendEvent(&dial, &pressevent);
QSignalSpy sliderspy(&dial, SIGNAL(sliderMoved(int)));
QSignalSpy valuespy(&dial, SIGNAL(valueChanged(int)));
{ //move on top of the slider
init = QPoint(dial.width()/2, dial.height()/4);
QMouseEvent moveevent(QEvent::MouseMove, init,
Qt::LeftButton, Qt::LeftButton, 0);
qApp->sendEvent(&dial, &moveevent);
QCOMPARE( sliderspy.count(), 1);
