为什么 Qt Creator 3.0.0 欢迎模式在 VM 中不起作用? [英] Why does Qt Creator 3.0.0 Welcome Mode not work in VM?

问题描述

我最初在我的 Win7 64 位机器上安装了 Qt 5.20 和 Qt Creator 3.0，它运行完美.然后我想将它安装到 Win7 32 位虚拟机中(使用 VirtualBox).在 VM 中，我从 qt-project.org 站点开始并下载一个版本.我已经尝试了 Qt Online Installer for Windows (13 MB) (Info) 链接和 Qt 5.2.0 for Windows 32-bit (MinGW 4.8, OpenGL, 689 MB) (信息) 链接.两个安装都可以工作，我可以编译一个简单的 Hello world 演示.但是，当 Qt 启动时，Qt 欢迎模式只是一个显示桌面内容的透明窗口.如果您更改模式并返回欢迎模式，它将只显示先前模式的内容.我想访问示例和教程链接.

I originally installed Qt 5.20 with Qt Creator 3.0 on my Win7 64 bit machine and it worked flawlessly. Then I wanted to install it into a Win7 32 bit virtual machine (using VirtualBox). In the VM I start off on the qt-project.org site and download a version. I've tried both the Qt Online Installer for Windows (13 MB) (Info) link and the Qt 5.2.0 for Windows 32-bit (MinGW 4.8, OpenGL, 689 MB) (Info) link. Both installs work and I can compile a simple Hello world demo. However, when Qt starts the Qt Welcome Mode is just a transparent window showing the contents of the desktop. If you change modes and go back to the Welcome mode it will then just show the contents of the previous mode. I would like to have access to the examples and tutorial links.

我使用的是 VirtualBox 4.3.6 并且安装了 Guest Additions.我正在运行 Win 7 Ultimate 的副本.VM 非常干净，它安装了 Chrome、最新的 Win 更新和 MS Security Essentials，仅此而已.安装后，虚拟硬盘 (vdi) 有大约 50 GB 的可用空间.

I'm using VirtualBox 4.3.6 and I have Guest Additions Installed. I'm running a copy of Win 7 Ultimate. The VM is very clean, it has Chrome installed, the latest Win updates and MS Security Essentials and that's about it. The virtual hard disk (vdi) has about 50 Gigabytes of free space after the install.

我试过了

1. turning off Windows Firewall and MS Security Essential real time protection. 
2. running as administrator.
3. running in xp SP2 and SP3, and win95 compatibility modes
4. running with Aero disabled

没有任何帮助.有什么建议吗?

Nothing has helped. Any suggestions?

推荐答案

我不是已知错误.Oracle Virtual Box 在呈现 QML 应用程序/小部件时出现问题.QtCreator 中的欢迎屏幕是一个 QML 小部件.https://bugreports.qt.io/browse/QTBUG-34964

I't a known bug. The Oracle Virtual Box has problems rendering the QML apps/widgets. And the welcome screen in QtCreator is a QML widget. https://bugreports.qt.io/browse/QTBUG-34964

解决方法使用 -noload Welcome 参数启动 QtCreator，稍后在 Help >关于插件... 菜单禁用欢迎"为好.

Workaround Start QtCreator with -noload Welcome argument, and later in Help > About Plugins... menu disable "Welcome" for good.
