JChecjBox and JTextField Event Handling in JTable

Hi,
I am creating a dynamic Jtable from data in Database. My table has x num of rows and 5 cols. I have 2 editable columns in Table. one is of type checkbox and other is textfield. I have also created a CustomTableModel which extends DefaultTableModel. My Question is How to trap an even on JCheckBox and JTextField when User changes the data in the table. I want trap the event, read the new data and save it to the database.
Please help me with this problem.
I am fairly new at JTable..Please help me. Do i need to create customeCellEditor??
Thank you.

Thank you for your help. From TableChanged event I can find out that table has been updated. But how do i know which rows were updated? I mean How do i know which checkbox was checked/unchecked, or JTextfield text was changed? I need to read them one by one and compare with previous data. TO do that Do i need customCellEditor? Editable Checkbox is in first col of table and Editable Jtextfield is in 4th col. Number of rows vary depending on my resultset from DB.
Please help me.
Thank you in Advance.

  • How to add event handler to JTable?

    I need an event listener that tells me whenever a cell has been edited. Does anyone have any ideas on how to implement this. There doesn't seem to be much documentation on the subject.
    Thanks in advance..

    Hello,
    It looks like you are interested in the
    BeforeAttachmentAdd event of Outlook items. It is fired before an attachment is added to an instance of the parent object. So, you can analyze the attachment object passed as a parameter and set then Cancel argument - set
    it to true to cancel the operation; otherwise, set to false to allow the Attachment to
    be added.
    Also the Outlook object model provides the
    AttachmentAdd event for Outlook items. It is fired when an attachment has been added to an instance of the parent object. You can also analyze the attachment object passed as a parameter to the event handler. You will not be able to
    cancel the action in that case.

  • Multiple movieclips and mutiple event handling.

    Hi All,
    I have multiple movieclips(images sequence), which I want to add mouseevent (click and drag), keyboard event(left and right arrows) and zoom event(mouse wheel).
    I have this function for only one mc(one image sequence).
    Now if I use this function, I am having problem with calling the function from the same frame.
    That is,
    If click another mc from say frame 3, and click on another function, it should continue from frame 3 only, not start from first frame again.
    Please help.
    Thanks in advance.

    I assume that shows the part where you rotete the house view in a 360degree fashion?
    if so, make a global var on your root timeline:
    var rotationframe:int = 1; //in the beginning of the app all the dirffernt images are sitting on frame 1
    you can access this var from anywehere inside any function of your app by calling:
    root.rotationframe
    now in the function that handles the rotation (lets say its your keyboard function) in the end (after you moved the playhead) you make sure to always set
    root.rotationframe  =  garage.currentFrame;
    and in the function that handles the switching between images you write sth. like
    gotoAndStop(root.rotationframe);
    Be aware, you can`t simply use that code without adapting it to your special needs.

  • How to get selection of a DropdownListBox and its event handler

  • Related JtextField Event Handling

    Hi,
    In the JtextField whener I pressed the ALT + TAB the focus lost of the
    JtexrField is called.After that again pressed the Tab in the same Jtextfield the KeyListener is not fired.Is there any possibility to fire the
    Event whener we pressed the Tab second time.
    Regards,
    Naresh.

    So, you press ALT+TAB in a JTextField and it loses focus.
    Do you give focus back to the JTextField before you press Tab again? That
    could be one problem. The second is that Tab is a focus traversal key, and
    so the focus manager is going to process that key before the component
    sees it. You could remove Tab as a focus traversal key, and that would allow
    the component to receive it, but I'm not sure you want to do that.

  • Event Handling in JTable Custom Cell Renderer

    I have a JLabel as a custom cell Renderer for a column. I want to handle mouse click event for the JLabel rendered in the cell.
    I tried adding the listener for the label in the custom cell renderer but it is not working. Any ideas how to handle this problem??
    Thanks

    If you want to handle the selection of a tree node
    1) write a class like:
    public class TreePaneListener implements TreeSelectionListener {
    // TREE SELECTION LISTENER
    public void valueChanged(TreeSelectionEvent e) {
    JTree tree = (JTree)e.getSource();
    DefaultMutableTreeNode node = null;
    int count = 0;
    boolean doSomething = false;
    if(tree.getSelectionCount() > 1) {
         TreePath[] selection = tree.getSelectionPaths();
         int[] temp = new int[selection.length];
         for(int i =0; i < selection.length; i++) {
    // Check each node for selection
         node = (DefaultMutableTreeNode)selection.getLastPathComponent();
         if(node.getLevel()==2) {
    // Change this code to take the action desired
         doSomething = true;
    2) After creating the tree register the listener
    TreePaneListener handler = new TreePaneListener();
    tree.addTreeSelectionListener(handler);

  • Event handler eats up memory. Bad programing and/or bug.

    Hello
    I've been programming a GUI for a project. The basics of the program is a sample routine that updates a array once a second. Once the array is updated I use a event handler to plot the new array in a graph.
    When I wrote this gui I think I've stumbled upon a bug in Labviews memory allocation.
    If you have two loops. One that builds a array and then signals a loop with a eventhandler that reads the array and the event handler is stoped for a few seconds (by opening a sub vi or something inside the event handler), the memory goes berserk. When the event handler is free after the stop the memory is still allocated and does not return.
    I could not find any information on this problem in the forum so I thought I would share this information with everyone. I managed to reproduce this phenomena in a small example (attached), if anyone is interested in it. The problem is simple to fix once you recognize the problem. However it was not the simplest problem to find (imho that is ).

    Where are you seeing the memory being allocated? What tool are you using, task manager or LabVIEW profiling? I'm not seeing what you describe (LV 7.1.1 on a 3.4 GHz Pentium 4 w/ 1 Gb memory)

  • Help needed in implementing validation event handler in OIM 11g

    I have implemented preprocess and postprocess event handler before with similar kind of plugin registration, metadata import and everything worked fine. Not sure what is the problem here with validation event handler.
    Thanks

    Instead of registering the plug-in can u try placing it in the plugins folder under Oracle_IDM1/server folder.
    at times restart is required. esp when the server is running in production mode.

  • Event Handling in Fullscreen Exclusive Mode???????

    WIndows XP SP2
    ATI 8500 All-In-Wonder
    JDK 1.6
    800x600 32dpi 200 refresh
    1-6 buffer strategy.
    the graphic rendering thread DOESN'T sleep.
    Here's my problem. I have a bad trade off. In fullscreen exclusive mode my animation runs <30 fps and jerks when rendering. i.e. stop and go movement (not flickering/jittering just hesitant motion) when the animation is running. I solved this problem by raising the thread priority of the rendering (7-8). . . this resulted in latency/no activity for my input events both key and mouse. For instance closing the program alt-f4 will arbitrarily fail or be successful when the thread priority is raised above 6.
    How does one accomplish a >30 fps and Instant event handling simultaneously in Fullscreen Exclusive Mode?
    Is there a way to raise thread priority for event handling?
    Ultimately I want to be able to perform my animations and handle key and mouse input events without having a visible 'hiccups' on the screen.
    Much Appreciated!

    If I remember correctly the processor is a 1.4(or)6ghz AMD Duron
    Total = 1048048kb
    Available = 106084kb
    Sys Cache = 211788kb
    PF Usage = 1.01 GB
    I solved some of the problem after posting this thread. . . .
    I inserted a thread.sleep(1) and my alt-f4 operation worked unhindered with the elevated thread priority.
    I haven't tested it with mouse event or any other key event but at the moment it looks I may have solved the problem.
    If so, my next question will be is there a way to reduce the amount of cpu power needed to run the program.
    I'm afraid that the other classes that I'm adding will actually become even more process consuming than the actually rendering thread.

  • Shared Variable event handling--spurious events

    This is more of a nuisance than anything:
    Using the DSC module to register for shared variable events, the event structure always fires once for each variable registered for. For example, if I register for the shared variables "Var1" and "Var2", upon entering the event structure [in a loop], I'll immediately see two events [one for Var1 and one for Var2] even if the values for Var1 and Var2 haven't changed.
    I originally figured that it's intentional--it appears to be impossible to use SV events without this "feature"--except it doesn't happen in "highlight execution" mode, which I find puzzling.
    Why does this exist, and is there some magic way to disable it? Or is it a bug? Anybody who has ever used SV events undoubtedly has some way of dealing with this. Right now I just burn off the first N events, where N is the number of shared variables I'm registered for. But that's extra diagram junk and it really shouldn't be necessary.
    Solved!
    Go to Solution.

    Kyle:
    Here's a sample project with two SVs and an event handler VI. SV1 has an initial value but SV2 doesn't.The array displayed in the front panel should be empty after running--the SV's are not written to anywhere. I get two entires--one from each event--when I run the VI.
    I noticed some new behavior when I put this together. In this example I use the timeout condition to terminate the loop. There is a timeout value around 110ms that defines the cutoff for this behavior--but the value is not consistent. With timeout values ~110 and below, I get no spurious events. But I DO get them for any timeout value of above that. So perhaps this issue is invisible to anybody who is generating events faster than ~10Hz. This may explain why I've been having inconsistent behavior when using the execution trace.

  • Convert onEnterFrame Event Handler  AS2 code into AS3

    My code of AS2 is given below. I do not know what event handler type is used and which event handler is used in AS3.
    onEnterFrame = function(){

    this.addEventListener(Event.ENTER_FRAME,onEf);
    // "this" references the movie itself, you can also use "stage" or the instance name of an object on the stage
    // look up addEventListener in the online help. This method takes two arguments, the event that you want to "listen" for and the name of the function to execute when the event occurs.
    // the function that will be called when the event occurs. It takes one argument that corresponds with the first argument of the addEventListener method.

  • Cant add Rows In a Matrix (Child) and No event catching

    Hi,
    I created a Master File and its Child. Registered as an UDO. Created an UDO Form with the UDO Form Generator.
    I Can Add, find, update, records to de Master File, but The Matrix related to the Child Table Only allows me enter information in the first Row.
    I Have tried the addrow command in every place possible, but It doesnt work.
            Dim oXmlDoc As Xml.XmlDocument
            oXmlDoc = New Xml.XmlDocument
            Dim sPath As String
            sPath = IO.Directory.GetParent(Application.StartupPath).ToString
            oXmlDoc.Load(sPath & "" & FileName)
            SBO_Application.LoadBatchActions(oXmlDoc.InnerXml)
            oForm = SBO_Application.Forms.Item("F_MX_C071")
    The last thing I tried was include this next lines after
            oItem = oForm.Items.Item("mtx_0")
            oMatrix = oItem.Specific
            oMatrix.AddRow(3)
    I Also Cant catch the AddRow Event Button. I Set the filters and the event handling for menus and
            oFilters = New SAPbouiCOM.EventFilters
            oFilter = oFilters.Add(SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED)
            oFilter.AddEx("F_MX_C071")
            SBO_Application.SetFilter(oFilters)
    If (pVal.EventType = SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED) Then
    Events are catched before oForm = SBO_Application.Forms.Item("F_MX_C071"). After that, there´s no event catching
    Can anyone help me? I have a lot of time spent in this issue.
    Thanks a lot.

    I dont know if Is it clera for me now, but i try it.
    You have matrix on user form. The matrix contains child data. This child data are inserted to matrix manualy or bounded to some datatable, i think with datatable?
    When you add new line to matrix, Im using
    omatrix.AddRow(1, 0) - 1 is that I want to add 1 row, 0 is position, where the new line will be in matrix
    When the matrix is filled with code, Im doing it as
    I update usertable
    oUserTable.UserFields.Fields.Item("U_Popis").Value = ""
    oUserTable.UserFields.Fields.Item("U_PATH").Value = ed.String
    then update the form to affect changes to db
    oOrderForm.Update()
    and then I make new bounding to datatable.
    Undestand I correctly it now?

  • About CL_GUI_ALV_GRID's event-handling & PAI/PBO

    Hi, all,
    I met a problem when using CL_GUI_ALV_GRID's event-handling.
    I created a simple event-handling-class with an event-handling-method for DOUBLE-CLICK event of CL_GUI_ALV_GRID. And the event-handling-method, only makes some changes to the contents of itab to be shown in ALV_GRID.
    The problem is: In my idea, after event-dispatch and event-handling in PAI, subsequent PBO will be called. Since SET_TABLE_FOR_FIRST_DISPLAY is called in PBO, I would saw the changed itab shown. BUT, I saw the contents of the itab remaining unchanged.
    * PAI module, DISPATCH the event
      CASE OK_CODE.
        WHEN OTHERS.
          CALL METHOD cl_gui_cfw=>dispatch.
      ENDCASE.
    I debugged, and found that, after event-handling-method, PBO module doesn't execute.
    That's my wondering, after the preceding PAI, shouldn't the subsequent PBO appear? OR is event-handling different from other user actions?
    Many thanks.

    Hi,
    for double click you need explicit handler ,
    just check it.

  • 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.

    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
