BorderLayout focusmovement
Hello
I've set up a BorderLayoutManager, but I have problems of application of the focus-movement.
I watched "Advanced managers Implement howto" in the resources of the developer, but I saw that it's even there that the application is not as I want.
I managed to implement the movement between the different cells of the BorderLayout, but when I add a Manager to one of the fields of the BorderLayout, I can't move the focus to that Manager.
For example, suppose that I have added a VerticalFieldManager to the center of the BorderLayout and a focusable LabelField to the South. If I move down, the focus goes immediately from the Manager in the Center to the labelfield in the South (instead of going into the second field in my verticalfieldmanager)
Can someone explain how I can do the above?
I'll post my code BorderLayoutManager as soon as I have this problem of fixed focus!
Thank you!
Thanks for the help!
Here is my code BorderLayoutManager. There are a few restrictions (East and West aren't focusable, 1 only one field per location), but the implementation is perfect for what I need to. Do not hesitate to extend the functionality!
PS: Utils.max calculates the max of 3 values.
Code:
Import net.rim.device.api.ui.Field;
Import net.rim.device.api.ui.Manager;

Confusing behavior of get with BorderLayout
Hello, I have a borderlayout with sort of a footer at the bottom which displays useful information on what is going, im just to add a step by step tutorial widgety thing there, its going to be a JScrollPanel with all different JLabels and an icon of a tick or cross etc etc.
My problem is with the get, when all signs in her 'fit' on the chassis, then the scrollpane PADD out height with enough space for a scroll bar (but there isn't one, so its shared out above and below the panels) However, when space is insufficient and the get show his bar along the bottom He does not eat in this 'extra' space, the space is removed, he eats in the panels (I think that he has in fact reduced space panels have in any case) that I find confusing, I expected little to eat in space Panel (as it normally does), but it actually reduces space more that she should and adds some unnecessarily when its not need!
its kind of hard to explain, but this example shows exactly my problem, it is a footer, I just want that it extend upward a bit when the scroll bar is displayed instead of ruin! :
Curiously, his only ever the right size just before he needs of the horizontal scroll barimport java.awt.*; import javax.swing.*; public class Test extends JFrame { public static void main(String[] args) { Test Test = new Test(); Test.setSize(new Dimension(600,500)); Test.setVisible(true); } public Test() { Container c = this.getContentPane(); c.add(new JLabel("resize me smaller"),BorderLayout.PAGE_START); JPanel myPanel = new JPanel(); myPanel.setBorder(BorderFactory.createLineBorder(Color.pink)); myPanel.add(new JLabel("A nice label, oh wait its too long! (actually its too short, hence why i am adding this)")); c.add(new JScrollPane(myPanel, JScrollPane.VERTICAL_SCROLLBAR_NEVER,JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED), BorderLayout.SOUTH); } }
I hope someone can help
JoeThe text of the label "resize me more small" must really say ++ 'resize the width of the frame smaller. "+" This will make the problem more obvious.
If you change the code to:
//Test7.setSize(new Dimension(600,500)); Test7.pack();Then the label is initially displayed at its default size.
I don't know why the height of the label continues to change as overtemperature/increase in the width of the frame. I'd wait the height remains the same.
The only solution I have is a brute force solution:
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Test7 extends JFrame { public static void main(String[] args) { Test7 Test7 = new Test7(); // Test7.setSize(new Dimension(600,500)); Test7.pack(); Test7.setVisible(true); } public Test7() { Container c = this.getContentPane(); c.add(new JLabel("resize me smaller"),BorderLayout.PAGE_START); JPanel myPanel = new JPanel(); // myPanel.setBorder(BorderFactory.createLineBorder(Color.pink)); JLabel label = new JLabel("A nice label, oh wait its too long! (actually its too short, hence why i am adding this)"); myPanel.add(label); JScrollPane scrollPane = new JScrollPane(myPanel, JScrollPane.VERTICAL_SCROLLBAR_NEVER,JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED); c.add(scrollPane, BorderLayout.SOUTH); JScrollBar sb = scrollPane.getHorizontalScrollBar(); sb.addComponentListener( new ComponentAdapter() { @Override public void componentShown(ComponentEvent e) { JScrollBar scrollBar = (JScrollBar)e.getComponent(); JScrollPane scrollPane = (JScrollPane)scrollBar.getParent(); JViewport viewport = scrollPane.getViewport(); Component c = viewport.getView(); Dimension d = scrollPane.getSize(); d.height = c.getPreferredSize().height + scrollBar.getPreferredSize().height; scrollPane.setPreferredSize( d ); scrollPane.revalidate(); scrollPane.repaint(); } @Override public void componentHidden(ComponentEvent e) { JScrollBar scrollBar = (JScrollBar)e.getComponent(); JScrollPane scrollPane = (JScrollPane)scrollBar.getParent(); JViewport viewport = scrollPane.getViewport(); Component c = viewport.getView(); Dimension d = scrollPane.getSize(); d.height = c.getPreferredSize().height; scrollPane.setPreferredSize( d ); scrollPane.revalidate(); scrollPane.repaint(); } }); } }The other option is to always display the horizontal scroll bar.

Hi all. I was wondering if you could help me to answer this question. I'm doing a JFrame using BorderLayout. In this JFrame, I try to add two JButtons in the North and South stations. Also, I try to add a JPanel that also uses the BorderLayout and place it in a central position of the JFrame. In the JPanel, I try to add the same as those of the two JButtons in the JFrame to the North and the South in the BorderLayout of the JPanel. I tried to explain that as best I could, but here's a concept further photo http://i1104.photobucket.com/albums/h324/wildbill1009/conceptart/jpanel.jpg. I'm certainly not achieve the expected results. So I guess the real question I need to answer is what I am doing wrong? Below the source code. Thank you.

So I guess the real question I need to answer is what I am doing wrong?A component can have only one parent. Adding a component to a container removes any container in which it was previously added.
If you need separate JButtons, with the same functionality, consider building with the same Action. An Action can be shared between several s element.

How to show VerticalFieldManager at the bottom of the screen?
Hello everyone
I have three VerticalFieldManager as TitleManager, MainManager
and BottomManager.
I want to organize these vertically by ensuring that the BottomManager will
always at the bottom of the screen and is only MainManager
Functionality of SCROLLING VERTICAL so that the entire screen will not get scrolls.
This is possible with the BorderLayout, which is not present in the Blackberry development environment
What could be the best possible solution for this task?
A lot of useful things, like this, explained here:

Overlap two images, ordinary java works, and not in BlackBerry JDE 5
I have an application for swing of simple java that takes two images and overlaps the other. While trying to this port in JDE5, I got out there is no class BufferedImage in the api of BB, but a similar class of the Bitmap. It's brought to BB mixing function is unable to produce an image that overlap. It shows a blank white screen.
Here's the plain java function

Hello
I need a screen that displays text at the top of the screen and text on the bottom of the screen.
Swing you can do with a BorderLayout, but y at - it an easy way to achieve this goal with the BB API?
Thank you
easy way would be to use setTitle and setStatus class screen, they offer built-in managers at the top and bottom of the screen. You can also use the absolute layout to position your fields or add a NullField with a given height (override getPreferredHeight)

Kifani - only two instances of bean - dispatchCustomEvent fails
11.1.2.1 forms
I have a bean with the implementation defined in CardReader.CardReaderWrapper class. When the form starts up you can see the init() method is called. This action creates an instance - see red Objct1. When I push the button and do the fbean.invoke method, it creates another instance, see red objct2, and the dispatchcustomevent() method fails. Looks like I should have only one instance of the kifani not two? It is a failure in the last line of code before the call to forms - dispatchCustomEvent (this); IM so close...

This page contains three applets. When I just a cmdlet, it seems to work without error.
Interestingly, when I go to the page with three applets, it will load occasionally. So it seems that if I load the page with three applets on it of in the applet in the page simple applet, three applets fails. If I load the page with three applets on it directly, it loads OK.
Thank you.
With the help of first class at Oracle, this problem was identified and resolved.
It was not a problem of Java, but the error to the user.
Our web application connects to Java Plug - in System Properties (i.e., System.getProperties ();) to a server log at sign to help diagnose problems with plugin java browser. The applet sign - we send them down to the server. Before sending them down, it was a copy of the system properties and then removing two of the properties: "line.separator" and "line.separator.applet". Why do we remove them? Simply to avoid an unwanted line break appear in the server log file.
Well, what was supposed to be a copy of the system properties was actually a reference to the system properties. Then when we removed these two properties, the CharacterEncoder has failed because it relies on the property system being present and pure "line.separator".
To make a long story short, we were pulling the rug under the JVM itself, rewriting of the vital system property values.
Our sign on the applet has done this for years. Somehow we got away with it until version 1.8.0_40 - b25.

Hi all
I developed a JavaFx 2.0 application. JavaFx 2.0 works fine and I get an impressive appearance for my GUI. The GUI is created with FXML and CSS files.
My application works in combination with the NASA WorldWind (which only works with swing). The two applications (jfx and worldwind) communicates via java Sockets because I found no way to do natively (I needed to swing inside jfx).
Both applications consume a Web services created in Visual Studio and running on IIS . The web service provided little data. The application isn't a web application use this solution to solve a problem.
The JFX application use timers (to access webservices data) every second and send and receive messages via the plug regularly.
Well, now my problem...
Sometimes my GUI created by JFX2.0 locks and this is not necessarily in a specific time, but rather the action.
I'll appreciate any help.
Javier V
p.d. sorry for my English
EDT is the short name for the "Event Dispatch Thread" which is the event thread and redraw used in Swing.
EDIT - I see, WorldWind uses JOGL. Currently, a direct insertion in a JavaFX UI of JOGL, using SwingNode content is not possible (easily). There are however some efforts of the community to allow JOGL and JavaFX working together (ie: https://github.com/AqD/JOGL-FX) so it is perhaps possible to change WorldWindowGLCanvas of WorldWind of the GLCanvas of JOGL original than that can be incorporated within JavaFX.
EDIT 2 - http://forum.worldwindcentral.com/showthread.php?36896-WorldWind-for-JavaFX , it is possible to integrate WorldWind directly in JavaFX using the component WorldWindGLJPanel instead of WorldWindowGLCanvas.
The following code works well:
public class Main extends Application { @Override public void start(Stage primaryStage) { final SwingNode swingNode = new SwingNode(); final StackPane root = new StackPane(); root.getChildren().add(swingNode); Scene scene = new Scene(root, 300, 250); primaryStage.setTitle("Test WorldWind"); primaryStage.setScene(scene); primaryStage.show(); SwingUtilities.invokeLater(() -> initializeWorldWind(swingNode)); } private void initializeWorldWind(final SwingNode swingNode) { // final WorldWindowGLCanvas wwd = new WorldWindowGLCanvas(); final WorldWindowGLJPanel wwd = new WorldWindowGLJPanel(); wwd.setPreferredSize(new java.awt.Dimension(300, 250)); final JPanel panel = new JPanel(); panel.add(wwd, java.awt.BorderLayout.CENTER); wwd.setModel(new BasicModel()); swingNode.setContent(panel); } /** * @param args the command line arguments */ public static void main(String[] args) { launch(args); } }This test works well for me.

Dear members. I need your help please
I have a game I'm hosting at www.hiredforoneday.com
I signed the code with Comodo M/s. I wrote the manifest file (and changed so many times) but I still get the Oracle security warning:
"This application will run with unrestricted access, which can put your computer and personal information at risk.
Run this application if you trust the place and the editor above.
I'm must admit am bat / do not understand what I do.
Please I need your help on how to write the code manifest, how correctly put it in the jar and how to reference the html code
The game can be played online from www.hiredforone Day
I need the system clock of the client and also I used getResources() to read images in the jar file
on the site, I have a (Play) button. During a call to the play button, the index page connects to the file play.html which is located in the folder pots.
The file play.html calls the HiredForOneDay.jar file that is located in the folder of the pots. Files such as launch.jnlp, launch.html are all in the jarsfolder.My game using Cardlayout (CardLayOutClass) in the Applets init() the
cardLayoutClass.showCongratulationsPanel (); which shows the Congraculations class
then setJMenuBar (helpTopicSelector.getBar ()); HelpTopicSelector is also another class
Here is the code
[code]
package hiredforoneday;
/**

cardLayoutClass.showCongratulationsPanel ();
setJMenuBar (helpTopicSelector.getBar ());}
} [/ code]I didn't send in the manifest code because I did so many versions and now am confused
Thanks again for your time

I don't think it's possible to prevent the warning message from appearing at least once. There could be an option 'do not show this again' on the dialog box warning that users can check to prevent it from appearing again. Codezone-the only thing I can think is to eliminate the dependency on the system clock client side so that the attribute in the manifest file permissions can be set to 'sandbox' rather than 'all rights '. You don't know if he read images from the same signed jar file still qualified under 'sandbox' - try it and see.
It is worth noting that other publishers Java RIA as the Knowledge Base for the Skillsoft Support are also facing the same issue, and they document simply as a relatively mild warning message.

Display JList holding JLabel with icons of different heights screwed up
I started to create a wrapper for unix 'make', that filter for binary files created and display their names and potentially an icon for those in a JList.
But sometimes the display of icons is screwed. It is cut to the size of a pure text (JLabel) line in the JList.
Below you can find the test program.
You have to put two image of different size of the files binary1.jpg and binary2.jpg in the execution of the generation of java directory (I use eclipse)
and create a test like this input file:
> cat input binary1 binary2 binary3 binary4 binary5 binary6 binary7 binary8 binary9
The build run directory TEST_DIR environment variable value.
Finally start the java class as follows:
> bash -c 'while read line; do echo $line; sleep 1; done' < input| (cd $TEST_DIR; java -classpath $TEST_DIR myTest.MyTest)
Then you should see the question.
(Doesn't bother me on the JAVA code in general - I know, that there is enough other questions of difficulty :-))
-Thanks a lot!
Best regards

Strange behavior on the web page of preloading in WebView
I have the following problem: in my Swing application, I want to display a web page. To do this, I use a JFXPanel that contains a WebView. The web page must be loaded in the background, and only if the loading process is totally finished I want to make the JFXPanel visible. I use the
getLoadWorker().workDoneProperty() method of the corresponding WebEngine to determine if the page is totally loaded.The problem is, now that the JFXPanel gets visible, I see initially a totally empty Board, and after a short period, the web page in Web view is visible. I made a simple Application demo that reproduces this behavior. If the page is loaded, a button is enabled and clicking on this button adds the WebView Panel below. In addition the link following points to an animated gif that shows the behavior: http://tinypic.com/view.php?pic=oh66bl & s = 5 #. Ujv2IhddWKl
Here is the code of the demo application:

To me, it seems that the WebView starts to render the site just to the point where it becomes visible. What can I do to get the WebView already shows the web page is loaded right now that it becomes Visible (to avoid this effect of flickr)?
I already posted this question on StackOverflow (see http://stackoverflow.com/questions/18873315/javafx-webview-loading-page-in-background ) but didn't get an answer and found this forum today.
Thanks in advance!
Try the updated version in this post.
It requires a snapshot offscreen before displaying the Web mode to make sure all is rendered before the Web is displayed.
The code is kind of ugly and the 'solution' is a bit of a hack, you would probably want to clean it up a bit before using it anywhere (for example, there is no need to create a new WebView and snapshot, web page on each load - I did it just to get a feel for the worst-case scenario and try to pinpoint where are produce slowdowns).
A small rectangle moves back on the top of the screen so that the fluidity of the animation can be monitored.
On the first charge, there will be a slight stutter in the animation, but the rendered web page instantly appears when click the show page"" button.
As you say, the stuttering occurs only the first time the page is loaded, then everything is smooth. If you use a progress bar regular instead of an animation, the initial stuttering is probably fine, because people expect to see breaks in the progress bars from time to time (more progress reported by progress bars is not a smooth linear progression). My guess is that if you use a regular progress bar, the behavior seen with this example is probably acceptable for almost all users.
As for the differences between the rendering between 2.2 JavaFX and JavaFX 8, there was a lot of changes to the internal architecture of JavaFX for JavaFX 8 that have improved rendering performance, as well as probably represents the delta.

Bug of concurrency in example of SimpleSwingBrowser.java?
Take a look at the demo of the Oracle of incorporation JavaFX in a Swing application:
http://docs.Oracle.com/JavaFX/2/swing/SimpleSwingBrowser.Java.htm
I wonder if this example is not due to lack of follow the obiter that all objects of Swing all should be created or modified only on the event Dispatching Thread (EDT). The correct way, canonical to reach this goal is:
SwingUtilities.invokeLater (new Runnable() {}
public void run() {}
createAndShowGUI();
}
});
However, the example of SimpleSwingBrowser.java of it this way:
Public Shared Sub main (String [] args) {}
SwingUtilities.invokeLater (new SimpleSwingBrowser());
}
SimpleSwingBrowser is an executable, but the problem is that the assessment of the 'new SimpleSwingBrowser()' expression occurs on the main thread, and among other things, it is the initialization of the Member fields that create objects of Swing. For example:
/ public class SimpleSwingBrowser implements Runnable {}
...
private JFrame frame = new JFrame();
private JPanel Panel = new JPanel (new BorderLayout());
Private JLabel lblStatus appearing = new JLabel();
I don't think it's kosher (although it will probably not create a problem). Am I wrong?
Thank you.

I don't write a lot of code Swing, so someone more with the framework would be best to confirm the problem.
That said, your analysis seems OK for me.
If you get all the other answers, you can connect to a bug report:
-
Well, im trying to learn how to use the JDesktopPane and I found some examples on the web, and I can't make it work "properly".
This example is just a menu with a menu of the element that adds an internal frame, the internal frame adds a Textfield itself and this is the part that I don't understand, for some reason, the TextField is not visible.
If I run debug, I see in a snapshot of MISTLETOE, the framework is actually created but I can't. Here's the code.

How to add the listener to use mouse to one single line
I have a requirement. In a JTable when I double click on a particular line the cells in the row put the width which I have provided.
The problem with my code is when I click on the fourth row of the table, the first line adjusts.
How I need help is so
that if I click on the first row, the first cell size line should be adjusted not when I click on the fourth line.
If I give a few cells of the width and the height of the cells in the fourth row, then when I double click on the fourth line, the fourth should only get adjusted and not the other lines.
Hope I explained it clearly.
How is it possible?
