Only one GtkEventControllerScroll per widget possible
In GTK3, it was possible to connect to ::scroll-event
of a widget. In GTK4 we should be using GtkEventControllerScroll
to do the same thing, but you cannot add one of those to a widget that already has one attached, since now the newer one will get the event while the older one won't. That means adding a second GtkEventControllerScroll
to a GtkScrolledWindow
will make normal scrolling completely impossible. Would be good to have a replacement for the ::scroll-event
behavior.
