QT5 Failed to load platform plugin "windows" 终极解决方式 命令行问题

Failed to load platform plugin "windows"

这个错误在双击exe运行时不会出现，当传递命令行參数时出问题 ，解决方法：

int main(int
argc,
char
*argv[])

{

Q_INIT_RESOURCE(rc);

//解决库路径问题============info@seatrix.com

QTextCodec *xcodec = QTextCodec::codecForLocale() ;

QString exeDir = xcodec->toUnicode( QByteArray(argv[0]) ) ;

QString BKE_CURRENT_DIR = QFileInfo(exeDir).path() ;

QStringList  libpath;

libpath << BKE_CURRENT_DIR+QString::fromLocal8Bit("/plugins/platforms");

libpath << BKE_CURRENT_DIR <<BKE_CURRENT_DIR+QString::fromLocal8Bit("/plugins/imageformats");

libpath << BKE_CURRENT_DIR+QString::fromLocal8Bit("/plugins");

libpath << QApplication::libraryPaths();

QApplication::setLibraryPaths(libpath) ;

//=========================

QApplication a(argc, argv);

MainWindow w;

w.show();

return a.exec();

}
