Qt中禁用高DPI缩放：QCoreApplication::setAttribute(Qt::AA_DisableHighDpiScaling)的使用方法

"QCoreApplication::setAttribute(Qt::AA_DisableHighDpiScaling);应该在main函数的开头处加入。\n\n示例代码如下：\n\nint main(int argc, char *argv[]) \n{\n QCoreApplication::setAttribute(Qt::AA_DisableHighDpiScaling);\n \n QApplication a(argc, argv);\n \n // 其他代码...\n \n return a.exec();\n}
