Hello Embeddedt,
thanks for answering again. I wrote already a answer to your last comment, but it wasnt send as i saw now. I will try it with AC6, but its not the wish i had, because:
I watched near all GUI softwares which are out to have a actual IDE which i can make modern things without problems. Now i looked in many forums, and they wrote back, if i am a beginner, stay away from AC6, because to make a complete project which you want to connect to hardware is a way you dont want to go as beginner, because i would need addons, and would get into problems which have to find always a way around. Many said to me, its only a question of time till they also have to change to CUBE IDE, and if i want to do it right, i should start with CubeIDE so i dont have to learn 2 different IDEs.
Dont get me wrong, as i said, i only write down what others wrote me, its without own experience. And because CUBE IDE is there, i was asking if there is a way to work with it in combination with littlevgl. STEMWIN can work with it, but i dont like the designs i saw so far, Everything looks like it comes from the year 1990 till 2000. It doesnt look modern what i saw. The best GUIs came from LittlevGL, TouchGFX ( but they cant really connect it to hardware, and it makes still huge problems with CUBEIDE as i saw 2 weeks ago as a statement from the developer), and sure Embedded wiz. but they are expensive. So my question was, if i can do it with cubeide as i asked in the headline, to get in no trouble later when i have a gui to connect it to the hardware. Because to make the GUI isnt the problem. In TouchGFX it was very easy and looked really awesome. But to connect it to the hardware was or is still a huuuge problem with TouchGFX.
So please dont understand me wrong, i love to learn new things, and i dont give up when it becomes hard, but we are in 2019 and i ask my self why there is no video tutorial which makes it total easy to follow 
Sure the 1-4 steps are easy, but as you also said, it wasnt foundable. Google and youtube work better for videos than for text. The title is near not understandable for a beginner. I mean how should i know what does it mean in the title littlevgl/stm32f746_disco_no_os_sw4stm32/blob/master/README.md
… _no_os_sw4stm32/blob/master/…???
what is no_os? Operatiing system? On Screen?
what is Blob?
why there is MASTER?
This all is not beginner friendly.
When i get my project done i will make tutorials for littlevgl , beginner friendly. Because it looks really awesome in my opinion, and its free… a dream.
But first i have to understand it by my self. And as it is normal for a human when they got it to work and have a nice GUI and they show it as a video in youtube, they think i show my made GUI, which costs me a lot of time, why should i make it easy for them and make a video tutorial… , thats normal in our time, but to get tutorials. EASY tutorials, would be the WIN for littlevgl. Because arduino is only so successfully because there are millions of beginner friendly tutorials. Give them a F746 board and an easy tutorial, and you can get over them time so many more littlevgl fans… believe me or look in their forums why they all gave up. Thats the key. But anyhow, my english isnt good enought to explain that i am thankfull for your link, i will try it and will see if i have at the end a good GUI like in TouchGFX and then no way to get it work with the hardware
