Add scrollbar in undecorated JFrame

Question

I am using a JFrame in a java application and I needed to have it undecorated, so I just set setUndecorated(true) . I am using 3 panels in frame. Top, left and right. All frames have setLayout(null) .

Now I want to add scroll bar in right panel. I tried every thing available but I can't get it. Is there any way that I can have scroll bar?

Answer 1

You can use a JScrollPane for that purpose.

It is a container that automatically provides scroll-bar if the contents exceed it's size.

Secondly, using setLayout(null) is a bad practice. Actually it is worse than a bad practice. You should avoid with all efforts you can muster.

Try using suitable LayoutManager .

Here is a nice tutorial for using them.
You can also have a look at Visual Guide to Layout Managers .

Good luck.
