Hi and welcome to devnet,
If you try to build that module with your distribution provided Qt, you need to install the additional packages that provide Qt's private headers.
You should also take into account that when you clone one of the modules, you get the dev branch by default which targets Qt 6.
I see an demo from qt website:
what I'm going to do is something like this demo. Dynamic data(wave) need to update to screen, The wave is scroll from left to right.
I'm curious what's the better wave to achieve this? Which widget would be the best?
I'm considering to custom a widget for partly update the window, but, not sure this is a good way.
Thanks advance if you a better idea.
