推荐答案

您的代码中没有语言问题" .您只需要调用许多Qt API.可能是您使用的Qt版本与W7不完全兼容.

There are no "language issues" in your code. You just call a number of Qt API. May be the version of Qt you are using is not fully compatible with W7.

由于失败，我想您是说从未输入if -block .您应该在调试器中在此处中断，看看哪些子条件在Windows 7上不返回true .这可能是W7的QT问题，可能是代码中的错误，可能是因为您需要更新的QT版本，可能确实是任何东西.

By fail, I assume you mean the if-block is never entered. You should break there in the debugger and see which of the sub-conditions do not return true on Windows 7. It may be a QT issue with W7, it may be a bug in your code, it may be that you need an updated QT version, could be anything really.
