Proposal: could a .rb example file be added, to showcase event signal changes handling in ruby-gtk4? Just to show the new API that gtk4 uses here.

[rubyFeedback]

Heya kou,

I am currently experimenting with ruby-gtk4 now that it works (for me at the least).

The guide here mentions what has changed:

https://gitlab.gnome.org/GNOME/gtk/-/blob/main/docs/reference/gtk/migrating-3to4.md

::button-press-event            # -> [class@Gtk.GestureClick]
::key-press-event               # -> [class@Gtk.EventControllerKey]

Would it be possible to add examples that show the changed API?

The old events I used in ruby-gtk2 and ruby-gtk3 do not seem to work. I assume I have
to change it to Gtk::GestureClick and Gtk::EventControllerKey but I have not yet tried.

I may figure it out in the coming days. But I think it may be nice to add a widget that
could work in ruby-gtk3, and then in ruby-gtk4, to show what has changed in regards
to events.

Not all events have to be tested, but I believe the mouse-key-press event and the
keyboard-key-press event is very commonly used in application code, so it may
be nice to have just a small (really small) example, like the hello world example,
but just showcasing the event keys.

I'll try to figure it out on my own and then perhaps I will have an example that I can
add. Or perhaps someone else is faster. But I think for new users for ruby-gtk4
in particular it may be helpful to have a single .rb file that showcases a working
example of events. People can then adapt it in their own projects.

I agree with this.

I'm waiting for volunteers who want to working on this: #1489 (comment)
