我来对这段代码进行审查分析:

  1. 代码逻辑改进:
  • updateSize() 函数中的改进很好:

    • 添加了对 maximumWidth 的检查,防止对话框宽度超过最大限制
    • 使用 layout->totalHeightForWidth() 可以更准确地计算布局所需的高度
    • 保持了默认最小宽度和高度的设置
  • eventFilter() 函数中删除的代码:

    • 删除对 messageLabel 和 titleLabel 的字体变化处理是合理的,因为:
      • 这种处理应该由布局系统自动管理
      • 手动设置最小高度可能会干扰布局系统的正常工作
      • 简化了代码逻辑,提高了可维护性
  1. 代码质量改进:
  • 代码结构更清晰,移除了不必要的条件判断
  • 减少了代码重复,将高度计算统一交给布局系统处理
  1. 性能优化:
  • 移除了 eventFilter 中的字体变化处理,减少了事件处理的开销
  • 使用布局系统的高度计算比手动计算更高效
  1. 安全性考虑:
  • 代码改进后没有明显的安全隐患
  • 建议在 updateSize() 中添加对 layout 指针的有效性检查:
if (auto layout = q->layout()) {
    size.setHeight(layout->totalHeightForWidth(size.width()));
} else {
    // 处理没有布局的情况
}
  1. 其他建议:
  • 建议在 updateSize() 中添加对 size 的有效性检查,防止出现负值
  • 可以考虑添加注释说明为什么移除了 eventFilter 中的字体处理代码

总体来说,这次代码改进是积极的,使代码更简洁、更依赖于 Qt 的布局系统,减少了手动处理布局的复杂性。
