"TextArea auto-scrolls to bottom only if no
appends are done before (what? peer i"


Name: mc57594 Date: 05/21/97


Run the application given below.

It creates two (almost) identical TextAreas, and then after
a button press, adds some lines to each. The only difference
in how they are created is that one is append()ed to just
after creation; one scrolls to the bottom to show new lines
as they are added, but the other does not.

// Java program follows ///////////////////////////////////////
import java.awt.*;
import java.awt.event.*;

public class Ta extends Panel {
        Button countB;
        TextArea t1, t2;

        public Ta() {
                add( t1 = new TextArea("",10,20) );
                add( t2 = new TextArea("",10,20) );

                t1.append("No scroll-to-bottom\n");
                // t2.append("No scroll-to-bottom\n");

                add( countB = new Button("Count") );

                validate();

                countB.addActionListener(
                        new ActionListener() {
                                public void actionPerformed(ActionEvent
e) {
                                        for (int i=1; i<=30; i++) {
                                                t1.append("i = " + i +
"\n");
                                                t2.append("i = " + i +
"\n");
                                        }
                                }
                        }
                );

        }

        public static void main(String[] args) throws Exception {
                Frame f = new Frame();
                f.add( new Ta() );
                f.pack();
                f.show();
        }
