About using Qt to build an LEGO EV3 software

LEGO MINDSTORMS EV3 Education Edition software is built by NI who built labview, and EV3 software is much like labview software, Visual Programming.

I want to build a software like EV3 software, OS software is just a reference

My current thinking is 3 steps to build this software:

1.UI implementation(drag effect and other UI effects)

2.Turn graphics into code

3.Transfer code to EV3 brick && hardware communication

My problem is not about programming on LEGO MINDSTORMS EV3, is about how to build a software like LEGO MINDSTORMS EV3 Education Edition or Home Edition itself, and others can Visual Program on my platform. I plan to use Qt, but I cannot find a open-source prj to reference(UI is very important).

can u guys give me some suggestions plz, give me a open-source prj url or a related website can both be very helpful, thx very much!!

I want to build a software like this url http://img.blog.csdn.net/20150727182203357

I'm not sure if you want to create software like this on qt yourself or just find OS qt software that can allow you to program EV3. Anyway, for both of this cases looking at https://github.com/qreal/qreal might be useful (readme and docs are mostly in Russian but the code itself and compiled program are in English).

It is project on Qt that allows you to create your own visual languages and such. On top of that there is qreal::robots (TRIKStudio) which does exactly what you might want - it allows to visually program robots such as ntx2.0,ev3 and others and even has 2d simulator to test your programs.
