[plt-scheme] on-paint event overriding ?!

Hi,

I am trying to draw some lines on a table (make-table). The fact is that when I lose the focus of the window (the table here...) all my lines disapear and only the cards (from the "cards.ss" library) are left on the table.

My question is : How can I "add" my code to the on-paint event for the "table". I know that I can override the event. But can I keep the default code and add my code to it  ?!?  How ?!?

Thanks in advance,
J-D.
