How to make chart scrollable?

Hi everybody,
I want to ask how to make a chart become scrollable (just like a chart with a scroll bar that help us see all content in this chart when this content become to large).
Because my line chart adding series data based on real time, so the content change dynamically. And when the content change, I don't want the axis change its size to fit the chart size, because it make the line chart smaller and narrow.
I have seen in JavaFx Ensemble the example *"Advanced Stock Line Chart Sample"*, it seem like what I looking for. But this chart clear the old data after a period. I want chart to keep the old data and when I want to review, just scroll back
Can anyone give me suggestion?

Have you looked at ScrollPane.... http://docs.oracle.com/javafx/2/api/javafx/scene/control/ScrollPane.html
You can just throw your chart in there. Then if your chart gets bigger then the screens dimensions the ScrollPane will become scrollable.

How to make JFrame scrollable?

How can I make a JFrame scrollable? So that when I resize the JFrame to a smaller size the contents remain accessible? The way it is now is that when I resize a JFrame I can't access the components that fall out of the window (I'm using absolute component positioning within the JFrame). I thought adding two scrollbars to take care of this would be easy, but so far I haven't been able to get it right. Any suggestions would be appreciated.

Why dont you put all your components in a JPanel, add a scrollpane to it and then add that JPanel to
ur JFrame.

How to make a scrollable applet

How do I make an applet scroallable? Not a scrollpane within an applet but instead make the whole contentpane for the applet as a scrollable pane if the content within the applet�s contentpane is too small to view all the added content. Or if the applet is added to a frame to be run as an application and the frame size is decreased.
That is, how do I make a scrollpane that fills the whole contentpane for the applet and is resized together with the applet�s contentpane? What do I for example have to add to this little applet to make it�s contentpane scrollable?
public class Applet extends javax.swing.JApplet
    public void init()
        // Initialization of the applet pane
        getContentPane().setBackground(java.awt.Color.WHITE);
        getContentPane().setLayout(null);
        // Adds some content
        JLabel label = new JLabel("Applet application");
        label.setSize(100, 20);
        label.setLocation(10, 10);
        getContentPane().add(label);
}It is probably very easy but I can�t figure it out myself yet, I am still too new to Swing : )

Thank you for your answer, but I am not quite happy yet ...
What is it so bad with use of null-layout? I have found that I can use exact positioning using setLocation if I set use null-layout which I can�t with for example BorderLayout. It is even worse, the BorderLayout makes the UI ugly by size of the content to fill one out of five "cells". But I know I am wrong when I say nul-layout is fine because many other also complains on null-layout, I just don�t know why I am wrong?
But any way, with null-layout, something like this ...
       JPanel contentPane = new JPanel(new java.awt.BorderLayout());
       getContentPane().add(new JScrollPane(contentPane));
       JScrollPane scrollpane = new JScrollPane();
       scrollpane.getViewport().add(getContentPane());
       // Initialization of the applet pane
       contentPane.setBackground(java.awt.Color.WHITE);
       contentPane.setLayout(null);
       contentPane.add(table);do I just get a white empty area. If I instead use a BorderLayout like in your example do the table fill the whole space, and that does not look too beautiful. Couldn�t I instead get a pane with some absolute positioned elements that has some space around them scrollable?
I guess I am on the wrong direction now : ) but I then need someone to teach me why?

How to make a SCROLLABLE Table in ADF Faces ?

Hi All,
I want to make my ADF Table Scrollable (both Horizontally & vertically). It means when I have 30 rows on the table, I can make it only display 10 rows visible, then scroll it vertically.
Also If I have wide tables(many columns) I can scroll it horizontally.
Is it possible with ADF Faces ?
(I look at FrameBorderLayout, but it seems not be able to do that )
Thank you,
xtanto

Hi,
What about the Horizontal scrolling ?
for exampe :
I have about 15 columns, the full page width can only shows 10, so I need to scroll horizontally, But I don't want to scroll the page, only the table.
Is there any ADF Faces components for this ?
or any commercial JSF components ?
Thank you,
xtanto

How to make dos window scrollable under win98?

Hi, I am using win98, every time when I run my GUI application, whenever I got bunch of error message that can not be displayed in one window, I will miss the original error information. Can anyone tell me how to make my dos window scrollable so that I can view all error message.
Thanks a lot.

I don't think that you can do this. There is another way, however: When java throws an exception, if it is not caught in your program, it is sent to the standard error, which is the console. You can simply reset this to be a file, so you can read this to get all the error info. Try using the following code in your main method:
public static void main(String[] arg) {
    try {
      System.setErr(new PrintStream(new FileOutputStream(new File("Errors"))));
      //instantiate your main class here
      MyClass mc=new MyClass(); //or whatever
    } catch (Exception _ex) {
      System.out.println("An error occurred"); //exception get sent to standard error automatically, so there
                              //is no real need to catch this exception. However, I use it to display
                              //a message on the console to let me know an error has occurred.
      System.err.println(_ex.getMessage()); //and finally, print the exception to file
      _ex.printStackTrace();
}

How to activate JMenu from other frame using accelerator key

Hi.
I'm developing an application for my final year project.
i set up my application to have multiple frame open at the same time (like sunone studio in SDI mode). only one JFrame contains the JMenuBar.
i can activate this menu bar using the accelerator key when the containing JFrame has focus. however, i donot know how to make the Menu activate when the accelerator key is pressed on other frame. press help, thanks in advance.

does any one have some idea.
the solution i found seem not suit my need.
i want to be able to pull down (and get the focus transfered to) the jmenu in menubar of another frame using the menu's mnemonics. using InputMap does not seem to fit since i need to the menmonic of menu is not in the input map.

JDialog Problem: How to make a simple "About" dialog box?

Hi, anyone can try me out the problem, how to make a simple "About" dialog box? I try to click on the MenuBar item, then request it display a JDialog, how? Following is my example code, what wrong code inside?
** Main.java**
============================
publc class Main extends JFrame{
public Main() {
          super();
          setJMenuBar();
          initialize();
public void setJMenuBar()
     JMenuBar menubar = new JMenuBar();
        setJMenuBar(menubar);
        JMenu menu1 = new JMenu("File");
        JMenuItem item = new JMenuItem("About");
        item.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent ae) {
              // About about = new About(this);
           // about.show();
        menu1.add(item);
     menubar.add(menu1);
public static void main(String args[]){
     Main main = new Main();
}** About.java**
=============================
import java.awt.*;
import javax.swing.*;
public class About extends JDialog{
     JPanel jp_top, jp_center, jp_bottom;
     public About(JFrame owner){
          super(owner);
          setDefaultCloseOperation( DISPOSE_ON_CLOSE );
          Image img = Toolkit.getDefaultToolkit().getImage(DateChooser.class.getResource("Duke.gif"));
          setIconImage( img );
          setSize(500,800);
          Container contentPane = getContentPane();
         contentPane.setLayout(new BorderLayout());
         contentPane.add(getTop(), BorderLayout.NORTH);
          contentPane.add(getCenter(), BorderLayout.CENTER);
          contentPane.add(getBottom(), BorderLayout.SOUTH);
          setResizable(false);
           pack();
           setVisible(true);
     public JPanel getTop(){
          jp_top = new JPanel();
          return jp_top;
     public JPanel getCenter(){
          jp_center = new JPanel();
          return jp_center;
     public JPanel getBottom(){
          jp_bottom = new JPanel();
          jp_bottom.setLayout(new BoxLayout(jp_bottom, BoxLayout.X_AXIS));
          JButton jb = new JButton("OK");
          jp_bottom.add(jb);
          return jp_bottom;
}

Code looks reasonable except
a) the code in the actionPerformed is commment out
b) the owner of the dialog should be the frame
If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)",
see http://homepage1.nifty.com/algafield/sscce.html,
that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.

How to make view automatically scroll when keyboard show up

Hi all
I'm like a totally noob for objective-c coding, let alone the iPhone programing. :P
Anyway, I somehow manage to create a simple application that receive input via UITextField, do some simple math, then display the result in other UITextFields (which can act as a input vice versa).
Problem is, when I use the UITextField at the buttom of the screen as an input, the keyboard will block that text field out of my view, so I could not see what I'm typing at all.
That's the question. How to make my view scrollable, and make it simply scroll itself out of the way when the keyboard is shown? I already inherit my view from UIScrollView, but don't know what to do next. Can you guys help enlighten me, please?
Thanx

Of course, if you're dealing with textFields, you should change a few things try something like that in your .m file :
- (void)textFieldDidBeginEditing:(UITextField *)theTextField
if ([theTextField isEqual:yourTextField])
// Restore the position of the main view if it was animated to make room for the keyboard.
if (self.view.frame.origin.y >= 0)
[self setViewMovedUp:YES];
// Animate the entire view up or down, to prevent the keyboard from covering the author field.
- (void)setViewMovedUp:(BOOL)movedUp
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
// Make changes to the view's frame inside the animation block. They will be animated instead
// of taking place immediately.
CGRect rect = self.view.frame;
if (movedUp)
// If moving up, not only decrease the origin but increase the height so the view
// covers the entire screen behind the keyboard.
rect.origin.y -= kOFFSETFORKEYBOARD;
rect.size.height += kOFFSETFORKEYBOARD;
else
// If moving down, not only increase the origin but decrease the height.
rect.origin.y += kOFFSETFORKEYBOARD;
rect.size.height -= kOFFSETFORKEYBOARD;
self.view.frame = rect;
[UIView commitAnimations];
- (void)keyboardWillShow:(NSNotification *)notif
// The keyboard will be shown. If the user is editing the author, adjust the display so that the
// author field will not be covered by the keyboard.
if ([yourTextField isFirstResponder] && self.view.frame.origin.y >= 0)
[self setViewMovedUp:YES];
else if (![yourTextField isFirstResponder] && self.view.frame.origin.y < 0)
[self setViewMovedUp:NO];
#pragma mark - UIViewController delegate methods
- (void)viewWillAppear:(BOOL)animated
// watch the keyboard so we can adjust the user interface if necessary.
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification object:self.view.window];
- (void)viewWillDisappear:(BOOL)animated
[self setEditing:NO animated:YES];
// unregister for keyboard notifications while not visible.
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
be sure to invoke the method when you dismiss the keyboard, so that the view "falls back" to its normal state:
if (self.view.frame.origin.y < 0)
[self setViewMovedUp:NO];
Of course, declare the method
(void)setViewMovedUp:(BOOL)movedUp;
in the .h file
and the #define you will use in you .m file :
// the amount of vertical shift upwards keep the text field in view as the keyboard appears
#define kOFFSETFORKEYBOARD 50.0
// the duration of the animation for the view shift
#define kVerticalOffsetAnimationDuration 0.30
good luck !

Make animation scrollable without large stage?

Hi,
I've seen many videos showing how to make an animation scrollable but so far, they all involve using a large stage in the composition. I'm looking for ways to export the animation into a Wordpress page, so I'd like to avoid having a huge dive inside the page that's already built.

Hi Vivekuma,
Thanks for the code, but does it work on stage that's the same size of the animation (300px wide x 400px tall)? Imagine a a bracelet composed of two pngs. I'm trying to make them open/close as the user scrolls up or down through the page.
At first, I was able to accomplish that by placing the two pngs in a stage with a large height (2000px) a parallax code and a library from http://cdn.edgecommons.org/. All this, in Edge Animate.
Thing is, I'd like the stage to be 400px tall, export the animation as a package and insert it at the bottom of a Wp page so the animation reacts to the scroll bar that the page already has.
So far, I've tried using the html output and nest it into another div, but that seems to "break" the animation. I also used a plugin called Edge Suite, which easily uploads the animate package but it doesn't react to scrolling.
