[Gambas-user] Howto somewhat thicker GridView lines

[Rolf-Werner Eilert]

Just looked for a way to make some (not all) of the lines of a GridView 
somewhat thicker, for instance every second line or something like the 
line between Row 2 + 3 and Row 4 + 5.

Is there a way to achieve that?

Thanks for any hints!
