My JOptionPane Scrolls to Bottom!

[AJArmstron@aol.com]

Hi. I have a JOptionPane which includes a JTextArea. I did this as I wanted to be able to control the size of the JOptionPane and have a scrolling feature. However, the problem is if the string which is imported into the text area is bigger than the defined areas then this causes the pane to scroll downwards so you see the bottom of the text imported. What I want is to see the very start of the string and the user then does not need to scroll upwards.

Can anyone help?

Many thanks.

I show my code below:
JTextArea area = new JTextArea();
area.setText(astringthatisimported);
area.setRows(25);
area.setColumns(40);
area.setEditable(false);
area.setLineWrap(true);
area.setWrapStyleWord(true);

JScrollPane scrollpane = new JScrollPane(area);

Object[] array = {new JLabel("This is the contents of your file."),
scrollpane, };

JOptionPane.showConfirmDialog(null, array, "This is the contents of your file.", JOptionPane.OK_CANCEL_OPTION);

Thank you very much for your post.

I tried doing this. However, I got the following error:

softeng2button.java:300: cannot find symbol
symbol : method setSelectedIndex(int)
location: class javax.swing.JTextArea
area.setSelectedIndex(0);
^
1 error

You write:
area.setSelectedIndex(0) or whatever the api is
I am not sure what you mean by api. Also I assume SelectedIndex is java coding and not the name of a field that I have defined?

I meant for you to look at JTextArea (Java 2 Platform SE v1.4.2) and see what exactly the methods are called.

Try "setSelectionStart()" and "setSelectionEnd()"

With setSelectionStart() I get the same message as before!


softeng2button.java:301: setSelectionStart(int) in javax.swing.text.JTextComponent cannot be applied to ()
area.setSelectionStart();
^
1 error

----jGRASP wedge2: exit code for process is 1.
----jGRASP: operation complete.


I note the API page makes no reference to setSelectedIndex(0)
However for setSelectionStart it says:

setSelectionStart
public void setSelectionStart(int selectionStart)

Sets the selection start to the specified position. The new starting point is constrained to be before or at the current selection end.
This is available for backward compatibility to code that called this method on java.awt.TextComponent. This is implemented to forward to the Caret implementation which is where the actual selection is maintained.


Parameters:
selectionStart - the start position of the text >= 0



When it says public void setSelectionStart(int selectionStart) does this mean that I have to somewhere include this line in the program?

Thank you. Using the line:

area.setCaretPosition(0);

..solved the issue!!!!
