Solaris 9 & JTable Scrolling
Hi,
I've got an application that runs fine on Windows and earlier Solaris versions, but has a problem on Solaris 9. The application has a JTable in a JScrollPane that displays dynamically captured data. In Solaris 9, the table is not repainting properly when scrolling up/down by a row or page. The old information is not erased before writing the new information, so it becomes a big garbled mess when scrolling. When the block is grabbed with the mouse and moved, the table is repainted properly.
Has anyone seen this? Any ideas for workarounds?
many thanks for your test!
I need to install it in the next couple of weeks so I will keep this issue in mind.
Perhaps you can let the BU to update the ReadMe with this information - otherwise it could result in some frustration when installing it on solaris 9...:-)

I am having a problem with my JTable scrolling to show the newest added row. I have it working, but it jumps. Here is my problem.
I have the enter key acting like the tab key. I can force the scroll to the active cell but it jumps to row 0 for just a split second.
I know the problem is the way that I handle the Enter key. When I press enter I drop a cell down but then I force it back up.
Does any one know how to fix this? Here is some of the code that I am using...
if (event.getKeyChar() == '\n')
int r = tblDetailEntry.getSelectedRow();
int c = tblDetailEntry.getSelectedColumn();
if(r == 0)
r = curBill.billDetail.size();
c--;
if(r <= curBill.billDetail.size())
r--;
if(c == curBill.CODE)
c = 0;
if(r == curBill.billDetail.size() - 1)
detailEntry.addLine();
r = curBill.billDetail.size() - 1;
else
r++;
Rectangle rect = tblDetailEntry.getCellRect(r, 0, true);
tblDetailEntry.scrollRectToVisible(rect);
tblDetailEntry.editCellAt(r,c + 1);
tblDetailEntry.setRowSelectionInterval(r,r);
tblDetailEntry.setColumnSelectionInterval(c + 1,c + 1);
}My app is a bit more complex. It includes search criteria (Textboxes) and a
submit button which will write a dynamic SQL statment, execute and fill a table > thin an internal scrollpaneIt doesn't matter that you are using a "dynamic SQL statement". Whats important is how you build your TableModel and the TableModel you are using. I gave you an example that will use the DefaultTableModel and will work for a single row or 1,000 rows in the ResultSet.
Your question didn't state whether you are using the the DefaultTableModel or a custom TableModel. If you are using a custom TableModel, then chances are you have an error in you TableModel.
In no way am I asking for you or anyone else to supply me with code. Only a
possible step in the right direction. This is exactly what my example did. It proved to you that it works. So you look at your code and see what the differences are between one that works and one that doesn't. The example has three basic lines of code to build a scrollable table:
JTable table = new JTable(data, columnNames);
JScrollPane scrollPane = new JScrollPane( table );
getContentPane().add( scrollPane );
I don't know how is can get any simpler than that, so I would have no idea what to suggest you are doing wrong. Are you mixing AWT and Swing components? -
Hi,
I have a problem in JTable scrolling of large data,I am getting a large data set from database, but I do not want to display all of the data at once (mainly because of OutOfMemory error).I want to display data in pages (say 50 records in each page) ,but I want to keep the vertical scrollbar position as though I have the entire data (Let's say 10,000 records) in JTable,But physically only 50 records are there in JTable. In another words,I want to give user an illusion of having 10,000 records, but in fact only 50 records are there at a time.It means if my scrollbar position is halfway,my jtable has displayed 5000 records.
I will appreciate your help.
Please email me directly at [email protected] or post your reply.
Thankshi Chuanhao,
The reason I can't get the data directly from my table model using getValueAt is that,
1) The data which I am getting from database is raw data, I have to do lot of processing,and format it in a certain way so that my JTable implementaion can understand it (My implementation of JTable takes the data as JTextArea and JButton,moreover, I have to convert the data into user readable format before I can send it to JTable for display)
2) I want to do some caching of data, for example if user has scrolled down, and then again he wants to go back by scrolling up, I don't want to get the data from database,I would like to use the same data which is in cache,Or I want to keep several pages of data ready in another thread, so that when user scrolled down, he doesn't have to wait for database fetch.
I don't think I can do all this thing if I get the data directly from table model using getValueAt.
What I want to do at this point is find some way to override the scrolling behaviour of JTable,My problem here is this,When user scrolled down to 51st record, I am fetching another 50 records(or already cached page) and wants to display it in the table afresh,But as soon as I do it, scrollbar goes back to its starting position,but I want it to stay where it was,in this way I will have place to scroll up,and user will think that he has entire set of records at his disposal.
Let me know what you think, any help will be greatly appreciated.

JTable Scroll Issue (not scrollRectToVisible)
I have a JTable that the user adds rows to. This table has a totals row as well at the bottom.
This table can get quite large and each new row they add is at the bottom (minus one for the totals row). Currently, I'm using scrollRectToVisible which works fine.
My problem is that this table has more columns then there is room for on screen.
scrollRectToVisible wants a column as well as it's scrolling to a cell, not an actual row. I've always used 0 as my column as it works but now I've had some users say that if they scroll the table to the right, then add a new row, it "jumps" back to the left. Which would be true as it's going to row x column 0. The reason this matters is because they are looking at the totals row to see what the new total will be once the row is added. Some are slightly annoyed that they have to scroll back to the right to see the new total.
Is there anyway to scroll to a row but not worry about the column?
Thanks for your help!

JTable scrolling in Windows 7 very slow compared to Windows XP
I am running the following test program on jdk-6u18. The program displays a simple 900 rows x 20 columns table with each cell being an integer 1. When I run this is Windows 7, the scrollbar handle cannot keep up with the mouse movement as I drag it up and down. But the scrolling is very smooth if I run it on a Windows XP virtual machine on the same PC. Is there any way to improve the JTable performance on Windows 7?
Thanks.

I have a JDialog with a JTable/scroll pane. The JTable has headers but no data initially.
I want to set the min size samller than the initial size.
When I try setSize/setPreferred size this is not working. It always inits to the min size.
public TheDialog(Frame parent)
super(parent);
theModel = new TheTableModel();
theTable = new TheTable(thetableModel);
Dimension size = new Dimension(100,400);
setLayout(new BorderLayout());
JScrollPane scrollPane = new JScrollPane(theTable,
JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
scrollPane.setPreferredSize(size);
scrollPane.setSize(size);
add(scrollPane, BorderLayout.CENTER);
setPreferredSize(size);
setSize(size);
setMinimumSize(new Dimension(100,20));I am fairly new to the forum
Didn't know that people cared about any feedbackWhat does being new to a forum have to do with anything?
In other words you don't believe in saying "thank you" when someone gives you help, whether in a forum or in other apects of daily life?
Maybe the following will work:
table.setPreferredScrollableViewportSize(...);If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.

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.

No horizontal scroll bar on the Jtable. In order to see long column.....
No horizontal scroll bar on the tJable.
In order to see long cell data we have to eliminate other columns of the table.
I need an horizontal scroll bar on the JTable if the data in a cell is longer.
Could somebody help me out?
Thanks in advance.in the jtable use following method :
myTable.setAutoResizeMode(this.AUTO_RESIZE_OFF);

JTable can't display column names and scroll bar in JDialog !!
Dear All ,
My flow of program is JFrame call JDialog.
dialogCopy = new dialogCopyBay(frame, "Bay Name Define", true, Integer.parseInt(txtSourceBay.getText()) ,proVsl ,300 ,300);
dialogCopy.setBounds(0, 0, 300, 300);
dialogCopy.setVisible(true); Then,I set the datasource of JTable is from a TableModel.
It's wild that JTable can diplay the data without column names and scroll bar.
I have no idea what's going wrong.Cause I follow the Sun Tutorial to code.

JTable Horizontal Scroll WHEN NEEDED fix?
Me again....
JTable in a JScrollPane When the Jtable width exceeds the scrollpane I would like a horizontal scrollbar to appear. If the Jtable does not exceed the width Id like it to fill the ScrollPane.
If I use the AUTO_RESIZE_OFF I get a horizontal scrollbar all the time. I dont want this if possible.
I did try to overwrite getScrollableTracksViewportWidth() and getPreferredSize() as suggested by work around http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4127936
However this bug is not exactly what I am having trouble with.
Anyone know what I can do for this?
Thanks
B.You're welcome.
Autoscrolling means that you can middle click on a web page and then get a scroll icon to indicate that you can move the mouse up or down to scroll the page automatically. -
Automating scrolling of a JTable when model gets updated
Hi,
I have a JTable in a JScrollPane with a table model that updates in real time and I need to keep the currently selected row on the same place on screen (for example when a row is inserted before the selected row I'd like the scroll pane to automatically scroll one row down so the selected row remains at the same location on screen).
the scrollpane before the row insertion:
row A
row B
row C
row D (selected)
row E
now 'row F' is inserted between B and C
row B
row F
row C
row D (selected)
row E
(row A is scrolled out of sigth and D remains (visually) the 4th row in the view)
Is there any easy way how to achieve this ? I tried a number of approaches but all end up with an annoying scrollpane jitter.I'd try to call JViewPort's scrollRectToVisible(Rectangle contentRect) for the JScrollPane.getViewPort() and keep the parameter Rectangle's size the same (JViewPort.getViewRect()) but adjust the y-position by amount returned by JTable.getRowHeight() + JTable.getRowmargin(). This would be done after row wuold be added and only if vertical scrollbar is visible.
Maybe this is what you have tried already. Anyway I hope this helps.
