Hide/Show hidden and system files

[Exolon]

Hi,

I'm very new to XY customization, so I would appreciate if someone could give me a helping hand.

I want to create a user defined button which enables me to hide/show hidden and system files in a fast way.
Currently I have to do this via (un-)checking the options in Tools->Configuration->General.

Is there a way to achieve this via scripting and a user defined button?

Thanks

Exo

Those buttons already exist in the toolbar:

Show Hidden Items
Show System Items
