flash->setControl(QString::fromUtf8("{d27cdb6e-ae6d-11cf-96b8-444553540000}"));
flash->dynamicCall("LoadMovie(long,string)",0,"D:/Qt/qtcreator-2.4.1/projects/testswf/huaban.swf");
//flash->dynamicCall("WMode", "Transparent");
flash->dynamicCall("SetVariable(const QString&,const QString&)", "WMode", "Transparent");
this->setCentralWidget(flash);//主窗体加了背景色
