JScrollPane help needed

[awan2]

hei,

I have a little problem with scrolling...i am trying to develop a chat applet...when i receive a new message...i append it to the bottom of already existing messages( just like msn or other chat clients)...

But when i append new message...scroll pane should be at the bottom...but it remains at the top...so i have to scroll down to see the new message...

I want it to work same as in TextArea for example... please help...my brain is going to explode soon..part of my source code is given below:

//****************************************
Panel upperPanel = new Panel();

upperPanel.setLayout(
new FlowLayout(FlowLayout.LEFT));

JEditorPane jt = new JEditorPane();
jt.setEditable(false);
jt.setContentType("text/html");
jt.setText("<H2> Welcome </H2>");

JScrollPane editorScrollPane = new JScrollPane(jt);
editorScrollPane.setVerticalScrollBarPolicy(
JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);

editorScrollPane.setPreferredSize(
new Dimension(250, 300));
upperPanel.add(editorScrollPane);

//*****************************************

i am not familiar with the JEditorPane class but most components of this type extends the JTextComponent class. so i'll bet you can use the getText() and setCaretPosition() methods.

i.e.:
component.setCaretPostion( component.getText().length() );

where component is your JEditorPane. i am not too sure if this should work since there might be an effect to the getText() method regarding the HTML content type that a JEditorPane handles. just give it a try...
