FlexGanttFX for JavaFX on iOS
This video shows FlexGanttFX (dlsc.com) running on iOS devices (iPhone 12 Pro Max and iPad Pro). This is made possible via GraalVM and Gluon. The UI is 100% responsive and scrolling is smooth and fast. If you see me clicking something a couple of times to trigger it then it is only because this demo was not designed for mobile, so buttons are small and functions are hard to trigger. But this is a pure UI design issue.
