[Github-comments] [geany/geany] Support changing tabs using mouse wheel for Gtk3 (#872)

[Luke Horwell]

I had a stab at (re)implementing this as I know the MATE Desktop project had this issue when migrating from GTK2 to GTK3.

https://github.com/lah7/geany/commit/5bfad0da637836b63d087b791e7b26ebcb512580

This only reinstates scrolling over tabs in the main editor. I'd consider the commit incomplete as all the other tabs (`notebook`?) like the sidebar and preferences should add the scroll event too but I'm terribly unfamiliar with C and didn't have much luck at this point. _Any help greatly appreciated._

But... it's a step towards having it back in GTK3 and doesn't impact the GTK2 build.

Scrolling over tabs is definitely part of my workflow. Too bad GTK3 requires each app to implement it separately. Unfortunately for me, as I switched distributions and finally made use of my HiDPI display, GTK2 is out of the question, _as much as I like GTK2._
