Getting the value of a checkbox in an item renderer?

I have a list that uses an item renderer with buttons and data.  I need to add a checkbox and get the value of this checkbox passed along with the event of the pushbutton.
When the user clicks "add to menu: there is a click handler:
protected function addButton_clickHandler(event:MouseEvent):void
                    doubleIt = double.selected;
                    owner.dispatchEvent(new Event("ADD_TO_MENU", true));
Back in the main application, there is a listener for this event.  I want that handler to be able to "know" the status of that checkbox (i.e. the value of "doubleIt", defined as a public boolean).
private function addToMenuHandler(event:Event):void {
           var i:int = event.target.selectedIndex;
           var obj:Object = new Object();
           obj = recipeListCollection.getItemAt(i);
           menuList += obj;
I have tried various permutations of the event.target, but can't figure out how to access that variable.

Create a custom event and stuff anything you want in there.

  • How can I get the value before a checkbox if it's selected

    Please refer the below screenshot. I want to get the values before a checkbox if the checkbox is slected. And I want to add those values. How can I do this?
    So according to the screenshot, I want to take 1500+1500+1000 value. Can I achieve this?
    +100

    Hi phantom,
    Row 1 is a Header Row. Row 10 is a Footer Row.
    Formula in Footer Cell B10
    =SUMIF(C,TRUE,B).
    SUMIF will sum the values in B where there is a tick (TRUE) in C.

  • How to get the value from the checkbox

    Hi All,
    Good Evening,
    i want to get the value from the check box.
    for this i wrote like this
    OAMessageCheckBoxBean cbb=(OAMessageCheckBoxBean)webBEan.findChildRecurssive("item240")
    String val=cbb.getvalue(pageContext).toString();
    val getting the value only when checkbox is checked.
    suppose check box is not checked that time i got NULL POINTER exceptionn.
    so
    i tried the following way alsoo
    string val=pageContext.getParameter("item240");
    here val return 'on' only when checkbox is checked.
    otherwise NULL value returnss.
    but i want to get the value is 'Y' when i am checked the checkbox
    otherwise returns NULL valuee.
    already i set the checkbox properties alsoo
    Checked :Y
    unchecked:N
    pls tell me

    Hi,
    use
    try
    OAMessageCheckBoxBean cbb=(OAMessageCheckBoxBean)webBEan.findChildRecurssive("item240")
    String test = cbb.getvalue(pageContext).toString();
    catch(Exception e)

  • Getting the Values from a Tiled View

    Hi,
    I have a TiledView and I have checkbox in the tiled view. I am trying
    to get the values of the checked boxes.
    I have coded like this.
    Object[] links = getRSystemLinks().getCbSystemUrl().getValues();
    if I see the links.length i get only one. In html If I see the code
    it appends the TileIndex in brackets. If I replace the TileIndex with
    0 in all the fields in endCbSystemUrl method I get the correct values.
    In the TiledView beginDisplay() method my code is like this.
    if (getPrimaryModel() == null) throw new ModelControlException
    ("Primary model is null");
    super.beginDisplay();
    resetTileIndex();
    pgCustomizeLinksViewBean parentBean = (pgCustomizeLinksViewBean)
    getParent();
    ((DatasetModel) getDefaultModel()).setSize
    (parentBean.SystemChoicesValue.size());
    Any Suggestions on this.
    Thanks
    Namburi

    Namburi--
    Remember, the getValues() method does not return the values from a column in
    a TiledView. It is strictly for use by fields that can have multiple
    values, like multi-select list boxes.
    DO NOT remove the indexing feature from the field names, especially in the
    case of checkboxes, because checkboxes aren't submitted back to the server
    unless they are checked. By overriding the automatic checkbox tracking
    feature JATO provides, you won't be able to tell which checkboxes were
    actually checked by row--you'll simply get back a list the same size as the
    number of checkboxes that were checked, without any placeholders for the
    ones that weren't checked.
    Instead, on submit, you simply need to move through the tiledView and check
    the value of checkbox on each row:
    tiledView.beforeFirst();
    while (tiledView.next())
    if (getDisplayFieldBooleanValue("myCheckBox"))
    You can use the same construct to build up an array or list:
    List checkedList=new LinkedList();
    tiledView.beforeFirst();
    while (tiledView.next())
    if (getDisplayFieldBooleanValue("myCheckBox"))
    checkedList.add(new Boolean(true))
    else
    checkedList.add(new Boolean(false))

  • How to get the values of a selectManyCheckBox when that is in h:dataTable

    Hello,
    I have a jsp page. in that user can choose multile checkboxes and these checkboxes labled as Current, Mailing, PosibleMailing, length is 3 fixed.
    And i am displaying this in a <h:dataTable> this datatable length depends upon the users there may be more than 1 user, for every user there is multiplecheckbox with length 3(fixed).
    code is look like this
    <h:dataTable value="#{InvestigationDefendantView.investDefsFindingsModel}" var="def" border="0" >
    <h:column>
    <h:selectManyCheckbox value="#{InvestigationDefendantView.addtype1}" disabled="false">
    <f:selectItem itemValue="Current" itemLabel="Current"/>
    <f:selectItem itemValue="Mailing" itemLabel="Mailing"/>
    <f:selectItem itemValue="Posible" itemLabel="Posible"/>
    <j4j:idProxy id="DefAddTypeProxy"/>
    </h:selectManyCheckbox>
    </h:column>
    </h:dataTable>
    here abovevalue="#{InvestigationDefendantView.investDefsFindingsModel}" suppose 3(we can assume) then there are 3 pairs of selectManyCheckBoxes are there in my jsp page.
    So u can assume in my jsp page checkboxes are look like 3*3 Matrix
    from my backing bean i am fetching the values of this checkboxes with the below code
    java code:
    InvestDefAddressTypeGetter inv = new InvestDefAddressTypeGetter();
    InvestDefAddressTypeBean[] inb = inv.get(pID);
    this.fMap = new HashMap<String, ArrayList<String>>();
    for(int i=0; i<inb.length; i++)
    String str1 = inb.getGivenDefID().toString();
    this.fdefid.add(str1);
    this.fGivenDefID.add(inb[i].getGivenDefID());
    String addType = inb[i].getAddType();
    Logger.info(this, "adding type value", addType);
    this.fdefid.add(str1);
    this.faddType.add(addType);
    Logger.info(this, "length of strings", this.faddType);
    this.fMap.put(str1, this.faddType);
    i am fetching the checkboxes value through my get method
    public String[] getAddtype1() throws SQLException, SearchException
    Logger.info(this, "addtype testing", this.faddType.size());
    if (this.faddType.size() > 0 )
    ArrayList<String> alcb = new ArrayList<String>();
    for (int i = 0; i < this.faddType.size(); i++)
    alcb.add(this.faddType.get(i));
    String[] tempArr = new String[alcb.size()];
    for (int i = 0; i < alcb.size(); i++)
    tempArr[i] = alcb.get(i).intern();
    return tempArr;
    return new String[0];
    from the above code if i have clicked (you can assume 3*3 matrix here) 1*1, 1*2 and 2*1 and 2*2and saving the value in database records are saved as per requirement but when i am editing the records with the above code i am getting 1*1, 1*2 and 2*1, 2*2 and 3*1, 3*2 checked but i did not checked the 3*1 and 3*2 ckeck boxes.
    Because the same get method will be called in the multipleckeck boxes. how can i prevent does not display the unchecked value from my backing bean.
    Please anybody help me in this issue.

  • How to get the values from popup window to mainwindow

    HI all,
       I want to get the details from popup window.
          i have three input fields and one search button in my main window. when i click search button it should display popup window.whenever i click on selected row of the popup window table ,values should be visible in my main window input fields.(normal tables)
       now i am able to display popup window with values.How to get the values from popup window now.
       I can anybody explain me clearly.
    Thanks&Regards
    kranthi

    Hi Kranthi,
    Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

  • Get the value from a selected row in a table

    Hi all,
    My table contains a tree structure.
    When I select a single row, I need to get the value of a particular column.
    I created an action on the leadSelect of the table and gave the following code:
    public void onActionleadValue(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
        //@@begin onActionleadValue(ServerEvent)
        String strLeadValue = wdContext.nodeAttribute_View_Out().currentAttribute_View_OutElement().getAttributeAsText("<MyModelAttributename>");
        wdComponentAPI.getMessageManager().reportSuccess("selected lead value "+strLeadValue);
        wdContext.currentContextElement().setLeadselectedvalue(strLeadValue);
        //@@end
    My Bapi returns me 6 records. and when I click on any row its always pointing to the last record value.
    What could be the problem?
    Thanks

  • Having problem to get the value from radio button

    i am doing my double module project for my degree course and i am also a newbie in JSP. Hope there is someone can help me to solve this problem. Now, i set the value of a radio button to "don't smoke", "smoke lightly", and "smoke heavily". Then i use request.getParameter ("smoking behavior") to get the value selected by the user, but the result is only "don't" or "smoke", which the character after spacing will be not be retrieved. I dun know how to solve it, so can any expert here help me to solve this problem? Thanks for helping.

    Why do you have to use whitespace. If your radio button group is name smokingBehavior - no whitespace, wouldn't it just make sence to have values of don't, lightly and heavily. This would solve the problem easily. If your teacher is being a pain in the a&!, and requires you to use whitespace for your naming variables I guess you could insert %20 between the two words and unescape the value on the server side. This seems like a lot of unnecessary work and a silly solution - good luck!

  • NullPointerException - Cannot get the value from variable f_cashGiven

    In SubCheckout.java (a POS), what I want is when Payment button (f_cashPayment) is pressed, the action "Cash" is performed, get the value from Cash Given (f_cashGiven), do the subtraction and post the value as Cash Return (f_cashReturn).

This should be quite straight forward, but I do not know what is wrong. Please help!

    If getValue() returns null, you need to trace the execution of the code and figure out which sequence of code is leading to the return of null. This method looks complex - a lot of if statements. If you do not have a debugger, put System.out.println statements inside the method to figure out what's going on.

  • Cannot get the value after space

    i am doing my double module project for my degree course and i am also a newbie in JSP. Hope there is someone can help me to solve this problem. Now, i set the value of a radio button to "don't smoke", "smoke lightly", and "smoke heavily". Then i use request.getParameter ("smoking behavior") to get the value selected by the user, but the result is only "don't" or "smoke", which the character after spacing will be not be retrieved. I dun know how to solve it, so can any expert here help me to solve this problem? Thanks for helping.

    You can't use spaces in passed parameters; either give your options numerical values that you can translate on the receiving end, or do an URLEncoder.encode() on the values before submitting them. If you encode them, you'll do an URLDecoder.decode() on them on the receiving end.
    URLEncoder.encode("don't smoke") = "don%27+smoke"
    URLDecoder.decode("don%27+smoke") = "don't smoke"

  • Swing: when trying to get the values from a JTable inside an event handler

    Hi,
    I am trying to write a graphical interface to compute the Gauss Elimination procedure for solving linear systems. The class for computing the output of a linear system already works fine on console mode, but I am fighting a little bit to make it work with Swing.
    I put two buttons (plus labels) and a JTextField . The buttons have the following role:
    One of them gets the value from the JTextField and it will be used to the system dimension. The other should compute the solution. I also added a JTable so that the user can type the values in the screen.
    So whenever the user hits the button Dimensiona the program should retrieve the values from the table cells and pass them to a 2D Array. However, the program throws a NullPointerException when I try to
    do it. I have put the code for copying this Matrix inside a method and I call it from the inner class event handler.
    I would thank you very much for the help.

    here goes the code:
    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
    import AdvanceMath.*;
    public class MathF2 extends JFrame {
    private JTextField ArrayOfFields[];
    private JTextField DimOfSis;
    private JButton Calcular;
    private JButton Ativar;
    private JLabel label1;
    private JLabel label2;
    private Container container;
    private int value;
    private JTable DataTable;
    private double[][] A;
    private double[] B;
    private boolean dimensionado = false;
    private boolean podecalc = false;
    public MathF2 (){
    super("Math Calcs");
    Container container = getContentPane();
    container.setLayout( new FlowLayout(FlowLayout.CENTER) );
    Calcular = new JButton("Resolver");
    Calcular.setEnabled(false);
    Ativar = new JButton("Dimensionar");
    label1 = new JLabel("Clique no bot�o para resolver o sistema.");
    label2 = new JLabel("Qual a ordem do sistema?");
    DimOfSis = new JTextField(4);
    DimOfSis.setText("0");
    JTable DataTable = new JTable(10,10);
    container.add(label2);
    container.add(DimOfSis);
    container.add(Ativar);
    container.add(label1);
    container.add(Calcular);
    container.add(DataTable);
    for ( int i = 0; i < 10 ; i ++ ){
    for ( int j = 0 ; j < 10 ; j++) {
    DataTable.setValueAt("0",i,j);
    myHandler handler = new myHandler();
    Calcular.addActionListener(handler);
    Ativar.addActionListener(handler);
    setSize( 500 , 500 );
    setVisible( true );
    public static void main ( String args[] ){
    MathF2 application = new MathF2();
    application.addWindowListener(
    new WindowAdapter(){
    public void windowClosing (WindowEvent event)
    System.exit( 0 );
    private class myHandler implements ActionListener {
    public void actionPerformed ( ActionEvent event ){
    if ( event.getSource()== Calcular ) {
    if ( event.getSource()== Ativar ) {
    //dimensiona a Matriz A
    if (dimensionado == false) {
    if (DimOfSis.getText()=="0") {
    value = 2;
    } else {
    value = Integer.parseInt(DimOfSis.getText());
    dimensionado = true;
    Ativar.setEnabled(false);
    System.out.println(value);
    } else {
    Ativar.setEnabled(false);
    Calcular.setEnabled(true);
    podecalc = true;
    try {
    InitValores( DataTable, value );
    } catch (Exception e) {
    System.out.println("Erro ao criar matriz" + e );
    private class myHandler2 implements ItemListener {
    public void itemStateChanged( ItemEvent event ){
    private void InitValores( JTable table, int n ) {
    A = new double[n][n];
    B = new double[n];
    javax.swing.table.TableModel model = table.getModel();
    for ( int i = 0 ; i < n ; i++ ){
    for (int j = 0 ; j < n ; j++ ){
    Object temp1 = model.getValueAt(i,j);
    String temp2 = String.valueOf(temp1);
    A[i][j] = Double.parseDouble(temp2);

    What I did is set up a :
    // This code will setup a listener for the table to handle a selection
    players.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
    ListSelectionModel rowSM = players.getSelectionModel();
    rowSM.addListSelectionListener(new Delete_Player_row_Selection(this));
    //Class will take the event and call a method inside the Delete_Player object.
    class Delete_Player_row_Selection
    implements javax.swing.event.ListSelectionListener
    Delete_Player adaptee;
    Delete_Player_row_Selection (Delete_Player temp)
    adaptee = temp;
    public void valueChanged (ListSelectionEvent listSelectionEvent)
    adaptee.row_Selection(listSelectionEvent);
    in the row_Selection function
    if(ex.getValueIsAdjusting()) //To remove double selection
    return;
    ListSelectionModel lsm = (ListSelectionModel) ex.getSource();
    if(lsm.isSelectionEmpty())
    System.out.println("EMtpy");
    else
    int selected_row = lsm.getMinSelectionIndex();
    ResultSetTableModel model = (ResultSetTableModel) players.getModel();
    String name = (String) model.getValueAt(selected_row, 1);
    Integer id = (Integer) model.getValueAt(selected_row, 3);
    This is how I got info out of a table when the user selected it

  • All I want to do is get the value associated..

    All I want to do is get the value associated with a dropdown item...
    1. I have a combo box
    2. It has text values that you can click
    3. The text values have export values associated with it
    4. When I click a text value from the list, I want to get the numeric value associated with it
    Example combo box:
    "Orange" has the export value of "1234"
    When I click "orange" I want to get the export value "1234" and alert it to the screen
    I'm using javascript, here's what I have so far:
    In the combo box properties I have the following validation script:
    theFruitClicked();
    I have a function in the document javascript:
    function theFruitClicked()
         app.alert(event.value);
    This is alerting the text value not the export value.
    What else should I do to get the export value?
    Thank You.
