Johan can comment on the details, but I think that is a matter of
investigation.
As with the AWT work which is under discussion, there are two related,
but different deliverables that should be looked at:
1. Running the existing JavaFX GTK port on Wayland in X11 compatibility mode
2. A native JavaFX Wayland port
For both of them, we need a solution to the same "robot" problems that
AWT and other libraries face (there is no standard way to control the
mouse or to read pixels from the screen).
The fact that we already use GTK for most things should make #2 easier,
and it might be able to share a lot of the code, but it very likely will
need to be its ow backend, since it can't use X11.
In thinking out loud, one thing to consider might be to have a single
glass GTK platform with different native libraries for Wayland and X11,
since we already have that support to handle gtk2 and gtk3. Maybe
something like:
gtk2 (legacy and only for X11)
gtk3-x11
gtk3-wayland
gtk4-x11
gtk4-wayland
Not sure whether that makes sense or not.
I imagine that 1 should be feasible in the JavaFX 18 time frame. A
native Wayland port will be a lot of work, but since JavaFX already uses
GTK for most things, it should be significantly less work than AWT will be.

Hi Johan,
Would you prefer a pure Wayland backend or support it with gdk/GTK on top
of the current glass backend?
Cheers

I think we (everyone committing/reviewing in openjdk/jfx) did a great job
with the 17-work: an impressive amount of old and annoying bugs are fixed.
For 18 and beyond, I believe we have to keep working on those old issues --
at least if they are still relevant.
Also, I am 100% ok with the list of issues Kevin mentioned that need to be
moved forward now.
Apart from that, I want to have support for Metal and Wayland in JavaFX 18.

Now that JavaFX 17 is in RDP2, we can turn more attention to bug fixes
and enhancement requests for JavaFX 18. It's the summer, so there may be
delays as some people are out at various times (including me), but I
would like to get some of the outstanding enhancement requests moving
over the next few weeks.
Specifically, I'd like to see the following proceed:
* Transparent backgrounds in WebView
JBS: https://bugs.openjdk.java.net/browse/JDK-8090547
PR: https://github.com/openjdk/jfx/pull/563
* Add DirectionalLight
JBS: https://bugs.openjdk.java.net/browse/JDK-8234921
PR: https://github.com/openjdk/jfx/pull/548
* CSS pseudoclasses :focus-visible and :focus-within
https://bugs.openjdk.java.net/browse/JDK-8268225
PR: https://github.com/openjdk/jfx/pull/475
* Improve property system to facilitate correct usage (minus the binary
incompatible API change)
JBS: https://bugs.openjdk.java.net/browse/JDK-8268642
PR: https://github.com/openjdk/jfx/pull/590 (Draft)
And maybe the following:
* Add CSS themes as a first-class concept (need a consensus on how to
proceed)
* Undecorated interactive stage style (still in early discussion, but
the concept looks interesting and useful)
There are probably others I'm forgetting.
Each of the above should be discussed in their own thread on openjfx-dev
rather than a reply to this thread.
