I've got the following code:
public class LobbyView extends JPanel
{
this.setLayout(new MigLayout());
private final JTextArea chatWindowMessage = new JTextArea();
private final JScrollPane chatWindow = new JScrollPane(chatWindowMessage);
LobbyView(Window sentWindow)
{
chatWindow.setViewportView(chatWindowMessage);
chatWindow.setPreferredSize(new Dimension(300, 300));
chatWindow.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED);
chatWindowMessage.setLineWrap(true);
chatWindowMessage.append("test" + "\n");
chatWindowMessage.append("test 2" + "\n");
this.add(chatWindow, "pos 180px 75px");
this.add(chatMessage, "pos 180px 380px");
}
}
The code results in the following JScrollPane:
How do I force the JTextArea to the bottom of the JScrollPane so it looks like this (NB I use MigLayout):
一种方法是根据JTextArea的行数在开头添加空白行,并使用setCaretPosition()方法将插入号位置设置为TextArea的末尾。
To force JTextArea
at the end of JScrollPane
, you can make use of Layouts. BorderLayout will do the job for you.
