> possible to get all controls display view similar to swing controls.
It's possible, but it would be a lot of work to do well.
You would need to create a css stylesheet which mimics a given Swing look and feel.
The solutions are JavaFX css based, for which there are JavaFX css usage tutorials.
I do not advise using any of the solutions I linked earlier if you are having difficulty getting them to do anything at all. As I indicated, the linked projects do not form the comprehensive solution that you appear to be looking for. It would be a significant amount of work to provide a comprehensive solution. I strongly advise just sticking with the default caspian or modena css styles until you are more comfortable with the technology and prepared to make the time and investment to implement a comprehensive solution yourself.
