Hi all, it's been a while since I was active on this mailing list. Sorry for the long silence. I am still working with JavaFX and generally very happy.
However, a couple of days ago I noticed that direct touch support on Windows is broken on a surprisingly large number of devices since JavaFX 16. I tracked the problem down to a relatively naive attempt at distinguishing *direct* touch events (finger based touch) from *indirect* stylus/pen based touch events (which are basically just mouse events) which was introduced as part of fixing https://bugs.openjdk.org/browse/JDK-8249737 . The problem is that on a large number of touch devices without a pen, touch events are always reported as indirect. Examples are iiyama touch monitors (capacitive, multitouch) for Windows PCs .Those devices and even most Surface devices since the Surface Pro 3 (verified with Surface Pro 4, 7 and Studio) fall under that category. The unfortunate result is that only gesture based multitouch works as expected. I created a PR on GitHub that fixes the issue by introducing a boolean property to the Scene class. The proposed interface can be seen here: https://github.com/openjdk/jfx/pull/927/commits/0caf15712a7e2e4492e6c2b5bb13417a514e41a5 I tried to explain the reasons for this API proposal here: https://github.com/openjdk/jfx/pull/927 I fully understand that such a change cannot be introduced without prior discussion. But since it's very urgent for our company to get this fixed, I created the PR anyway. Just as a public draft. And we are documenting the changes that we introduced in our JFX build. In the meantime, our company will roll out a custom JFX build with the proposed API. What are your thoughts? Do you agree with the proposed API? Would you prefer a different solution?
