Qt："Q3DScatter"即使包含在内也无法识别

Qt: 'Q3DScatter' not recognized even though it is included

本文关键字：包含在内 识别 Q3DScatter Qt      更新时间：2023-10-16

我想在我的主窗口中显示一个3DScatter图。

在我的mainwindow.h中，我包含了#include <Q3DScatter>但是当在 MainWindow 类的公共3DScatter scatterGraph;：部分时，我收到以下错误消息：

error: unknown type name 'Q3DScatter'

这是我已经检查过的内容：

在Qt
  • 维护工具中，已经安装了"Qt数据可视化"模块
  • 没有错误#include <Q3DScatter>
  • 当转到工具->找到并输入"Q3DScatter"时，它会找到Q3DScatter和q3dscatter.h
  • q3dscatter.h存在名为Q3DScatterPrivate和Q3DScatter的类
  • 在.pro文件中，第一行是QT += core gui datavisualization

我做错了什么？该模块似乎存在，但为什么我无法创建Q3DScatter scatterGraph？

编辑： 这是来自编译输出的完整错误消息：

快速浏览标头表明Q3DScatter是在命名空间QtDataVisualization下声明的。 在这种情况下，您需要使用...

QtDataVisualization::Q3DScatter scatterGraph;
