I'd like to achieve the following: A resizable JFrame class that has a panel of buttons on top and a JTextArea on the rest of the JFrame. It should look much like Notepad with buttons instead of drop down menus. So far I was able to write this, but the JTextArea resizes incorrectly.
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
public class TestDialog extends JDialog implements ActionListener {
public TestDialog(JFrame parent, String title, String message) {
super(parent, title, true);
JPanel buttonPanel = new JPanel();
JButton buttonOK = new JButton("OK");
buttonPanel.add(buttonOK);
buttonOK.addActionListener(this);
//Listing 2 goes here
add(buttonPanel, BorderLayout.NORTH);
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
JTextArea myTextArea = new JTextArea();
myTextArea.setText(message);
myTextArea.setName(title);
myTextArea.setLineWrap(true);
myTextArea.setWrapStyleWord(true);
JScrollPane myScrollBar = new JScrollPane(myTextArea,
JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
add(myScrollBar, BorderLayout.SOUTH);
setPreferredSize(new Dimension(1100, 800));
pack();
setLocationRelativeTo(null);
setVisible(true);
}
public void actionPerformed(ActionEvent e) {
setVisible(false);
dispose();
}
}
These are two closest hits: (JTextArea on JPanel inside JScrollPane does not resize properly) and (http://www1.cs.columbia.edu/~swapneel/1007/Notepad.java) However, in the first case the JTextArea resizes only to fit all text, not all available JFrame space. The second version version of Notepad doesn't have a scroll bar. As a result it doesn't work with large files.
Also, I have a lot of "overridable method calls in the constructor". I know this is bad. What should I do about it?
