The following members of QML type TouchPoint 已过时。 提供它们是为使旧源代码能继续工作。强烈建议不要在新代码中使用它们。
(obsolete)
This property is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.
A rectangle covering the area of the touch point, centered on the current position of the touch point.
It is deprecated because a touch point is more correctly modeled as an ellipse, whereas this rectangle represents the outer bounds of the ellipse after rotation .
