How to get the index of children in JTree?

could you give a example please?
THANKS

Are you sure you are using JTree? (I couldn't find a method named getIndex at all!)
As I couldn't quite understand what you are getting at, one thing that would be helpful is if you refer to "How to use Trees" in The Java Tutorial:

<h:column>
     <a:commandLink
          value="#{familyAction.familyDocsByPrj}"
          action="#{homeAction.search(ROW_INDEX)}"
          reRender="rightAppPanel" />
</h:column>When clicking a row, I'd like to make a "search" depending on the selected row.
Does anybode know how to do that?
Thanks a lot :)

Thanks a lot for all your answers! :)
I finally got to do something with my little knowledge =P
I created a new class containing all the data needed for the dataTable (including a "String id").
And that's what I get:
<h:column>
     <a:commandLink
          value="#{familyAction.familyDocsByPrj.name}"
          action="#{homeAction.search(familyAction.familydocsByPrj.id)}"

How to get the index of subform in dynamic Forms??

We are creating a Dynamic Form in which there is a field "PAN number" in a block. With the Script, we are replicating the blocks. Suppose there are 10 blocks (hence 10 PAN number fields will be there) and if the user wants to enter the PAN number in any of the blocks, how can we get the index of the block on which a value has been entered?

How to get the index of the minimize point

Need to get the index of the minimize point, marked as red cycle in the attached word file.
It is a collected data from different sample devices, so the curve may change a bit each time. But the overall profile is the same, just 2 main peaks.
I tried to detect the Y difference to see when the difference values change from negative to positive.
But, there are noise as tiny peak when zoom in, shown in word file. Then tried to use median filter to make it smooth. (Maybe better method should be used.)
But there are still some bigger regional peak. Any suggestion?
Is there any labview function or better algorithm can make it. Many thanks for your help.
Solved!

A trick I often use is to sample the data with a much higher speed than needed. Then I apply some simple averaging methods or and median filter. After that I downsample the signal to a adequate rate by averaging x samples. This have been a saver for me more than once. How successful it is depends of noise character type. It just a hint as it may not be applicable in your application

How to get the index value from rich:dataTable in jsf2.0

hi,
I am developing web application using jsf2.0. In this case, I used rich:dataTable tag for display the values from mysql.
so this is working..
my problem is, How to select the perticular row or index from the datatable for another processing...
help me..
Thanks.

Hi,
You need to get the selectedIndex attribute of the drop down element, e.g.
String ind = web
               .element(
                    41,
                    "/web:window[@index='0' or @title='Our Business Web Site']/web:document[@index='4' or @name='optBody']/web:form[@name='frmOptions' or @index='0']/web:select[(@name='PathLen' or @index='2')]").getAttribute("selectedIndex");
System.out.println("Drop down index is: " + ind);
You can use the Object Browser to get the path to the element you are interested during recording.

Jamie

Is there a way to find out how to get the index of a column?

Hello,
I want to know the index of a column for example the column at the first position in a jtable is 0 so how can i get this index?
for example: the column called "surname" is index 0 but the user can move the column. So the name stays the same but the index of the column changed. I search for a method like
table.getColumnIndex("surname");

I think it really depends on what the OP is trying to do. I think the program
below offers up the possible choices pretty well.

How to get the index of a Column

Hello,
I want to know the index of a column for example the column at the first position in a jtable is 0 so how can i get this index?
for example: the column called "surname" is index 0 but the user can move the column. So the name stays the same but the index of the column changed. I search for a method like
table.getColumnIndex("surname");

So why do you post questions on multiple forums.
Like I said you are wasting peoples time. We don't know what has been suggested on the other forums. So by answering the question here we are wasting our time because you also probably got the answer on the other forum as well.

JSTL how to get the index of a ResultSet

in jsp can use like this
rs.getString(1);//rs is a ResultSet
and how to do this in JSTL?
<sql:query var="rs">
select count(*) from my
</sql:query>
${rs.rows[0].??????}

Look at the API for the classes used by JSTL: http://java.sun.com/products/jsp/jstl/1.1/docs/api/index.html
The jstl:query var object is of type javax.servlet.jsp.jstl.sql. Result
(see http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/sql/query.html for details on the sql:query tag)
The rs has the following available to it:
rs.columNames (a String[])
rs.rowCount (and int)
rs.rows (an array of sorted maps)
rs.rowsByIndex (an Object[][])
rs.limitedByMaxRows (boolean)
The ones that might be helpful are:
rs.columnNames. As a String array, with one value per column, you try to get the count of objects in the array, or iterate through them when you are reading each row (maybe not the best idea)
rs.rows returns a SortedMap for each row. As a Map, it has the size() method which would tell you how many items. But it would also let you iterate through the map getting the values.
rs.rowsByIndes, as another means of counting the length of the columns via an array
Unfortunately, all of these means at getting to the value you want do not follow the JavaBeans specs, so you can't use simple JSTL or EL to get at them.
But once again, we could use the JSP function library to get at the data ( http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/fn/tld-summary.html )
For instance, we might be able to do this:
<c:set var="colCount" value = "${fn:length(rs.rows[0])}"/> or
<c:set var="colCount" value="${fn:length(rs.columnNames)}" />
However, I have never tested this stuff (which is why I walked through the thought process here. If you follow along, and I made a mistake, you might be able to pick it up and fix it...)

How to get the index of table row without selection?

Hi all,
I have an table designed in XML view.Now i have added an change method for qty cell "valqty". When user inputs the qty in the cell and press enter this method is triggered now I want to know which index of the table is currently edited.Through which i can get the value of other cell in the same row.
NOTE: The table row doesn't have selection either multiple or single
I tried the following inside the valqty method but it now working
this.getValue();
this.getBindingContext().getProperty('PRD_NUM');
<Table id="idProductsTable"
inset="false"
items="{oModel>/deliverylist}"
visibleRowCount= "7"
mode="MultiSelect"
modeAnimationOn="true">
<headerToolbar>
<Toolbar>
<Label text="Products"></Label>
</Toolbar>
</headerToolbar>
<columns>
<Column
minScreenWidth="Tablet"
demandPopin="true">
<Text text="Order" />
</Column>
<Column
minScreenWidth="Tablet"
demandPopin="true">
<Text text="Quantity" />
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<Text text="{oModel>PRD_NUM}" />
<Input value="{oModel>DEL_QUAN}" change="valqty" maxLength="13" />
</cells>
</ColumnListItem>
</items>
</Table>
Thanks

Thanks Robin,
But in my case oEvent.getSource() is returning the cell instance and
oEvent.getSource().getBindingContext() is undefined
Hence not getting the value
I also tried the following
oEvent.getSource().getParent().getParent().indexOfItem()
But index returned is -1
