如果您希望进一步扩展 Qt，请查看 KDE。它也（实验性地）在 Windows 上可用。它增加了相当多的功能，但也增加了很多依赖项。
For plotting and technical purpose, there are Qwt and QtiPlot. There may be others, but often a self-made widget is faster, smaller, and better than what someone could find on the net (except qwt and qtiplot of course).
If you're looking to extend Qt a bit more, look into KDE. It is also (experimentally) available on Windows. It adds quite a bit of functionality, but also a lot of dependencies.

出于绘图和技术目的，有 Qwt 和 QtiPlot。可能还有其他的，但通常自制的小部件比在网上找到的更快、更小、更好（当然 qwt 和 qtiplot 除外）。
