Checkboxes with columnview

[themagicm]

I'm using gambas 2.16 on my linux box.  I'm importing a text file into a columnview and I want to be able to "check" (aka. select) which records I want by checking them or unchecking them.  Is this possible?  

EDIT:
In the meantime I think I got a work-around.  I created another field in the columnview and am fixing to add some code for when you "click" on a row, it changes the "X" (a check) to a "blank" (unchecked).  Kinda a lame workaround but might work.
