Hi experts,
I have a desktop with internal frames, a menu bar and a toolbar. The internal frame hieght is incremented every time a button is pressed and a label added to it but I want it to stop growing in hieght once it reaches the limits of the desktop. How is this done?
thanks

Can you not use the getHeight() method?

Everytime it is incremented use the getHeight() of the desktop and compare the height with that of the internal frame.

Hi Friend;

I made an example same as I gave you before but this sample explanes the limitation part. It actually refresh the size on
every text entered but it limits it to up to 350 by 250 size, which you can use on your part. Just know the size of your
desired size and walla the limit will cut it down.
