Programatically click the table header?

hello
how do you programatically click the table header? i have some panels in a table...there is a button in each one that says "remove" to remove that panel from the table. when i tablemodel.removeRow(thisRow), it sorta does: the row is gone, the overall count is reduced, but it displays wrong until i click on the table header..
for example..if it lists job 1, 2, 3, 4, and 5. if i delete job #2. 1, 2, 4, 5 are left. when i click on the header it shows: 1, 3, 4, 5 as it should. any query i make to what is there before the header shows the same thing: 1, 2, 4, 5. wierd eh? so i need a way to click on that header programatically. i know its a hack, but i cant figure out why its not deleting the right oen for that little time before the header-click.

When you say table, I'm assuming you mean JTable since you're using
a TableModel.
You might try just encouraging the table to redraw itself as that's
probably what is happening when you click the header. I've noticed
that is often required when removing components. Anyways, I'd try
experimenting with calls to
repaint() and/or
validate() or invalidate()
on the JTable or its parent and see what happens.

Clicking the table header column programmatically

Hi
For sorting of the JTable I've used the TableSorter API provided in this site. What I need to do is by clicking on another panel the panel containing the JTable should be displayed sorting the respective column. So what I need to do is click the table header column programmatically. Do you know how can I do that.
Thanx.

Take a look at setSortingStatus function in TableSorter.
If you want ascending sort just call:
setSortingStatus(columnIndex, 1);This is the code executed when you press table header, it might give you some more insight:public void mouseClicked(MouseEvent e) {
            JTableHeader h = (JTableHeader) e.getSource();
            TableColumnModel columnModel = h.getColumnModel();
            int viewColumn = columnModel.getColumnIndexAtX(e.getX());
            int column = columnModel.getColumn(viewColumn).getModelIndex();
            if (column != -1) {
                int status = getSortingStatus(column);
                if (!e.isControlDown()) {
                    cancelSorting();
                // Cycle the sorting states through {NOT_SORTED, ASCENDING, DESCENDING} or
                // {NOT_SORTED, DESCENDING, ASCENDING} depending on whether shift is pressed.
                status = status + (e.isShiftDown() ? -1 : 1);
                status = (status + 4) % 3 - 1; // signed mod, returning {-1, 0, 1}
                setSortingStatus(column, status);
        }

Clicking on table header throws exception

I'm using Windows Look and Feel. I made a table and applied the custom renderer to the table header. When I click the table header it throws a NullPointerException relating to the plaf.
javax.swing.plaf.basic.BasicTableHeaderUI$MouseInputHandler.mouseClicked(Unknown Source)+
Anybody any Idea. Adding the mouse Listener solves this problem but I dont want to use the listeners just for that reason.

How to add the Row count(number of rows in table) in the table header?

Hi,
I'm having a table. This table is viewed when i click on a search button.
<b>On the table header it should dynamically display the number of rows in the table, i.e., the row count.</b>
How to do this? could any one explain me with the detailed procedure to achieve this.
Thanks & Regards,
Suresh

If you want to show a localized text in the table header, you should use the <b>Message Pool</b> to create a (parameterized) message "tableHeaderText" like "There are table entries".
Next, create a context attribute "tableHeaderText" of type "string" and bind the "text" property of the table header Caption UI element to this attribute.
Whenever the table data has changed (e.g. at the end of the supply function for the table's data source node), update the header text:
int numRows = wdContext.node<TableDataSourceNode>().size();
String text = wdComponentAPI.getTextAccessor().getText
IMessage<ComponentName>.TABLE_HEADER_TEXT,
new Object[] { String.valueOf(numRows) }
wdContext.currentContextElement().setTableHeaderText(text);
Maybe you want to provide a separate message for the case that there are no entries.
Alternatively, you can make the attribute calculated and return the header text in the attribute getter.

Sorting the report by clicking the column header

Hello,
Currently working on a requirement where i need to sort the report by clicking the column header. Can anyone please help me on this.
Suppose i have 3 colums deptno,dname,sal fields in my report. if i click deptno column header, report has to sort by deptno.Like that i need for other columns also.
Any help is really appreciated
Thanks
Ram

Hello,
You can sort the fields using method suggested by Cauvery. However if you would like to have Ascending/ Descending sort order control at column header, then would require to implement few additional steps.
First do the sorting of field using the way suggested by Cauvery. Once sorting is done, right click on the column name and select the option ' Bind Sort Control'. You will see the sorted field in the window. select the field and click ok.
Now you would get 2 arrows on column. If you click upper arrow, fields would be sorted in Ascending Order and if you click on down arrow, it would be in Descending order.

Name      I-number       department
to stay on the screen, and have only my table as scrollable?

But the prob is the table that is inside scroll cotainer is displaying in the next row instead of the new row.
Is there any solution of this.

Fixing the Table Header in the default JSF Table

I am using the default JSF Table in Sun JS Creator (Version JSC 2 EA 2) with a
Scroll Bar Option (instead of Pagination Control). However I have not
been able to fix the table header and scroll only the data rows in the
table.
I have tried to use CSS style for table header, but it has not worked
either. Where do I set the CSS style - in JSCreator JSF Datatable or
JSCreator Table component, neither seems to work for me?
Is there any other way to fix the table header default JSF Table in Sun
JS Creator?
Using the scroll bar is critical user requirement for me and fixing the
table header will ensure that I can use the default JSF Table in Sun JS
Creator, alternatively we will have to use some other JSF table e.g.
from myFaces or an HTML Table and lose on the productivity benefit of
JSCreator.

How to set a Excel-like column-Filtering in the Table Header using swings

Can anyone pls help me....
Thanks

You can [get the table column header|http://java.sun.com/javase/6/docs/api/javax/swing/JTable.html#getTableHeader()] and add a mouse listener to it which waits for a popup menu trigger to display a popup menu.
In that popup menu, you can display a list which contains the unique values of the column which was clicked on. Once a value is
selected, you can filter the rows using that value.

Has anyone tried changing the color of the table header in Dynamic Pages?

When you generate the sample Dynamic Page you get a table header with the color of #C0C0A0.
Has anyone ever found where this value is coming from within the database ?
I'd like to change it so I can control the background color in the TH tag for Dynamic Pages.
TIA
Mark.

You probabli dispay the data as
<oracle> select empno,empname from scott.emp</oracle>
However, you could do it like this:
<oracle>
being
htp.p('<table>');
htp.p('<tr>');
htp.p('<td bgcolor=#ffaabb>empno</td>');
htp.p('<td bgcolor=#ffaabb>empname</td>');
htp.p('</tr>');
for c in (select empno,empname from scott.emp) loop
htp.p('<tr>');
htp.p('<td>');
htp.p(c.empno);
htp.p('</td>');
htp.p('<td>');
htp.p(c.empname);
htp.p('</td>');
htp.p('</tr>');
end loop;
htp.p('</table>');
end;
</oracle>
htp is package in sys schema in oracle.

How To apply bold property to the table header

Hi All,
Please advice me that how to apply bold property and backgroud color to the table column header.?
Any help is greatly appreciated.
Thanks in advance.
Sathya Rani M

You can loop through the rows and apply the "fillColor" property for rows. Loop length is the "headerRowCount" of the table.
In the same loop you could also loop (a loop within a loop) through all cells of a row and set its "texts" obejct, which is an array, to the text style you wish. Or you could apply a paragraph style or a character style, that is pre-defined.

***How to Invoke backing bean method by DOUBLE-CLICK the table ROW!!***

Hi,
How can I collect the selected row value & navigate to next page by DOUBLE-CLICK the result table row.
My application got searchResult page where I am displaying the list of user in result table. Then selecting any one row and navigating to master details page by clicking the continue button. Button Action method will collect the selected row userID which I am forwarding to the masterDetails page.
Same functionality I want to do by double click the row instead of clicking the button!!. I want to trigger the backing bean method if the user double click the row basically. Please help me in this how to do this?
Current button action method:
*public String userSelected() {*
FacesCtrlHierNodeBinding binding = (FacesCtrlHierNodeBinding) searchResultTable.getSelectedRowData();
currentRow = binding.getRow();
selectedNetID = (String) currentRow.getAttribute("netid");
System.out.println("selectedNetID -->"+selectedNetID);
requestContext.getPageFlowScope().put("netid",selectedNetID);
return "continue";
*}*

Puthanampatti ,
Yes, I am using the same. Below is my code. I am trying to get the object of the MAIN jspx page region (where I am displaying the fragments) and refresh the one. But cant able to get the object for the region it is returning null. without refresh seems the navigation wont work.
public void doDbClick(ClientEvent clientEvent) {
FacesCtrlHierNodeBinding binding = (FacesCtrlHierNodeBinding) searchResultTable.getSelectedRowData();
currentRow = binding.getRow();
selectedNetID = (String) currentRow.getAttribute("netid");
System.out.println("selectedNetID -->"+selectedNetID);
requestContext.getPageFlowScope().put("netid",selectedNetID);
try{
FacesContext facesCtx = FacesContext.getCurrentInstance();
NavigationHandler nh = facesCtx.getApplication().getNavigationHandler();
nh.handleNavigation(facesCtx, "", "continue");
System.out.println("region obj -->" +facesCtx.getViewRoot().findComponent("advse1"));
// Refresh the current region; advse1 is the id of the region component inside jspx page
AdfFacesContext.getCurrentInstance().addPartialTarget(facesCtx.getViewRoot().findComponent("advse1"));
catch(Exception e){
System.out.println("Error is: " +e);
Is this correct coding to get the region object?? actually the "result table" and "Master details" are 2 different fragments which are linked with task-flow and the task flow is part of main jspx page as a region. I am using that region ID to get the obj, but cant able to get so....!!! any idea
