Description Eric Williams CLA 2019-03-29 13:39:59 EDT 
Run Snippet7 or Snippet8 on GTK4 -- scrolling the mouse wheel is not working.
Comment 1 Xi Yan CLA 2019-03-29 15:48:36 EDT 
I ran into a similar issue. Looks like it only works when mouse is focused on the scrollbar and gdk_event_get_scroll_deltas in gtk_scroll_event handler does not return delta anymore. Maybe the X/Y scroll delta can be retrieved from the "scroll" signal from GtkEventControllerScroll.
