JEP: JavaFX controls in the title bar

[Martin Fox]

Hi Michael,

Yes, this works! I wrote up a quick test app and it worked fine on the Mac. I’ll try to write up a more comprehensive app but might not get around to it for a few weeks.

Thanks,
Martin

That would require supporting multiple HeaderBarBase instances and providing an API to tell one to ignore leftSystemInset or rightSystemInset (or both). I like this solution since it allows the background visuals for each header bar to be customized.

A developer can add special items to the toolbar that track the dividers in an NSSplitView. I would let developers roll their own solutions if they want that design. Replicating that in JavaFX wouldn’t require any alterations to the HeaderBarBase class and it’s too specialized to be added to HeaderBar.
