[Gambas-user] Populating multiple columns in a column view

[M0E Lnx]

I have a column view with 3 columns

| NAME | TYPE | SIZE |

I know how to use the columnview1.add() function to add an item to it.
But that only fills out the first column. ( 0 )
How do I go about filling in the rest of the columns?
using the .add() function again will add a new item below the last
one, but will not fill in information to columns ( 1 and 2 )
