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 : 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!

F2 Edit in JTable -- standard for all look and feel ?

hi,
I use a robot to simulate a F2 when a column is in focus in a JTABLE so that user can just type without having to type the <F2> key.
My question is:
Is F2 (to get a column in edit mode) for JTABLE standard for all look and feel (metal, X-windows ..) ?
Thanks.
Tony

Read the JTable API. There is a link the gives the
standard key assignments for the standard LAF's.thanks. got it.

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())

BSP - Look and Feel / Theme

Good Morning All,
disclaimer: I checked the blogs, I checked the discussions, I checked the examples, I checked the doco - and couldn't find the answer to my question.
Question:
I've already seen it, but can't remember where it is, does anyone know the name of the BSP Sample/Example which comes with the WAS which has the EP6 look and feel ?
I saw it a few weeks ago and I can't find it now and I want to study the code from it to make my app have a nicer look and feel.
Note: I read Thomas's blog on - 'A developer's Journal Part VI
and although that example discussed what I am interested in I couldn't see examples in the code of creating the header bar etc, maybe it's just me, but at the moment that's what I would like to achieve and to do it by example.
So to conclude if anyone knows / can remember the name of the BSP example which has an EP6 look and feel please let me know so that I can study it for inspiration.
Thanks very much,
Milan.

Hallo Milan,
I think that you are doing good. It is always the best to follow a small mix of documentation reading and practical work. So let me tell you the minimum to get a first version working. Thereafter to can continue reading!
Problem: we want to implement a simple link tag (in 15 minutes!) that works like this:
<%@page language="abap"%>
<%@extension name="htmlb" prefix="htmlb"%>
<%@extension name="bcm06" prefix="bcm06"%>
<htmlb:content design="design2003">
<htmlb:page>
 <bcm06:simpleLink href="http://www.sap.com">
 SAP Home Page!
 </bcm06:simpleLink>
</htmlb:page>
</htmlb:content>
In SE80 we defined a new BSP library bcm06. We define a new element simpleLink. Typical handler class name will be CL_BCM06_SIMPLELINK (just the convention we use). As body this tag can contain other HTML and also over BSP elements (we want to just render a link around all of body). We don't worry about the rest of the checkboxes. They will become interesting later on.
We activate the library. The workbench will detect that no handler class exists, and will generate all of the stuff we need. Now already the tag is full functional, and can be used on any BSP page. It just will not do anything.
What was generated? The class inheritance diagram is as follow: CL_BCM06_SIMPLELINK --> CLG_BCM06_SIMPLELINK --> CL_BSP_ELEMENT.
The class CL_BSP_ELEMENT is the base class, and it contains a lot of interesting functionality. None of which we worry about now. Never try to change it!
The class CLG_BCM06_SIMPLELINK (note that CLG_!) is generated new each and everytime that you touch the definition of the tag. Effectively all the defined attributes are generated onto this class, so that they are already of the correct type, and that this information is always in sync. This means that all your tag defined attributes are directly attributes on your class. In our case, the defined "href" attribute (type string) is now an attribute on the CLG class.
The last class CL_BCM06_SIMPLELINK will only be generated once if it does not exist. This is the class where you work. In this class there are two methods that are interesting to you at this moment. Later you will learn about the rest.
DO_AT_BEGINNING: This method is called effectively in response to the <lib:tag> sequence. This is the code that executes before the body. This is the place where we would like to render out "<a href=...>" sequence.
DO_AT_END: This method is called effectively at the end of the tag, when the </lib:tag> is seen. The body has now already been processed and sent onto the output stream. So we only need to render "</a>".
Note that these methods are implemented empty. You *MUST* overwrite them, and implement them in your class. See instructions from Thomas. Source code:
METHOD if_bsp_element~do_at_beginning.
DATA: html TYPE string.
CONCATENATE `<a href="` me->href `">` INTO html.
me->print_string( html ).
rc = co_element_continue.
ENDMETHOD.
METHOD if_bsp_element~do_at_end.
me->print_string( `</a>` ).
rc = co_page_continue.
ENDMETHOD.
Notice that you DO NOT need that super call. The base method will always be empty (from definition, will never change). You also have a direct PRINT_STRING method in newer SPs. The return code you must set. (To tell the truth, the constants for RC have been picked so perfectly that if you forget them, it should not hurt in 85% of the cases.)
That is it. Test page. Mine worked!
Of course, we can start looking at more exotic things, like empty tags, at tags that skip their bodies if not required, processing the body, validation, etc.
But this overview was just to give you that first success feeling, and also to give you a better framework for understanding more of the documentation as you continue to read.
Recommended: read <a href="/people/brian.mckellar/blog/2004/06/11/bsp-trouble-shooting-getting-help">Getting Help</a> to see how you can quickly navigate between BSP page and a tag's definition, from where you also quickly get to the implementation class of the tag.
bye, brian
PS: Now if this is not already the first page of your weblog done

SAP Portal Custom Themes to change ESS/MSS UI Look and feel , possible ?

Hi,
I have a requirement where the look and feel of the UI controls of the ESS/MSS applications have to be different - Jazzy
I know XSS homepage framework is for the customisation of Areas, Sub Areas. What I am more interested is only the look and feel UI of ESS/MSS applications.
If I change the standard theme of portal using Theme Editor and create a new custom theme with different back ground colors, fonts, sizes for all the UI controls,.Will the customised Theme apply on the standard ESS / MSS screens ? Also my doubt is we are using EHP3 and I am not sure how many are Webdynpro java based or webdynpro Abap based.
Will the theme apply to both WDA and WDJ application UI controls?
Any inputs in this regard will be of great help. thanks in advance.
Regards,
Sreeram

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!

Thank you in advance.
Swapna

Hi Swapna,
Portalapp.xml is the configuration file of portal application holding comonents and services. Where as authschemes.xml file is used to determin and tell portal which of the user authentication schemes is to be used. It also tells portal about which logon PAR file should be used. It is defined inside following tags.
<frontendtarget>Logon PAR File Name</frontendtarget>.
Take a scenario for example. You have created a custom logon PAR file and made some changes. You cannot see the changes before deploying it. You have to deploy it first. Now, you want that whenever somone logon to portal, your logon PAR should be referred and executed. Authschemes.xml does this work. It maintains a reference to the PAR file that should be used for logon.
Now, still have to create a custom authschemes.xml file and upload it. (Follow this link for the authschemes file location http://help.sap.com/saphelp_nw04/helpdata/en/1a/3afd4e641b8f42ac07bb77fe30375b/content.htm)
Refer this link for details on authschemes.xml file: http://help.sap.com/saphelp_nw04/helpdata/en/d3/1dd4516c518645a59e5cff2628a5c1/content.htm
Let us see in brief what are the steps executed:
1) You request a portal login
2) Portal, after receiving a request, looks for a reference to which Authschemes file to be used. It finds it in Visual Admin
3) Once portal have the name of authschemes file, it parse this file and determin what are the authentication schemes to be used and which logon PAR should be executed.
4) Only after these steps, it renders logon page to you
Once you do all these steps, you can see the result on logon page itself. You do not have to look for deployed PAR file.

JFileChooser & XP look and feel

Hello!
I'm changing an exiting applet to have a local look & feel by simply doing this:
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); When the JFileChooser shows with the "metal" (java default) Look&Feel all is good but when it shows with
XP (or windows) L&F it has added a "panel" on the left side with icons for "My Recent Document" , "Desktop" , "My Documents", "My Computer" and " My Network places".
I really don't want them showing since it looks weird on the HTML page.
Does somebody know if and how I can get rid of that "panel" and still have the rest of the L&F intact?
Regards Calle

Check out skin look and feel. They have all sorts of look and feels including windows XP.

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);

Notification center look and feel

The new notification center look and feel seems quite unlike the rest of the iPhone.
Most of the iPhone has a light colored, rounded, kind of comfortable look. But the new notification center has a much more dark, angular look. (To me, it looks more like an Android app than an iOS component.)
Any chance it can be rebranded? Or failing that, any chance of a settings option to customise the background image, so I can at least change from the dark "linen" texture to a wallpaper of my choice? (e.g. it might look much nicer (to me!) if I could change it to use the default iPhone water drops background). The slide down button itself (the bit of the notification center graphics which appears on screen, even in full-screen mode, if you make the 'wrong' move) could be much more rounded, as well.

iOs 5 in general looks and feels awkward to me. It feels cheap and not at all as polished as Apple's products have been in the past. The alarms have new colors for no apparent reason, the text messages have colors for no apparent reason, the notification center has a distracting texture, again, for no reason... Yet none of these colors or textures are configurable or removable. What was the point exactly?
This theme shift is quite discouraging in the grand scheme of things. It doesn't bother me much, but I definitely prefered the way my phone looked when I bought it.
