A Scrolling Problem

Question

Hi all I have a little problem I wana get fixed...its a little bit long problem so better help me out with this:
A swing application that has four textfield which accepts pure string and saves it to a database..theres a button when clicked will show the first record in the database and displays exactly the record in the four textfield...now here goes my question:
How do you scroll 1 record at a time thru the database and display record 2,3,4,5 and so on until the last record and display it to the textfield assuming we have button labelled next? and how will you reverse the process assuming you have button labelled previous which when clicked will display 1 record at a time in the textfield until it reaches the first record? I can display the first and the last record but scrolling one record at a time, that i cant do...hope you can help me with this or maybe give me some thread to get some idea with this...thanks and God bless to all...

Answer 1

The other way of doing this, which may be easier, is the follwing
pane.getVerticalScrollBar().setValue(pane.getVerticalScrollBar().getMaximum());where pane is the scrollPane. This will scroll to the bottom of the text pane.
One other point, you may find it more efficient on memory if you added the new message using the document instead of creating a new string from the old text and the new text to add. E.g
instead of
textPane.add(textPane.getText() + "\n" + newMessage);use
Document doc =  textPane.getDoument();
doc.insertString(doc.getLength(), "\n" + newMessage, null);Hope that helps
