在VS上使用Qt库

Question

我正在尝试在VS上构建一个C ++项目。该项目是在Linux机器上使用NetBeans开发的，现在我在Windows上使用Visual Studio 2017。

它没有使用Qt Creatos开发，因此手动添加了库，例如：

#include <QtCore>
#include <QCoreApplication>
#include <QObject>
#include <QStringList>
#include <QMap>
...

这是我到目前为止所做的：

• 下载最后一个Qt版本
• 在C：\ Qt
中解压缩所有内容
• 在VS属性中＆gt; VC ++目录＆gt;包含目录 - 我添加了C：\ Qt \ Qt5.9.2 \ 5.9.2 \ msvc2017_64 \ include和C：\ Qt \ Qt5.9.2 \ 5.9.2 \ msvc2017_64 \ include \ QtCore
• 在VS属性中＆gt; VC ++目录＆gt;库目录 - 我添加了C：\ Qt \ Qt5.9.2 \ 5.9.2 \ msvc2017_64 \ lib

然而，当我尝试#include <QtCore>时，似乎VS期待更多： https://imgur.com/a/ruSbi

但它没有编译。

所以，我想我错过了一些东西。我是VS的新手，所以我很感激任何帮助。

谢谢

QtCore既是目录又是包含文件：

Directory: <Qt_Install_Path>/include/QtCore
File:      <Qt_Install_Path>/include/QtCore/QtCore

此外，您需要在包含moc宏的每个标头上运行Qt Q_OBJECT。 moc将生成额外的C ++文件，您需要编译它们。使用qmake或cmake等工具时相当简单。对于VS，您可能会使用Qt Visual Studio Add-in。
