Hey there,

Would it be possible to add a specific example for events?

That includes buttons - this is easy.

But it would be nice if more events could be showcased, such as
how to respond to mouse-click events in different widgets,
including a gtk entry and a gtk label.

And perhaps a few more examples.

This would be helpful for people who port older code from e. g. gtk3 to see
how things changed in regards to events. The new event model still
confuses me and is one reason I failed to transition into gtk4 so far.
