How to write events
What is actually responsible for propagating an event. Should in case I want an event to be triggered when a value changes.
My approach was to make a watching internal Thread class call the Listener when the value changes. Is this a simple approach to event-based programming?

http://java.sun.com/j2se/1.4.2/docs/api/java/beans/PropertyChangeListener.html
http://java.sun.com/j2se/1.4.2/docs/api/java/beans/PropertyChangeEvent.html
Then, wherever you change the value, you send a PropertyChangeEvent, and anyone who has registered a PropertyChangeListener can be notified.
No sense re-writing something that already exists.

How to write events and event handlers?
Any samples?
ThanksYou can generate your custom events and it is very easy.
You will have to extend the EventObject class in order to make an class representing the event.
Iam giving a brief eg:
class MyEvent extends EventObject
MyEvent(Object source)
super(source);//source which generated the event.
//your own code
interface MyEventListener
public void myEventPerformed(MyEvent e);
class abc
java.util.ArrayList arr;
abc
arr = new java.util.ArrayList();
public synchronized void addMyEventListener (MyEventListener l)
arr.add(l);
public synchronized void removeMyEventListener (MyEventListener l)
arr.remove(arr.indexOf(l));
protected void notifyTransEvent(Object source)
MyEvent tEvent = new MyEvent(source);
Iterator itr = arr.iterator();
Iterator itr = arr.iterator();
while(itr.hasNext())
((MyEventListener)itr.next()).myEventPerformed(tEvent);
Now anyone implementing the MyEventListener inetrface can be added in the ArrayList.The ArrayList is the list representing the interesting parties who want to receive the event.When registered they will receive the event.
This class abc is just like an component which on certain situations generate event.You can call notifyEvent in any case where you want the event to be generated.
You will then add this class to your main class as this
class xyz implements MyEventListener
abc obj;
xyz()
obj.addMyEventListener(this);
public void myEventPerformed(MyEvent e)
//your handling code
Hope this example will suffice. -
Use a "Write" Event on a Specific Drive or to a Specific Folder to Trigger a Task in Task Scheduler
I first posted this question on the Microsoft Community forum. It was suggested that I repost it here.
I have a question!
(Pleas forgive the long post...)
What I am trying to do: (This is what I have not yet figured out!)
I am trying to figure out how to trigger a task, in Windows Task Scheduler (WTS), whenever a "Disk Write" event occurs on a specified drive on the machine. - Or, more specifically, whenever a new file or folder is written or
saved to a specified Folder, or a specific Disk Partition, or a specific Hard Disk on the machine - whichever is more relevant for the end goal.
The overall goal:
When a "disk write" operation occurs and data is written to a specified location on a Hard Drive, start a Program at the beginning of the following hour, that will run a backup of the contents
of that location, (after - of course - the new data has been written). After the backup is complete, disallow the program from being started again at the beginning of the next hour, unless more data is written to the specified location beforehand.
Example:
At 2:27pm, I save a new word document to "D:\My Folder\". When the new Word doc file is saved to "D:\My Folder\", my preferred Backup software application is then scheduled to run a backup at the beginning of
the following hour - at 3:00pm - which will then create a new backup of "D:\My Folder\".
The backup software will NOT be scheduled to run again at the next following hour - at 4:00pm - unless another file or additional data is written to "D:\My Folder\" - between 3:00pm and 4:00pm.
Summary:
The goal here is to only run a backup at the beginning of the next hour, following a “disk write” event to a specified location on the hard drive.
Steps that I have, so far, on how to make this happen:
Whenever data is written to a specified location on a hard drive (i.e. "D:\My Folder\"), "Task A," in Windows Task Scheduler, will be triggered to execute its action.
The Action in "Task A" will run a script that changes the Status of "Task B" to ENABLED.
The Action in "Task B" will, on a continuous hourly schedule, start a program that will perform work on the machine. (In this case, it will run a Backup Task in my preferred backup software.)
Upon completion of work by that program (the Backup software), that program will run another script that will change the Status of "Task B" back to DISABLED; preventing "Task B" from continuing that program every hour
according to its hourly schedule.
How do I do this: ... ?
The thing holding me back on making this work is figuring out how to identify the source that generates the “disk write” event and event ID I need, so I can use it to trigger a task in Windows Task Scheduler - in the way that I need. Furthermore,
the “disk write” event needs to specific to a disk drive that I specify and if at all possible, specific to a location that I specify, i.e. “D:\My Folder\”.
Any help on this as well as other suggestions on making this work is greatly appreciated!

How to write an element in a JTable Cell
Probably it's a stupid question but I have this problem:
I have a the necessity to build a JTable in which, when I edit a cell and I push a keyboard button, a new Frame opens to edit the content of the cell.
But the problem is how to write something in the JTable cell, before setting its model. Because, I know, setCellAT() method of JTree inserts the value in the model and not in the table view. And repainting doesn't function!
What to do??
ThanksHi there
Depending on your table model you should normally change the "cell value" of the tablemodel.
This could look like:
JTable table = new JTable();
TableModel model = table.getModel();
int rowIndex = 0, columnIndex = 0;
model.setValueAt("This is a test", rowIndex, columnIndex);
The tablemodel should then fire an event to the view (i.e. JTable) and the table should be updated.
Hope this helps you -
How to write a composite element in iterator?
Hi,
I want to write a composite element in iterator which has the same result as BSP element like this in BSP layout:
<htmlb:link id = "link1"
reference = "http://www.sap.com">
<htmlb:textView id = "text1"
textColor = "<%=gv_color%>"
text = "ddddd" />
</htmlb:link>
Do you know how to write this in iterator? Thanks!Hi,
you can use the replacement bee:
data: o_link TYPE REF TO cl_htmlb_link.
CASE p_column_key.
WHEN 'column_name'.
w_event = model->get_sapevent_string(
name = 'activity'
system = 'crm'
key = o_ref->guid ).
o_link = cl_htmlb_link=>factory( id = p_cell_id
text = 'text'
tooltip = 'tooltip'
reference = w_event ).
p_replacement_bee = o_link.
ENDCASE.
in w_event you declare your event, eg. the calling of a
sap event or you navigation.
you can find an example in:

Why and how to use events in abap objects
Dear all,
Please explain me why and how to use events in abap objects with real time example
regards
pankaj giriHi Pankaj,
I will try to explain why to use events... How to use is a different topic.. which others have already answered...
This is same from your prev. post...
Events :
Technically speaking :
" Events are notifications an object receives from, or transmits to, other objects or applications. Events allow objects to perform actions whenever a specific occurrence takes place. Microsoft Windows is an event-driven operating system, events can come from other objects, applications, or user input such as mouse clicks or key presses. "
Lets say you have an ALV - An editable one ...
Lats say - Once you press some button you want some kind of validation to be done.
How to do this ?
Raise an Event - Which is handled by a method and write the validation code.
Now you might argue, that I can do it in this way : Capture the function code - and call the validate method.
Yes, in this case it can be done.. But lets say .. you change a field in the ALV and you want the validation to be done as soon as he is done with typing.
Where is the function code here ? No function code... But there is an event here - The data changed event.
So you can raise a data changed event that can be handled and will do the validation.
It is not user friendly that you ask the user to press a button (to get the function code) for validation each time he enters a data.
The events can be raised by a system, or by a program also. So in this case the data changed event is raised by a system that you can handle.
Also, Lets say on a particular action you want some code to trigger. (You can take the same example of validation code). In this case the code to trigger is in a separate class. The object of which is not available here at this moment. (This case happens very frequently).
Advantage with events : Event handlers can be in a separate class also.
e.g : In the middle of some business logic .. you encounter a error. You want to send this information to the UI (to user - in form of a pop up) and then continue with some processing.
In many cases - A direct method call to trigger the pop up is not done. Because (in ideal cases) the engine must not interact with UI directly - Because the UI could be some other application - like a windows UI but the error comes from some SAP program.
So - A event is raised from the engine that is handled in the UI and a pop up is triggered.
Here -- I would have different classes (lets say for different Operating Systems). And all these classes must register to the event ERROR raised in application.
And these different classes for different Operation systems will have different code to raise a pop-up.
Now you can imagine : If you coded a pop-up for Windows (in your application logic) .. it will not work for Mac or Linux. But of you raise a event.. that is handled separately by a different UI classes for Win, Linux or Mac they will catch this event and process accordingly.
May be I complicated this explanation .... but I couldn't think of a simpler and concrete example.
Cheers.

Writting Events for TableView Buttons
Hi SDN,
I created a table view in a jsp dynpage which has one of the columns type as button.i got it by using "setColumnType" attribute of tableview.
now i want to fire server and client events onclick of those buttons.how to achieve it? can we write client and server events for those buttons as like normal buttons.
if yes tell me how and where to write?
explain me with example (coding) if possible.
Thanks & Regards,
Art.
/points will be rewarded/Hi Subathra,
Thank you for ur reply.i know that we can achieve it using "setOnCellClick " but i want to know whether we can use the normal attributes of a button for this button placed in a cell of a tableview.
if yes how to use it.is there any relation between cell renderer attribute and my requirement.
<b><u>Note:</u></b>
you can share ur ideas about other components also which can be used in a tableview (inputfield,link,image...) and writting events for those components.
Thanks & Regards,

How to write to file Unicode characters
I have PDF files that I need to copy some strings out of and put them in various fields in a Postgres database. The goal is a Java screen into the database, whiere I mark and copy the PDF text and then paste it into a field in a Swing window, and from there into the database.
I am unsuccessful at reading a PDF file, so I have opted to cut and paste the PDF file into an MS word file. This results in errors in certain unicode characters. I am trying to rectify them by a simple program, a start of which is below, by a replacement of the erroneous char by the proper unicode symbol. As, shown by the following, I cannot figure out how to write out a unicode character. Do I need to wrap (which I don't know much about yet)? Or do I have a file problem? (I have a Vista machine.) I don't think it should be impossible to write unicode into a file, as I am able to write into MS Word files phonological symbols, Russian, and Sanskrit. So, it must be in the java.
P.S.: I am reading Schildt's Java: A Beginner's Guide and am through chapter10, but remaining chapters are on threads, enumerations, autoboxing, static import, annotations; generics,; applets, events, and miscellaneous topics, and, finally Swing. Maybe its in the autoboxing?
Any help would be most appreciated.

How to get event from message?
Hi,All:
I write a run-time interface by CVI, I use TS_EngineRegisterUIMessageCallback to register my callback function, but when message passed to the callback function, as the type is struct IDispatch but not CAObjHandle, I don't know how to read event from message.
Can you help me to solve it? Thanks
Chang ZhangHello Chang-
If your question is simply how to obtain an object handle from an object of type IDispatch, have you investigated the function "CA_CreateObjHandleFromIDispatch"? I would recommend you look over the testexec.prj that is installed along with the TestStand engine (the CVI Operator Interface) and inspect how we handle our callbacks, this may help you understand how to go about emulating the behavior in your own project. To see this particular function in use it may be most helpful to look in the file 'engine.c' and inside the function UIMessageDeferredCallback here you will see the IDispatch pointer being handled and decoded for use by the TS engine.

Anyway, now that you've posted that code, what is your question about it? I see you are calling a "getAvailableFontFamilyNames" method; do you have a question about that? If so, what is the question? -

How to customize events, execute stored procedures using JSF and ADF BC
As a java beginner, I started with developing simple web application using JSF and ADF business component through visual and declarative approach. I need to know how to customize events, execute stored procedures, invoke functions on triggering events associated with rich controls. for eg. how to write customized functions on button click or checkbox click events to achieve business requirement and can be modified whenever required.
Edited by: 792068 on Aug 31, 2010 9:40 PMWhich business layer is prefered to create interactive data model: 1. ADF business components or 2. Enterprise JavaBeans using Java persistance API (JPA) or 3. Toplink 4. Portlets
which minimizes writing low level codes and how much OOPS knowledge is required for creating above business layer binding data to viewcontroller layer? -
How to write Error message for select options?
Hi
i have this select option statement
SELECT-OPTIONS: s_fevor FOR afko-fevor.
how to write error message for this?
Regards
SmithaError messages are displayed for Select-options mostly on two conditions:
1) You needs to check wether a value is entered or not its done by:
a)
Select-options:SELECT-OPTIONS: s_fevor FOR afko-fevor Obligatory.
In this case error message is automatically throwed by system.
b) You can do this in Selection Screen events.
Ex:
AT SELECTION-SCREEN./AT SELECTION-SCREEN ON S_FEVOR.
IF S_FEVOR-LOW IS INITIAL.
MESSAGE 'XXXXX' TYPE 'E'.
ENDIF.
2) You need to Validate the entered value:
You can do this in Selection Screen events.
Ex:
AT SELECTION-SCREEN./AT SELECTION-SCREEN ON S_FEVOR.
SELECT FEVOR
FROM AFKO
INTO AFKO-FEVOR
UP TO 1 ROWS
ENDSELECT.
IF SY-SUBRC NE 0.
MESSAGE 'XXXXX' TYPE 'E'.
ENDIF.
