Could someone please tell me why in the following code the Scroll Pane does not appear? The code refers to two other classes I didn't include here although I've added comments to explain how they're used.
Thanks very much.
public class VPA extends JPanel implements ListSelectionListener {

subPanel.setLayout(new BoxLayout(subPanel,BoxLayout.Y_AXIS));
subPanel.add(Box.createRigidArea(new Dimension(0,5)));

listOfData = dataList.getList(); // listOfData is a JList
listOfData.addListSelectionListener(this);

to my code does not make any difference.

Hello all. I am trying to get a scroll pane to work in an application that I have built for school. I am trying to get an amortization table to scroll through for a mortgage calculator. It isn't recognizing my scrollpane and I am not sure why. Could someone give me a push in the right direction.

JScrollPane amortScroll = new JScrollPane(amortBox);The argument passed to a JScrollPane constructor specifies what's inside the scroll pane. Here, it seems like you're trying to create a scroll pane that displays a JLabel.
Also, I'm not sure what you're trying to do here:
amortScroll(showAmort);I don't see a method named "amortScroll".
You need to make a JTextArea, pass that into the JScrollPane's constructor, and add the JScrollPane to your frame. -
Setting scroll pane initial display size
hello.
how can i modify the modified code below so that users of my video library system would be able to view CD/DVD/Game information by name, age category, type and year? the text area is not displaying in a proper size - i have to use the scroll pane to view the data in the text area. i should be able to view the data in the text area without a scrollpane because there is not much data in the database. how can i make the text area bigger?
thanks.

Putting an image in a scroll pane
This is probably a simple question for most of you, but I need a little bit of help. How do I put a picture in a scroll pane?
The problem I have is that I can load an image and display it, that works fine. However, let's say I am making a new frame (I generally use JFrames), and I want to have a scroll pane in it. Let's also say I have numerous buttons around the edges (using a BorderLayout, or something). How do I load an image, draw the image on-screen and have it so that it only shows up in the scroll pane without the scrollbars disappearing?
I try to do it now, but for some reason the scroll bars of the scroll pane never show up. I can make the entire image be displayed by dragging the window edges bigger (the normal way you make windows bigger), and then I can see the entire picture. Unfortunately, the scroll bars on the scroll pane never show up if the window is too small to display the entire image. This is very puzzling, because I really don't know what I'm doing wrong. I have tried putting a panel in the scroll pane, and drawing on the panel, but still no scroll bars show up on the scroll pane if it is not big enough to show the entire picture / panel.
I am sure that the solution is very simple, but right now that solution eludes me.There's an example in the swing tutorials that seems to me to do exactly what you want.
See if http://java.sun.com/docs/books/tutorial/uiswing/components/scrollpane.html does the job, (less the border layout and buttons of course, but that shouldn't be too hard once you get the scroll bars working).
I believe the default scrollbar policy will let the scroll bars appear only when needed based on the bounds and the preferred size.
I used the example to set up a scrolling map (still just a gif image) and it works fine. If you still have trouble, you probably need to post the relevant section of code. -
New to Applets: Problems wiht writing to files and with scroll panes.
Hi, I've recently graduated from university and so I have limited experience in java programming and I'm having some trouble with JApplets (this is the first time I've made one). I'm trying to make a simple program that will allow users to pick one of a few background images from a list (a list of jpanels within a scroll pane) then at the click of a button will output a CSS with the background tag set to the image location. This is for use on a microsoft sharepoint site where each user has a My-Sit area which I want to be customizable.
So far I've been creating this program as an application rather than a JApplet and just having another class that extends the JApplet Class which then displays the JFrame from the GUI Class. This initially didnt work because I was trying to add a window to a container so I kept programming it as an application until I got it working before trying to convert it to a JApplet. I solved the previous problem by changing my GUI class to extend JPanel instead of JFrame and it now displays correctly but with a coupe of issues.
Firstly the applet will not create/write to the CSS file. I read that applets couldnt read/write to the users file system but they could to their own. The file I wish to write to is kept on the same machine as the applet so I'm not sure why this isn't working.
Secondly the scroll panel is no longer working properly. This worked fine when I was still running the program as an application when the GUI still extended JFrame instead of JPanel (incidentally the program no longer runs as an application in this state) but now the scroll bar does not appear. This is a problem since I want the applet to remain the same size on the page even if I decide to add more backgrounds to the list. I tried setting the applet height/width to smaller values in the html file to see if the scroll bar would appear if the area was smaller than the GUI should be, but this just meant the bottom off the applet was cut off.
Could anyone offer any suggestion as to why these thigns arnt working and how to fix them? If necessary I can post my source code here. Thanks in advance.Ok, well my program is made up of 4 classes, I hope this isnt too much to be posting. If any explaination is needed then I'll post that next. Theres lots of print lines scattered aroudn due to me trying to fix this and theres some stuff commented out from when the program used to be an application isntead of an applet.

Hi!
Im a newbie to swing so hopefully theres a simple solution to this.
Im beginning with a JScrollPane that has no data in it and is presented as such. However, when the relevant data has been selected i want to populate the scrollpane with the extracted data.
I ve started off with an empty JList that i ve instantiated in the constructor and placed in the JScrollPane. When the relevant button is pressed the list is updated with the new data, but im not sure how i can get also update scrollpane with the new list, with the results shown on screen.
Any help or code on how to do this would be much appreciated. Thanks in advance for any help.
ZidaneFor this situation Frist u take a JScrollPane
and take a JList in the JScrollPane when the
element is added in the list it will atomaticaly
give the effect
this code help for list and Scroll Pane

Remove/Hide scroll bars in scroll panes.
Hi all,
I am pretty new to action script. I am building a photo gallery and I am loading the thumbnails from an XML file into a scroll pane dynamically. As the scroll pane fills up, it gets wider to accomodate the thumbnails. There is one row, and eventually, I want to have the user be able to mouse left or right and have the scroll pane scroll, versus clicking on the bar or the left/right arrows. However, in order to accomplish this, I need the scroll bars to disappear!
Is there anyway to either remove or hide both the x and y scroll bars on a scroll pane? My scroll pane is called: thumbPane.
Thanks in advance!
-RobHello friend,
first select scrollpane.Then open parameters panel (if dont know go to window > properties > paramiters ) turn to OFF HorizontalScrollPolicy and verticalScrollPoliy then left and right scroll Bar will not display.
THANKS. -
IS IT POSSIBLE TO ADD A SCROLL PANE TO A PANEL??
Hi, Im trying to add a scroll pane to a panel but when I compile the code and try to open the form - a 'Illegal Argument Exception' is produced. Can anyone tell me whether it is possible to add a scroll pane the actual panel itself and also the code to do this.
Many Thanks, Karl.
I have added some sample code I have created -
public RequestForm(RequestList inC)throws SQLException{
inRequestList = inC;
displayForm();
displayFields();
displayButtons();
getContentPane().add(panel);
setVisible(true);
public void displayForm() throws SQLException{
setTitle("Request Form");
setSize(600,740);
// Center the frame
Dimension dim = getToolkit().getScreenSize();
setLocation(dim.width/2-getWidth()/2, dim.height/2-getHeight()/2);
getContentPane().setLayout(new BorderLayout());
Border etched = BorderFactory.createEtchedBorder();
panel = new JPanel();
panel.setLayout( null );
//panel.setBackground(new Color(1,90,50));
Border paneltitled = BorderFactory.createTitledBorder(etched,"");
panel.setBorder(paneltitled);
scrollPane1 = new JScrollPane(panel);
scrollPane1.setBounds(0, 0, 600, 740);
panel.add(scrollPane1);
}Hi all,
I am still having trouble here. would it be posible to add a scrollpanel to this form? Can anyone provide me with a working piece of code so I see how it actually works.
Any help would be greatly appreciated.

Dynamic content in scroll pane component
As far as I can see, the contentPath for a scroll pane
component can only point to a movie clip in the library, not to an
instance on stage. Does this mean that the content can only be
something created during authoring with no possibility of modifying
it in Actionscript?No, I had no reply and eventually wrote my own scroll pane
solution which allows me to directly modify the pane's content with
ActionScript and update the scroll bar to reflect any change in the
content's size. I'm puzzled by the help file's example in
ScrollPane.refreshPane() because it describes a senario where:
"for example, you've loaded a form into a scroll pane and an
input property (for example, a text field) has been changed by
ActionScript. In this case, you would call refreshPane() to reload
the same form with the new values for the input properties."
Which implies that you can use ActionScript to change the
content then reload it. The help file on ScrollPane.contentPath is
not very clear about what content can be used but appears to say
that the only content types allowed are: a SWF or JPEG loaded via
its URL or a symbol in the current library. I don't see how you
could use ActionScript to change any of these. I've tried
specifying an on-stage instance as the content but that
fails. -
Specifying text font in a scroll pane
Below is a fragment of code that attempts to display text in a scroll pane. Basically this works OK, except for the following:
1. Changing the font doesn't seem to make any difference. I tried "Arial", as shown, and "Curier", the display looks identical in both cases.
2. Multiple blank spaces are replaced by a single blank space. So that "Baa baa" is displayed as "Baa baa".
I would like to be able to display messages with many lines of text in a scroll pane preserving the format if possible, which relies on the blank spaces. I hope you can suggest how to do this better.
Thans for you help.

Scroll bar does not retain its position after or before pack
Hi
My Scroll bar does not retain its position after pack in my application.
But i need to retain its state.
My code snippet is :
System.out.println("VAlue--->" + getHXValue());
scrollPane.getHorizontalScrollBar().setValue(getHXValue());
pack();
My VAlue printed is 100.
But my positon of scroll bar is at 0 th location.
Can any one help me.....Swing related questions should be posted in the Swing forum.
My code snippet is :Snippets don't help.
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.
Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting. -
ImageIO image renders slow in scroll pane
Hello all, I need some help understanding the behavior of BufferedImage(s)
retrieved from ImageIO.read(). The problem I am having is weird .. I load
a PNG image via ImageIO.read(), I use it to construct an ImageIcon which
is later used in a JLabel/JScrollPane for rendering. When I attempt
to scroll the image in the scroll pane, it is very chunky and slow.
If I load the same image with ImageIcon(byte[]), there is no problem. The
image on disk is 186k, when loaded from ImageIcon(), it consumes about
10M, when loaded with ImageIO about 5M is consumed ... when I scroll,
the memory usage increase about 9 MB, which can be collected immediatly
to return to 5M.
Is ImageIO doing some fancy optimization to preserve memory, if so ... how
can I alter the settings or turn it off completly. I tried setting
ImageIO.setUseCache(false); that did nothing as far as I can tell.
The code to load the image is as follows, I am just using the default right now.
// perform base64 decoding from buffer
ByteArrayInputStream bos = new ByteArrayInputStream(decoded);
try
image = ImageIO.read(bos);
catch (IOException ioe)
}Any help would be greatly appreciated!!!
Cheers,
JodyI'm not sure if this is exactly what you are looking for but, here's code that works well for me:
private class MyJLabel extends JLabel {
public void paintComponent(Graphics g) {
super.paintComponent(g);
Graphics2D g2d = (Graphics2D)g;
URL imageLocation = MyJPanel.class.getResource("myImage.jpg");
Image myImage = Toolkit.getDefaultToolkit().getImage (imageLocation);
MediaTracker tracker = new MediaTracker (this);
tracker.addImage(myImage, 0);
try { tracker.waitForID(0); } catch (InterruptedException exception) { System.out.println("Image myImage.jpg wasn't loaded!"); }
g2d.drawImage(myImage, 0, 0, getWidth(), getHeight, this);
}Once I reload images using the above method, image repainting is very quick. Extend the JLabel (MyJLabel) to overwrite the paint method as above. Should work fast when you do so. You can move the image retrieving code out of the paint method and into the 'MyJLabel' constructor.
How are you painting the icon and where are you retrieving the image? Can you post more code?

Devyn
