deepin pr auto review

我对这段代码的审查意见如下:

  1. 语法逻辑:
  • 修改后的代码添加了对动画状态的检查 st == QAbstractAnimation::Running,这是一个合理的改进,确保只有在动画运行时才执行相关逻辑。
  • 但是,变量 st 在提供的代码片段中没有定义,这可能会导致编译错误。建议在使用前确保 st 已正确定义和初始化。
  1. 代码质量:
  • 代码注释解释了 underMouseState_MouseOver 之间可能存在的差异,这有助于理解代码的意图。
  • 建议将 st 变量的命名改为更具描述性的名称,例如 animationState,以提高代码可读性。
  1. 代码性能:
  • 当前实现已经考虑了动画状态,避免了不必要的处理,这是性能上的一个优点。
  • 但是,频繁的属性设置 setProperty 可能会对性能产生影响,建议考虑是否可以在适当的时候缓存这个值。
  1. 代码安全:
  • 当前代码没有明显的安全问题。
  • 建议在使用 st 变量前添加空值检查,以防止潜在的空指针异常。

改进建议:

// 改进后的代码示例
bool ChameleonStyle::hideScrollBarByAnimation(const QStyleOptionSlider *scrollBar) const
{
    // ... 其他代码 ...

    // 获取滚动条动画状态
    QAbstractAnimation::State animationState = QAbstractAnimation::Stopped; // 默认值
    if (auto animation = qobject_cast<QAbstractAnimation*>(sbar->property("_d_dtk_scrollbar_animation").value<QObject*>())) {
        animationState = animation->state();
    }

    bool isHoveredOrPressed = hoveredOrPressed(scrollBar) || sbar->underMouse();
    if (isHoveredOrPressed && animationState == QAbstractAnimation::Running) {
        // 标记一下,鼠标移开时需要重新开启隐藏动画
        sbar->setProperty("_d_dtk_scrollbar_visible", true);
        return false;
    }

    // ... 其他代码 ...
}

这个改进版本:

  1. 明确定义了 animationState 变量

  2. 添加了对动画对象的类型检查和状态获取

  3. 使用了更具描述性的变量名

  4. 提供了默认值,确保代码健壮性

  5. 其他建议:

  • 考虑将动画对象的获取和状态检查封装为一个单独的辅助函数,以提高代码的可维护性
  • 可以考虑添加日志记录,以便于调试和追踪动画状态变化
