hummm ... yeah man. That's exactually the point. After yout post, can
run again my program and I saw that the fisrt node was really created,
and when I click it , the other elements (childs) appear !! ;)

Now , I did what you say (populate the thee in the same level), and
every thing is working fine, except when I click in a element showed
-> I get a SEGFAULT !!

Any suggestions ?!

hummmm ... unfortunality, in the future, I will need a real tree structure ! :S

Best Regards (and thanks Santhosh) !
