JFrame look and feel

Hi everybody,
I'm a beginner in working with Java Look and Feel. I want to customize a frame's title bar, border and buttons. For example I want to put some other icons for the close, minimize and maximize button, change the height and color of the titlebar, and put some other border to the window.
My question is if I can do this by modifying the LAF. Maybe somebody can give me a link to some good and detailed documentation regarding LAF.
Thanks.

Hi,
You have a better chance to get your question answered if you post this in the Swing forum. (Do also mention that it is a cross-post, and provide a link to this thread)

Problem about look and feeling

i want to make my jframe looking and feeling like jdeveloper.what should i do ?

Hi,
if I remember well then JDeveloper uses the JGoodies Plastic Look and Feel. Just go to http://www.jgoodies.com/ and get the look and feel.

You are calling changeButtonColor(frame.getComponents()) before you add the JScrollPane to the content pane.
But why not just move this to the button creation loop?
button = new JButton("button" + num);
button.setBackground(Color.LIGHT_GRAY);
button.setBorder(BorderFactory.createLineBorder(Color.LIGHT_GRAY));

Windows look and feel instead, in InternalFrameDemo.java

Hi all, I am learning swing and I am trying to modify the
InternalFrameDemo.java source from
http://docs.oracle.com/javase/tutorial/uiswing/examples/components/index.html#InternalFrameDemo
My idea is to add the line
JFrame.setDefaultLookAndFeelDecorated(true); in the constructor, but it doesn't work
and I don't understand why.
Could somebody please help me?
Kindest regards,
Lasse
public InternalFrameDemo() {
super("InternalFrameDemo");
//Make the big window be indented 50 pixels from each edge
//of the screen.
int inset = 50;
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
setBounds(inset, inset,
screenSize.width - inset*2,
screenSize.height - inset*2);
//FDoesn't work
JFrame.setDefaultLookAndFeelDecorated(true);
//Set up the GUI.
desktop = new JDesktopPane(); //a specialized layered pane
createFrame(); //create first "window"
setContentPane(desktop);
setJMenuBar(createMenuBar());
//Make dragging a little faster but perhaps uglier.
desktop.setDragMode(JDesktopPane.OUTLINE_DRAG_MODE);
}

Uh I think you're mistaken. Whenever in doubt or something doesn't work as expected, check the javadocs. The link to the javadocs can usually be found really easily by typing "java 6 classname". In this case:
http://docs.oracle.com/javase/6/docs/api/javax/swing/JFrame.html
If you want to set the Windows look & feel as your thread title suggests, this was not the method you were looking for as the javadocs will tell you. That method controls if a frame is decorated or not (as the name suggests), which it is by default. Setting it to true will not change anything.
So what then? You type into Google "java swing windows look and feel". Without quotes of course.

Below is the executable code generated using NetBeans which is enough to generate the error message. Sometimes you can get the error message just by running the program. Sometimes the error will occur when you go into the Menu and click on Item.

Problem With ButtonUI in an Auxiliary Look and Feel

This is my first post to one of these forums, so I hope everything works correctly.
I have been trying to get an axiliary look and feel installed to do some minor tweaking to the default UI. In particular, I need it to work with Windows and/or Metal as the default UI. For the most part I let the installed default look and feel handle things with my code making some colors lighter, darker, etc. I also play with focus issues by adding FocusListeners to some components. I expect my code to work reasonably well no matter what the default look and feel is. It works well with Motif, Metal, and Windows, the only default look and feels I've tested with. What I'm going to post is a stripped down version of what I have been working on. This example makes gross changes to the JButton background and foreground colors in order to illustrate what I've encountered.
I have three source code files. The first, Problem.java, creates a JFrame and adds five buttons to it. One button installs MyAuxLookAndFeel as an auxiliary look and feel using MyAuxButtonUI for the look and feel of JButtons. The next button removes that look and feel. The next button does nothing except print a line to System.out. The next button installs MyAuxLookAndFeel as an auxiliary look and feel using MyModButtonUI for the look and feel of JButtons. The last button removes that look and feel.
The problem is, when I install the first auxiliary look and feel, buttons are no longer tabable. Also, they cannot be invoked by pressing the space button when they're in focus. When I remove the first auxiliary look and feel everything reverts to behaving normally. When I add the "Mod" version, button tabability is fine. The only difference is I've added the following code:
if ( c.isFocusable() ) {
   c.setFocusable(true);
}That strikes me as an odd piece of code to profoundly change the program behavior. Anyway, after adding and removing the "Mod" look and feel, the tababilty is forever fixed. That is, if I subsequently re-install the first look and feel, tababilty works just fine.
The problem with using the space bar to select a focused button is more problematic. My class is not supposed to mess with the default look and feel which may or may not use the space bar to press the button with focus. When the commented code in MyModButtonUI is uncommented, things behave correctly. Even the statement
button.getInputMap().remove( spaceKeyStroke );doesn't mess things up after the auxiliary look and feel is removed. So far I've tested this with JRE 1.4.2_06 under Windows 2000, JRE 1.4.2_10 under Windows XP, and JRE 1.5.0_06 under Windows XP and the behavior is the same.
All of this leads me to two questions.
1. Is my approach fundamentally flawed? I've extended TextUI and ScrollBarUI with no problems. This is the only problem I've encountered with ButtonUI. My real workaround for the space bar issue is better than the one I've supplied in the example, but it certainly is not guaranteed to work for any arbitrary default look and feel.
2. Assuming I have no fundamental problems with my approach, it's possible I've found a real bug. I searched the bug database and couldn't find anything like this. Of course, this is the first time I've tried seasrching the database for a bug so my I'm doing it badly. Has this already been reported as a bug? Is there any reason I shouldn't report it?
What follows is the source code for my example. It's in three files because the two ButtonUI classes must be public in order to work. Thanks for insight you can provide.

here is the code used to change the current look and feel :
try {

         catch (InstantiationException e)
              System.out.println("Error occured "+ e.toString());
         catch (ClassNotFoundException e)
              System.out.println("Error occured "+ e.toString());
         catch (UnsupportedLookAndFeelException e)
              System.out.println("Error occured "+ e.toString());
         catch (IllegalAccessException e)
              System.out.println("Error occured in .. " + e.toString());
         Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
         Fenetre fen = new Fenetre();
         fen.setSize(dim.width, dim.height);
         fen.setResizable(false);
             fen.setLocation(0, 0);
              fen.setVisible(true);

Transparent TextField with Synth Look and Feel

I am trying to use synth to implement a textfield with a transparent background, and having some problems with it. I can see my panel and the transparent field fine enough in the beginning, but when the text in the field changes, it writes right over the previous text and becomes a pile of unreadable white marks. I've experimented with varying degrees of transparency, but you can still see the old field underneath slightly. Does anyone have any suggestions? My code is below.
Thanks.
synth.xml
<synth>

<style id="panelStyle">
    <state>
        <imagePainter method="panelBackground" path="../../../lafImages/papyrus_bkgd.gif" sourceInsets="10 15 10 15"/>
    </state>
</style>
<bind style="panelStyle" type="name" key="PAPYRUS_PANEL"/>

<style id="textFieldStyle">
    <font name="Kudasai" size="12"/>
    <state>
        <color type="TEXT_FOREGROUND" value="#FFFFFF"/>
        
        <color type="BACKGROUND" value="#00000000"/>
    </state>
    <opaque value="false"/>
</style>
<bind style="textFieldStyle" type="region" key="TEXTFIELD"/>
</synth>
my tester
class SynthTester {
    private JTextField field;
    public SynthTester(){
        initLookAndFeel();
        JFrame main = new JFrame();
        JPanel panel = new JPanel();
        panel.setName("PAPYRUS_PANEL");
        field = new JTextField(3);
        field.setText("0");
        panel.add(field);
        JButton button = new JButton("+");
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                int val;
                try {
                    val = Integer.parseInt(field.getText());
                } catch( Exception ex ) {
                    val = 0;
                val++;
                field.setText(Integer.toString(val));
        panel.add(button);
        main.add(panel);
        main.pack();
        main.setVisible(true);
    private void initLookAndFeel() {
        SynthLookAndFeel lookAndFeel = new SynthLookAndFeel();
        try {
            InputStream is = getClass().getResourceAsStream("synth.xml");
            if( is == null) {
                System.err.println("unable to load resource stream");
            } else {
                lookAndFeel.load(is, getClass());
                UIManager.setLookAndFeel(lookAndFeel);
        } catch (Exception e) {
            System.err.println("Couldn't get specified look and feel ("+ lookAndFeel+ "), for some reason.");
            System.err.println("Using the default look and feel.");
            e.printStackTrace();
            System.exit(1);
}

As its name implies, an imagePainter element creates a SynthPainter that paints from an image. For example:
<synth>
<style id="example">
<state>
<color value="white" type="BACKGROUND"/>
</state>
<imagePainter method="panelBackground" path="background.png"
sourceInsets="5 6 6 7" paintCenter="false"/>
<insets top="5" bottom="6" right="7" left="6"/>
</style>
<bind style="example" type="region" key="Panel"/>
</synth>

HELP !! XP look and feel ...

how can i make my frame have an XP look and feel ??????
please help me in details , cause i haven't done this look and feel thing before ??? thanks in advance ..

You need to change to the windows LnF which is not the default. The
following code will do it for you. Note that it will only work if your
using Windows XP.
* LookAndFeel.java
public class LookAndFeel {
    public static final String MAC_CLASS = "com.sun.java.swing.plaf.mac.MacLookAndFeel";
    public static final String METAL_CLASS = "javax.swing.plaf.metal.MetalLookAndFeel";
    public static final String MOTIF_CLASS = "com.sun.java.swing.plaf.motif.MotifLookAndFeel";
    public static final String WINDOWS_CLASS = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel";
    public static final String GTK_CLASS = "com.sun.java.swing.plaf.gtk.GTKLookAndFeel";
    public static final String KUNSTSTOFF_CLASS = "com.incors.plaf.kunststoff.KunststoffLookAndFeel";
    public static boolean updateLookAndFeel(String currentLookAndFeel, java.awt.Component parent) {
     try {
         javax.swing.UIManager.setLookAndFeel(currentLookAndFeel);
            if(parent != null) {
                javax.swing.SwingUtilities.updateComponentTreeUI(parent);
     } catch(Exception ex) {
         System.out.println(ex);
            return false;
        return true;
}To get it to work do the following:
    LookAndFeel.updateLookAndFeel(LookAndFeel.WINDOWS_CLASS, this);where this represents your JWindow or JFrame.
Hope it helps.

Setting the Brushed Metal look and feel for macs using Java.

Hello,
I am relatively new to Java and I am new to Mac-specific java stuff. Anyways, when I try to set the look and feel of my classes to the "apple.awt.brushMetalLook" look and feel, I am unable to. It works if I have System.setProperty("apple.awt.brushMetalLook", "true"); written before I create any swing component. This would be fine, except that means that it is impossible to extend any swing component, such as JFrame or JApplet. Is there a way around this?
Thanks!

This might answer your question:

How to customize the title bar on my own Look And Feel?

Hi all!
I am creating my own Look and Feel which extends from NimbusLookAndFeel. What I'm doing is overwriting UIDefaults values??, referring to the Painters. For example:
+uiDefault.put ("Button [Enabled]", new ButtonEnabledPainter());+
But now I need is to customize the title bar of the JFrame's, but I do not see this option in Painter's values ??can be overwritten by Nimbus (http://docs.oracle.com/javase/tutorial/uiswing/lookandfeel/_nimbusDefaults . html).
You know as possible? I have to overwrite an existing UI component? The idea is I want to make the look and feel like SeaGlass, but the code seems a bit complex to know where to begin.
I hope you can guide me on this issue.
Thank you very much for everything! And excuse my English!.
Greetings!

JComboBox Lost Listener on Look and Feel change

When the user change the Look And Feel on the Fly , any Listener that is done using
myComboBox.getEditor().getEditorComponent().addXXXListener
is lost
I'm using Windows XP Service Pack 2, java 6 build 105
Does someone have any inputs why this happen or how this can be "fixed" or maybe prevent. Do I'm doing something wrong?

Drawing window borders swing look and feel

Does anyone know how to change the frame window border from being drawn in the windows look and feel? I want them to be drawn as a swing application. Can anyone help?

Frames (and JFrames) are top-level containers that are not subject to rendering by the Look-and-Feel manager (they are actually "heavy-weight" native components). However, in 1.4 it is possible to use an undecorated frame (using Frame.setUndecorated(true)) which you could paint to look like a JInternalFrame. However, I think you lose the automatic handling of resizing, moving, iconifying, maximizing, closing, etc.

Can combine two look and feel into new one?

Hi,
I want to change the JProgressBarUI of NimbusLAF on other LAF. I means how to put two different components each with different look and feel in single JFrame.Any way to get this. Help. Thankz.
Edited by: user13383557 on Nov 22, 2010 12:07 AM

How about reading the api doc and then message the appropriate method on the diverging component instance?
It's not recommended, though, and wont survive dynamic LAF changes.
