deepin pr auto review

关键摘要:

• 在ChameleonMovementAnimation类中，setTargetRect方法可能会导致动画开始时直接跳到目标矩形，而不是平滑过渡。
• drawMenuItemBackground方法中，使用QTimer::singleShot来延迟启动动画可能不是最佳选择，因为可能会导致用户体验不佳。
• drawMenuItemBackground方法中，动画的启动和停止逻辑可以进一步简化，避免使用QTimer和isHorizontal变量。
• drawMenuItem方法中，对animation的检查应该在animation->isRuning()之前进行，以避免潜在的空指针异常。
• drawMenuItem方法中，使用painter->setOpacity(1.0 - animation->progress())进行透明度过渡效果可能不正确，因为animation->progress()返回的是一个比例值，而不是一个实际的透明度值。
