#include "mainwindow.h" #include <QApplication>int main(int argc, char *argv[]) {QApplication a(argc, argv);MainWindow w;w.show();return a.exec(); }2. 添加資源文件
2.1首先將資源導入到項目中
2.2右鍵項目 - 添加新文件 – Qt - Qt Resource File
2.3給資源起名稱 res
2.4Qt會生成res.qrc 文件
2.5右鍵res.qrc open in Editor
2.6添加前綴
2.7添加文件
2.8使用 “ : + 前綴名 + 文件名 ”
2.9可以設置別名，但是不建議，因為設置別名，原來的方式就不可用了
