Re: "click" event on a GtkSpinEntry

[cecashon aol com]

Hi Nicola,

This isn't pretty but it works.

There is a good read about the spin button at

https://blog.gtk.org/author/ebassi/

with Tim Bader on April 25, 2017. I don't know if you have seen that. My first try was just to get the 
GdkWindow of the spin button but that gave me the main window. No help there. Noticed that the cursor changed 
with the mouse movement so I went with that. Probably even more hackish than your solution.
