qml messagedialog闪退 can't find linker symbol for virtual table for 'QObject' QT6

这个问题可能是由于您的应用程序使用了Qt 6,但是您的代码或库仍然是使用Qt 5编译的。
在Qt 6中,QObject的虚拟表结构已经发生了变化,这可能会导致您的应用程序崩溃。为了解决这个问题,您需要将您的代码和库重新编译为Qt 6。
如果您的代码和库是由第三方提供的,您需要联系他们以获取Qt 6版本的更新。如果您自己编写了代码和库,则需要使用Qt 6重新编译它们。
另外,确保您的应用程序使用正确的Qt 6库和头文件,以避免可能的链接错误。

qml messagedialog can't find linker symbol for virtual table for 'QObject' QT6
This error usually occurs when you are trying to link against a library that was built with a different version of Qt than the one you are currently using. In this case, it seems that the library containing the virtual table for QObject is not compatible with Qt 6.
To resolve this issue, you can try the following:
1. Make sure that you are using the correct version of the library that is compatible with Qt 6.
2. Check if there are any conflicting libraries that might be causing the issue. Try removing unnecessary libraries and rebuilding your project.
3. Check if the library containing the virtual table for QObject is built with the same compiler and settings as your project.
4. If none of the above steps work, you can try rebuilding the library from source using the same version of Qt that you are using for your project.
I hope this helps! Let me know if you have any further questions.

这个错误可能是由于您在使用QML MessageDialog时没有正确链接到Qt库引起的。您可以尝试在项目文件(.pro文件)中添加以下行:
```
QT += qml quick widgets
```
如果您已经添加了这一行,那么请检查您的Qt安装是否完整,或者尝试重新安装Qt。如果问题仍然存在,请确保您的代码中没有任何拼写错误或语法错误,并且您正在正确地使用QML MessageDialog。
