Question about event handling in a button

I recently coded a console version of my java program (just outputs stuff into the system console and a logger). I am now adding a simple GUI with a set of buttons to start and stop the program. In order to do this, do I just copy paste the main function contents of the console version of my code into the button's event handlers or is there a way I can just run the main class? I was googling for Class loading in java but I'm not sure if this is what I should be looking at... Can someone please help me out?

MyMainClass.main(new String[] { "the", "arguments" });
// or, if you defined your main to use varags (i.e. as "public static void main(String... args)") then you can just use
MyMainClass.main("the", "arguments");But you should really extract your functionality out of the main method into meaningful classes and methods and just use those from both your console code and your GUI code.

Question about event handling in JComponents

I have often found it useful to create a component that acts as an event handler for events the component generates itself. For example, a panel that listens for focus events that effect it and handle these events internally. (See below).
My question is: Can this practice cause synchronization issues or any other type of problem that I need to watch out for? Is it good/bad or neither. Are there any issues I should be aware of?
Thanks in advance for the help.
Example:
public class qPanel extends JPanel implements FocusListener
public qPanel () {
super.addFocusListener(this);
public void focusGained(FocusEvent e) {
//Do stuff
public void focusLost(FocusEvent e) {
//Do stuff
}

Hi,
Handling events this way is completely fine and saves on number of classes. Only thing you may want to watch out for is that the handler methods have to be public. This means that someone could use your component and call one of the methods. For example, I could write:
panel.focusGained(new FocusEvent(....))
when it's not really gaining focus. So, if you're writing this component for re-use you might want to be aware of this.
An alternative:
Use a single internal class to handle all events. It can then delegate to private methods of your component. Example:
class MyEventHandler implements FocusListener, MouseListener, etc... {
public void focusGained(FocusEvent fe) {
doFocusGained(fe);
public void mousePressed(MouseEvent me) {
doMousePressed(me);
Then your component could have:
private void doFocusGained(FocusEvent fe) {
private void doMousePressed(MouseEvent me) {
etc...
Just ideas :)
Thanks!

How to find event handler for save button in salesorders

Hi,
I want perform event based on save button in salesorders.Can you tell me how to find the event handler for
save button.
Regards,
Brahmaji

Brahma,
you can find the component, view details by doing an F2.
open the component, the view will be mostly an overview page i.e., the name ends OP etc.,
But your method name will be mostly EH_ONSAVE, you need to find exact view.
F2 does not come up properly for overview pages, you have to look into UI config tool preview and make sure sometimes.

Question on program structure about event handling in nested JPanels in GUI

Hi All,
I'm currently writing a GUI app with a wizard included in the app. I have one class that acts as a template for each of the panels in the wizard. That class contains a JPanel called contentsPanel that I intend to put the specific contents into. I also want the panel contents to be modular so I have a couple of classes for different things, e.g. name and address panel, etc. these panels will contain checkboxes and the like that I want to event listeneres to watch out for. Whats the best way of implementing event handling for panel within panel structure? E.g for the the checkbox example,would it be a good idea to have an accessor method that returns the check book object from the innerclass/panel and use an addListener() method on the returned object in the top level class/panel. Or is it better to have the event listeners for those objects in the same class? I would appreciate some insight into this?
Regards!

Unable to get automatic event handling for OK button.

Hello,
I have created a form using creatobject. This form contains an edit control and Search, Cancel buttons. I have set the Search buttons UID to "1" so it can handle the Enter key hit event. Instead its caption changes to Update when i start typing in the edit control and it does not respond to the Enter key hit. Cancel happens when Esc is hit.
My code looks like this -
Dim oCreationParams As SAPbouiCOM.FormCreationParams
        oCreationParams = SBO_Application.CreateObject(SAPbouiCOM.BoCreatableObjectType.cot_FormCreationParams)
        oCreationParams.UniqueID = "MySearchForm"
        oCreationParams.BorderStyle = SAPbouiCOM.BoFormBorderStyle.fbs_Sizable
                Dim oForm As SAPbouiCOM.Form = SBO_Application.Forms.AddEx(oCreationParams)
oForm.Visible = True
'// set the form properties
        oForm.Title = "Search Form"
        oForm.Left = 300
        oForm.ClientWidth = 500
        oForm.Top = 100
        oForm.ClientHeight = 240
        '// Adding Items to the form
        '// and setting their properties
        '// Adding an Ok button
        '// We get automatic event handling for
        '// the Ok and Cancel Buttons by setting
        '// their UIDs to 1 and 2 respectively
        oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
        oButton = oItem.Specific
        oButton.Caption = "Search"
        '// Adding a Cancel button
        oItem = oForm.Items.Add("2", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 75
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
        oButton = oItem.Specific
        oButton.Caption = "Cancel"
oItem = oForm.Items.Add("NUM", SAPbouiCOM.BoFormItemTypes.it_EDIT)
        oItem.Left = 105
        oItem.Width = 140
        oItem.Top = 20
        oItem.Height = 16
        Dim oEditText As SAPbouiCOM.EditText = oItem.Specific
What changes do i have to make to get the enter key to work?
Thanks for your help.

Sheetal

Hello Felipe,
Thanks for pointing me to the correct direction.
So on refering to the documentation i tried out a few things. But I am still missing something here.
I made the following changes to my code -
oForm.AutoManaged = True
oForm.SupportedModes = 1 ' afm_Ok
oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
oItem.SetAutoManagedAttribute(SAPbouiCOM.BoAutoManagedAttr.ama_Visible, 1, SAPbouiCOM.BoModeVisualBehavior.mvb_Default)
        oButton = oItem.Specific
        oButton.Caption = "OK"
AND
oForm.Mode = SAPbouiCOM.BoFormMode.fm_OK_MODE
oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
oItem.AffectsFormMode = False
I get the same behaviour OK button changes to update and enter key does not work.
Could you please tell me find what is it that i am doing wrong?

Sheetal

[JS] Basic question about event listeners and event handlers

I am very new to the whole topic of event listeners and event handlers. I'd run the test for the following problem myself, but I don't know where to start, and I just want to know if it's impossible -- that is, if I'm misunderstanding what event listeners and event handlers do.
Say I have an InDesign document with a text frame that is linked to an InCopy story. Can I use an "afterImport" event listener on the text frame to perform some action any time the link to the InCopy story gets updated? And will the event handler have access to both the story that is imported, and the pathname of the InCopy file?
Thanks.

Thank you, Kasyan.
Both of those are good solutions.
We are currently using InDesign CS4 and InCopy CS5. I'm hoping to get them to purchase the whole CS5 suite soon, since I'd like to start writing scripts for InDesign CS5 as soon as possible, as long as I'm going to have to be doing it in the not too distant future anyway. The greater variety of event handlers sounds like it might be something that is crucial to the project I'm working on, so that adds to the argument for getting CS5.
Thanks again. You have no idea how helpful this is. I made some promises to my boss yesterday that I later realized were based on assumptions of mine about the InDesign/InCopy system that didn't make any sense, and I was going to have to retract my promises. But after reading your response I think I can still deliver, in a slightly different way that I had been thinking before.

Hi Craig,
Just worked on the code sample you provided. Heres' how my code looks in OnInputProcessing segment:
      Some internal table population code here
then the following code segment:
file = 'C:\ZSS.XLS'.
event = cl_htmlb_manager=>get_event_ex( request ).
IF event IS NOT INITIAL AND event->event_id = 'Dwd_Excl'.
results = 'Button was pushed'.
ENDIF.
IF results = 'Button was pushed'.
CALL FUNCTION 'WS_EXCEL'
    EXPORTING
      filename      = file
    TABLES
      data          = t_zsstabl
    EXCEPTIONS
      unknown_error = 1
      OTHERS        = 2.
IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
ENDIF.
The problem is that when I push the Download to Excel HTMLB Button, the following Error is being displayed on the page :
500 SAP Internal Server Error
Error message: Exception condition "NO_BATCH" raised. ( type of termination: RABAX_STATE )
The Layout part code is :

Question about displaying handler errors in the webdynpro

Hello all, Please forgive any EM terminology mixups as I am new to this unique module!
     Here is my scenario, I am in EM WebDynpro and updating the actual dates on a purchase req. The event handler accepts the date I entered and in the background makes a synchronous rfc call to ECC to update the related project with the new date. This rfc call fails because I have the project open and it is locked. This call is synchronous so I get the error right away and I set the return code to 4 and populate an error message that I want passed back to the user in WebDynpro. For some reason the EM system is ignoring this error and returning to the user a successful 'sent' message.
EM WebDynpro --> Purchase Req --> PO Approved Actual Date entered --> synchronous RFC to ECC to update Project --> project locked error returned by ECC --> error message populated in EM --> EM WebDynpro returns as if it was successful
I have put in breakpoints to ensure I was populating error messages back to EM and I see the details flowing back that are correct, but no details are returned to the actual user. If I go to the Event Handler Overview in the GUI I can find my error message recorded there. Problem is our users will be working from the Web primarily and would not see this message in a normal course of work.
Is there a config piece that I should be setting to return this error to the users in WebDynpro? This seems like a trivial/standard piece of functionality so I am confused as to why it is not showing up in the dynpro.
Thank you for any help or ideas and points awarded of course!
John

Hello Berthold,
   I believe we understand what you are saying we should do and we have mimicked the activity you described. Now we are running into a short dump when the system tries to process the RETRIEVE MSG method. The code is looking for the class /AIN/CLPUB_ID_CONVERT for some reason. This class does not exist in this release. There is a /SAPTRX/ class that matches.
So in /SAPTRX/CL_PUB_ID_CONVERT method CALL_AII_FOR_SINGLE_ID at line 45 there is this statement:      CALL METHOD (co_ain_class_name)=>(co_ain_method_id_mapping). Since this is a dynamic class/method call we think we must have something still incorrect in the IMG so we are going through troubleshooting and looking at OSS Notes. No luck so far.
Any additional input or ideas as to possible missed steps would be greatly appreciated.

UIX-XML BC4J Question regarding event handling

How can I use/access Application Module, defined in UIX-XML page (using <bc4j:registryDef>), in my event handler method ???

Sorry for the confusion. I figured out what you were asking.
The right way is this.
First, in your UIX XML page, declare your handler like this:
<event name="%myEvent%" >
<bc4j:findRootAppModule name="%ModuleName%" >
<method class="%eventclass%" method="%eventmethod%" />
</bc4j:findRootAppModule>
</event>
the strings in the % have to be replaced with your own particular names. %ModuleName% should be the same as the name of the module in the registry.
Then in the event handler %eventclass%.%eventmethod% you can use this to find the Application Module:
oracle.jbo.ApplicationModule mymodule
= oracle.cabo.data.servlet.bind.ServletBindingUtils.getApplicationModule(context);
"context" is passed in to your event handler as a BajaContext. ServletBindingUtils has several other methods for getting BC4J stuff, you should look at its definition.

A question about how to change a button in a JPanel during runtime

I am a beginner of GUI. Now I am trying to change a specific component, a button, when the application is running. For example, I have 3 buttons in a JPanel. Each button has its onw icon. If I click one of them, it will change its icon, but the other two don't change. I don't know if there is any method for changing a specific component during runtime. If any one knows please let me know, I will appreciate that very much!!!

What you're going to have to do is loop inside the actionlistener but still have accessability to click while its looping. I don't know much about it, but I think you're going to need a thread. Try something like this... (it doesn't work yet, but I have to take off)
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
class buttonxdemo extends JFrame implements ActionListener{
Buttonx mybutton;
//set it all up, make it look pretty =]
public buttonxdemo()
     mybutton = new Buttonx("default");
     getContentPane().add(mybutton.thebutton);
     mybutton.thebutton.addActionListener(this);
     this.setDefaultCloseOperation(3);
     this.setSize(200,200);
public void actionPerformed(ActionEvent ae){
    if (ae.getSource() == mybutton.thebutton)
         if (mybutton.keepGoing)
           mybutton.keepGoing = false;
          else if (!mybutton.keepGoing)
               mybutton.keepGoing = true;
      mybutton = new Buttonx(/*Icon,*/"My Button");
      //getContentPane().remove(mybutton);
      //getContentPane().add(mybutton.thebutton);
      mybutton.startstop();
}//actionperformed
static void main(String args[])
     new buttonxdemo().show();
} //movingicondemo
class Buttonx extends Thread{
public boolean keepGoing;
//public Icon ICx;            //perhaps an array, so you can loop through?
public String strbuttonx;
public JButton thebutton;     //may have to extend JFrame?
public Buttonx(/*Icon IC,*/ String strbutton){
    //ICx = IC;
    strbuttonx = strbutton;
    thebutton = new JButton(strbuttonx);
public void startstop()
    int i = 0;
    while (keepGoing)
      thebutton.setLabel(strbuttonx.substring(0,i));
      //if an array of Icons ICx
      //thebutton.setIcon(ICx);
i++;
if (i > strbuttonx.length() - 1)
i = 0;
try
     Thread.sleep(1000);
catch (InterruptedException ie)
     System.out.println("sleep caught: " + ie);
}//startstop()
}//buttonx

MDM iView resultset problem and question about eventing

Hi experts,
I created a MDM iView resultset for my main table as search table (comparison is not supported). When I click on preview I get an empty table ("Found <Tablename>: 0 of 10", table contains 10 entries at the moment). I tried the same with a subtable and everything works fine (all entries have been in the preview table). Any ideas why I don't get a result?
My 2nd question: can I choose the parameter name in eventing (EPCF) on my own? So if I have Vendor_Id as field can I use vendorid as parameter name? Do I have to define anything in the listener iView (e.g. in detail iView for an event from resultset iView)? Maybe you have a useful tutorial link (please not SAP help section)?
Thanks for your answers.
Regards, bd

It is possible to retrieve the number of rows from a resultset --
Statement stmt= con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
                                    ResultSet.CONCUR_READONLY);
ResultSet rs= stmt.executeQuery("<your select query here>");
int totalRows;
if (rs.last()) // can it move to the last row?
   totalRows= rs.getRow(); // get its row number
else
   totalRows= 0; // no rows in the resultset
rs.first() // set the cursor back to the startNote that the resultset has to be scrollable (TYPE_SCROLL_INSENSITIVE).
kind regards,
Jos

Question about Events stored on an external drive

Hello guys! I recently freed up a TON of space on my iMac by adding an external hard drive and you guys advised me on how to get iMovie '08 to store my Events there.
Question: I'm going to Rome Italy tomorrow and I'm going to be doing a ton of video footage. My Macbook doesn't have the hard drive space to hold what I'm going to be shooting.
So, my question is......considering that I'm using this external drive to store Events from my iMac will I be able to to use that same external drive on this trip to manage Events on my MacBook?
In other words, I just want to make sure that I don't confuse either version of iMovie that I have operating on these two different machines. Can I use this same external hard drive to manage Events from both machines?
Thanks in advance for the speedy assistance. I'm leaving tomorrow and need to get this issue nailed down.
Thanks!
Tony

I actually have no set-up to test my speculations but...:
when you tell iM08 to store Events on some ext. drive, it creates on 'Top Level' of that drive the 'iMovie Events' folder..
so, when you do that with a second Mac/iMovie... I guess, it will confuse the file management.. (=you can not create two indentically named folders... ) ... and, I guess, you can not create/select a sub-folder for the Events...
best practise would be to partition the drive.. but that isn't possible without erasing any content on your drive..
Plan B) invest 100$ for a 2nd drive.. ? (last week offer: 79€ for 500 gigs.. no bad... )

Question about touch handling

Hi,
I have a view that is handling touches. I have a tabbar in the same view. I can determine when touch is made in the area where there is a tabbar .
The problem is that I want the events inside the tabbar area to be handled by tabbar did select method but could not find a way to do this . If touch handling is on event inside the tabbar has no effect.
Please help
