[GTK2] Remove GTK 2.x support [EBZ#530841] ------------------------------------------ Key: ERT-667 URL: https://issues.jboss.org/browse/ERT-667 Project: Eclipse Release Train Issue Type: Task Components: Platform Reporter: Friendly Jira Robot Assignee: Eric Williams Labels: SWT, bzira TL;DR: Gtk 2.x bugs are not investigated anymore. Please submit Gtk3* show stoppers to Bug 527444 instead. Reason: Gtk 2.x is getting old and a number of underlying libraries are getting changes which are not tested with it anymore. The fact that it relies on Webkit 1.x API which is not shipped with newer Linux distributions makes the Browser component on GTK 2.x useless quite often. This makes it increasingly difficult to maintain it. Almost all new Linux distributions provide Gtk 3.x with Webkit 2. As such effort is focused on improving Gtk 3.x and Wayland support. Gtk 2.x-only bugs are set to have Priority of P5, indicating that bugs exist, but will not be investigated by committers. Patches welcome though! FAQ: 1) Question: "I rely on Gtk 2.x because of bug XYZ in Gtk 3x". Answer: Focus is on resolving any 'gtk3' show stoppers that you may be experiencing. If you have a bug that stops you from moving to Gtk 3.x, please mention it in the gtk3 show stopper tracker (below) and we will do our best to address the bug in question: Bug 527444 [GTK3] Umbrella bug for GTK3 showstoppers https://bugs.eclipse.org/bugs/show_bug.cgi?id=527444 2) Question: "Gtk3 doesn't look proper on my gtk3 theme" Answer: Unfortunatley we don't have the man power to test/fix eclipse against every Gtk 3.x theme out there. Further a lot of the Gtk 3.x themes are pretty buggy, such bugs are out of our control. 'Adwaita' (light & dark) which is the default Gtk3/Gnome theme is the recommended choice for best results. Note, Gtk underwent a lot of theming changes. Gtk 3.22 is currently the most stable for themes. Note, 'Oxygen-gtk' theme engine is know to cause a lot of breakage and Gtk currently doesn't support it either. This bug is in place to provide information on Gtk2 status.
