problem with menu bar on linux/solaris

[raghu.227621]

hi I am facing a problem with menu bar on linux platform..
I am creating customized menus.....
When I resize the window to a lesser size some of the menus r overlapped by window.

Can any one help me out.....

Suppose my menubar has file edit view abc def help.....
if i resize my window t a lesser value

I am unable to view help def abc n so on as window size reduces......

I need some thing like if i resize window the menu items should be displayed in rows
file edit
view abc def
help

something like this......
Can any one please send me the solution for autoadjusting menu items on window resize on solaris.
