Passing data from a jFrame to another during runtime

Hi,
I have a JFrame which has a JTable and a button. I want when the user presses the button a new JFrame to open which has some fields that could be filled and after the user fills the fields those infos to be displayed in the first frame in JTable.
How could this be done?
Help is appreciated

Thanks for the reply ..
What I have tried to do is:
I Created a file called eventl10.java which has a constructor that recieves a object of type stdman (which in this case is the frame which contains the table) .. in the same time I have made another constructor which recieves a object of type addgrd as an argument (the frame for inserting the infos) and tried to somehow make a "connection" between these two which seems to throw a NullPointerException. So obivously this is not the way to be done:
package gui;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class eventl10 implements ActionListener {
     stdman obj;
     addgrd obj2;
     public eventl10 (stdman app)
          obj = app;
     public eventl10 (addgrd app)
          obj2 = app;
     public void actionPerformed(ActionEvent e) {
          if (e.getSource() == obj2.jButton3)
               obj.addr_b.setText("Test");
}I just want some tips how could I set the text of a JTextField (which is found in another JFrame running at the moment).
Thanks for your replies

  • Passing data from a container to another

    Hi,
    Let's say I have two containers (Container1=application , Container2).  Container1 gets some data from user, perform some database lookup and displays Container2 with the results from database lookup.
    Container1 --(call and display)--> Container2
    Below shows  how I am using a bindable variable in Container1 to pass the data from Container1 to Container2.  Also shows how I display Container2 from Container1.
    <!-- Container1 -->
    <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
       [Bindable] public var foo:String = "bar";
       private function loginHandler(event:LoginEvent):void
          mycontainer2 = new Container2();
          mycontainer2.name = "mycontainer2";
          this.addChild(mycontainer2);
    </mx:Application>
    I am accessing the data in Container2 as follow:
    <!-- Container2 -->
    {mx.core.Application.application.foo}
    Q1) Is there a better way to pass data from one container to another and access the data?
    Q2) Is this the only way to call and display Container2 from Container1?
    Q3) How can I move back to Container1 from Container2, i.e. Container2 call and display Container1
           Container2 --(back to)--> Container1

    Best practices call for using custom events to share data between components. Here is my Flex 3 Cookbook post on the topic:
    http://cookbooks.adobe.com/index.cfm?event=showdetails&postId=15466
    To switch easily between containers 1 & 2 use a ViewStack, the gold standard for such interaction, and manipulate the selectedIndex or selectedChild property:

  • Problem in passing data from 1 screen to another using BBP_DOC_CHANGE_BADI.

    Hi Experts,
    i am new to the SRM, i am facing problem in passing data from one screen to another.
    my requirement is that when we select one shopping cart and press the PROPOSE SOURCES OF SUPPLY button, we will fetch all the contracts that are attached to the shopping cart.
    we have implemented a BADI implementation of BBP_SOS_BADI (method BBP_SOS_CHECK) for passing some changed values to the contracts of the shopping cart into the popup screen that is displayed when we press PROPOSE SOURCES OF SUPPLY button and when we select any contract and press ASSIGN ONLY button in the popup screen the badi BBP_DOC_CHANGE_BADI is triggered.
    i have implemented another BADI implementation of BBP_DOC_CHANGE_BADI for fetching the selected contract and pass the values to another screen, but the problem is that when we select one contract and press the assign only button we are fetching the wrong contract number ( that is in the BADI method BB_SC_CHANGE parameter IT_ITEM we are fetching the wrong contract), if we again do the same procedure for the second time we are getting the correct contract.
    i am unable to understand why we are getting the wrong contract in the first time( that is we are getting contract other than the selected one).
    as per my understanding i think when we are passing data to the popup screen using BBP_DOC_CHANGE_BADI we are not updating the shopping cart with the changed data.
    can anyone tell me how we can update the SHOPPING CART with the changed contracts data, i have used BBP_PD_SC_UPDATE, BBP_PD_SC_SAVE and other shopping cart FM but nothing is happening.
    Thanks
    Tanveer

    Hello,
    What version of SRM are you on?  Have you check for OSS Notes?  I have had trouble with BBP_DOC_CHANGE_BADI but it was because of other issues.  The BADI works pretty well and it is called almost every time something happens to the shopping cart.
    I have noticed that sometimes that values are not changed til the second calling of the BADI.  I have yet understand why but I think it has to do with prompt processing. Usually, we train our requisitioners to click the 'Check'  button to flush things out.
    I don't know if I was helpful.... another thought.... could there be an error caught by BBP_DOC_CHECK_BADI that is preventing change in BBP_DOC_CHANGE_BADI?

  • What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?

    Hi All,
    I am new to TestStand. Still in the process of learning it.
    What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?
    Thanks in advance,

    Solved!
    Go to Solution.

    Hi,
    Using the Parameters is the correct method to pass data into and out of a sub sequence. You assign your data to be passed into or out of a Sequence when you are in the Edit Sequence Call dialog and in the Sequence Parameter list.

  • Passing data from one frame to another frame

    hello all, i am having a problem with passing data

    thank you
    the original problem sounded like an ideal opportunity to use Modal Dialog. if you want one frame to display another to get user input then you need to stop the method in the main frame from executing until you recieve a valid input.
    you can use your own class and keep all of the components that you have in the connect frame but you would have to extend JDialog instead of JFrame.
    there is a way around it!
    if you must use JFrame for both, then you need to have access to the main frame in the connect frame, maybe pass the pointer to the constructor??
    anyway, when the connect frame is done with its duties, you have to use the pointer to call another method in the main frame that will continue the process. otherwise main frame doesn't know when connect frame is done and by that time, the method in main frame that instantiated the connect frame has long since died.
    also, it allows things to happen in the other window that you may not want to happen until the connect frame is done
    typically users of software start clicking around on things and you could have three or four connect frames going at the same time
    it's really best to use a Modal Dialog, it really can look just like a JFrame!!!!!!!!!!!!!!

  • Pass data from a variable to another page

    Hi,

    drag and drop a list form data control onto your page as SOC.

  • Passing data from one screen to another(web-dynpro) in SRM sourcing cockpit

    HI Experts,
    i am facing problem in passing data from one web-dynpro screen and assigning the data it to another web-dynpro screen.
    my requirement is that when ever user selects a contract in PROPOSE SOURCES OF SUPPLY screen popup and press only assign only button, the data of the contract should be copied to the shopping cart.
    i have already used the BADI BBP_DOC_CHANGE_BADI, but unfortunately it was not working.
    so i tried to use the context, element and other web-dynpro fields to pass the data, i am able to pass the data from the popup to the second screen and able to assign it.
    but when ever i deselect the shoppping cart which has been assigned with the data of the popup and select another shopping cart the data of the above shopping cart is cgetting changed.
    i am unable to figure out the exact reason why this is happeing.i have written code in the ASSIGN ONLY button method to fetch the popup data and in the WDONMODIFYVIEW method of the second screen to assign the popup data to the shopping cart.
    i have tried to bind the elements using the BIND_TABLE, BIND_STRUCTURE, BIND_ELEMENT, BIND_ELEMENTS methods, but nothing is working.
    can anyone suggest me where i am making mistake and try to solve the issue.

  • Best practice - Pass data from Custom Comp to Another Custom Comp

    Hi, id like to know what would be the best practice to pass data from a custom component to another custom component. Right now I got these options:

  • Pass data from one VI to another one

    Hi,
    I try to control a event structure in a VI with a boolean command from a second VI. I have been advised to "build a connector to pass any data from one VI to another one".
    Below an simple example: my goal is MyVItwo gives the result of a 2 numbers addition only when the boolean "MyBooléen" value changes in MyVIone.
    How can I realise this?
    Thanks

    It is not entirely clear what you are trying to do. I think that what you want is a main vi/subvi setup. The boolean control would be in the main vi and would be monitored by an event structure. When the value of the boolean changes the subvi would be activated. I have attached an example showing how this is done.
    In order to use a vi as a subvi you build a connector box. In order to do this you just right click on the vi icon at the top right of the front panel and select show connector. You then wire connections on the connector block to controls on the front panel. You insert the subvi into your main vi by choosing "Select a vi" on the functions pallette and browsing to the subvi.
    If you absolutely have to pass the data from one vi to another while running in parallel there are a number of ways to do it. Global variables will certainly work but are generally avoided by experienced LabVIEW programmers due to their potential caveats and the break in data flow. An alternative to global variables is the functional global, also called a LV2 style global. This is basically a non-reentrant subvi with an unitialized shift register which allows for data to be stored. For more information search this forum for LV2 globals.
    Another alternative is to obtain a reference to the control and operate on that reference. You could also use queues, notifiers, or occurences. Search the examples which shipped with LabVIEW for examples on using these operators.
    If you need any more information feel free to post back here.

  • Passing data from one subreport to another subreport

    Post Author: GISGuy
    CA Forum: Formula
    I have a report which is really a series of subreports with very few actually requiring a direct link to another.  What I am trying to do is compare dates between different subreports and do conditional formatting to highlight where a dependant data source has an older date than the parent data source.
    We use Crystal Reports XI release 2, and the data resides in ArcSDE & Oracle 9.
    Any suggestions would be greatly appreciated.

    When your tagline is about the size of your post, you probably didn't convey much.
    You can pass values from one subreport to the next in the order they are placed in the main report by using shared variables, as in:
    //1st subreportwhileprintingrecords;shared datevar MyDate := {table.date}
    //2nd subreportwhileprintingrecords;shared datevar MyDate;if {table.date} = MyDate thencryellowelsecrwhite

  • How to pass data from one session to another?

    What does SAP memory use to pass data between sessions?
    What is the syntax of "Export to ..."? Where is it used?

    hi suman vijay,
    EXPORT obj1 ... objn TO MEMORY.
    Exports the objects obj1 ... objn (fields, structures or tables) as a data
    cluster to ABAP/4 memory .
    EXPORT obj1 ... objn TO DATABASE dbtab(ar) ID key.  Exports the objects obj1 ... objn (fields, structures or tables) as a data cluster to the database table dbtab.
    IMPORT f itab FROM MEMORY.
    Imports data objects (fields or tables) from the ABAP/4 memory . Reads in all data without an ID that was exported to memory with "EXPORT ... TO MEMORY."
    IMPORT f itab FROM DATABASE dbtab(ar) ID key. imports data objects (fields, field strings or internal tables) with the ID key from the area ar of the database dbtab .
    EXPORT obj1 ... objn TO MEMORY.
    If you call a transaction, report or dialog module (with CALL TRANSACTION , SUBMIT or CALL DIALOG ), the contents of ABAP/4 memory are retained, even across several levels. The called transaction can then retrieve the data from there using IMPORT ... FROM MEMORY .
    Each new EXPORT ... TO MEMORY statement overwrites any old data, so no data is appended.
    EXPORT obj1 ... objn TO DATABASE dbtab(ar) ID key
    The database table dbtab must have a standardized structure .
    The database table dbtab is divided into different logically related areas ( ar , 2-character name).
    You can export collections of data objects (known as data clusters ) under a freely definable key (field key ) to an area of this database.
    IMPORT allows you to import individual data objects from this cluster.
    thanks

  • Passing data from one transaction to another

    Hello ,
    I have internal table  as a result of user  selection on the selection screen of first transaction.
    Internal table can have any number of  lines that have to be processed in second transaction.
    How I can pass data ( list ) from first transaction to second one.
    Please advice
    Krsto

    Hi Krsto,
    Firstly i didnt understood the concept of transactions.
    U can pass the data of one views table selcted data into the other or to capture the data  .
    Try using these two methods
    1. Cal method get_selected_elements.
    2. Or else if u want whole table data to be captured then use Get_static_attributes_table
    I am sure by one of this methods yuor data will be passed.
    This methods are used for the table data selected will be captured and write the code accordingly as u wish
    regards,
    Sana.

  • Programming logic, passing data from a page to another

    Hi,
    I just began with developing with APEX 4.1.1, and I think I don't get how I should use it efficiently, I am more used to C-like programming.
    I have a table which contains the state of some electricity meters taken at some non-regularly spaced dates. I want to make a chart of the electricity consumption, e.g for each month. This (I think) implies that the application must do that (I used this logic for the same application made with php and sqlite and it worked):
    - User chooses a meter
    - Application tells him the available range of dates and the mean interval between measurements
    - User chooses the range of dates and the interval
    - Application verifies that the range of dates is valid (not outside the real data)
    - Interpolate the state of the meters at the requested regular interval
    - Calculate the consumption for each interval (simply a difference)
    - Draw the chart
    For now, I created some procedures which should pass a custom data type containing all the meta-data about the chart and a PL/SQL table containing the actual data to be charted, but I'm stuck at the point of interacting with the user (meaning writing the output of the procedures on a page and passing them to the next procedure and also charting that pl/sql table).
    Maybe should I create a temporary table ? But of what I read, this is a "real" table stored on the disk, and I just need this data once (and it is a small dataset, at most 20 points or so) for drawing a chart. This table should also be specific to the chart currently being created, it could happen that the same user or different users make multiple charts at the same time (like in two firefox tabs).
    I hope my post is not too confused..

    APEX is intended for the development of database centric applications. It's a physical implementation of Tom Kyte's philosophy of database application development&mdash;possibly replacing Java with JavaScript ;-) .
    To use it efficiently you need to stop thinking procedurally in C-like terms and think in terms of the set operations that SQL uses effectively.

    You should be aiming to collect and validate the required parameters in APEX session state values and use the built-in charting capability with SQL data sources that use these parameter values in query predicates.
    If you really can't generate the chart series from queries run on the original table, generate the chart data using an APEX collection rather than a "PL/SQL table" (preferred terminology is "collection type", but it's even better to specifically say "associative array", "nested table" or "varying array") or temporary database table.
    Maybe should I create a temporary table ? But of what I read, this is a "real" table stored on the disk, and I just need this data once (and it is a small dataset, at most 20 points or so) for drawing a chart. This table should also be specific to the chart currently being created, it could happen that the same user or different users make multiple charts at the same time (like in two firefox tabs).Temporary tables are rarely required in any Oracle application, but standard Oracle Global Temporary Tables are database-session specific and so have no concurrency issues. However there are issues when using them in APEX, so APEX collections are the preferred method for temporary, session-based storage.
