switching between frames

[phillip]

Hi,

I have a GUI that displays the contents of a properties file and
allows for a user to edit the values and rewrite the file.

But I have more that one file and want to display the values  on a
frame and then click a button to display the contents of the other
file.

When I try to insert the new labels and entry widgets they just append
themselves to the previous frame.

I also tried to start up new frames, but they just layered themselves
on top of each other.

Is there a way to set the visiblity of the frames so that i can
control which frame a user is seeing?
