Hello folks,

I am trying to resolve a problem* that only affects Ubuntu 16.04. The announcement to ctoss-project-issues said "All non EOLed Linux distributions are already on Gtk 3.24" - however Ubuntu 16.04 which is EOL in 2024 uses GTK 3.18. 

Do we (eclipse dev community) consider Ubuntu 16.04 EOL for Eclipse purposes. If so and if GTK 3.18 isn't really supported going forward I am a lot less likely to invest the time to fix this problem.

Yes, Supported OSes for Eclipse purposes are described at https://www.eclipse.org/projects/project-plan.php?planurl=http://www.eclipse.org/eclipse/development/plans/eclipse_project_plan_4_16.xml#target_environments .  If we go the path of supporting OSes as long as their providers do we would still had to support RHEL 6 (even 5) with their GTK 2.x till 2024.

 

* If you are interested: https://bugs.eclipse.org/bugs/show_bug.cgi?id=549013 is the problem I am trying to fix, the existing fix regressed other stuff ( see https://bugs.eclipse.org/bugs/show_bug.cgi?id=558536 and its dups ) so I have to back it out and try again. BTW I don't know for sure if it is a GTK problem or an Ubuntu global menu problem or some other interaction between everything.

My first guess would be global menu interaction. You may want to look (although we are not adding back support for 3.18) at Menu.gtk_hide/show as there is code guarded with OS.ubuntu_menu_proxy_get() != 0 - the work there might not be needed or not enough after changes in the menu proxy Ubuntu installs.

 

Thanks for your input,

Jonah

Hey everyone,

SWT min Gtk version is going to be bumped again this release (to require Gtk 3.20+). All non EOLed Linux distributions are already at Gtk 3.24.

We plan to bump Gtk requirement to 3.24 for September release too.

This is important step so SWT work on GTK4 can be started now and thus the needs of it being expressed to GTK devs on time so we don't end in the GTK3 situation when porting SWT to it was started only after GTK 3.0 was final thus leading to many hacks.

Work will be handled in https://bugs.eclipse.org/bugs/show_bug.cgi?id=561047 .
