QDesktopWidget: No such file or directory 错误是因为无法找到QDesktopWidget相关的库文件或路径配置。为了解决这个问题,你需要在.pro文件中添加QT += widgets,这将包含QDesktopWidget所需的库文件。同时,确保在你的代码中包含了正确的头文件#include <QDesktopWidget>。

qdesktopwidget file not found
The error message "qdesktopwidget file not found" usually occurs when the Qt library cannot find the QDesktopWidget header file. This file is required to use the QDesktopWidget class in Qt applications.
To fix this error, you can try the following steps:
1. First, make sure that you have installed the Qt development libraries on your system. You can check this by running the command "qmake --version" in a terminal window.
2. If the Qt libraries are installed, then you should check whether the QDesktopWidget header file is included in your project. You can do this by opening your project file (.pro) and checking the "INCLUDEPATH" variable.
3. If the QDesktopWidget header file is not included in your project, you can add it manually by adding the following line to your project file:
INCLUDEPATH += /path/to/qt/include
Replace "/path/to/qt/include" with the path to the Qt include directory on your system.
4. Finally, you should try cleaning and rebuilding your project to make sure that the changes are applied.
If none of these steps work, you may need to reinstall the Qt development libraries or consult the Qt documentation for more information on using the QDesktopWidget class.
