JTabbedPane : JPanel transparent to 2D drawings
Hi.
I am using ptolemy/ptplot package for 2D graphics. I use a JTabbedPane to managae my plots by pages. Each plot is updated continuously by a Thread which get data from a datatbase.
The problem: when a plot is refreshed in a hidden Tab, the plot appears also in the selected Tab. Only
the data points appear, not the axes and the background. Result: I have a supperposition of "undesired
plots" on the selected Tab.
Please some one tell me how to solve this problem ?
N.B.: I don't have a real experience with Java 2D.
Christophe.
Hi.
I have found a workaround : my JTabbedPane now implements ChangeListener and "pauses" the plotting
when a new Tab is selected. Only the plots on the selected Tab are refreshed the other are "paused".
Thanks to hpsmartyz for the reply but I am new to Java2D, and I was not ready to modify the plot
package I am using and implements his solution.
Christophe.

How to make a JPanel transparent? Not able to do it with setOpaque(false)
Hi all,
I am writing a code to play a video and then draw some lines on the video. For that first I am playing the video on a visual component and I am trying to overlap a JPanel for drawing the lines. I am able to overlap the JPanel but I am not able to make it transparent. So I am able to draw lines but not able to see the video. So, I want to make the JPanel transparent so that I can see the video also... I am posting my code below

"How to Use Layered Panes"
http://java.sun.com/docs/books/tutorial/uiswing/components/layeredpane.html
Add your video component to one layer and your non-opaque panel to another layer.Did you try that with JMF? It does not work for me. As I said, the movie seems to draw itself always on top! -
In the application I am writing I want to allow for some popups on my interface. I am using a JLayeredPane, with two JPanels. The main JPanel, on the default layer, holds all the main components. A second JPanel, at the popup layer, will hold any components which should "pop up".
The layered pane is using a border layout, with both JPanels in the Center.
Unfortunately the bottom panel cannot be seen. It is covered by the top panel, even after I called setOpague(false) on the top panel.
Am I taking the wrong approach? Or is it just not possible to make a JPanel transparent?It should work.I have fiddled around, but have been unable to get this to work. It seems obvious that I'm doing something wrong. :( Below is an example which mimicks my real code, and hopefully is simple enough.
I appreciate any help you can provide.

Advice for JPanel transparency idea
Hi!
I've spent all day reading about the CardLayout and JLayeredPane and am confused as to which route to take.
Here's what I'm planning to build:
- One frame containing three panels.
- Each panel holds an invididual image and and stretches to the extents of the frame, thus the panels sit on top of each other.
- I would like to be able to change the order of the panels
- Here's the killer: I'd like to change the transparancy of the top panel (either partially or completely) so that I can peer through to the panel below.
Any advice would be appreciated. Many thanks...To summarise (thanks J_Rooze for advice):
- Setting the AlphaComposite value before calling super.paintComponent(g2) will change the transparency of the whole panel.
- Performance will drop in the order of ~40%, but using J_Rooze's suggestion to force the OpenGL rendering pipeline (above) completely remedies this (is there a similar hack for java3D?? :-).
- Using these panels with JLayeredPane worked completely for my spec (top post).
- I also tried them in CardLayout, however, whilst I could get the top panel to go transparent the underneath panel would not show through. This might not necessarily be a problem for other specs.
- Panels should be .setOpaque(false) to eliminate crazy phasing effects.
Here's my working code for reference:
import java.awt.*;
import javax.swing.JPanel;
public class DisplayPanel extends JPanel{
private boolean antiAlias;
private float alpha = 1.0f;
public DisplayPanel(boolean setAntiAlias) {
antiAlias = setAntiAlias;
this.setOpaque(false);
public void setAlpha(float a) {
alpha = a;
if (alpha > 1) alpha = 1.0f;
if (alpha < 0) alpha = 0.0f;
repaint();
public float getAlpha() {
return alpha;
protected void paintComponent(Graphics g) {
Graphics2D g2 = (Graphics2D)g;
AlphaComposite ac = AlphaComposite.getInstance(AlphaComposite.SRC_OVER, getAlpha());
g2.setComposite(ac);
super.paintComponent(g2);
// for speed
g2.setRenderingHint(RenderingHints.KEY_COLOR_RENDERING, RenderingHints.VALUE_COLOR_RENDER_SPEED);
g2.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_SPEED);
if (antiAlias) g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
//draw commands go here

JPanel Transparency Causes Artifacts
I am working on a battleship game an have a JPanel class which has a transparent color for a background (setBackground(new Color(1f, 1f, 1f, .25f));). When the panel is repainted, lots of artifacts appear and the background is one-half as transparent. Also, the current text is repainted on top of the previous text. I have searched the bug database and found that this is a common issue and can be worked around using setOpaque(false) and overriding paintComponent to paint the background. I did this, but there are still a significant amount of artifacts on the panel. Any ideas? Has anyone else seen this issue before? If so, how did you solve it?
Conditions:
J2SDK1.5.0 Beta1
Windows XP Pro (2 Different Machines)
Here's my paintComponent code:
public void paintComponent(Graphics g)
g.setColor(new Color(1f, 1f, 1f, .25f));
g.fillRect(0, 0, getWidth(), getHeight());
super.paintComponent(g);
}Thanks
Blake
[email protected]The artifacts are not caused by paintComponent. I posted it for reference to my second question. Maybe I should have seperated the questions for more clarity.
1. How do I work around the artifact issue?
2. I've read of a custom background painting workaround. Has anyone else heard of it? Did the paintComponent method body I posted in the initial post correctly address this issue?
To answer your question, I initialize no explicit Threads of any kind. I tried, but it made the artifacts worse.
Thanks.

Making JPanels transparent changes the look of the frame
Hi,
I wanted to set a background image on my internal frame, which contains more edits and buttons. This was easy, I set the image as background on the frame panel, then made all the JPanels containing elements transparent (=opaque(false)) so that the background is now visible.
Now my problem is that when there is no image to load (or no background wished) the former look of my frame became strage: there are 2 nouances of grey, the old gray from buttons is still there, but the containing panels are in a darker gray then the before. It seems to hang together with the new transparent panels. Setting a background color doesn't seem to help too...Do you have any idea, how could I restore the old "same gray overall" look?
Thanks for helping,
mariaYou may find the answer at the link shown below:
http://java.sun.com/products/jfc/tsc/articles/swing2d/index.html
Without seeing any code, I am guessing that the container's background is showing thru the first transparent component and the next's component's background is being added on top of it.

Hello!
I have a JFrame with a background painted on it and everything works fine so far, but when I create a JPanel in the JFrame the JPanels grey colour is laying on top of the background. So my question is how to make the JPanel transparent. I read about overriding the paintComponent method, but it didn't work, I'm probably doing something wrong.
This is what I did:
class Transparency extends JPanel {
public Transparency() {}
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
contentPanel = new JPanel();
contentPanel.setPreferredSize(new Dimension(mainFrame.getWidth(), 200));
contentPanel.setLayout(new BoxLayout(contentPanel, BoxLayout.Y_AXIS));
contentPanel.add(new Transparency());
mainPanel.add(contentPanel);I would really appreciate some help!Newly created JPanel's have their opacity set to true. This means "I guarantee that I will paint all the pixels within my bounds." For many components this amounts to simply filling in the entire bounds of the component with the background color as the first thing they paint. So by setting the opacity to false the JPanel in question will no longer be a gray blob and will allow any components beneath it to show through.
JPanel#setOpacity(false); The panel in question doesn't even need to be a custom subclass (read: delete that Transparency JPanel subclass). -

Given the FileTableDemo from the Java Foundation Class in a Nutshell book.(O'Reilly) Chapter 3 page 51 in my addition.
I have modified the example to place the JTable in a JTabbedPane. Now when the window (JFrame) is resized by the user the JTable no longer resizes. How do I passing the "resizing" into the component (JTable) placed in the JTabbedPane?
Here is the code: My deviation from the example is enclosed in "///////////KBS" and of course the line frame.getContentPane().add(myTP, "Center"); where "pane" has been replaced with "myTP"
Thanks Brad

else

// Create a TableModel object to represent the contents of the directory
FileTableModel model = new FileTableModel(dir);
// Create a JTable and tell it to display our model
JTable table = new JTable(model);

}Well, I didn't find an answer but I did find a solution.
The JPanel is the problem. I use it to help with layout which is not obvious in this example.
As you can see in the code the JTable is placed in a JScrollPane which is place in a JPanel which is placed in a JTabbedPane.
If I use Box instead of JPanel the JTable in the JScrollPane in the Box in the TabbedPane in the JFrame resizes correclty.
So although JPanel is resizable with setSize it does not get resized when it's JFrame gets resized.
I would still like to know why?
////////KBS
JTabbedPane myTP = new JTabbedPane();
Box myOne = Box.createHorizontalBox();
Box myTwo = Box.createHorizontalBox();
myOne.add(pane);
myTP.add("One", myOne);

In my project, I build a dialog box. I build a JTabbedPane within. Each tab is a panel with JChecxBox. When I add my first panel using the method addTab() no problem, with my second panel still no problem. When I try adding a third, an exception occurs: java.lang.ArrayIndexOutOfBoundsException: 2>1
I have also used the method printStackTrace to know what's going on:
java.lang.ArrayIndexOutOfBoundsException: 2 > 1

Hints: every tab in a JTabbedPane is a JPanel in fact. -
Hi,
I am having a JTabbedPane and using the following code to add Panels to JTabbedPane.
public class IntegratedUI extends JPanel{
public IntegratedUI() {
JTabbedPane tabbedPane = new JTabbedPane();
JPanel usagepanel = UsageConsole.makeFrame();
tabbedPane.addTab("UsageConsole",usagepanel);
tabbedPane.setSelectedIndex(0);
JPanel deploymentpanel =Generator.makedeploymentFrame();
tabbedPane.addTab("Deployment",deploymentpanel);
JPanel generatorpanel =WGenarator.makegeneratorFrame();
tabbedPane.addTab("Generator",generatorpanel);
setLayout(new GridLayout(1,1));
add(tabbedPane);
public static void main(String[] args) {
JFrame frame = new JFrame("XYZ");
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
frame.getContentPane().add(new IntegratedUI()
frame.setBounds(0,0,800,400);
frame.setVisible(true);
My JTabbedPane is displaying fine but my first Panel USageConsole is getting displayed.My second and third panel is not getting displayed.While i tried to debug using breakpoints.its calling the first class fine.The second and third class is not getting called.What could be the problem..
Thanks for your reply in advance.It looks like your Generator and WGenerator classes have static methods that are supposed to return JPanels, hopefully with components on them. I would write a small test app to verify that you can show these on their own; say, add each one to a JPanel with GridBagLayout, one panel per row. This way you can really see what's going on. I don't see any obvious problems in your tabbed pane code.

this.add(new JButton("Boton2"),java.awt.BorderLayout.EAST);
this.updateUI();
this.setVisible(true);
this.revalidate();
this.repaint();
} //Fin de la clase Applet16F84
When I use b extends Entorno1 and I insert as JPanel of JTabbedPane, not show it.
this.Tabbed1.addTab("Primera Pesta�a", b);
But this yes show it:
this.Tabbed1.addTab("Primera Pesta�a", a);
Why ? ..
Thanks !Your constructor is actually a method and not a constructor.
Therefore calling new Entorno1() returns you a blank panel.
change this
public void Entorno1(){
...to this.
public Entorno1(){that should do it..

How to switch between pages in a JTabbedPane
I hava form with a JTabbedPane whit 5 "pages" om page 1 there is a button that when pressed i want to switch to page 5 and display that content
I have tried the setSelectedIndex method but i does not work.. Any tips?How about the source code?
It must be buggy somewhere! There is no problem with those methods in my example.
Try this one:

Strangeness Using HTML with JTabbedPane
I'm getting some weird behavior when using html format for a JTabbedPane. It seems when I create tabs using HTML, it works fine, but when I subsequently try to change the tab title using JTabbedPane.setTitleAt(), the title doesn't change. The title doesn't change only when I create it with html. If I use "normal" text, the title changes fine.
I imagine JTabbedPane has a problem with html. I am using version 1.3 and compiling with JBuilder. Below is an example of my program. Uncomment mentioned lines to see it react strangely.
Any help would be appreciated.

Tab key event not fired in JTabbedPane
Hello,
I wanted to add the functionality of moving between tabs when Ctrl+Tab is pressed like Windows tabs.
But the tab key listener event is not getting fired by pressing Tab. For all the other key pushes it is working good. It this a problem with Java? Any workarounds?
Here is the sample code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TestTab extends JFrame
public void drawGUI()
//getContentPane().setLayout(new GridLayout(1, 1));
JTabbedPane lTabbedPane = new JTabbedPane();
JPanel lFirstPanel = new JPanel();
lFirstPanel.add(new JLabel("First Panel"));;
JPanel lSecondPanel = new JPanel();
lSecondPanel.add(new JLabel("Second Panel"));;
lTabbedPane.addTab("Tab1", null, lFirstPanel, "Does nothing");
lTabbedPane.addTab("Tab1", null,lSecondPanel, "Does nothing");
getContentPane().add(lTabbedPane);
lTabbedPane.addKeyListener(new KeyAdapter()
public void keyPressed(KeyEvent lKeyEvent)
System.out.println(lKeyEvent.getKeyText(lKeyEvent.getKeyCode()));
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
public static void main(String[] args)
TestTab lTestTab = new TestTab();
lTestTab.drawGUI();
lTestTab.setSize(200, 200);
lTestTab.setVisible(true);The KeyPressed events for TAB and CTRL-TAB are typically consumed by the KeyboardFocusManager for component traversal. What you have to do is adjust traversal keys and add CTRL-TAB as an action of your JTabbedPane. This is usually done with the InputMap/ActionMap, not a KeyListener:
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
public class X {
public static void main(String[] args) {
Set tabSet = Collections.singleton(KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0));
KeyStroke ctrlTab = KeyStroke.getKeyStroke(KeyEvent.VK_TAB, InputEvent.CTRL_DOWN_MASK);
final int FORWARD = KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS;
final JTabbedPane tp = new JTabbedPane();
//setFocusTraversalKeys to remove ctrl-tab as a forward gesture
tp.setFocusTraversalKeys(FORWARD, tabSet);
for (int i=0; i<6; ++i) {
JPanel p = new JPanel(new GridLayout(0,1));
JTextArea area = new JTextArea();
area.setFocusTraversalKeys(FORWARD, Collections.EMPTY_SET);
p.add(new JScrollPane(area));
area = new JTextArea();
area.setFocusTraversalKeys(FORWARD, Collections.EMPTY_SET);
p.add(new JScrollPane(area));
tp.addTab("tab " + i,p);
//add ctrlTab as an action to move to next tab
Action nextTab = new AbstractAction("nextTab") {
public void actionPerformed(ActionEvent evt) {
int idx = tp.getSelectedIndex();
if (idx != -1) {
idx = (idx + 1) % tp.getTabCount();
tp.requestFocusInWindow();
tp.setSelectedIndex(idx);
InputMap im = tp.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
im.put(ctrlTab, nextTab.getValue(Action.NAME));
tp.getActionMap().put(nextTab.getValue(Action.NAME), nextTab);
JFrame f= new JFrame("X");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.getContentPane().add(tp);
f.setSize(400,300);
f.setVisible(true);
