JTextArea is not scrolling!
Hi :
I have a JTextArea inside a scrollpane, when I manually type the character it will scroll if it doesn't fit . However, if I use append("some text\n") in my program, the JTextArea was vertically enlarged rather than scroll up and down.
Any suggestion?
thanks

You can use textArea.setMinimumSize()/setPreferredSize()/setMaximumSize() to force the JTextArea to remain a fixed size.
The other option is to change your Layout manager to something that uses a fixed size for a component based on the size of the container - e.g. BorderLayour (center) or GridLayout.

Hi everyone,
I have looked at many of teh posts in this forum and have yet to find an answer that seems to work for me. My problem if that i have a JTextArea that is in a JScrollPane, but as things are added to the JTextArea via the append() method, it does not scroll once tthe viewable window if full. here is some of teh code which builds the panel which contains it :
private void buildChatPanel(){
chatPanel=new JPanel();
JTextField outbox = new JTextField(20);
JButton sendButton = new JButton("Send");
inbox = new JTextArea();
chatPanel.setLayout(new GridBagLayout());
//chatPanel.setBackground(Color.BLACK);
GridBagConstraints gbc = new GridBagConstraints();
// Build the text input field
setBackground(new java.awt.Color(51, 51, 51));
outbox.setText("Enter Chat");
gbc.gridx = 0;
gbc.gridy = 0;
gbc.gridwidth = 3;
gbc.ipadx = 14;
gbc.insets = new Insets(3, 3, 3, 3);
chatPanel.add(outbox, gbc);
//build the send button
sendButton.setToolTipText("Click to send chat message");
sendButton.setMargin(new java.awt.Insets(0, 0, 0, 0));
sendButton.setPreferredSize(new Dimension(75, 25));
sendButton.setRolloverEnabled(true);
gbc = new java.awt.GridBagConstraints();
gbc.gridx = 2;
gbc.gridy = 2;
gbc.insets = new Insets(3, 3, 3, 3);
chatPanel.add(sendButton, gbc);
//build the text area
inbox.setEditable(false);
inbox.setPreferredSize(new Dimension(200, 20));
inbox.setLineWrap(true);
inbox.setWrapStyleWord(true);
gbc = new java.awt.GridBagConstraints();
gbc.gridx = 0;
gbc.gridy = 4;
gbc.gridwidth = 3;
gbc.ipadx = -20;
gbc.ipady = 493;
gbc.insets = new Insets(3, 3, 3, 3);
JScrollPane jsp = new JScrollPane(inbox,
ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS,
ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
chatPanel.add(jsp, gbc);
}I tried to used inbox.setCaretPosition(inbox.getText().getLength()) right after any call to the append() method, but that did nto seem to work either. Any Ideas at all would be great!
THANK YOU ALL!!I don't know if you ever figure out what was causing this. But I came across the same problem. The IDE that I was using had auto generated the following two lines in my source code:
jTextArea1.setMinimumSize(new Dimension(70, 70));
jTextArea1.setPreferredSize(new Dimension(70, 70));
I commented out both of these and the jTextArea began to scroll both vertically and horizontally.
Good Luck, -
hello forum,
my JList (indentifier=PKGList) does not scroll. Can any look at code and tell me what's the problem. Following is the code. To test this code create two files in same directory. No package statement is there in code.
1. javaEditor.java
2. key_words.java
copy the respective codes. compile these files.
run command >> java javaEditor .
Then my GUI will appear. click "new file" from file menu.
then type "import". press SPACE BAR. a list box will appear conatining list of some packages.
This is where the problem is [b]. this list box does not sroll.
at some places,for the ease of identification, i have put the comments..
///PAY ATTENTION HERE BEGINS
and
///PAY ATTENTION HERE ENDS .
I will be thankfull whoever helps me.

JTextArea/ScollPane - Unwanted Scrolling
Hello,
I am trying to insert text and have the "scroller" move down
if , and only if , the "scroller" is already down as far as it can go. When I insert,
when im not scrolled to the bottom , I get "NO" printed , as expected. However
after appending the text the scrollbar then scrolls to the bottom of the document.
Can I stop this behaviour?
Thank You,

Mail does not scroll while in full screen!
When on full screen mail just ignores the fact that there's more stuff (text, pics...) in the email and does not scroll down. No bar on the side, no scrolling with arrows, touchpad or space bar is working. When I bring it back to a smaller size or just open the email in a sparate screen it works OK.
Not a huge issue, but an irritating one, wonder if this is happening to anyone else? and if anyone has a good fix to it?
Thanksthe release notes say it has issues in non-interactive mode,
I'm using doing :
stage.displayState =
StageDisplayState.FULL_SCREEN_INTERACTIVE;
Is there maybe something else I need to set to full screen
interactive? I know I saw somewhere that the person was setting the
htmlLoader's stage to full screen interactive. I tried that but it
did nothing.
I have the window style set to "system chrome". I tried
transparent and no flash sites worked(full or normal screen) and
opaque worked the same as system chrome. -
anyone help please my phone woint stop telling me everything sice pressing a button for voice on a translator app. the screen will not scroll. I have sync the phone deleted the app on the lap top but it wont let me delete it on the screen because its frozen. I have taken out the sim card.. I have turned it off now Im stuck.. Im in a small village in Spain and cannot get to an Appke store to get it fixed yet. Any ideas?
Plug your phone into the wall charger for at least 30 minutes...make sure you have a sim card in the phone...then:
Leave the USB cable connected to your computer, but NOT your phone, iTunes running, press & hold the home button while connecting the USB cable to your dock connector, continue holding the home button until you see “Connect to iTunes” on the screen. You may now release the home button. iTunes should now display that it has detected your phone in recovery mode, if not quit and reopen iTunes. If you still don’t see the recovery message repeat these steps again. iTunes will give you the option to restore from a backup or set up as new.
Make sure you have no anti-virus software running or any firewalls...turn all of that stuff off. -
I can not scroll on my dell studio touchpad and I am running Windows 7 and Firefox 8.0.1.
I just noticed that I can no longer use my touchpad to scroll on webpages in Firefox 8.0.1. I don't think I had this problem a few days ago, definitely not last week. I see the scroll icon but it does not scroll when I am on any webpage. At times it starts on one page until i refresh the page or click a link on the page but then it will stop scrolling.
I am able to scroll using my touchpad in Word 2010 and on the rest of my computer.
I am running Windows 7 Home Premium 64-bit and have a Dell Studio 1558 that is a year old.
I updated the touchpad driver from and it still did not work. Then tried the one directly from Synaptics and still not working.
I also updated Firefox 8 to 8.0.1 and it still does not work.
Please fix this as it is rather annoying.My scroll also doesn't work in Firefox -- but does in Excel and Word. This has been intermittent for months now. Usually, if I reboot the scroll would begin working again until for no apparent reason it quits again. Now even the reboot doesn't fix the no-scroll problem. I have Windows Vista. I even did a Firefox Update to 9.0.1.
I don't have that file on my about:config page so this solution won't work for me.
Thanks in advance for any help! -
Pages created with DWT will not scroll
I recently acquired a contract to update a site built in CS2 with tables to something that's HTML 4.01 compliant. I'm using CS5 and have updated the DWT's design, but now my pages will not scroll using the new template. I've tried using the overflow tag in several ways and locations within the DWT and style sheet itself, but to no avail. I have also created new pages from this template and they won't scroll either. I'm clearly missing something, does anyone have any ideas as to what that is? Does anyone need snippets of code?

Why are tables not HTML 4.01 compliant?
Regardless, you have to post a link to the page in question or provide the code (both HTML & CSS) for examination. The typical link you will be pointed to is the validator, so you may want to clean up as much as you can before you provide the link.

JScrollPane not scrolling to the end of JTable
Hello,
I put a table in a scroll pane, and add the scroll pane to a panel. The problem is the scroll pane does not scroll to the end of the table, it always lets me view only the first 37 rows of the table, regardless of how many rows the table actually has. Basically, the scroll pane thinks the table has exactly the same height, no matter how many lines it has. Why is this happening?
The code is something like
model = new SearchResultTableModel(false, null, null);
table = new ResultTable(model);
scrollPane = new JScrollPane(table);
mainBox.add(scrollPane);
If this is important, the table is a bit more complicated, I subclass JTable, use a custom TableModel, several types of cell renderers / editors, so maybe this is why it behaves so strange. How could I tell the scroll pane the table is actually larger?
Thank you very much, any ideas are highly appreciated,
Regards from Romania,
AdiHi,
fireTableDataChanged() is the easiest way to do it, but also that one, that forces JTable to rerender all visible cells, regardless the fact, that they are already displayed and would not need rerendering - if you add a row - for example row 7 - do fireTableRowsInserted(7,7); instead - so JTable will only render this single row if it is visible in the viewport. If you add a couple of rows, for example row 7 to 227, do fireTableRowsInserted(7,227); - always fire only the correct notifications accordingly to the changes you make, in order to keep the performance of JTable high.

Any suggestions?First, see this discussion. If the solution suggested there doesn't work for you, continue.
If you've installed a Mail plugin called "Mail Unread Menu" and you know how to remove it, please do that, then quit and relaunch Mail. Test. Otherwise, see below.
Back up all data.
1. Triple-click anywhere in the line below on this page to select it:
~/Library/Mail/Bundles
Right-click or control-click the highlighted line and select
Services ▹ Open
from the contextual menu.* A folder may open, or you may get an error message that the item can't be found. Either result is normal. If the folder does open and has contents, move the contents to the Desktop. Relaunch Mail and test. If there's no change, put the contents of the folder back and quit Mail again.
2. Repeat with this line:
/Library/Mail/Bundles
This time you may be prompted for your login password when you remove the items. Make sure they're removed from the folder and not just copied to the Desktop. If necessary, copy them first and then move the originals to the Trash.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return. -
Has anyone had an issue with FindText not scrolling in Acrobat X?
I wrote some code for Acrobat 8 using C# that used AcroAVDoc 's FindText method to search for a particular phrase so that I may find the page the text it was on and its location on the page so that I can insert an image at that location. This worked great, the FindText method returned true when it found the text, scrolled to the page it was on and selected the text. In Acrobat X, I can not reproduce this. It finds the text but does not scroll or select.
Has anyone had this issue? If so, how did you resolve it?
Below is the code snippet that worked in Acrobat 8:
try
Acrobat.CAcroApp app = new AcroApp();
Acrobat.CAcroAVDoc doc = new AcroAVDoc();
object jso;
app.Show();
//Open For Searching
if (doc.Open(PdfDocument, ""))
Thread.Sleep(AcrobatDelay); //WaitForAcrobatToLoad
bool found = doc.FindText(SearchTerm, 0, 0, 0);
if (found)
CAcroAVPageView pv = doc.GetAVPageView();
int PageNum = pv.GetPageNum();
CAcroPDDoc pdDoc = (CAcroPDDoc)doc.GetPDDoc();
jso = pdDoc.GetJSObject();
Thanks in advance for any help.Hi,
I just found these work arounds.

IPhone Simulator will not scroll
I've the latest Xcode, Mac OSX, and Safari. When I use the iPhone Simulator to test a Drupal website I've developed the simulator will not scroll any of the pages. I'm using a MacAir with no mouse. What do I have to do to scroll?
I suspect you have the Voiceover accessibility feature turned on. The easiest fix is to connect your phone to iTunes. Select the "Configure Universal Access" button in the summary pane and turn Voiceover off.

I bought a new iMac last year and was busy so I didn't use it much. Along with a trackpad and a wireless mouse. The mouse works as expected however the trackpad will not scroll a Safari Window.
It will scroll when connected to my 5 year old Macbook. I took the trackpad to an Apple store and it worked fine on the geniuses laptop there.
It just doesn't scroll a windwo on my iMac. I have experimented with the settings endlessly but it just doesn't scroll. I tried calling tech support and they said take it to the apple store which I did. I just now noticed that in a safari window the slide bar disappears when I use the trackpad. but reappears wheh I use the mouse.
I hope I don't have to lug the entire computer back to the Apple store. It seems like a software issue to me. Any suggestions welcomed here.how do you try to scroll ?
some people are used to trackpads scrolling when they move their finger out in the right side or the likes
with newer macs one scroll by placing 2 fingers beside eachother and moving them up and down
