关键摘要:

• 在代码更改中，新增的条件判断 window->wmClass() == "dde-dock" || window->wmClass() == "dde-shell" 可能需要更多的上下文来理解为什么需要同时检查这两个类名。如果这个更改是为了修复一个特定的bug，应该提供更多的背景信息。
• 检查 window->flags().testFlag(Qt::Window) 和 window->flags().testFlag(Qt::Desktop) 是否可以替换为 window->wmClass() == "dde-dock"，以简化代码逻辑。

是否建议立即修改:

• 是，需要提供更多的上下文信息来理解代码更改的目的，并确保更改后的逻辑是正确的。同时，应该考虑简化代码逻辑，提高代码的可读性和可维护性。
