Hi, I have some plans to work on gtk glass backend, not necessarily in this order:
1) Unify WindowContextBase and WindowContextTop - those were separated for applet support that were removed 2) Remove gtk2 Support 3) Add gesture support 4) Rework AlwaysOnTop, exploring _NET_WM_STATE_ABOVE 5) Fix DND: JDK-8273379, JDK-8280383 Some depend on [1]. I don't promise I will finish all of them, but it's the intention. Comments are welcome. [1] https://github.com/openjdk/jfx/pull/915 - 8260528: Clean glass-gtk sizing and positioning code -- Thiago.
