这就是我上次提到过的基于 QGraphicsItem 的工具栏提示。这个创意是，它会显示已经在 KFileItem 中的基本数据信息以及启动 KIO job 来从后端获取剩余的信息。Dunno 很疑惑这个创意的实现的时间只有 0 秒钟──那仅仅就使用了 KFileItem::timeString() 函数。让我们看看吧~
Here is that QGraphicsItem-based tooltip I mentioned earlier. The idea is it will show the basic metadata already in KFileItem to start then launch a KIO job to get the rest in the background. Dunno why the creation time is 0 - that is just using KFileItem::timeString(). Have to look at that
它使用一个中心起点和当前的弹出动画，它可以在 X 轴坐标上 180 度至 360 度旋转，然后重置。这意味着它会以边缘面对这你平面显现，接着“打滚”。
It uses a center origin and currently has a popup animation that rotates on the X axis starting at 180 degrees, going to 360, then resetting. This means it starts out flat with the edge facing you then "flips" around.
感谢所有在视频中提出建议的人们！我仍然不确定我还需要实现什么──今晚我 google 搜索了很多──但还有很多其他建议，那些建议也非常令人欣赏。
As to all the suggestions on video cards people have made, thanks! Still not sure what I am going to get - lots of googling to do tonight - but any other suggestions people have would certainly be appreciated.
Edit: Found a Radeon 9250 AGP w/ 256Mb for $60USD right down the street. It's old enough to where I should still be able to use the free drivers, but newer than what I got now. Does anyone have any experience with this card using the Xorg drivers? I'm not looking for anything too fancy - just something stable that I can hack on QGLWidget without occasional freezing. I'm not much of a gamer so don't need top of the line performance, (otherwise I'd get a better card and use proprietary drivers), but being able to use a composition manager and Pete's OpenGL plugin with epsxe would be cool, too >:)
