Thanks John
The problem is: if i use approach #1, it will require mygui to be the class
variable in the UsingMyGui class(which i have mislead you in the example).

approach # 2, i don't think it is doable. because i don't have access to the
mygui variable.

what i am thinking about is having the operating system(ms windows) to
close/dispose it. Or is there a way to find out what is on display and use the
instanceof method to get the instance of MyGui, and close it that way?
Thanks
