This is a duplicate of #1778 #1815 #1848, but here is a solution. I see that in mate-appearance-properties the mouse scroll works very well like this:

#include <gdk/gdk.h> #if GTK_CHECK_VERSION (3,0,0) gtk_widget_add_events (GTK_WIDGET (notebook1), GDK_SCROLL_MASK); g_signal_connect (GTK_WIDGET (notebook1), "scroll-event", G_CALLBACK (capplet_dialog_page_scroll_event_cb), GTK_WINDOW (window)); #endif

[source](https://github.com/mate-desktop/mate-control-center/blob/master/capplets/app...) + [capplet_dialog_page_scroll_event_cb function](https://github.com/mate-desktop/mate-control-center/blob/master/capplets/com...)

I suffer from this GTK3 bug very much, too. Would you please describe where I can put this snippet to compile geany myself? Thanks!

You can add this where Geany create notebooks in source file, but I don't know where is it.

If somebody makes a Geany pull request it could be considered.

Note that it's not just the snippet pasted in the description, the whole function in @luigifab's 2nd link also needs to be implemented.

Yes, the entire function must be used, but it is included in a source file that uses the same license as Geany.

Yes, GTK has removed this user interface interaction, but it is useful, perhaps not for you. It's like menu icons, GTK 3 has spent time explaining to everyone that we need to delete them, and it looks like GTK 4 will delete them.

Same thing for the [treeview zebra/even-odd row styling](https://user-images.githubusercontent.com/31816829/81144172-ceb1ef00-8f73-11...), the possibility to use one color for even row and another for odd row from CSS, was removed. But for some people like me, it's useful.

About the proposed snippet, I tried new things. Since GTK 3.24 we can use GtkEventController, but the first scroll event is ignored (example links: [link1](https://github.com/luigifab/awf-extended/blob/a8489cda0196e473da4960e1a5d68e...) and [link2](https://github.com/luigifab/awf-extended/blob/a8489cda0196e473da4960e1a5d68e...) and [link3](https://github.com/luigifab/awf-extended/blob/a8489cda0196e473da4960e1a5d68e...), that's also true, I'm a noob in C language).

FYI, mouse wheel works fine with tabs in xfce-terminal.

This is partially fixed with [gtk3-classic](https://github.com/lah7/gtk3-classic).

Now fixed (I don't know why, but it's not very important), with [gtk3-classic](https://github.com/lah7/gtk3-classic) + geany v2.0.
