假设你原有“AAA”在JTextArea里面显示了JTextAreajta;你可以获取到StringsrcCont=jtagetText();你要新加内容Stringappend="BBB";jtasetText(srcCont+append);

Java 在JList上的监听事件

import javaxswingevent;

jmport javaxswing;

public interface ListSelectionListener extends EventListener {

public void valueChanged(ListSelectionEvent e);

}

实现 valueChanged

实例

import javaawtBorderLayout;

import javaxswingJFrame;

import javaxswingJList;

import javaxswingJScrollPane;

import javaxswingeventListSelectionEvent;

import javaxswingeventListSelectionListener;

public class SelectingJListSample {

public static void main(String args[]) {

String labels[] = { "A", "B", "C", "D", "E", "F", "G", "H" };

JFrame frame = new JFrame("Selecting JList");

framesetDefaultCloseOperation(JFrameEXIT_ON_CLOSE);

JList jlist = new JList(labels);

JScrollPane scrollPane1 = new JScrollPane(jlist);

frameadd(scrollPane1, BorderLayoutCENTER);

ListSelectionListener listSelectionListener = new ListSelectionListener() {

public void valueChanged(ListSelectionEvent listSelectionEvent) {

Systemoutprintln("First index: " + listSelectionEventgetFirstIndex());

Systemoutprintln(", Last index: " + listSelectionEventgetLastIndex());

boolean adjust = listSelectionEventgetValueIsAdjusting();

Systemoutprintln(", Adjusting " + adjust);

if (!adjust) {

JList list = (JList) listSelectionEventgetSource();

int selections[] = listgetSelectedIndices();

Object selectionValues[] = listgetSelectedValues();

for (int i = 0, n = selectionslength; i < n; i++) {

if (i == 0) {

Systemoutprintln(" Selections: ");

}

Systemoutprintln(selections[i] + "/" + selectionValues[i] + " ");

}

}

}

};

jlistaddListSelectionListener(listSelectionListener);

framesetSize(350, 200);

framesetVisible(true);

}

实例二

import javaawt;

import javaawtevent;

import javaxswing;

import javaxswingevent;//由于ListSelectionEvent是swing的事件，不是awt的事件，因此我们必须import

//javaxswingevent。

public class JList7 extends JFrame implements ListSelectionListener

{

JList list = null;

JLabel label = null;

String[] s = {"美国","日本","大陆","英国","法国","意大利","澳洲","韩国"};

public JList7()

{

JFrame f = new JFrame("JList");

Container contentPane = fgetContentPane();

contentPanesetLayout(new BorderLayout());

label = new JLabel();

list = new JList(s);

listsetVisibleRowCount(5);

listsetBorder(BorderFactorycreateTitledBorder("您最喜欢到哪个国家玩呢？"));

listaddListSelectionListener(this);

contentPaneadd(label,BorderLayoutNORTH);

contentPaneadd(new JScrollPane(list),BorderLayoutCENTER);

fpack();

fshow();

faddWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent e) {

Systemexit(0);

}

});

}

public static void main(String args[])

{

new JList7();

}

public void valueChanged(ListSelectionEvent e)

{

Systemoutprintln("eeee");

int tmp = 0;

String stmp = "您目前选取：";

int[] index = listgetSelectedIndices();//利用JList类所提供的getSelectedIndices()方法可得到用户所选取的所有

for(int i=0; i < indexlength ; i++)//index值，这些index值由一个int array返回

{

tmp = index[i];

stmp = stmp+s[tmp]+" ";

}

labelsetText(stmp);

}

}

java中如何获取JList的值

有一个JList列表框，当双击Jlist中的某一项的时候，就会把此项的值Print出来。我已经实现了双击，怎么来获取值？

public Object getSelectedValue()用这个方法可以获得选则的值

Java JTextArea 的使用

package JTextArea;

import javaawt;

import javaxswing;

public class TextAreaDemo extends JFrame {

private DescriptionPanel descriptionPanel=new DescriptionPanel();

public static void main(String[] args) {

TextAreaDemo frame=new TextAreaDemo();

framepack();

framesetDefaultCloseOperation(JFrameEXIT_ON_CLOSE);

framesetTitle("林泉居士");

framesetVisible(true);

}

public TextAreaDemo(){

descriptionPanelsetTitle("Canada");

String description="The Maple Leaf flag\n\n"+

"The Canadian National Flag was adopted by the Canadian "+

"Parliament on October 22,1964 and was proclaimed into law "+

"by Her Majesty Queen Elizabeth II (the Queen of Canada) on "+

"february 15,1965The Canadian Flag(Colloquially known "+

"as The Maple Leaf Flag) is a red flag of the proportions "+

"two by length and one by width,containing in tis center a "+

"white square,with a single red stylized eleven-point "+

"mapleleaf centered in the white square";

descriptionPanelsetDescription(description);

descriptionPanelsetImageIcon(new ImageIcon("image/agif"));

thisgetContentPane()setLayout(new BorderLayout());

thisgetContentPane()add(descriptionPanel,BorderLayoutCENTER);

}

}

class DescriptionPanel extends JPanel{

private JLabel jlblTitle=new JLabel();

private JLabel jlblImage=new JLabel();

private JTextArea jtaDescription;

public DescriptionPanel(){

panelsetLayout(new BorderLayout());

paneladd(jlblImage,BorderLayoutCENTER);

}

public void setTitle(String title){
