对Qt Test
Qt 6 的改动是有意识地使框架更高效、更易用的结果。
我们努力在每个版本中保持所有公共 API 的二进制和源代码兼容性。但为了使 Qt 成为一个更好的框架，有些改动是不可避免的。
在本专题中，我们总结了Qt Test 中的这些变化，并提供了处理这些变化的指导。

QTouchEventSequence 类
QTest::QTouchEventSequence 获取 参数的函数已移至一个新类：QTest::QTouchEventWidgetSequence。受影响的函数列表如下：QWidget
- QTest::QTouchEventSequence::press(int touchId, constQPoint &pt,QWidget *widget)
- QTest::QTouchEventSequence::move(int touchId, constQPoint &pt,QWidget *widget)
- QTest::QTouchEventSequence::release(int touchId, constQPoint &pt,QWidget *widget)
同样，接收QWidget 参数的QTest::touchEvent() 重载已改为返回 QTouchEventWidgetSequence 对象。
