相信大家都玩過2048把，下面是我用qt寫得2048小遊戲。

main.cpp
#include "Widget.h" #include <QApplication> int main(int argc,char** argv) { QApplication app(argc,argv); Widget w; w.setFixedSize(320,480); w.setWindowTitle("2048"); w.setWindowIcon(QIcon(":/2048.ico")); w.show(); return app.exec(); }
比起一大堆啰嗦的文字，我還是覺得代碼更靠譜。
