[PyQt] button delegate in a tableview

[Cristobal Infante]

Hi Erik,

Thanks again for your reply, It's good to know that at least I am making
some progress
with PyQt and have arrived to a dead end ;)

To be honest I am fine with it, will just have to explain my users they
will have to
activate the cell before clicking.

The important thing was to have my button clicking and that has been
achieved.

Thanks!
Cris
