JScrollpane

[sandeep mathur]

Hi,

Can someone please explain me how JScrollPane works. In JScrollPane we use ComponentListener which has the callback method which sets the scrollbar position.
Here I am not able to understand that how do we generate the event which causes the ComponentListener to readjust the scrollbar.

Thank you.

You do not need to explicitly fire an events. Just wrap your component inside the JScrollPane embed it inside the container and you are all set to go.
In case you haven't done so, it might be a good idea to read http://java.sun.com/docs/books/tutorial/uiswing/components/scrollpane.html

Hi Maneesh,

Thanks for the reply.

Actually, I am writing a custom Scroll pane similar to JScrollPane. I have added the ComponentListener to the view of scrollpane. But, I am not able to understand how the events will be fired.
I have added the JList in the scrollpane but it is not scrolling. Should I change the y position of the list to generate the ComponentListener callback which will readjust the scrollbar postion.

Thanks,
Sandeep
