## 概述
加载图片
```
QApplication app(argc, argv);
QSplashScreen *splash = new QSplashScreen;
splash->setPixmap(QPixmap(":/img/1.png"));
splash->show();
splash->showMessage( "Creating Widgets Page...",Qt::AlignHCenter | Qt::AlignVCenter,Qt::red);//居中，红色字体
app.processEvents(); //当处理的事件耗时较长时，保证所有事件处理完成后再继续往下执行
QThread::sleep(1);
splash->showMessage( "Creating Database Page..." );
app.processEvents();
QThread::sleep(1);
splash->showMessage( "Creating Games Page..." );
app.processEvents();
QThread::sleep(1);
MainWindow mainwindow;
QTimer::singleShot(2500, splash, SLOT(close()));
QTimer::singleShot(2500, &mainwindow, SLOT(show()));
return app.exec();
```
动态图
```
QApplication a(argc, argv);
//===动态程序启动画面===
QPixmap pix(":/resource/splash2.gif");
QSplashScreen splash(pix);
QLabel splashlabel(&splash);
QMovie splashgif(":/resource/splash2.gif");
splashlabel.setMovie(&splashgif);
splashgif.start();
splash.show();
splash.setCursor(Qt::BlankCursor);//不显示鼠标外观
for(int i=0;i<15000;i+=splashgif.speed()){
QCoreApplication::processEvents();
Sleep(splashgif.speed()/5);
}
// QCoreApplication::processEvents();
toolbox w;
w.show();
splash.finish(&w);//程序启动画面结束
return a.exec();
```
