Adding JButton to JTextAreas

I'm publishing reports from data onto an uneditable JTextArea (so the user can save it as a text doc if they wish).
I'd like to have a button next to each report so the user can view the data for that report, but presumably this can't be done on a JTextArea?
Anyone have any suggestions as to how I can have a 'View data' button, but still be able to save the text of the report?
Many thanks.

If you are trying to produce a panel that has a JTextArea and a JButton on it, that is relatively easy to do.
You cannot put a JButton into a text area but it is easy enough to put it either next to or below the text area and provide the functionality that you are looking for.

Using JCheckBox, JButton and JTextArea with JDBC

Hello shlumph and SoulTech2012.
thanks for the reply. I�m wondering do any of you have links to web pages that include tutorials and source code on using JCheckBox, JButton and JTextArea with JDBC. would any of you who have experience with using JCheckBox, JButton, JTextArea and JDBC together be able to give me a few tips on how to select certain data from a table using JCheckBox, JButton and display the data in a JTextArea? examples of such data could be CD/DVD/Game data - i want users of my video library system to be able to view CD/DVD/Game information by name, age category, type and year. Users should be able to click on a check box (e.g. view by name, age category, type or year) and press a button. What would happen then is that data from the Product table would appear in the text area (which could be placed beneath the check box + button inside a frame and/or panel).
Thank you very much for your help.

Adding JButton, JTextField to scroll pane...

I have developed an appln in which I have added JPanel to JFrame.
To this JPanel I m adding JButton & JTextField. But the JButton & JTextField are increasing dynamically in my appln[according to DBMS query]. So I wanted to use scrolpane or something like so that the window can be scrolled vertically to view all the components[JButton & JTextField]. I m developing this as a standalone appln.
Plz help..
Thanking in advance.

Thanx fouadk ,
But my problem still persists. Now though I m able to add JPanel to JScrollPane, but when the components in the JPanel increase than the height of the Pane, the components at the dowm are not visible unless I resize the window by manually dragging the corners. Actually I wanted to keep the size of the window constant and make use of the VERTICAL SCROLLBAR.
Plz help.
Thanking in advance.
Following is code:

Your public class extends JFrame so it is a JFrame. In your main method you create a new JFrame and try to add the enclosing class (a JFrame by extension) to it. So you can either:
1 — remove the JFrame extension from the class declaration and leave the code in the main method as—is:
public class PM2C implements ActionListener {or,
2 — leave the JFrame extension and remove the new JFrame instance in the main method.
public class PM2C extends JFrame implements ActionListener {
    public PM2C(String title) {
        super(title);
        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                System.exit(0);
        Container contentPane = getContentPane();
        JPanel panel = new JPanel();
        leftButton = new JButton("Leftt");
        leftButton.addActionListener(this);
        panel.add(leftButton);
        rightButton = new JButton("Right");
        rightButton.addActionListener(this);
        panel.add(rightButton);
        contentPane.add(panel, BorderLayout.SOUTH);
        setSize(600, 600);
        setVisible(true);
    public static void main(String[] args) {

Adding JButton in JList

Hi
I wonder if it is possible to add JButton in a JList? Or how can I produce a list of JButtons? Each button represents a person (an object), is there anyway to add listener to the buttons so i can get the person thats represnted by the button? I can decide in advance how many button ther will be...that depends on the number of person in the db.

Use a panel with a GridLayout. The Panel can be added to a JScrollPane. Read this section on "Layout Managers":

Adding Image to JTextArea

Hello All,
I need to add an Image to a JTextArea. Any ideas plz.
best wishes
Issac

But I have read that all Swing Components, which extend from JComponent >can have other components added to them, because the JComponent class >extends from java.awt.Container and thus have a add method. I tried using t>he add method, but it didnt work. So I tried it here.Don't believe everything you read!!!!! JTextArea is meant to be a simple editor and is not meant to handle what you are trying to do.

Adding actionlistener to JTextArea

I'm trying to add an actionListener to my JTextArea, so that when the user hits 'enter', the action occurs.
sort of like this:
JTextArea.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ??????) {
doSomethingToTextArea();
but I'm having problems (e.g. how to make enter the action event, and some problem that says JTextArea can't use actionlisteners???)
any ideas?
thanks,
n00bProgrammer

Like serveral of the more complex swing gadgets the JTextarea uses model/view architecture. In this case the model behind the textarea is a Document, and the text change listener needs to be added to the Document, not the gadget itself. i.e. area.getModel().addDocumentListener();
However JTextArea still inherits the methods of java.awt.Component including addKeyListener();

Adding JButtons to JTable

Hello all,
How can I add JButtons to a JTable?
I found an article that is supposed to show you how to do just that:
http://www.devx.com/getHelpOn/10MinuteSolution/20425
I downloaded the code in the article and it works to an extent - I can see the buttons in the table but the buttons seem as if they are disabled :( Since I used this code in my application, I get the same behavior too.
Is there a bug in the code? Is there a simpler solution? What am I missing?
Raj

Thanks. That makes the button clickable. But now the button changes back to it's old value when you click on another cell. I suppose that's because we have 2 buttons, one for rendering and one for editing. So I added a setValueAt(Object value, int row, int column) to MyModel. This works throws class cast exception.

Adding JButton to JScrollPane

Hi there,
Just a quick request to look at this piece of code and see what I might be doing wrong... I'm trying to add a JButton to the bottom left of a JScrollPane using this code...
private JScrollPane resultsPane;
private JTextArea resultsArea;
private JButton saveResultsButton;
Container container = getContentPane();
resultsPane = new JScrollPane(resultsArea);
resultsPane.add(saveResultsButton);
container.add(topPanel) // this is a JPanel containing 2 other panels...
container.add(resultsPane, Borderlyout.SOUTH);The problem is that my 'saveResultsButton' is simply not being displayed. Anyone have any idea from this code what my error could be?
Any help appreciated.

Container container = getContentPane();

You probably don't want to add a JButton to the JTextArea either! Create another JPanel and add(resultsPane) to it then add(saveResultsButton) to it. Then add the JPanel to the container.

Adding JButton in a JTable

hi
i know this has been discussed quite a number of times before, but i still couldn't figure it out..
basically i just want to add a button to the 5th column of every row which has data in it.
this is how i create my table (partially)
     private JTable clientTable;
     private DefaultTableModel clientTableModel;
private JScrollPane scrollTable;
clientTableModel = new DefaultTableModel(columnNames,100);
          clientTable = new JTable(clientTableModel);

          tblColumn1.setPreferredWidth(70);
          tblColumn1 = clientTable.getColumn("Given Name");
          tblColumn1.setPreferredWidth(300);
          tblColumn1 = clientTable.getColumn("Address");
          tblColumn1.setPreferredWidth(350);
          tblColumn1 = clientTable.getColumn("Card Serial");
          tblColumn1.setPreferredWidth(100);
          tblColumn1 = clientTable.getColumn("Print Count");
          tblColumn1.setPreferredWidth(70);
          tblColumn1 = clientTable.getColumn("Print?");
          tblColumn1.setPreferredWidth(40);
          clientTableModel.insertRow(0,data);
          //clientTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
          scrollTable = new JScrollPane(clientTable);and i call this function void listInfoInTable(){
          JButton cmdPrint[];
          Vector columnNames = new Vector();

How do I add JButton to the 5th column of each row? This documentation here http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#width says that i need to implement TableCellEditor to put JButton in the table. How do i really do it? I want the button to call another function which prints the data from the row (but this is another story).
Any help is greatly appreciated. Thanks

you would need CellRenderer i think that it is in
javax.swing.table.*;
see if you can get started with that.
Davidthanks, i'll try and have a look at it
Yes, that's definitely what you need to start with,
but you also need a CellEditor to return the
button as well, otherwise the button will not be
clickable (the renderer just paints the cell for
display, it doesn't allow you to interact with it).
You could maintain a list of components for rendering
each cell of the table so that your
CellRenderer and CellEditor always
return the same object (i.e. a JButton for any
given cell).
CB.thanks for the info.. could you point me to some examples? is sounds quite complicated for me....
thanks again

Adding JButton onto a Rectangle

Hi All,
Is there any way to add a JButton onto the Rectangle..???
I have drawed a rectangle by using Graphics class and i need a button to be embedded onto that.
Thanks in advance.
regards,
Viswanadh

A Rectangle is not a Component so no you can't "add" it to a Rectangle.
Is the Rectangle the same size as the button so only one button fits in the rectangle. Or do you have multiple buttons in the Rectangle.
In the first case you could just add a Border to the button. In the second case you add a Border to a JPanel and then add the buttons to the panel.
I suggestion you start by reading the [Swing tutorial|http://java.sun.com/docs/books/tutorial/uiswing/TOC.html]. Maybe the section on Layout Managers so you learn how to control the positioning of Components in a Container.

I'm trying to add a JButton to my JApplet using the following code, I can't seem to figure out what's wrong.
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class Driver extends JApplet implements ActionListener
JButton easy;
public void init()
easy = new JButton("Easy");
getContentPane().add(easy);
easy.setBounds(0,0,0,0);
public void start()
public void stop()
public void paint(Graphics g)
public void destroy()
// For the ActionListener interface.
public void actionPerformed(ActionEvent event)
}

You can use those codes below:
import java.awt.*;
import javax.swing.*;
public class SwingWindow extends JApplet
     public SwingWindow()
     Container contentArea=getContentPane();
     FlowLayout flowManager=new FlowLayout();
     contentArea.setLayout(flowManager);
     JButton playButton=new JButton("Play");
     JButton stopButton=new JButton("Stop");
     contentArea.add(stopButton);
     contentArea.add(playButton);
     setContentPane(contentArea);
}
