Issue
How to force javaFx application use gtk3 libs? I know that SWT allows to set SWT_GTK3=1 environmental variable for that purpose. Is there any similar possibility / workaround for javaFx?
Solution
New feature (8087516: Conditional support for GTK 3 on Linux) allows using either GTK v2 or 3 with JavaFX. The default has not changed: GTK 2 will be used by default.
Switch GTK versions by setting the following properties:
// Output the version detected and used
-Djdk.gtk.verbose=true
// Toggle the preferred version to GTK 3
-Djdk.gtk.version=3
More details can be found on the OpenJDK mailing list thread.
Previous versions of JavaFX used GTK2 libraries. See the related issue for details. JavaFX bugs are now at:
- https://bugs.openjdk.java.net/browse/JDK-8088966 (closed as duplicate)
- https://bugs.openjdk.java.net/browse/JDK-8089584 (open)
The last issue has a comment:
Since mixing GTK2 and GTK3 in the same application causes this problem, we might have to deliver two native libraries, one for GTK2 and one for GTK3.
