I see in the target environments that Eclipse 4.5 supports SUSE Linux Enterprise Server 11 which only has 2.14 according to the
package list. Aside from that, I think only supporting 2.18 and up sounds pretty safe. Will it be sufficient to help the GTK3 situation though? It sounds like it won't help the two examples you gave (using GdkRGBA and using cairo only to draw). I also wonder
how much time is really saved in testing, bug reporting and fixing for 2.10/2.14 if they are so old that it's unlikely that people use them. I can see that in the code it will remove quite a bit of branches so that's good for readability but will it make a
difference for the GTK3 support stability and make it easier to adopt new recommendations? I was under the impression that as long as 2.24 is supported, it will be hard to adopt most of the new ways of GTK3. But you probably know a lot more that I do about
the subject :)
By the way, is it completely ruled out to have two ports? The GTK2 port could remain almost untouched (critical bugs only) and the GTK3 port would be free to use all the new GTK3 stuff. I remember that for a while, there was both the Carbon and Cocoa port for Mac so people would be free to use the more stable one and "modern" development could happen on the Cocoa port without compromise. Eventually, Carbon was marked as unsupported and was removed recently without fuss.

Hi Tom, My mail seems to be misunderstood. This is not a proposal to drop GTK 2.x support (2.10 - 2.24) in general but to limit this support to only newer 2.x versions (aka 2.18+). With 2.18 being released 5 years ago[1] and being in strict maintenance mode for smth like last 4 years this is safe requirement. It also DOES not require any change in Mars target environments [2] and will satisfy even Luna [3]. So to make it clear GTK 2.18 up to 2.24 will still be supported. By bumping this minimum requirement we open the door for streamlining swt codebase as there are many changes that have happened (macros-> functions, struct access -> functions, etc.) which are the same for newer GTK 2.x (2.18-2.24) and GTK 3.x versions but we have different codepaths for older GTK 2.x versions (2.10-2.17). So this proposal will not affect the Swing problems in anyway.
