#include <QApplication> #include <QLabel> #include <QPixmap> #include <QString> int main(int argc, char *argv[]) { QApplication a(argc, argv); QLabel *label; QPixmap *pixmap; QString picName; picName = "/home/hxp/S_Transform/v1.0/t2016.png"; pixmap = new QPixmap( picName ); label = new QLabel; label -> setPixmap( *pixmap ); label -> show(); return a.exec(); }
