想做一个启动画面，需要在启动画面上的右上，中间，右下显示文字。现定义了三个位置，但在实现时只显示了右下的文字。请问各位大大们，需要怎么写才能同时显示三个位置的文字？ 还有怎么设置这三个位置文字的大小？
部分代码如下：
QSplashScreen *splash=new QSplashScreen;
splash->setPixmap(QPixmap("./images/splash.jpg"));
splash->show();
Qt::Alignment topRight=Qt::AlignRight|Qt::AlignTop;
Qt::Alignment center=Qt::AlignCenter;
Qt::Alignment buttomRight=Qt::AlignBottom|Qt::AlignRight;
splash->showMessage(QObject::tr("Setting up the main window..."),topRight,Qt::white);
splash->showMessage(QObject::tr("Software"),center,Qt::white);
splash->showMessage(QObject::tr("AP Workgroup"),buttomRight,Qt::white);
MainWindow w;
w.show();
splash->finish(&w);
delete splash;
