现在Qt不要光看跨平台了,Qt也有能力和原生应用进行较量的.可以直接去Qt官网查看他和那些厂商合作.关于和Java的比较,框架和Java进行比较似乎不且实际.如果是C++和Java比较,网上有很多文章,可自行翻阅,不要在知乎上看C++和Java比较,黑了C++,捧了Python和PHP.Java呢?晾一边了.在安卓上的话,现在问题可能很多,但是随着Qt的更新,大体解决得七七八八了.Qt on Android 对于原有Qt开发人员和爱好者是一个不错的选择,虽然在Qt可以完成大部分安卓的对应功能,可…

QT与JAVA有点类似,也是一种跨平台的软件(当然在windows平台和linux平台需要安装相应的QT开发环境和运行库,类似于JAVA在不同平台下的虚拟机JVM环境),因此对于某些需要同时支持windows平台和linux平台的应用,QT也是一种不错的选择. QT在linux的开发环境相对简单,只要下载一个Qtcreator就可以轻松搞定:http://qt-project.org/downloads. 而对于Windows下熟悉VS开发的程序员来说,如何将QT与VS结合来开发需要遵循一定的步…
