I don't really(my code is a bit more complex) but basically all 
it boils down to is a UI with some nested widgets (an overlay, an 
box, and a box and one contains the eventbox which I added those 
callbacks on.

I think that something like

https://github.com/gtkd-developers/GtkD/blob/master/demos/gtkD/TestWindow/TestWindow.d

should probably work by just adding an eventbox somewhere and 
adding that code above.

If it doesn't exhibit the same behavior then it has something to 
do with my project and I could try to reduce it to a minimal 
example.
