Problem with JTable Header

I want to show a JTable in a scrollPane , But i don't want to show its header.
i have tried table.getHeader().setVisible(false) but it shows a gap on table top which is not desired.
If anybody can help me.

If I remember correctly, if u set the headervalues to null they wont show.

Selection Problem with JTable

Hello,
i have a selection problem with JTable. I want to allow only single cell selection and additionally limit the selection to the first column.
I preffered the style from MS Outlook Express where you can select the email accounts to edit.
It is a table like this:
Account name |   Type |   ...
--------------|---------|---------------------
Hotmail       |   POP3 |
GMX           |   IMAP |The selection should be only avaibable at 'Hotmail' or 'GMX' - not at 'POP3', 'IMAP' or as complete row selection.
Please help me!
Thanks.

I don't know If I can fix your problem, but
I know just that it works on my PC.... It's very very
slow... I don't know how to insert PageSetUp option... I have to study the problem.....
However I don't think it's a hard problem....
I want ask to you if you have found some problems when you are in Editing mode in a cell.....
in the jdk1.2 version I could save while was in editing mode using the editingStopped method.
It permit to update all data .... also the data in the cell I was editing.
in the jdk 1.3 if I use this method It doesn't work properly... It maybe destroy the content object in the Cell..... because I'm able to print all the table except the editing cell (it throw an exception...)
What's changed????
I don't know...
Can u help me?

A problem with JTable

Hi !
I have a problem with JTable - would like to use this component as a simple list of rows taken from a database : don't want to be able select or set a focus to a column - want only to be able select and set focus to a row ( just like in the menus). How to disable "focusability" for a cell with JTable ? Could You help me ?
thnx in advance

The Border is changed by the renderer, depending on whether the cell has focus or not. So you will need to create custom renderers without a Border. Something like:
class NoBorderRenderer extends DefaultTableCellRenderer
     public Component getTableCellRendererComponent(
          JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
          super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
          setBorder(null);
          return this;
}

Problem with JTable with JCheckBox as Header

Hi,
We have a JCheckBox as JTable Header. And respective data in that column also check boxes. For data check boxes, just i am sending Boolean object to object[][] data array. I am getting check Boxes as data components.
For Header, i have create a TableRender object which is returning JCheckBox.
Here my problem is,
1) When i select a Header check box, all the check boxes are getting selected.
2) Now we can reselect an data Check Box. When i reselect any data checkBox, Header CheckBox should be reselected. This is not happening. I was tried lot. Can any body give a solution to solve this problem.
Please .... Please ...
Thanks
Mohan

just call this method with null param on the JTable
table.setTableHeader(null);

Problem with JTable and JPanel

Hi,
I'm having problems with a JTable in a JPanel. The code is basicly as follows:
public class mainFrame extends JFrame
        public mainFrame()
                //A menu is implemeted giving rise to the following actions:
                public void actionPerformed(ActionEvent evt)
                        String arg = evt.getActionCommand();
                        if(arg.equals("Sit1"))
                        //cells, columnNames are initiated correctly
                        JTable table = new JTable(cells,columnNames);
                        JPanel holdingPanel = new JPanel();
                        holdingPanel.setLayout( new BorderLayout() );
                        JScrollPane scrollPane = new JScrollPane(holdingPanel);
                        holdingPanel.setBackground(Color.white);
                        holdingPanel.add(table,BorderLayout.CENTER);
                        add(scrollPane, "Center");
                        if(arg.equals("Sit2"))
                                if(scrollPane !=null)
                                        remove(scrollPane);validate();System.out.println("ScrollPane");
                                if(holdingPanel !=null)
                                        remove(holdingPanel);
                                if(table !=null)
                                        remove(table);table.setVisible(false);System.out.println("table");
                        //Put other things on the holdingPanel....
        private JScrollPane scrollPane;
        private JPanel holdingPanel;
        private JTable table;
}The problem is that the table isn't removed. When you choose another situation ( say Sit2), at first the table apparently is gone, but when you press with the mouse in the area it appeared earlier, it appears again. How do I succesfully remove the table from the panel? Removing the panel doesn't seem to be enough. Help is much appreciated...
Best regards
Schwartz

If you reuse the panel and scroll pane throughout the application,
instantiate them in the constructor, not in an often-called event
handler. In the event handler, you only do add/remove of the table
on to the panel. You can't remove the table from the container
which does not directly contain it.
if (arg.equals("Sit2")){
holdingPanel.remove(table);
holdingPanel.revalidate();
holdingPanel.repaint(); //sometimes necessary
}

Problem with my header

I have a website setup and running for at least a year. We just changed to a dedicated server and for some reason I am experiencing trouble with the header image of the general web. When I load the page the header is now loading behind the flash window and then on a second hit of the enter key will load to the top where it should be. This site has been up and running for almost a year, can't figure why the problem now. But need to know what I need to look at. The flash content has been there since the beginning too.
Any help would be appreciated.
I have a copy at http://www.nepa-alliance.org/index2.htm
Would appreciate any guidance. One more thing if I may. I ran it through the w3c validator and got a terrific amount of errors for the code "<", "&", "> in the various scripts in the head. It recommends replacing it with the "&lt" , & but won't this screw up the script.
Thanks for any help.

Chances are you site has always been this way but you were unaware of the extent to which your APDivs / Layers / code validation errors have tripped you up bigtime.

Scrollbar problem with JTable.

Hi,
I have 45 columns in a JTable. Please remember this is customize, we can change the number of columns dynamically, at max they can be 2 columns.
i was having a problem with display the columns names in my Frame. I posted at http://forum.java.sun.com/thread.jspa?threadID=5167358&messageID=9641265#9641265
I got the solution. Thanks for that.
But as i said these columns are customized.
when i am having 2 columns in my JTable, table.setAutoResizeMode( JTable.AUTO_RESIZE_OFF ); is behaving differently, it's not occupying the complete JFrame. Lots of space is left out beside these 2 columns.
When i comment this line, then those 2 columns are occupying my complete Frame.
these two colmns should occupy my complete Frame and if i select 45 columns i should get scroll bar at botton with complete column NAMES.
Hope i am clear.

Thank You camickr, it's serving my purpose.
Just for a clarrification :
table.setAutoResizeMode( JTable.AUTO_RESIZE_OFF );
table.setAutoscrolls(false);without using these lines also my purpose is serving.....then y do we need above two lines of code. r they necessary
i mean, this snippet is sufficient.
public boolean getScrollableTracksViewportWidth()
     return getPreferredSize().width < getParent().getWidth();
}

Problems with JTable Renderer

I have a problem with applying a custom renderer. I know the renderer works so thats not the problem. If I do like this:
DefaultTableModel aDefaultTableModel = new DefaultTableModel(data, columnNames);
it works. But if I do like this:
DefaultTableModel aDefaultTableModel;
aDefaultTableModel.setDataVector(data, columNames);
is doesn't, why?

I think maybe it's not the renderer at all. It may be my custom TableModel thats causing problems. Now this doesn't work:
private JTable aTable;
private CustomTableModel aTableModel;
public MyProgram() {
aTableModel = new CustomTableModel();
aTable = new JTable(aTableModel);
aTableModel.setData(data, columnNames);
private class CustomTableModel {
private String[] columnNames = null;
private Object[][] data = null;
public CustomTableModel() {
columnNames = new String[0];
data = new Object[0][0];
... snip
public void setData(Object[][] data, String[] columnNames) {
this.data = data;
this.columnNames = columnNames;
fireTableDataChanged();
... snip
Now, why doesn't that setData method work??

Problems with JTable

Hi All,
I am facing some problems in JTable :
1) How to remove all lines between cells, neither i should have column nor row lines....there should not be any lines between any cell at all.
2) If i select a perticular cell, complete row is getting selected with a blue background, that should not happen at all.....row should not get select....
3) How to make a cell non editable.
Regards,
Ravi

1) Read the API. Check out the set??? methods until you fine what you want
2) Read the API. Check out the methods that deal with row and column selection
3) Override isCellEditable(...) method of JTable or DefaultTableModel

Problems with http header "Content-Location"

Does anyone know how to override the
"Content-Location" http header. We are having issues with search engines and this header being returned from Apache/oc4j. In a nutshell, I have a site that uses the
Struts framework, where the actual urls submitted would be for example
(http://mysite/home.do), where ".do" is just a servlet mapping. When we have
tried to follow the one link that has been spidered, it actually contains
the full path that appears in the "Content-Location" header (i.e.
http://mysite/web-inf/jsps/bogus.jsp) which in this case can't even be
accessed. The feedback we get from third-party utilities that try to spider
the site is that it is stopping because it has already indexed "bogus.jsp",
which in reality will always appear since it is a template, where the actual
urls will be different as is above.
Because the "Content-Location" header is being returned to any
client hitting the site, search engine spiders stop indexing at the first page because the value in "Content-Location" is the same.
Solutions tried:
mod_headers in Apache - have tried "Header unset"
HttpServletResponse.setHeader()
Any help would be appreciated

Hi there,
i'm having a similar problem to this when trying to run some web page speed optimisation software...
i think the issue also causes problems with the Opera browser (although this may have been fixed in the latest version).
anybody any ideas how to stop the header being sent in the response?
many thanks,
Andy

Problem with column heading sorting

I have a problem with a classic report.
I created a simple report. We want to sort the report, when we click the column heading. But when we cklick on the column heading, nothing happens. In firefox we get the error "apex.jQuery.datepicker is undefined".
When we created another simple report and connect against another database (but the same web-server), we can sort the report, when we cklick a column heading. On both databases we installed the same apex version (=4.0.1.00.03).
on "apex.oracle.com" (workspace:ama / user:demo / pwd:demo) I created an example.
what is wrong?? Can anyone help me ??
Thanks
Robert

Hi Jari,
yes, you are right. I changed my query. I attempted to find a solution and so I changed the query several times => I used other tables, with or without date columns, with or without columns in the select and so on.
You said, the problem is the authentication scheme. It crossed my mind that I do another change:
during the creation of my application apex created a login page => page 101. For my example application I don't need a login page, and so I droped the page. After starting the application I saw the error message "page 101 not found ". So I searched for a property where apex definies the "start page" respectively "login page". But I don't found anything. Then I looked into the export file and searched for "101". I found the package procedure "wwv_flow_api.create_auth_setup" and the parameter "p_invalid_session_page", which receive the value "101". In apex the property "Session Not Valid Page" was blank. So I inserted the page number "1" (=the first and sole page in my application).
After the explained changes I could start my report.
I don't know, whether these informations help to find the problem!
Regards
Robert

Problem with JTable in a JScrollPane

Hello all,
I have a problem using JTable, that the number of columns is very big,
and the JScrollPane shows only vertical ScrollBar, isn't there any way to show a horizontal ScrollBar, to show the other columns without being bunched.
Thanks in advance.

table.setAutoResizeMode( JTable.AUTO_RESIZE_OFF );

Flipping problems with JTables

I have a JTable (with scroll bar ) and a JButton inside a Jframe.
When I push the JButton another JFrame appears with another JTable inside.
The problem is that when I close the upper JFrame and I try to move the scroll bar of the JTable inside the father JFrame it starts to flip doing an horrible effect for the general lauyout.The solution it could be overwrite the paint method....but actually for my Java knowledges is impossibe. Help !

Sorry I mean flashing problems (not flipping.)
The code is:
JPanel p1=new JPanel();
Label lab1=new Label(" LABORATORIO ANALISI CLINICHE");
Label lab2=new Label(" Dr.ssa xxxxxxxxxxxx ");
     Label lab3=new Label(" C/o xxxxxxxxxxxxx ");
     Label lab4=new Label(" Via xxxxxxxxxxx nr 5/7");
     Label lab5=new Label(" 86100 xxxxxxxxxx");
Label lab6=new Label(" tel. xxxxxxxxxx");
     p1.setLayout(new GridLayout(6,1));
p1.add(lab1);
p1.add(lab2);
p1.add(lab3);
p1.add(lab4);
p1.add(lab5);
p1.add(lab6);
Report myReport=new Report(tableModels[p.getSelectedIndex()],"Printer Manager",p1);
Actually Report is a class that prepare a JFrame with a JPanel and inside the JPanel there is a JScrollPane that get the JTable.That's the code for the Report class:

do you think that there are problems because the print method ? or mayby because I clipped the graphics area ?
