#include "mainwindow.h"
#include <QApplication>
#include <QSplashScreen>
#include <QTextEdit>
#include <QPixmap>
#include <QTest>       //需要在工程文件当中加入 QT += testlib

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QSplashScreen *splash = new QSplashScreen();
    splash->setPixmap(QPixmap(":/p_w_picpaths/lubuntu_logo.png"));
    splash->show();

   a.processEvents();      //这句话必须加上，不加的话，无法实现效果。

    //QTest::qSleep(3000);

    splash->showMessage(QObject::tr("Loading modules..."),
                            Qt::AlignCenter,
                            Qt::blue);
    QTest::qSleep(6000);

    MainWindow w;
    w.show();
    splash->finish(&w);
    delete splash;
