How to display column header of a JTable in JScrollpane's RowHeader

Can anyone tell me if it's possible to display the colum headers of a JTable which acts as the row headers of a JScrollpane object?
If the answer is yes, could he/she point me to the right direction?
Thanks,

I'm guessing the answer is no because the column header is layed out horizontally and a row header is layed out vertically. But it should be easy enough to test:
scrollPane.setRowHeaderView(table.getTableHeader());
Its not hard to create your own row header. Search the forum using "+setrowheaderview +camickr" to find examples I've posted.

How to get column header text in IWDTable

Hi
Just want to know how to get column header name in IWDTable.
I know that you can get it with
IWDAbstractTableColumn[] groupedColumns = table.getGroupedColumns();
for (int i = 0; i < groupedColumns.length; i++) {
     IWDAbstractTableColumn column = groupedColumns<i>;
     column.getHeader().getText();
But what if text isnt set on header level but its rendered from cellEditor model binding (im not sure if its like that).

Finally after your suggestion i did it with this code
String header = column.getHeader().getText();
                   if ((header == null || header.length() == 0) && column instanceof IWDTableColumn){
                        IWDTableCellEditor tableCellEditor = ((IWDTableColumn) column).getTableCellEditor();
                        if (tableCellEditor instanceof IWDTextView){
                             String bindingPath = ((IWDTextView)tableCellEditor).bindingOfText();
                              StringTokenizer tokenizer = new StringTokenizer(bindingPath,".");
                              String token = "";
                              IWDNodeInfo nodeInfo = context.getNodeInfo();
                              while (tokenizer.hasMoreTokens()){
                                   token = tokenizer.nextToken();
                                   if (tokenizer.hasMoreTokens()){
                                        nodeInfo = nodeInfo.getChild(token);
                              IWDAttributeInfo attribute = nodeInfo.getAttribute(token);
                              ISimpleType simpleType = attribute.getSimpleType();
                              simpleType.getDescription();
                             header = simpleType.getDescription();

How To Display Table Header in JTable

Hi,
I have a tree node that is a JTable. It displays the cells, but not the header or the left hand side of the table.
Here is my code ...
Anyone got any ideas?
public SimpleTree() {
super("Creating a Simple JTree");
WindowUtilities.setNativeLookAndFeel();
addWindowListener(new ExitListener());
Container content = getContentPane();
JTable table;
     String columnNames[] = { "OrderID", "CustomerID", "EmployeeID", "Order Date", "Shipped Date" };
     String dataValues[][] =
          { "34", "234", "67","12/02/2002", "16/04/2002" },
          { "-123", "43", "853","12/02/2002", "16/04/2002" },
          { "93", "89.2", "109","12/02/2002", "16/04/2002" },
          { "279", "9033", "3092","12/02/2002", "16/04/2002" }
     table = new JTable( dataValues, columnNames );
     table.setEnabled(true);
     table.isCellEditable(4,4);
     table.setShowHorizontalLines(true);
     table.setShowVerticalLines(true);
     table.getTableHeader().setForeground(Color.black);
     table.getTableHeader().setBackground(Color.lightGray);
     table.getTableHeader().setReorderingAllowed(true);
     table.getTableHeader().resizeAndRepaint();
     JTableHeader header = table.getTableHeader();
header.setUpdateTableInRealTime(true);
header.setReorderingAllowed(true);
     Object[] hierarchy =
{ "Orders",
new Object[] { "Orders",
                              table},
new Object[] { "Prodcuts",
new Object[] { "",
table },
"Employees",
"Suppliers" };
     DefaultMutableTreeNode root = processHierarchy(hierarchy);
     JTree tree = new JTree(root);
     tree.putClientProperty("JTree.lineStyle", "Angled");
     tree.setCellRenderer(new MyTreeCellRenderer(table));
     tree.setCellEditor(new SimpleTreeCellEditor(table));
     tree.repaint();
     table.repaint();
     tree.setRowHeight(-2);
     tree.setEditable(true);
     content.add(new JScrollPane(tree), BorderLayout.CENTER);
     setSize(275, 300);
setVisible(true);

The column header is a different component of the table component. You can get this component directly and place it wherever you want in a container, just get them from the JTable:JPanel aPanel = new JPanel( new BorderLayout() );
JTable myTable = xxx;
aPanel.add( myTable.getTableHeader() , BorderLayout.NORTH );
aPanel.add( myTable, BorderLayout.CENTER );

JTable not displaying column Heads

The table header is shown automatically when you add the table to a scrollpane and then display the scrollpane in a panel. You use the following code to build the table/scrollpane:
// display table with ResultSet contents
jTable1 = new JTable (rows, columnHeads);
JScrollPane scroller = new JScrollPane(jTable1);
but, you add the table to your panel NOT the scrollpane:
this.add(jTable1, new GridBagConstraints(0, 2, 2, 1, 1.0, 1.0
,GridBagConstraints.CENTER, GridBagConstraints.BOTH, new Insets(12, 25, 0, 22), 522, 281));
You should be adding the scrollpane to you panel.

Problem in displaying Column Heading using JTable

I am using JTable component in my applet. I am trying to retrieve records from a database and want to display the same in the table using JTable component. In that procees my data is shown in the table but I am not able to display the column heading.
Please suggest.

you could user JScrollPane to show the column's head.
if you don't want to use JScrollPane ,you should use the getTableHeader() method and add the header into the pane

How to Link column header only in classic Report in APEX 4.1

Hello Everybody,
Probably there is a simpler way to do this, but I am not sure. I want a link on column header in Report on a specific column. The link will take me to new region or a page.
How to achieve this in APEX 4.1
Theme : Blue 2
Database 11g
I see there is a column link opiton, but that creates link for every row in that column on a specific icon, I just want link on a title of the column in Classic Report.
For Example,
if there are two columns Name and Client ID, which has 10 records to display on a classic report. I wan the link on Client ID on header only not on the records.
Can anybody provide some simple solution for this.
Thanks,
--CP
Edited by: cpora007 on Jun 22, 2012 10:38 AM

Hello,
I didn't understand, what do you mean by default it is going to sort popup. I have a classic report based on SQL, which generates a report with static header, there is no sort or any other link on that.
I added a link in column header name with an anchor. It works and takes to the new page.
But it is not a proper solution. A solution based on Jquery dynamic action is preferable. Also the preferred option is that the link opens a hidden region of the same page at the same location of the report and the report gets hidden. after the procession on the form region and submitting the update/ insert process. the report region shows up with the change data.
Moving on to new page is 2nd option, if the first do not work.
In the JavaScript, put: apex.submit("GO_TO_MY_OTHER_PAGE");
On the page, create a Branch to the Second page. Set the condition to Request=Expression 1. Set the request to "GO_TO_MY_OTHER_PAGE"
On which page I need to create a branch?, Is it on the report page or the form page.
Thanks a lot for the response. I appreciate your kind efforts in this regard.

How to pass column header as a parameter in Validation Expression (APEX4.0)

Hello
I created a new Page validation in APEX4.0 ( not 4.1 ).
(1) Type : Function Returning error text
(2) Validation Expression 1 :
begin
return validate_name ( p_c=> #COLUMN_HEADER# ,p_c_value=> to_date(:p26_LEAVE_FROM,'dd/mm/yyyy') );
end;
note: the validate_name is an oracle pl/sql procedure which takes two input parameters ( column header name and actual value ) and return a specific error message ( to that column ) or NULL.
(3) In the Error Message section, I left Error Message blank ( as the app ignored the mssage but used the one returned from the above function)
However, I chose "The Error display location" to be inline with field and notification" and Associated Item to be "p26_LEAVE_FROM".
My question, it worked if I hard coded the actual column header "LEAVE FROM" , but it didn't work if I used the above #COLUMN_HEADER# in Validation Expression. Can I avoid hard coding as the column header might be changed one day. Is there a better way to deal with multiple column validations with different error message for each column ? It seems that I will have to create similar page valiation for each column to be validated.
Thanks for your advice.

You want something like this:
DECLARE
lio_success VARCHAR2( 2000 );
li_id        NUMBER;
li_dep_id    NUMBER;
li_sel_id := NUMBER;
li_date DATE;
lo_date DATE;
lio_return_message xyz_bpe_rec_fn.xyz_bpe_rec_col;
l_ret xyz;
BEGIN
lio_success := 'some value';
li_id := NULL;     -- or some number
li_dep_id := NULL; -- or some number
li_sel_id := NULL; -- or some number
li_date DATE := sysdate;
lio_return_message.col1 := somevalue;
lio_return_message.col2 := somevalue;
lio_return_message.coln := somevalue;
l_ret := get_xyz( lio_success

How to change column heading in line item report

Not possible through standard I guess.
Enhancement you should be looking is COOMEP01 which includes the component EXIT_SAPLKAEP_009
i.e., Line Item Reports: Customer-specific Formatting of the Lists.You use this enhancement to modify column headings.

How to display dynamic header title in the report?

I have a req to display dynamic header title in the report.
When a id is entered in the prompt text, it will display the user data based on that user_id.
so similarly....the header title should vary each time when you select different user_id.
How can we implement this?

Zack..I have several projects listed under several project id's...
so when a user selects project id 00164 then it should display something like "Project document for Jon Doe"
again when the user selects project id as 00192 then it should display something like "project document for Zimmerman"
Did you get it??
