    由于QT4.7.0不支持OpenGL的双缓冲画图,最近一直致力于寻找一个比较好的版本,于是试用了QT 5.1,不承想,却发现了它的两个Bug,现描述如下,希望后来者少走弯路。

    1、使用QFileDialog获取保存图片的文件名时,getFileName()函数在Win XP下无法获取扩展名,而在win7下没有问题。

    2、使用QMdiArea管理多文档窗口,在TabbedView模式下,当只打开一个窗口时,使用avtiveWindow()无法获取,closeActiveWindow()无法关闭;当打开多个窗口时,一切OK。

      谢谢分享,不过在Qt5.1中QFileDialog没有getFileName()函数,倒是有一个getOpenFileName()函数。
      1、如果的确需要获得扩展名的话,使用QFileInfo::suffix()结合QFileDialog即可。
      2、没有遇到过。
