Layouts with constraint classes

[Daniel Zwolenski]

More or less. I would have liked a really nice type safe Style Java API much like the really nice type safe Node API and Animation API, etc. Then CSS would be more of a higher level way of interacting with it (like FXML is to Nodes). This would allow nicer styling direct in java code eg something like:

    Style myStyle = new ButtonStyleBuilder().border(2).padding(10) 

And querying styles:

   ButtonStyle style = StyleSheet.resolveStyleFor(my button);
   style.getBorder().getWidth();

Or whatever, you get the gist. It would obviously be a lot more complex than I imply here but I'm tapping on my phone. 
             
This would also open the door to people building their own non-CSS style languages that map onto the java (eg json) or I could even put my styles in XML along side the FXML files, etc. I have use cases, but the main thing is its easier for developers to get creative when it's in java (as we just saw with Tom's unique FXML use case).   

This is an old conversation though, I've kicked it around many times. I don't think it's something likely to change so maybe not worth burning your time on? I'd rather see that blog post you were talking about on how you got jfx working on android :)
