Thin JFrame Border, Metal look and feel

Hello,
For an assignment of mine I am required to write a GUI that has thinner Window border then usual. The Frame of the window needs to be about half the size that it currently is. I'm looking to find the best way to do this. Is there a way to use the UI manager, or do I need a complete overhaul of the top-level container? Boy, I hope not!
Thanks in advance!

Metal Look and Feel

I am trying to get the metal look and feel which was the default look and feel from 1.4. I used the following code.
try
UIManager.setLookAndFeel(new MetalLookAndFeel());
SwingUtilities.updateComponentTreeUI(this);
catch (Exception e) {System.out.println("Exception");}
but I am still getting the ocean look and feel.

Ocean is the new default theme for Metal. Use
MetalLookAndFeel.setCurrentTheme(new DefaultMetalTheme())

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!

Look And Feel: Metal Themes

Hello,
I have two basic questions I can't find the answer to. I hope someone can help.
From my understanding of Java 1.5 you now have 2 basic themes to them metal look and feel, they are "Ocean" (the default) and "Steel". Is this understanding correct?
My second question is, I can switch between Look & Feels, ie. default to system, how do you switch between themes though? I want to use "Steel" but can't !
Thanks,
Alan

How to Set the Lood and Feel:
http://java.sun.com/docs/books/tutorial/uiswing/misc/p
laf.htmlThat actually doesn't tell you how to do what he's asking.. at least not from what I saw.
Here's how to set the metal theme in 1.5:
import javax.swing.plaf.metal.*;
public static final String STEEL_THEME_CLASS = "javax.swing.plaf.metal.DefaultMetalTheme";
public static final String OCEAN_THEME_CLASS = "javax.swing.plaf.metal.OceanTheme";
public void changeMetalTheme(String themeName) {
   try {
      MetalTheme theme = (MetalTheme)Class.forName(themeName).newInstance();
      MetalLookAndFeel.setCurrentTheme(theme);
   catch (Exception e) { e.printStackTrace(); }
}Note that if you do this after you've created your GUI, you'll have to call SwingUtilities.updateComponentTreeUI() on all top-level windows.

Look and Feel

Salutations,
I am writing a simple swing program that when the user clicks a button corresponding to a look and feel name ie "Metal" etc. the Look and Feel is Changed, it works great except for one problem, it will not change to the "Metal" look and feel, I believe this to be the default look and feel, but when changed to another, it will not change back. Any suggestions?
thanks,
J

Here's the code from the SwingSet2 Demo:
// Possible Look & Feels
    private static final String mac      = "com.sun.java.swing.plaf.mac.MacLookAndFeel";
    private static final String metal    = "javax.swing.plaf.metal.MetalLookAndFeel";
    private static final String motif    = "com.sun.java.swing.plaf.motif.MotifLookAndFeel";
    private static final String windows = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel";
        try {
            UIManager.setLookAndFeel(currentLookAndFeel);
            SwingUtilities.updateComponentTreeUI(this);
            // where currentLookAndFeel is one of those Strings
        } catch (Exception ex) {
         System.out.println("Failed loading L&F: " + currentLookAndFeel);
         System.out.println(ex);
// And as an (unexpected) bonus, it's the same as the code I once used:
static String windowsClassName = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel";
        try
            javax.swing.UIManager.setLookAndFeel(windowsClassName);
            javax.swing.SwingUtilities.updateComponentTreeUI(this);
        catch(Exception e)

GUI Look and Feel

Hi,
I am developing GUI's with SWING and I am developing on a Windows XP machine and all my code no matter what I do looks like Windows frames. Is there a trick to get everything to look like "metal" look and feel? I tried numerous techniques that the java tutorials say will alter it but it never does... Is it somthing with XP?
Thanks,
Ben

After a bit of peliminary swing hacking...
overide javax.swing.plaf.metal.MetalTitlePane.SystemMenuBar.createActions() to return a subclass of the exisiting Maximise action that sets to corrected dimensions.
subclass createTitlePane in MetalRootPaneUI to return your new class
then set the metal UI to use your new new RootPaneUI and stand back and feel smug!
I don't need to do this, but this should work!
HOWEVER... exactly how you decode where on teh screen the taskbar starts/ends is anybody's guess.

Strange look and feel behavior

Hi!
I'm developing a little program using JDK 1.1.8. I'm using the Metal look and feel, and everything goes well. The componentes are showed perfectly. Because I need to distribute the program to other PCs, I have compressed the program into a Jar file. In the other PC I've installed the JRE 1.3 that has capability to double click on a jar file and run it. The problem is that when I run the program with the jar method, the size of the components changes (especially the tables, and the fonts), and I don�t understand why, because I have specified in the beginning of the program to use the Metal Look and feel.
What can be the problem?
Thanks a lot!

There've been an awful lot of bug fixes and changes between 1.1.8 and 1.3 -- I'm not surprised there'd be some differences.
I'd say install 1.3 on development machine and see how it looks -- probably looks different as well. If you want to know specifically why, then you're gonna have to read all the release notes for each update from 1.1.8 thru 1.3 and you'll probably find alot of reasons.

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));

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)

Look and Feel : Metal !

I'm working with "design" in JBuilder, all components are "Swing" but when
i run my program then it's not display in Metal model, it's display in Windows model.
How i do to my program display in Metal model? Please eveyone help me!

Hi! :)
That's because JBuilder uses the native look and feel each time. You can comment out the lines in the code JBuilder is producing that are responsible for the LAF.
If I may, a piece of advice... Forget JBuilder's designer! It's crap!

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 {
               UIManager.setLookAndFeel("com.sun.java.swing.plaf.motif.MotifLookAndFeel");
         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);

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.
