Adding actions

[RiccardoPP]

Hi.

I'd like to add some actions to a nwg-wrapper to use it as a real desktop widget. For example, open a web link when I clicks or to change workspace with mouse wheel via swaymsg, etc. Is it possible?

Thanks for the code!

LOL, it was written for a guy who wanted to display the clock on his desktop. :)

Feel free to contribute if you can add what you want without breaking changes to the code.
