Git 原始碼管理

今天在研究Git ，發現真的比Subversion好用太多了。
不過可惜的是只支援Linux 和Mac，windows要用msysgit。

剛好找到一篇非常詳細的中文教學

Qt Opengl Splash Screen

Qt 啟動畫面（Splash Screen）

#include <QtGui/QApplication>
#include <QMainWindow>
#include <QPixmap>
#include <QBitmap>
#include <QSplashScreen>

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

    //啟動畫面
    QSplashScreen *splash = new QSplashScreen;
    //顯示圖片
    QPixmap px(":/res/logo.png");
    splash->setPixmap(px);
    //遮罩圖
    splash->setMask(px.mask());
    splash->show();

    QMainWindow w;
    w.show();

    //如果w顯示出來的話，才關閉啟動畫面
    splash->finish(&w);
    delete splash;

    return a.exec();
}
