Event handling for closing a browser window on portal in web dynpro abap

Hi,
I am new to portal as well as web dynpro. Is it possible to handle portal events in web dynpro abap? My requirement is whenever a browser window is closed on portal, if any new system messge has been added I want to display them in a pop-up. I checked examples from the package 'SWDP_TEST' but they trigger events in web dynpro and pass them to portal. I want to subscribe to the close event of portal and handle it in my web dynpro abap application. How can I achieve this? Please suggest.
Thanks and regards,
Amrutha

Hi,
I dont think that you can code to close IE browser window as you cannot access MS IE APIs in WD ABAP. I looked into closing IE browser and got http://p2p.wrox.com/general-net/16588-handling-ie-close-event.html . reading this, it seems the coding can be done in C#(asp) etc.
also refer Closing of IE window
I hope this is useful for you.
Thanks,
Chandra

Html code for closing the browser window on logoff.

Hello,
I am using the logoff redirecrt url feauture to divert the logoff page to a custom made html page. I want this page should be closed automatically after being called i.e. when I click the logoff button it should divert to this custom html page and than close the browser automatically.
Can you please help me with the code for this custom html page so that it closes the whole browser automatically when it get called.
Regards

Don't know about the coding. May be we can do it by setting the property
Initial State - Open or Closed or may be make that window Invisible.
Others will advice you soon related to this.

Sleutel Bind, fancy key events handler for standalone window managers

I began using Openbox in my laptop a while ago, and I was amazed by the speed, customization and simplicity it provides. After I started customizing my desktop I noticed that some of the special keys (TouchpadToggle, Volume, PrintScreen, etc) didn't worked at all. There are some applications for the Volume keys to work, but not for keys like touchpad-toggle and print-screen. Of course, there's a workaround for each case using simple scripts, but I wanted something a little more fancy, so I made:
Sleutel Bind
It's made in C and provides key events handling for:
XF86TouchpadToggle
Print (prtsc key)
It makes use of libnotify to display states ( touchpad enabled/disabled, screenshot taken, etc) and imlib2 (a very popular library, probably already installed in your system) to grab the screenshots. Almost all other keys are covered already by another application, but if needed, more key events will be added in the future.
Feel free to post your thoughts about Sleutel Bind, it's my first contribution to the community.
How to use
Once installed just run the command as a normal user.
If using openbox, place the following command in the "~/.config/openbox/autostart" file:

Do you still have issues with the latest version? Otherwise I will mark this thread as solved.
well, still do not work... But I do not want to try it any more...So you can mark.

An event handler for several subclasses.

I've been trying to write an event handler that is parameterized by a window
being passed to it. The event handler is intended to handle the exception event
that occurs when the window completes. I have had problems trying to write this.
The scenario is as follows.
I have a task that listens to events that respresent requests for a window being
opened. On receiving these, it starts the window, also as an asynchronous task.
The windows that may be opened (say window classes B, C, and D) are all
subclasses of window class A. The event handler that I register for (after
instantiating the window) takes a window of class A as parameter. It responds to
the exception events for the Display() method of window passed in.
Now the problems I have encountered are as follows :
To allow the event handler to respond to the exception event of a window of
class A, class A has the exception event defined for it. To allow me to start a
window of class B where completion = event, I also have to define the same
exception event. This hides the return and exception for class A. The
implications of this in the event handler is that the event cannot be trapped
unless I cast the parameter passed in into class B on the ' when return_event '
line. This makes the event handler specific to class B.
(This situation is also presumable caused by the fact that each subclasses
overrides the Display method of window class A, and the exception event is
defined for the Display method.)
An alternative approach I tried was using interfaces. I defined the exception
event as an event on an interface. This was defined with the same parameters as
the exception events of classes B, C, and D would have (ie. the exception
event had two parameters - one of type GenericException, and one of ErrorMgr). I
then made classes B, C, and D implement the interface. The event handler
parameter would be the interface rather than class A. However class B would not
compile as the GenericException parameter for the event in the interface uses
the input mechanism, but the GenericException parameter for the exception event
in the display event of classes B, C, and D uses copy input. I have ben unable
to find a way to change the mechanism for event parameters.
Has anybody got any ideas as to how I may be able to achieve the goals of an
event handler that can respond the exception event of a number of subclasses.

Steve,
Try this. Have a method in your super class A , say StubDisplay
which processes the event loop.
Also make this method return Exception and/or completion events you
desire.
Instead of overriding Display() in your sublclasses, override this
StubDisplay method.
You need not have to redefine the exception/completion events in
your sublclasses B,C ..because they naturally inherit from the super class
A.
Using interfaces may not be a good idea in this case because, you
will be forced to implement them in your subclasses even if you dont
need them in some specific cases.
Good luck!

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

Closing the browser windows created by web.show_document and javascript

From Forms I am issuing a http request using web.show_document and javascript:window.open(). The http request makes a remote procedure call to a coldfusion component on a JRun appserver. I want this rpc to fire in the background so that the current forms browser window remains as is.
The logic is as follows
l_rpcURL := 'http://....just a standard URL.....'; -- edited for this thread
l_jsURL := 'javascript:window.open("' || l_rpcURL || '","","fullscreen=no,titlebar=no,location=no,toolbar=no,menubar=no,status=no,resizable=no");self.close();';
WEB.SHOW_DOCUMENT (l_jsURL,'_blank');
The http request works fine but leaves a browser window behind. It's the one created by the javascript.window.open(). If I remove the self.close() from the javascript then I have two browser windows open, one from web.show_document and the other, as described previously, from the window.open().
Any idea how I can force closure of the window opened by the window.open() ?
Thanks

Hi,
did this occured afer installing service pack 2?
A work around is The only solution that is to create a close.html file and calling this file in the code: Web.show_document('http://server:port/close.html','_self');
<html>
<body onload="closeit()">
<script>
window.close();
</script>
</body>
</html>

EmailRecieved Event handler for incoming email in Sharepoint 2013

Hi,
I am developing custom event handler to enable incoming email for custom document library. i have couple of questions.
1. Once i attached the event handler, i could see incoming email settings for the custom document library, but it displays only 2 options as below :
              1. Allow this document library to recieve email
                             Yes       No
                2. E-mail address
All other properties are not displaying. Is this normal behaviour on custom event handler for custom document library or any issue anywhere?
2. So i have given other properties using powershell as below:
$list = $web.lists["invoice Documents"]
$list.EmailAlias ="TestDocument"
$list.EnableAssignToEmail = $true
$list.rootFolder.Properties["vti_emailusesecurity"] = 1
$list.rootFolder.Properties["vti_emailsaveattachments"] = 1
$list.rootFolder.Properties["vti_emailattachmentfolders"] = "root"
$list.rootFolder.Properties["vti_emailoverwrite"] = 0
$list.rootFolder.Properties["vti_emailsavemeetings"] = 0
$list.rootFolder.Properties["vti_emailsaveoriginal"] = 0
$List.RootFolder.Update();
$list.Update();
here i have given vti_emailusesecurity as 1, so it should allow incoming email for the user who has permission for the list.
But any user from the domain is sending mail to this list, the Emailrecieved event handler is triggered. I am expecting that this event handler should not be triggered and expecting access denied error in the ULS Log. But that is not happening, and emailrecived
is triggered and email is delivering to this address successfully.
Can you please anyone help if experience on this?
Thanks
Sathya

How to add event handling for a menu?

hi,
I have created a menu and few mneu items.
for eachmenu itme , i did event handling and it is workign fine.
it was like this
menuItem = new JMenuItem("Exit",KeyEvent.VK_X);
menuItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_X, ActionEvent.ALT_MASK));
menuItem.addActionListener(this);
menu.add(menuItem);
     public void actionPerformed(ActionEvent e)
JMenuItem source = (JMenuItem)(e.getSource());
String s = "Action event detected. Event source: " + source.getText();
System.out.println(s);
public void itemStateChanged(ItemEvent e)
JMenuItem source = (JMenuItem)(e.getSource());
String s = "Item event detected. Event source: " + source.getText();
System.out.println(s);
now int he second menu i don't have any menu item and i want to do the event handling for the menu itself. any ideas how to do it. following is the code for the menu
//Build the second menu.
menu2 = new JMenu("Options");
menu2.setMnemonic(KeyEvent.VK_O);
menuBar.add(menu2);
menu2.addActionListener(this);     //this does nto work

You were on the right track. However, selecting a menu is different from selecting a menu item. MenuItem chucks an ActionEvent and Menu will send an ItemEvent.
If you pile all action output to one actionPerformed method then be careful of your assumptions on what the source type will be. If by any chance the Menu has sent an ActinoEvent then your code will have caused a ClassCastException.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MenuTest implements ActionListener, ItemListener {
    JMenuItem menuItem;
    JMenu menu1, menu2;
    JMenuBar menubar;
    JFrame frame;
    public MenuTest() {
        frame = new JFrame("MenuTest");
        frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);
        menubar = new JMenuBar();
        frame.setJMenuBar(menubar);
        menu1 = new JMenu("File");
        menu1.setMnemonic(KeyEvent.VK_F);
        menuItem = new JMenuItem("Exit",KeyEvent.VK_X);
        menuItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_X, ActionEvent.ALT_MASK));
        menuItem.addActionListener(this);
        menu1.addItemListener(this);
        menu1.add(menuItem);
        menubar.add(menu1);
        //Build the second menu.
        menu2 = new JMenu("Options");
        menu2.setMnemonic(KeyEvent.VK_O);
        menu2.addActionListener(this); //this does not work
        menu2.addItemListener(this); // use this instead
        menubar.add(menu2);
        JPanel panel = new JPanel();
        panel.setPreferredSize(new Dimension(100,100));
        frame.getContentPane().add(panel);
        frame.pack();
        frame.show();
    public void actionPerformed(ActionEvent e)
        String s = "Action event detected. Event source: " + e.getSource();
        System.out.println(s);
    public void itemStateChanged(ItemEvent e)
        String s = "Item event detected. Event source: " + e.getSource();
        System.out.println(s);

Event handler for STDIN input?

Hi,
This question will probably require a bit of context - I'm attempting to re-implement in java an application that's currently written in perl. The application is a server helper app that rewriters urls; it receives a request ID and a URL on stdin, does the necessary munging (which can require an external SOAP query), then returns the resulting rewritten URL.
Since the results can be asynchronous due to the need for external queries to build the result, this is currently a multithreaded perl app implemented using perl's POE framework to register an event handler for stdin. That handler fires each time a line of input is received, then feeds the query to a thread pool manager (POE::Component::Pool::Thread, which is conceptually similar to the Executor frameworks). The thread returns the result as a callback registered to another function in the main thread, which then populates the query/result to a cache then outputs the result (with the original query ID) on stdout. Since stdin input and the result callbacks are event-driven, there's no while(true) main loop or other blocking mechanism in the main thread. Unfortunately, it's perl-ness is causing problems due to perl's threading implementation (three words: "copy on init"), so we need to reimplement in a language with a more robust threading implementation (preferably one with copy-on-write for shared objects). So, Java it is.
So far everything's been good - Executor, Callables, and Futures work as I hoped they would for proper thread management, and the internal worker thread logic (XML processing, SOAP, regular expressions, etc) is proving rather simple to adapt. However, the main roadblock I'm hitting is that so far, I have not found a way to register any sort of event handler for STDIN input (or more specifically, InputStreamReader/BufferedStreamReader events). This could be due to search engine pollution - everything I see when I search for documentation on event listeners appears to be GUI-specific (buttons, menus, text areas/forms, etc). I'm just looking for a way to handle a line of STDIN, not a text area on a form.
Any pointers in the right direction will be much appreciated!

Maybe I need to rethink the design here...
The main reason I used a callback in the original perl is that there's a large cache structure that gets checked before the thread dispatch, and only cache misses get pushed to a thread for processing. Callbacks from the threads will then add its results to the cache. Thanks to perl's thread model, when I attempted to make the cache a shared structure - in perl, you have to explicitly mark as "shared" variables that you want visible to all threads - the structure wound up getting copied to every thread, and this gave the app an unacceptable memory footprint. So the solution was to use a callback in the main thread to update the cache.
I'm now thinking that if Java's thread model is a bit saner (i.e. a shared object doesn't get copied into every thread), then I could just have each thread update the cache, print its output to STDOUT directly, and avoid the need for the callback. I can then make my input loop simply a while() loop, waiting for the next input to dispatch. Sound sane?Yes I think so.
There is some of this I still don't entirely understand. Your loop sounds better now but it sounds to me like the process is this.
1) read from in
2) call some stuff on the basis of what came in
3) do work
4) workers produce things
5) things written back out
6) read back in??
If you're just going in/out then great. If you are going in/out/in then maybe some sort of PipedInput/Output Streams? It may well be that I got lost in your explanation in which case never mind.

Issue Tracker app closing the browser window on chart page

Hi!
I am walking through the Issue tracker tutorial. I have created page 10 (Issues Resolved by Month) which is the chart page. Everything looked fine until I try to run the page. Then it simply closed the browser window after it authenticates me. Anyone else see this? Any ideas?
Thanks!

Probably a problem with your SVG viewer installation. Does it happen on other chart pages as well? What browser/svg viewer version combination are you using? There are some known issues with what's labeled as the current svg viewer on Adobe's website and Firefox.

Override event handler for document events in LiveCycle

I would like to have an email notification when a user opens a policy-protected DRM pdf. Is there a way to override the event handler for Document Open events?
Or perhaps there is a way to access the event database- where can I find this information?

Thank you so much for your reply. I have created an external authorization and am following the steps outlined here: http://help.adobe.com/en_US/livecycle/9.0/programLC/help/index.htm?content=001479.html
I have deployed my jar and restarted JBoss. However, now when I try to create a new policy using my external authorization, I do not see an option to add it on the create new policy page. I see only sections for Users and Groups, General Settings, Advanced Settings, and Unchangeable Advanced Settings. Could you please tell me how to add the external authorization?
Also, in the component.xml file, I followed the sample and kept this line: <component-id>com.adobe.livecycle.samples.externalauthorization</component-id>
Should that be changed? If so, to what?
Thanks.

Event Handling for Graphic Shapes

Hi guys,
I have a problem on the implementation of a piece of software that i'm making, to be more specific i implement a GUI. In this GUI i draw rectangles, lines and that kind of things.
The problem is that i want when clicking on a rectangle, an event to take place such as the drawing of something else, or a message, etc.
How am i to achieve that? I've tried many things but didn't succeeded it unfortunately. How am i going to "give" life to my rectangles by adding event handling for them? What code should i write?
Note: My class extends JPanel & i'm using paint(Graphics g) for drawing the shapes

Event handling operation on other software windows

Hi friends
I am able to execute another external program through java code using
Runtime.getRuntime().exec();
But now I want to perform Event Handling operation on such a opened external program(software) window.
Is it possible in Java to perform Event Handling operation on other software windows.
Thanks

Can anybody give me some idea. I already gave you hte idea. I told you to write the C++ code to do it. There is no other way. You cannot do that from Java.
WRT the sockets post:
whether you use JNI or sockets: the accessing code will still not be written in Java. Hence you still can't do it in Java.

Event handling for textfields

I would like to make ONE event-handler for users who
- presses Return/Enter from a field or
- uses the mouse to jump to another field or
- uses the tab-key to jump to another field.
Can this be handled by using only one event-handler, ex. focusLost ?
I appreciate your answer.
Have a nice day.

I used a single FocusListener with 3 different TextFields to select all the text in a TextField whenever the TextField gained focus, plus updated the other 2 TextFields based on the contents of the third when the third lost focus. Is that like what you are looking for?

How to use common event handler for selected movie clips?

I have a 50-state map in a flash movie. Each state is a movie
clip.
Goal: when mouse moves over a state or is clicked in a state,
the state will be highlighted in a bright color and a small box
will pop up near the state and display some information about the
state.
Question: I know I can add mouse event handler for each state
movie clip. But this is simply not good since this has to be done
50 times and codes thus scattered different places. Ideally, I only
want to have one script that determines where the mouse position is
when events trigged and then do right things (highlight the state
and display info. in a pop-up). How can this be implemented?
Thanks!

There are a number of ways. Which way is best depends on how
you have things set up so far.
E.g. If they have an enumerable naming convention:
e.g. each clip is like state_0 , state_1 etc.
Then you can loop through them and assign them all to the
same mouse event handler via the loop. You would need properties
other than the name of the clip to identify the state. E.g. each
clip could contain its own data or the index could be a pointer to
the state data (objects with state name and info properties) in a
separate array.
//state clips named
for (var i=0;i<50;i++) {
this["state_"+i].stateindex=i;
this["state_"+i].onPress= statePressHandler;
var stateData:Array = [{name:"StateName,info:"this state
Info"}, name:"StateName,info:"this state Info"}, etc...]
function statePressHandler() {
trace(this);
trace(stateData[this.stateindex].name+"="+stateData[this.stateindex].info);
Other ways are possible too but the best approach depends on
how you have named the clips and whether you're creating them with
code or whether they're already on stage from authoring (my guess).
If they're already on stage and they're called "Alaska" etc, then I
would be inclined to put them all inside a container clip that
contains nothing else other than states. It would avoid the need
for an array of clip names or for checking some other specific
property of each clip to determine if its a 'state' clip and not
something else in a for..in loop.
