QtCreator生成的新QML项目在Windows下不显示QML内容。

以下是我所做的：

  • I已经使用QtCreator =>新建项目生成了一个项目.configuration.
  • I应用程序(QtQuick)--使用CMake作为构建系统的Scroll => --使用QtCreator构建的应用程序--已将构建的*.exe移动到一个新建的空文件夹中。
  • i调用了C:/ Qt /5.12.2/ have 2017_64/bin/wintiqt.exe QtCreatorScrollProject.exe --释放--qmldir=c:\Users\Documents\QtCreatorScrollProject部署项目旁边的Qt依赖项。

当我在我的开发机器上运行这个构建时，它工作得很好：

​

当我试图在新虚拟机上运行完全相同的应用程序时，会出现窗口，但是窗口中的QML内容是不可见的( ==可滚动列表没有出现)：

​

我猜想这是一个部署问题，所以我试着遵循以下指南：https://wiki.qt.io/Deploy_an_Application_on_Windows。我遵循以下步骤：“

将以下内容复制到C中：\部署

MyApp.exe的发行版

所有来自.dll的C:\Qt\5.2.1\mingw48_32\bin文件

来自C:\Qt\5.2.1\mingw48_32\plugins的所有文件夹

(如果使用QML) C:\Qt\5.2.1\mingw48_32\qml中的所有文件夹

“

实际上，我不得不为自己翻译成这些步骤：“

将以下内容复制到C中：\部署

QtCreatorScrollProject.exe的发行版

所有来自.dll的C:\Qt\5.12.2\msvc2017_64\bin文件

来自C:\Qt\5.12.2\msvc2017_64\plugins的所有文件夹

(如果使用QML) C:\Qt\5.12.2\msvc2017_64\qml中的所有文件夹“

但是即使在做了这些之后，这个应用程序也没有显示QML内容。

因此，我检查了这些附加的内容:更多的信息:这是应用程序在QML_IMPORT_TRACE=1中运行时的输出：

还有：“Windows的可访问性洞察力”应用程序显示有一些东西，只是看不见：

​

更多的信息：

contents)

  • the应用程序在Windows7 VM下运行良好(所有内容都出现，包括QML

  • 应用程序没有显示Windows8和Windows10 VM下的QML内容)

下面是Windows7 VM的上下文(如OpenGL扩展查看器所示)，其中确实显示了OpenGL内容：

​

下面是Windows10 VM的上下文(如OpenGL扩展查看器所示)，其中没有显示OpenGL内容：

​

我尝试了很多方法来解决这个问题:从更新所有的驱动程序，到尝试强制使用不同的渲染器。到目前为止什么都没起作用。

在Qt 6中，角不再存在。您可以在代码中强制OpenGL，在main.cpp的开头：

代码语言：javascript
复制
#include <QQuickWindow>
...
#if defined(Q_OS_WIN)  
    QQuickWindow::setGraphicsApi(QSGRendererInterface::OpenGL);  
#endif

详情请参见https://doc.qt.io/qt-6/windows-graphics.html。
