This part lies in a .java file and test lies in a fiel called test.java. I am having ig problems getting the tab to open this fiel when i click on it. Could i pleas get some help
Why are you starting a new thread to ask the same question? You where given the answer in your other thread:
http://forum.java.sun.com/thread.jsp?forum=57&thread=503438
The answer was: "Implement a ChangeListener"
If your new question is "How do I implement a Change Listener" then read this section from the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/events/changelistener.html]How to Write a Change Listener".

How can i place button on top right hand corner of the tabbed pane
Hi all,
i want to place button on top right hand corner of the tabbed pane, just run the code below, i have add button(it going to insert tab into tabbedpane), i want to place that tab into top right hand corner of the tabbedpane (not inside the tab itself). if i set tab policy setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT), it will give two button at right hand corner along with those buttons i want to and one more add button.
please suggest so that i can move forward.
Thanks in advance

Dayananda B VThis part of tabbed pane is not customizable as it lies in the ComponentUI(TabbedpaneUI) portion of the tabbedpane.
But I can point out the place u can change to bring the desired feature into effect.
U can find an Inner class called ScrollableTabSupport
Look for the methods createButtons where u can create extra buttons and add to the tabbed pane.
The Inner class also implements actionListener where u can implement the action for the button u added.
By this method U have to use your own extended TabbedPaneUI which u cant escape from.
Hope this will help u. -
How to a particular panel in a tabbed pane to the front?
Hello
I have a small application that uses a tabbed pane. At some point I want to press a button in one of the panels of the tabbed pane and then another panel in the same tabbed pane to show up, as if I had clicked on that tab to bring it to the front.
Only difference is I don't want to click on the tab to do it but on another button, so I can do some more stuff through the button before I bring the other panel to the front
I thought I could do this by getting focus, but it seems not to be the case. Getting focus does not mean coming to the front as I originally thought.
I hope this is clear. Here is an example that you can compile and run. I want to get jpanel2 to the front by clicking jbutton1 and vice versa.
Any help appreciated.

How to drag and drop tab nodes between tab panes
I'm working on example from this tutorial( Drag-and-Drop Feature in JavaFX Applications | JavaFX 2 Tutorials and Documentation ). Based on the tutorial I want to drag tabs between two tabs. So far I managed to create this code but I need some help in order to finish the code.
Source
tabPane = new TabPane();
Tab tabA = new Tab();
Label tabALabel = new Label("Main Component");
tabPane.setOnDragDetected(new EventHandler<MouseEvent>()
@Override
public void handle(MouseEvent event)
/* drag was detected, start drag-and-drop gesture*/
System.out.println("onDragDetected");
/* allow any transfer mode */
Dragboard db = tabPane.startDragAndDrop(TransferMode.ANY);
/* put a string on dragboard */
ClipboardContent content = new ClipboardContent();
content.put(DataFormat.PLAIN_TEXT, tabPane);
db.setContent(content);
event.consume();
What is the proper way to insert the content of the tab as object? Into the tutorial simple text is transferred. How I must modify this line content.put(DataFormat.PLAIN_TEXT, tabPane);?
And what is the proper way to insert the tab after I drag the tab:
Destination
tabPane.setOnDragDropped(new EventHandler<DragEvent>()
@Override
public void handle(DragEvent event)
/* data dropped */
/* if there is a string data on dragboard, read it and use it */
Dragboard db = event.getDragboard();
boolean success = false;
if (db.hasString())
//tabPane.setText(db.getString());
Tab tabC = new Tab();
tabPane.getTabs().add(tabC);
success = true;
/* let the source know whether the string was successfully
* transferred and used */
event.setDropCompleted(success);
event.consume();
I suppose that this transfer can be accomplished?
Ref javafx 2 - How to drag and drop tab nodes between tab panes - Stack OverflowI would use a graphic (instead of text) for the Tabs and call setOnDragDetected on that graphic. That way you know which tab is being dragged. There's no nice way to put the Tab itself into the dragboard as it's not serializable (see https://javafx-jira.kenai.com/browse/RT-29082), so you probably just want to store the tab currently being dragged in a property.
Here's a quick example; it just adds the tab to the end of the current tabs in the dropped pane. If you wanted to insert it into the nearest location to the actual drop you could probably iterate through the tabs and figure the coordinates of each tab's graphic, or something.

Disposable tabbed pane redrawing
Hi, i'm using disposable tabbed panes (with close button) in my program and i'm using following method to update their titles according to what user entered:
//this is class extending JPanel
public void updatePanelTitle(String newTitle) {
MainPanel panel = (MainPanel) getParent(); //MainPanel extends JTabbedPane
panel.setTitleAt(panel.getComponentZOrder(this)-1, newTitle);
repaint();
}Point is the title gets changed but the size of panel label does not. However, when i mouse-over the close button there, it gets changed to the size of the text.
@Override
public void mouseEntered(MouseEvent e) {
Component component = e.getComponent();
if (component instanceof AbstractButton) {
AbstractButton button = (AbstractButton) component;
button.setBorderPainted(true);
}setBorderPainted calls inside the repaint method.
Can anyone give a clue why it is not working or how to fix it?

}When you add instance of this to your JTabbedPane, you will get closeable Tabbed Pane with title you specified in addTab(title, component);
I implement method updatePanelTitle(String newTitle); to change the title of this tab when suer submits the data. These action controllers that call submitting and updating title are in controller package. Problem is that the title itself is changed when data are submitted but the <b>size of the tab is not adjusted to newTitles length.</b> It is just adjusted when i pull my mouse over the close button that implements action from previous post. It's in this class:

}I cant possibly post a running code as it uses third party libraries and implements bunch of interfaces, it would require whole nearly whole view-controller part of the project.
Another problem is that method getComponentZOrder(this) - 1, works for retrieving all tabs except the first one (it returns fine indexes for any tab but -1 for the first one) but sadly there is no such method like getIndex(Component) which would be useful for getting <b>this</b> components index.
Thanks in advance for ideas.

How do you undo pane tiling? Or get back to a tabbed pane?
One of our developers has managed to 'untab' 3 sql panes so they are appearing as 3 separate dockable panes. How do you take these 3 panes back into a tabbed pane (other than restarting SQL Developer)?
Message was edited by:
Andy RileyA "hidden" feature that not many people discover is that you can double click on the tab for a code editor, and it will maximize to take the whole of the main window. Double click its tab again, and it will shrink back to its original size.
Not exactly "tear-out" (which I agree would be nice... you should file that on the SQL Developer suggestion forum so that it winds its way back to the IDE team), but very useful if you have lots of code to edit :)

How to refrash tabbed pane at a run time
hi,
I have no practice in using tabbed panes, and now I have to solve a little problem. I am running internal frame wich contains tabbedpane. The tab which opens by default contains combobox which reads its data from DB. But when I open internal frame no data exists in a combobox.
Since I change the tab and select back again the same tab data combobox reads its data. I tried to validate the tab but nothing changes.
Where is my fault?The code that loads the data into the combo box is not being executed when you first create the internal frame. We can't tell you why since we have no idea what your code looks like.
So, trace the order of execution to see why the code is not executing. -

Image.setLocation(p.x-d,p.y-c); -
Have HTML content on Tabbed Panes
I'm trying to add HTML content to tabbed panes in an Applet environment.
Here is the code:
import java.awt.*;
import javax.swing.*;
<APPLET
CODE = tabbedpane.class
WIDTH = 400
HEIGHT = 200 >
</APPLET>
public class tabbedpane extends JApplet
public void init()
Container contentPane = getContentPane();
JTabbedPane jtabbedpane = new JTabbedPane();
JPanel jpanel1 = new JPanel();
JPanel jpanel2 = new JPanel();
JPanel jpanel3 = new JPanel();
jpanel1.add(new JLabel("This is panel 1"));
jpanel2.add(new JLabel("This is panel 2"));
jpanel3.add(new JLabel("This is panel 3"));
jtabbedpane.addTab("Tab 1",
new ImageIcon("tab.jpg"),
jpanel1, "This is tab 1");
jtabbedpane.addTab("Tab 2",
new ImageIcon("tab.jpg"),
jpanel2, "This is tab 2");
jtabbedpane.addTab("Tab three",
new ImageIcon("tab.jpg"),
jpanel3, "This is tab 3");
contentPane.setLayout(new BorderLayout());
contentPane.add(jtabbedpane);
Could anyone tell me how can i add html content to this panes?
Thanks

hai friends,
i am trying to create a tabbed pane which contains 3 panes.(top)
and i try to add a tabbed pane at bottom of first pane which is a panel.
i have set the size of panel as panel.setPreferredSize(new Dimension(750, 475));
Now i am finding i cannot view the tabbed panes added to the panel.
the relevant code is given below.
some one have any idea..
panel.add(new JScrollPane(textArea));
panel.add(new JScrollPane(table));
panel.setPreferredSize(new Dimension(750, 475));
panel.setBackground(Color.PINK);
JTabbedPane tabbedPane2 = new JTabbedPane (JTabbedPane.BOTTOM);
tabbedPane2.add("Result",new JTable(10,10));
tabbedPane2.add("Message",new JTextArea());
panel.add(tabbedPane2);
JTabbedPane tabbedPane = new JTabbedPane(JTabbedPane.TOP);
tabbedPane.addTab("name1", new JScrollPane(panel));
tabbedPane.addTab("name2",
new JScrollPane(new JTextArea(5, 5)));
tabbedPane.addTab("ANALYSIS", new JButton("< HAI ALL >"));
container.add(tabbedPane);
tabbedPane.setBackground(Color.ORANGE);i am giving the code i have done for the development of schema browser.
i have some what overcome the problem i have faced. but i know its not a proper way.
i am not able to use other layouts successfully to arrange these components.The layout now i have is not good enough.
may be because i am beginner.
kindly give your comments.....

Hiding tabbed panes-should be enabled only on certain event
Hi,
I desperately need help. I'm still new to swings and thus need help.I'm writing an swing application where i have tabbed panes just like a tree i.e
main1,main2
under main1 have have another set of tabbed panes. Now i have to enable only the first pane and inside that pane there is a button which should enable the other pane and so forth. I just cannot figure how i should go about doing it. Any help is appreciated.
ashahI tried doing that the new problem that i came across is that -
here is the sample of the code. This is on the similar lines like i have written the code
import javax.swing.*;
import javax.swing.event.*;
import java.awt.*;
import java.awt.event.*;
public class tabbedPaneDemo extends JPanel
JTabbedPane tabbedPane = new JTabbedPane();
JPanel panel1 = new JPanel();
JPanel mainPanel1 = new JPanel();
public tabbedPaneDemo()
Component panel1 = makePanel1();
tabbedPane.addTab("Panel1", panel1);
tabbedPane.setSelectedIndex(0);
setLayout(new GridLayout(1, 1));
add(tabbedPane);
Component makePanel1()
JButton next = new JButton("Next");
buttonListener listener = new buttonListener();
next.addActionListener(listener);
mainPanel1.add(next);
return mainPanel1;
class buttonListener implements ActionListener
public void actionPerformed(ActionEvent e)
if(e.getSource() == "Next")
tabbedPane.removeTabAt(0);
tabbedPane.addTab("Panel2",null,makePanel2());
tabbedPane.setSelectedIndex(0);
JButton next1 = new JButton("Next1");
buttonListener listener = new buttonListener();
next1.addActionListener(listener);
panel1.add(next1);
if(e.getSource() == "Next1")
tabbedPane.setEnabledAt(0,false);
tabbedPane.addTab("Panel3",null,makePanel3());
tabbedPane.setSelectedIndex(1);
Component makePanel2()
return panel1;
Component makePanel3()
JPanel mainPanel = new JPanel();
return mainPanel;
public static void main(String args[])
tabbedPaneDemo demo = new tabbedPaneDemo();
JPanel p = new JPanel(new BorderLayout());
p.add(demo,BorderLayout.NORTH);
JFrame frame1 = new JFrame("TabbedPaneDemo");
frame1.addWindowListener(new WindowAdapter()
public void windowClosing(WindowEvent e)
System.exit(0);
frame1.getContentPane().add(p, BorderLayout.CENTER);
frame1.setSize(400, 125);
frame1.setVisible(true);
I know there is a very simple mistake that i'm making but i can't figure where. -
Is there a way to add a listener to a tabbed pane in such a way that by activating a particular tab a sleeping thread wakes up? In particular, if I have an audio window on a tabbed pane, I want it to pause when that pane is not in focus and start when it is again activated.
Sure, read the JTabbedPane API and look for the add... methods to find a Listener you can add to your tabbed pane.

How Can I change TAbbed PAne Enabling Color ???
Default color is gray and it's not very nice ...
Thanks!Here it is with your line added. If this doesn't adequately demonstrate your requirements (the disabled tab color is orange), you're going to have to be a little more descriptive.
import javax.swing.*;
import java.awt.*;
class JTabbedPaneDemo extends JFrame {
public static void main(String[] args) {
new JTabbedPaneDemo().go();
void go() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(300, 150);
UIManager.put("TabbedPane.selected", Color.GREEN);
JPanel panel1 = new JPanel();
panel1.setBackground(Color.BLUE);
panel1.add(new JLabel("Foo"));
JPanel panel2 = new JPanel();
panel2.setBackground(Color.MAGENTA);
panel2.add(new JLabel("Bar"));
JTabbedPane tabs = new JTabbedPane();
tabs.addTab("Tab 1", panel1);
tabs.addTab("Tab 2", panel2);
tabs.setForegroundAt(0, Color.BLACK);
tabs.setBackgroundAt(0, Color.GREEN);
tabs.setForegroundAt(1, Color.RED);
tabs.setBackgroundAt(1, Color.ORANGE);
tabs.setEnabledAt(1, false); // Here you go, lazybones.
getContentPane().add(tabs);
getContentPane().setBackground(Color.YELLOW);
setVisible(true);

How can I make a tabbed pane transparent ?
I have a tabbed pane placed on a JPanel with an image background. I added a tabbed pane with tabbedPane.setOpaque (false), however I still can't see the image behind the components that were added as tabs in the tabbedpane. Any help will be greatly appreciated.
Here's a simplified version of the code:
public class Example extends JPanel {
public Example() {
tabs = new JTabbedPane();
tabs.setOpaque (false);
JPanel tp1 = new JPanel();
tp1.setOpaque(false);
tabs.addTab ("panel 1", tp1);
this.add (tabs);
public void paintComponent(Graphics g) {
// Paint background image
g.drawImage(...);
}Perhaps the opaque property is internally overset by the tab pane.
Try this:
public class Example extends JPanel {
public Example() {
JTabbedPane tabs = new JTabbedPane() {
public boolean isOpaque() {
return false;
JPanel tp1 = new JPanel() {
public boolean isOpaque() {
return false;
tabs.addTab("panel 1", tp1);
this.add (tabs);
public void paintComponent(Graphics g) {
// Paint background image
g.drawImage(...);
} Regards.
