QString、QLatin1String、QStringLiteral QString QString: QString提供了一个Unicode字符串，QString存储的是一串QChar,而QChar...---- QStringLiteral 但是，函数只能接受QString类型的参数时，无论我们给一个字面字符串或QLatin1String,都会隐式构造一个临时的QString对象，构造这个对象需要在栈上申请一定的内存空间...此时，我们可以使用QStringLiteral来减小这个开销。 QStringLiteral其实是一个宏，从字符串常量创建QString对象的宏。...宏在编译时，从字符串文字生成QString数据，QString的内部数据将在编译时生成，在运行时不会发生任何转换或内存分配，使用QStringLiteral来代替C++中的双重数值传递将会在编译的时候显著的提升运行效率...**优点:**使用QStringLiteral而不是双引号的普通C++的字符串可显著加快从编译时已知的数据创建QString示例的速度，相对来说有QLatin1String参数重载的比使用QStringLieral

解决这个问题也很简单，在你输入中文的地方，用 QStringLiteral 宏包裹一下就可以了，代码如下： void MainWindow::on_showMessage_clicked() {...QMessageBox::information(nullptr, QStringLiteral("提示"), QStringLiteral("这是一个中文的提示，来测试是否有错误。"))...这样你就不用担心了，你可以随意输入中文在代码中，但记得要用 QStringLiteral 宏包裹一下。 Post Views: 9 相关
