Aren't you on vacation too?? :-)
> I think there are a few things in standard FXML that are fairly dependent on Builders. I cant remember exactly and its hard for me to look up currently (there's no way to browse the OpenJFX source online is there?) but from memory often when I tried to port between FXML and code there were magic methods not available in the code so I assumed builders were the source.
I know there is some stuff in SceneBuilder (where it tries to determine the default value of a constructor parameter I think), I'm not sure how much of it leaks into FXML. I *think* they are separable for the core libraries but I'm not totally sure.
> e.g. can you create a colour in FXML directly, fonts, images? Stuff like that. I suspect at a minimum some of the tutorials will need updating to not use convenience builder methods.
These things end up using the "valueOf" methods that were added to the various classes IIRC
> Also, Im again guessing but for FXML to optionally use builders doesn't it need to have a dependency on the builder class? I suppose it could all be reflection based, avoiding the compíler dependency, but it would still be quite weird for the core JFX code to be looking for a class that is now effectively third party.
I think the Builder class itself would stay, but the various builders that we built would be deprecated.
