Hi, i'm trying to make an Messenger sistem, and whem i try to implement an
TextBox where goes the text wrrited by the user, the box has a scroll that
doens't follow the text that appears. So whem i want to read the last
messages sended i must scroll the Vertical Scroll bar with the mouse.
I send here some parts of the code.....
public class ChatBox extends Composite
{
final Text sendArea;
final Text recvArea;
Composite parent;
public ChatBox(final Composite parent, int style)
{
super(parent, style);
this.parent=parent;
GridLayout layout = new GridLayout(1,false);
layout.makeColumnsEqualWidth = true;
this.setLayout(layout);
GridData menuData = new GridData(GridData.FILL_HORIZONTAL);
menuData.heightHint = 25;
ChatMenu chatMenu = new ChatMenu(this, SWT.MULTI);
chatMenu.setLayoutData(menuData);
GridData recvData = new GridData(GridData.FILL_HORIZONTAL);
recvData.heightHint = 130;
recvArea = new Text(this,SWT.SHELL_TRIM | SWT.H_SCROLL |
SWT.V_SCROLL |SWT.DOWN);
recvArea.setEditable(false);
Color white = new Color(null,255,255,255);
recvArea.setBackground(white);
recvArea.setLayoutData(recvData);
recvArea.setText(new String());

You can use a) Text.setTopIndex() or b) Text.setSelection() with
Text.showSelection() to programmatically scroll the text.
