示例1: touchStateToString
QDebug operator<<(QDebug dbg, const QTouchEvent::TouchPoint &s)
{
dbg.nospace() << "\"TouchPoint\":"
<< "{ \"id\":" << s.id()
#if (QT_VERSION < QT_VERSION_CHECK(5, 0, 0))
<< ", \"primary\":\"" << (s.isPrimary() ? "true" : "false") << "\""
#endif
<< ", \"state\":" << touchStateToString(s.state())
<< ", \"pos\":\"" << s.pos() << "\""
<< ", \"pressure\":\"" << s.pressure() << "\""
<< " }";
return dbg.space();
}示例2:
PlatformTouchPoint::PlatformTouchPoint(const QTouchEvent::TouchPoint& point, State state)
// The QTouchEvent::TouchPoint API states that ids will be >= 0.
: m_id(point.id())
, m_state(state)
, m_screenPos(point.screenPos().toPoint())
, m_pos(point.pos().toPoint())
{
// Qt reports touch point size as rectangles, but we will pretend it is an oval.
QRect touchRect = point.rect().toAlignedRect();
if (touchRect.isValid()) {
m_radiusX = point.rect().width() / 2;
m_radiusY = point.rect().height() / 2;
} else {
// http://www.w3.org/TR/2011/WD-touch-events-20110505: 1 if no value is known.
m_radiusX = 1;
m_radiusY = 1;
}
m_force = point.pressure();
// FIXME: Support m_rotationAngle if QTouchEvent at some point supports it.
