Swing components properties

Hi there!
I'm writing a gui generator from xml file. Consider this example:
<JFrame>
<height>100</height>
<width>50</width>
</JFrame>My problem is to link string from file (for instance "height") with a swing component property. I just want to avoid huge case block (case "height": setHeight() bla bla)

Good afternoon...
try this (i may have written myself, it may come from somewhere else, can't remember and there's no comments).import javax.swing.*;
import java.util.*;
public class ShowUIManager {
    public static void main(String[] args) {
        UIDefaults defaults = UIManager.getDefaults();
        System.out.println("Count Item = " + defaults.size());
        String[ ] colName = {"Key", "Value"};
        String[ ][ ] rowData = new String[ defaults.size() ][ 2 ];
        int i = 0;
        for(Enumeration e = defaults.keys(); e.hasMoreElements(); i++){
            Object key = e.nextElement();
            rowData[ i ] [ 0 ] = key.toString();
            rowData[ i ] [ 1 ] = ""+defaults.get(key);
            System.out.println(rowData[ i ][ 0 ]+"\t"+rowData[ i ][ 1 ]);
        JFrame f = new JFrame("UIDefaults Key-Value sheet");
        JTable t = new JTable(rowData, colName);
        f.setContentPane(new JScrollPane(t));
        //f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.pack();
        f.setVisible(true);
}

  • Enlarge JFrame and its components properties  proportionally

    Hi,
    We have a simple JFrame � Container - uses Flow Layout and has got Buttons, Text Fields� All of them are using Java�s default fonts, sizes..�
    And we want to increase or enlarge all of the JFrame and its sub components properties proportionally (especially Font�.) like in for example MS-Word.
    In the Ms-Word, there is ZOOM option in the Standard tool bar menu. If you set zoom to 150%, the font is automatically increases. And if you set it to 100% the font sets back to normal. And if the window is not enough to fit, it adds the scroll bars.
    For example, if we increase the Labels Font, the height of that component also should increase proportionally. So the Frame also should increase.
    How could we achieve this sort of functionality ( i.e. Proportionally increasing the component�s properties ) in Swing?
    I believe it is hard to set/adjust the all of the Frame�s components properties (I.e. Height, Font�) proportionally by using the Component listeners.
    (Another example, you might have noticed that the Frame�s Font, hight,width �sizes are proportionally bigger in Systems screen�s 800 by 600 pixels mode compare with 1024 by 768 pixels mode. May be this is windows feature. But we are looking at achieving the same sort of feature)
    Any help or thoughts would be appreciated.
    Thanks in advance.

  • Unicode font for swing components

    Hi all,
    I'd like to set a Swing component (a JLabel) to a particular font so it will properly display Unicode Greek text. I've been reading all about physical vs. logical fonts, and I've read through the various Sun docs/faqs on Internationalization, Fonts, and Unicode, but I just can't get this to work. I think I'm missing something more basic here about selecting my font. My test word is the Greek "khairete," with an accent over the iota. Here is the Unicode:
    \u03c7\u03b1\u1f77\u03c1\u03b5\u03c4\u03b5
    The trick is that accented iota.
    I can launch an xterm that shows the characters I want like this:
    $ xterm -fn -misc-fixed-medium-r-normal--18-120-100-100-c-90-iso10646-1 &
    That tells me that if I can get Java to use that font, then I'm all set. I'm trying the following test program:
    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
    import javax.swing.event.*;
    import java.io.*;

    container = getContentPane();
    container.setLayout(new GridLayout(0, 1));
    // try with the default font
    label = new JLabel(MESSAGE);
    container.add(label);
    printFont(label.getFont());
    // see what the default font looks like when PLAIN (to compare with fonts below)
    label = new JLabel(MESSAGE);
    label.setFont(label.getFont().deriveFont(Font.PLAIN, 12));
    container.add(label);
    printFont(label.getFont());
    // this looks the same as the default font, meaning we didn't find what we asked for.
    label = new JLabel(MESSAGE);
    label.setFont(new Font("-misc-fixed-medium-r-normal--18-120-100-100-c-90-iso10646-1", Font.PLAIN, 12));
    container.add(label);
    printFont(label.getFont());
    // this also falls back to the default.
    label = new JLabel(MESSAGE);

    Hi Sojan,
    first up, forget the notion of even tinkering with the font.properties file if you can. It's an old, outdated method of setting up the fonts that Sun doesn't even support any more. Use setFont() where you can, and die trying in the process! ;-)
    One thing I would check is which font each AWT component currently thinks it has. It's easy enough to set the font system wide with Swing components, but I'm not sure if that capability extends to AWT components (I've certainly had trouble with it in various places in the past). While you've set up the Chinese font correctly, your AWT components might still be stuck with the Java default (Helvetica, or whatever it is, which is incapable of displaying Chinese), and hence displaying the rectangles because they don't know how to handle the foreign characters. You might need to set SimSun as the font for each of your AWT components individually at a worst-case scenario.
    Hope that helps,
    Martin Hughes

  • Formatting swing for properties file

    this relates a bit to the last post I put on here about JTextAreas.
    I have a lot of properties files that contain strings used throughout the program.
    I was wondering what the ideal way of going about the formatting of the swing components the strings are used inside in relation to the properties file.
    The problem is that the lengths of the strings vary so much (and are used the same way), that its not a "one size fits all" screen.
    The properties only has the most required of \n's in it (This is the standard, correct?), so you have to setTextWrap(true) for the JTextArea. The problem with this is you do not have a way of dedecting the height.
    We are trying to get all of the message boxes formatted the same with the same length between the end of the text and buttons at the bottom, but cannot come up with a good way of doing this. character counting with FontMetrics does not work well since there are a few \n's in it. Adding \n to the properties file doesn't seem like an accurate solution. So basically, I have two questions:
    1)Does anyone have a way of dedecting the height of this jTextArea with textwrap on?
    2)What is the standard for interaction and spacing between a properties file and swing component?

    Could you post a small example, compilable and runnable, code that can reproduce your
    problem? I reread your first post and recognized that I didn't have understood your problem
    fully and in detail.
    trying to get all of the message boxes formatted the same with the same length between
    the end of the text and buttons at the bottomThis sentence is quite hard to swallow without real code or screen shot.
    Why multiple text areas?
    Buttons? What buttons?
    etc., etc. Questions are endless.

  • Persisting Swing Components

    Hello,
    I am having problems with the XmlEncoder. I have created a GUI using and MVC pattern and I am trying to Serialize my view and model in a xml format so i can reload it at a later time. However, The XmlEncorder is not writing out my CustomTables (A class that extends JTable with a DefaultConstructor and bean properties), nor is it writing out the JList swing Components. Due to the fact that it writes out my TextFields, ComboBox, and Checkboxes. I have tried to recreate my tables using the Data from my Model. However, it is not writing out List<Object> types. I have followed the Java bean convention, all my fields have "getters & setters". All of my Classes extends Serializable. Is there anything I'm missing? Those the encoder persist inner class?

    Hi,
    Thanks for the reply. I guess I was trying to take the other approach because the XmlEncoder tool is suppose to be able to persist swing components. However, I have also try to serialize the model with this tool and it is not Writing out all of my properties. I have used XStream to write the model out to xml and it works fine; so yes I can reinitialize my GUI with that. However, I am farely interested in the reason this XmlEncoder is not working. I have satisfied all of the requirements that has been define for this tool to work.

  • JCheckBox * Swing components

    I need help for JcheckBox Swing components.
    I am trying to set the state of JCheckBox each time even if i close the applicationn am=nd i open it again.
    i tries
    JCheckBox.setSelected(state);
    but it is not storing it when i open the application again.it lost the state .
    Thanks.

    Hi
    another (quite simple) solution could be the use of a class called Properties (have a look at this class in the Java doc), it can be used to store ini-files (textfiles in the format for example checkbox1=0 checkbox2=1 checkbox3=0 and so on (0/1 = false/true) ).

    Thanks for the response. I don't quite understand what you're talking about though. I have, in my humble knowledge, done nothing with packages. I have put the applet class (WiaRekenToolActiz.class is the applet class) in the jar file wia_actiz_archive.jar. From what I read on the tutorial, java looks for the applet class in all the jar files specified. Since I put my CODEBASE as the main url, I thought it baiscally didn't matter where you out the html file.
    I shall include the complete html page complete with applet tag to perhaps illuminate a bit more what I mean...

  • I can't use swing components in my applets

    When I write an applet without any swing components, my browser never has any trouble finding the classes it needs, whether they're classes I've written or classes that came with Java. However, when I try to use swing components it cannot find them, because it is looking in the wrong place:
    On my computer I have a directory called C:\Java, into which I installed my Java Development Kit (so Sun's classes are stored in the default location within that directory, wherever that is), and I store my classes in C:\Java\Files\[path depends on package]. My browser gives an error message along the lines of "Cannot find class JFrame at C:\Java\Files\javax\swing\JFrame.class"; it shouldn't be looking for this non-existent directory, it should find the swing components where it finds, for example, the Applet class and the Graphics class.
    Is there any way I can set the classpath on my browser? Are the swing components stored separately from other classes (I'm using the J2SE v1.3)?
    Thanks in advance.

    Without having complete information, it appears that you are running your applets using the browser's VM. Further, I assume you are using either IE or Netscape Navigator pre-v6. In that case, your browser only supports Java 1.1, and Swing was implemented in Java 1.2. You need to use the Java plug-in in order to use the Swing classes (see the Plug-in forum for more information), or else download the Swing classes from Sun and include them in your CLASSPATH.

  • Need help with using graphics in swing components

    Hi. I'm new to Java and trying to learn it while also developing an application for class this semester. I've been following online tutorials for about 2 months now, though, and so I'm not sure my question counts as a "new to Java" question any more as the code is quite long.
    Here is the basic problem. I started coding the application as a basic awt Applet (starting at "Hello World") and about a month in realized that Swing components offer better buttons, panels, layouts, etc. So I converted the application, called BsfAp, to a new JApplet and started adding JPanels and JComponents with layout managers. My problem is, none of the buffered graphics run in any kind of JPanel, only the buttons do. I assume the buffered graphics are written straight to the JApplet top level container instead but I'm not entirely sure.
    So as to not inundate the forum with code, the JApplet runs online at:
    http://mason.gmu.edu/~dho2/files/sensor.html
    The source code is also online at:
    http://mason.gmu.edu/~dho2/files/BsfAp.java
    What I would like to do is this - take everything in the GUI left of the tabbed button pane and put it into a JScrollPane so that I can use a larger grid size with map display I can scroll around. The grid size I would like to use is more like 700x1000 pixels, but I only want to display about 400x400 pixels of it at a time in the JScrollPane. Then I could also move this JScrollPane around with layout manager. I think this is possible, but I don't know how to do it.
    I'm sure the code is not organized or optimized appropriately to those of you who use Java every day, but again I'm trying to learn it. ;-)
    Thanks for any help or insight you could provide in this.
    Matt

    Couple of recs:
    * Don't override paint and paint directly on the JApplet. Paint on a JPanel and override paintComponent.
    * The simplest way to display a graphic is to put an image into an ImageIcon and show this in a JLabel. This can then easily go inside of the JScrollPane.
    * You can also create a graphics JPanel that overrides the paintComponent, draw the image in that and show that inside of the JScrollPane.
    * don't call paint() directly. Call repaint if you want the graphic to repaint.
    Here's a trivial example quickly put together:
    import java.awt.Color;
    import java.awt.Dimension;
    import java.awt.FlowLayout;
    import java.awt.GradientPaint;
    import java.awt.Graphics;

    import java.lang.reflect.InvocationTargetException;
    import javax.swing.JApplet;
    import javax.swing.JPanel;
    import javax.swing.JScrollPane;
    import javax.swing.SwingUtilities;
    public class BsfCrap extends JApplet
        private JPanel mainPanel = new JPanel();
        private JScrollPane scrollPane;
        private JPanel graphicsPanel = new JPanel()
            @Override
            protected void paintComponent(Graphics g)
                super.paintComponent(g);
                Graphics2D g2d = (Graphics2D)g;
                RenderingHints rh = new RenderingHints(
                    RenderingHints.KEY_ANTIALIASING,
                    RenderingHints.VALUE_ANTIALIAS_ON);
                g2d.setRenderingHints(rh);
                Paint gPaint = new GradientPaint(0, 0, Color.blue,
                    40, 40, Color.magenta, true);
                g2d.setPaint(gPaint);
                g2d.fill(new Ellipse2D.Double(0, 0, 800, 800));
        public BsfCrap()
            mainPanel.setPreferredSize(new Dimension(400, 400));
            mainPanel.setLayout(new FlowLayout(FlowLayout.LEFT));
            graphicsPanel.setPreferredSize(new Dimension(800, 800));
            graphicsPanel.setBackground(Color.white);
            scrollPane = new JScrollPane(graphicsPanel);
            scrollPane.setPreferredSize(new Dimension(300, 300));
            mainPanel.add(scrollPane);
        public JPanel getMainPanel()
            return mainPanel;
        @Override
        public void init()
            try
                SwingUtilities.invokeAndWait(new Runnable()
                    public void run()
                        setSize(new Dimension(400, 400));
                        getContentPane().add(new BsfCrap().getMainPanel());
            catch (InterruptedException e)
                e.printStackTrace();
            catch (InvocationTargetException e)
                e.printStackTrace();
    }

  • I'd like to make a list of interactive Swing components....

    EDIT: I've been doing more research about Layout Managers and it appears that BoxLayout may provide me with the solution I need. I'll mess around with it for awhile and report back if I still need help. Thanks pals!+
    I would like to make a list of JPanels laid out in basically a column. One on top of the other. That's not so difficult, but I need to make it able able to add and remove panels in response to user-driven events (in other words, I can't just hard-code them all, and the panels are generated on the fly, so I don't even know how many I'll need to be displaying until I need to display them.
    Here's a simple mockup of the window I'm talking about.
    |      - o x |
    |____________|
    |            |
    |            |
    |   Panel1   |
    |   Panel2   |
    |   Panel3   |
    |   Panel4   |
    |____________|At first, I thought a JList would serve my purpose, but you can't add interactive Swing components to JLists (or JTables)... they'll render, but that's all. My panels will contain a button and a checkbox, so this is a no-go.
    I was also thinking I could just manage the placement with GridBagLayout and just keep indexes for the current y position, but if there's an easier way, I'd rather not go this route. It has me writing a lot of extra code and manipulating a lot of fields of GridBagConstraints, which opens me to less-understandable code and more error-prone code, on account of I'm great at making little mistakes when I'm setting craploads of constraints.
    Does anyone have any ideas? It'd be ideal if there was just some sort of container I could plop them in with add and remove methods (a la JTabbedPane or something).
    I'm pretty new to Swing, so maybe I'm missing something obvious.
    Edited by: Caryy on Sep 30, 2010 4:15 PM

    I would recommend using BoxLayout or Box.createVerticalBox(). As mKorbel already mentioned, you need to call revalidate() after adding any component to an already realized/visible container, and additionally call repaint() after removing a component. To resize the top level window to accommodate its new content, you would call pack(). Or, again as suggested by mKorbel, wrap your panel/Box in a JScrollPane.

  • Showing swing components in the palette og jdeveloper

    hello, I have found a problem with jdeveloper, as a user uses jdeveloper since 2 years I have never found a problem like this. (IDE problem).
    like habitude I created a simple java project which contains a jframe and an entry class (main class), but when I try to drag and drop from the component palette somes swing components I didn't find
    the page of swing components ( I found in the components palette just "my components" page in the jcombobox selection category). this problem will delay a big project and causes big problems
    please any person who know some things help me as soon as possible.

  • About the difference between the AWT components and the swing components

    As we know that an AWT component has a peer, but dose a lightweight component(e.g: a swing component) has also a peer? And could somebody tell me that who and how creates the CLICKED_EVENT when I click a JButton(a swing component), and where the CLICKED_EVENT to go util it was processed by a method like btn_ok_clicked(Event e)? And if I click a Button(an AWT component), what's the difference?
    Thanks a lot!

    The main difference is that AWT are native components, and Swing components are entirely in java written. That's besides the look and feel. There are a lot of other differences between AWT and Swing, and there are better described in the documentation.

  • Multifont output in Swing components

    Hi there,
    though I'm not new to Java but I'm new to displaying different fonts in Swing components.
    I have an Swing-based application which is running on a Terminal Server. It works fine for Central, Western und Northern Europe. The next
    country to roll out is Greece. So what does a greek user see on his monitor when he uses his greek keyboard?
    I am writing a test app where I type german text into a JTextField and want to get e.g. the greek representation in another JTextField. How can I achieve this? Converting the bytearray with Cp1253 did not work
    Can anybody give me a hint?
    Thanks
    Dierk.

    as I wrote, it is a test app to learn how I get greek
    fonts on the screen. Of course the real app is used by
    greek users who put greek text into the system. In the
    system we do not use resource bundles as the GUI texts
    are stored in the database. It is a CMS for product
    information in different languages.Ah, I see... mind you, I don't think your German text would have a great deal of Cyrillic characters in them, right? Still, it's only a test! ;-)
    Now what I'm doing to get my german text in greek
    letters is this:
    utf8Bytes =
    = getorigTextField().getText().getBytes("UTF16");
    isr = new InputStreamReader(new
    w ByteArrayInputStream
    (utf8Bytes), "Cp1253");
    As far as I understand, the InputStreamReader gives
    the translation
    of my german letters in the encoding of CP1253
    (Windows Greek). That
    means the unicode characters change into the ones of
    the greek language
    so I should be able to show them in a Swing component.This is where your problem is. Java's Strings will always be in UTF-16 when they are held internally. So anything within a textfield is going to be UTF-16 no matter what you do with it.
    The line you think is converting to Cp1253 is actually trying to convert from Cp1253 to UTF-16.
    Hopefully this is the reason your characters aren't appearing - the unneeded conversion above could be mashing them. Instead, you need expect everything to always be in UTF-16, and to expect to display in it (don't worry, it handles any character you can throw at it, let alone Greek). So then it all comes down to the font you're using.
    I'm not too sure of the name of the Windows default Cyrillic font, but that would be a logical starting point.
    Hope that helps!

  • Swing components not displaying correctly in JApplet

    Hello everyone,
    I have experienced some strange problems using Swing components on JApplets. Maybe I missed some documentation somewhere and someone can help me out.
    The problem is that when I add components like JButtons,
    JCheckboxes, JRadioButtons, JTextFields, JPasswordFields,
    and JComboBoxes to JApplets, when I view the applet, the
    component does not become visible until I move the mouse
    pointer over it in the case of buttons. For the JComboBox I have
    to hit the mouse key many times on the component to see the list. Has anyone experienced problems like these? Thanks.
