GEF 5.1.0 compatibilty with gtk3 [message #1818442]

Hi All,

I am working on a product which is based out of Eclipse 4.12 (Pre-requisite is GTK 3), and using GEF 5.1.0.

While using GEF features of the product in Linux, software was crashing.
Then I tried passing --launcher.GTK_version = 2 option for launcher. This has solved the crash issue but its giving way to other issues.

Hence, I want to ask following questions.
Is GEF 5.1.0 compatible with GTK 3 ?
If not, what is the work around for this ?

Thanks and Regards,
Giri

Which Java version are you using? GEF itself does not have native artifacts, as such, the question of GTK compatibility is related to JavaFX alone. AFAIK it requires at least Java 9 to have proper support for GTK 3.

Thanks for the quick reply.

I am using Java 8. Does usage of FXCanvas widget has something to do with incompatibility with GTK 3 ?

Hi,

On Linux, I had to use Java 9+ to make it work past 2018-12. SWT dropped the support for GTK 2 at this point, and JavaFX only supports GTK 3 in versions 9+

So what you need is a consistent set of SWT/JavaFX versions: SWT < 2018-12 for GTK2 support, or JavaFX >= 9 for GTK3 support; then GEF should work.

HTH,
Camille

Hi Camille,

Problem is solved if I use Java 9. But the issue is, I need to stick to Java 8 due to some customer regulations.
Are there any specific widgets in JavaFX which needs Java 9, may i can find a replacement for those widgets which will work with Java 8.

Thanks,
Giri

When using GEF inside Eclipse, the JavaFX-SWT integration is employed. As Camille already pointed out, SWT dropped support for GTK2 with the 2018-12 release. On the other hand, JavaFX added support for GTK3 not before version 9. If you want to stick to Java-8, you will have to stick to GTK2 and thus to an oder version of Eclipse/SWT.
