How to catch IE7 tab change event in Java Applet?

My applet have some modeless dialogs, When I start my applet with modeless dialog in tab1, if I swith to tab2, the modeless dialog of tab1 remains open.
So I want to catch the tab change event, and set modeless dialog invisible when tab changes.
Who knows the solutions.... Thanks

To get to the IE7 browser, you'll have to go through JNI if you're using Java to get to a C level interface. You'll have to write the code to interface to it also. IE7 does not have a Java interface, inface, MS has a vested interest in not supporting a Java interface. You'll have to look up the IE7 developers docs to see the OLE interface you'll have to hit.

  • How to handle tab change event in UI shell main area

    Hi,
    I have two tabs(two taskflows) in UI shell main area. one is department tab and another is employee tab. My department tab shows employees department wise. On employee tab I have emplyee table which shows employees jobwise. This employee table has the functionality of adding new record to employee vo as well.
    Now i follow these steps.
    1. by defualt department tab is open.
    2. by clickinng on Tasks menu link i open Employee tab in to main area. Now i have both tabs in main area.
    3. at Employee tab I search all employees job = accountant. It shows the search result well.
    4. Now i add a new record to it and without saving/deleting this record i move to department tab.
    5. at Department tab i search employees where department =20, here no relation b/w job and department.
    6. Now i return to employee tab. my newly added record got disappeared. It is there but does not show in table.
    How to resolve it??
    I have one solution in my mind while changing the tab i can prompt to user "you can not leave the newly added record..either save it or delete it". But how to catch tab change event here? where i can write code to prompt msg to user?
    Pls help.

    With apologies for the slow reply, I'm currently travelling.
    Two things to note:
    1) The af:document uncommittedDataWarning flag was designed to stop users navigating away from half entered records. More about this flag can be found here:
    http://docs.oracle.com/cd/E23943_01/web.1111/b31973/af_orgpage.htm#CACDDDFH (see point 4)
    http://www.oracle.com/technetwork/developer-tools/adf/unsaveddatawarning-096556.html
    ....please note our documentation from time to time spells this flag wrong with only one "t" in the word committed, so if you're attempting a bulk search check for this (and I'll raise document bugs to get this fixed in the future).
    2) On addressing the ADF UI Shell, if you're switching between "pages" in the UI Shell, as separate to switching between dynamic tabs within a single page using the UI Shell, the UI Shell will actually restart the currently running task flow in the page you're returning too. You can verify this by implementing an initializer on your task flow with a log message, and watching when the initializer is called.
    In addressing your last question, at this stage I think you need to assess my first answer then come back if you think you sill need to execute the code on the tab click. I also need to know are you talking about the primary level of tabs that represent each page in the UI Shell, or are you referring to the dynamic tabs within a single UI Shell page that hold your task flows?

  • Tab Change Event

    Hi Experts
    I  am having problem for catching System (SAP ) Tab Change Event in AP Invoice
    In Ap Invoice in Accounting Tab in Jounal Remark Field .I have change text but When i Click following tab text changes automatically I am doing this by addon

    Hello
    You can connect you FMS into the document status/document total/ Create date fields (select from the list), and not to the Customer when it is entered.
    By this when you post the document, these fields are calculated / validated that time, so the fms will be called as the last step. int this way disabling the tab change is not necessary.

  • How to catch cell lost focuse event of matrix

    Dear all
    can you tell me how to catch the cell lost fouc event of matrix.
    i want to check the value is entered the that cell, which is not greter than the extising value..
    thanks in advance......

    Hi
    For that you can use either validate or lost focus event
    Private Sub SBO_Application_ItemEvent(ByVal FormUID As String, ByRef pVal As SAPbouiCOM.ItemEvent, ByRef BubbleEvent As Boolean) Handles SBO_Application.ItemEvent
            ' BubbleEvent sets the behavior of SAP Business One.
            ' False means that the application will not continue processing this event.
            ' Validate event
            If (pVal.FormType = 133) And (pVal.ItemUID = 38) And (pVal.ColUID = 1) And _
              (pVal.EventType = SAPbouiCOM.BoEventTypes.et_VALIDATE) Then
                If (pVal.Before_Action) Then
                    'write your code
                End If
            End If
            'Lost focus event
            If (pVal.FormType = 133) And (pVal.ItemUID = 38) And (pVal.ColUID = 1) And _
             (pVal.EventType = SAPbouiCOM.BoEventTypes.et_LOST_FOCUS) Then
                If (pVal.Before_Action) Then
                    'write your code
                End If
            End If
        End Sub
    Hope this helps

  • How to catching Clear-Sort button event?

    Does any one know how to catch the event when user click the Clear-ALL-Sort button? I would like to do somthing in Java by catching this event.
    thanks in advance.
    John

    I'm not really sure what you mean.
    LIke, I want to use the three event listener functions like a global or static function for all of the buttons which I think I've done for the most part.
    However, I'm having an issue with the current state of the button. Like...
    1 - on
    2 - off
    3 - off
    4 - off
    1 - off
    2 - on
    3 - off
    4 - off
    1 - off
    2 - off
    3 - on
    4 - off
    1 - off
    2 - off
    3 - off
    4 - on
    Really redundant right? So I want to beable to pass something through the event listener functions somehow so I only have to right the listener section once instead of 4 times.
    Know what I mean? If I was in an external document class structure I could just re-create my own event listener class to pass aonther property/parameter. But I don't know what I can do within AS3 internally in the Flash movie to do this.
    Just seems likes there should be a relatively simple way to do this, but I'm not sure how many errors I'd have to wade through or if it's even possible.

  • Catching the Record Change Event

    Hello,
    We are currently using SAP 2004, and would like to catch an event when a sap record changes, for example in Item Master Data window when the user clicks on the << < > >> and the Item Number/ Information changes. From what I can tell there is no specific form event that can be caught like on item number text change…
    Any help with this problem would be greatly appreciated
    Thanks

    Hi Bill,
    Unfortunately, there is not a "record change".
    You'll have to catch all the menu event when the user click on the << < > >>
    Private Sub SBO_Application_MenuEvent(pVal As SAPbouiCOM.IMenuEvent, BubbleEvent As Boolean)
          If pVal.BeforeAction = False Then
              Select Case pVal.MenuUID
                Case "1288" 'Next Record
                    oRecordSet.MoveNext
                    '// If reached EOF show last
                    If oRecordSet.EOF = True Then
                        oRecordSet.MoveLast
                    End If
                Case "1289" 'Previous record
                Case "1290" 'First record
                Case "1291" 'Last record
                End Select
            End If
    End Sub

    Hi,
    As per the link you gave,
    In the View layout, You can use the UI elements like - AcfExecute and AcfUpDownload. For upload and download the things.
    Try to use these UI elements and get the reference of the Abrstact APplet class and use the methods inside it.

  • How can I fire a change event from a JComboBox and JTextField?

    Is it possible to fire a ChangeEvent from JComboBox?
    Is it possible to fire a ChangeEvent from JTextField?
    If so how can I do that? Thanks.

    You can use an ItemStateListener with the combobox
    As for the textfield, it depends when you want to catch events (every keystroke, or when the user hits enter) but either way, you can do this too. Check keylistener and actionlistener
