Using protected events

can any one give example program to use protected events from standard class cl_gui_alv_grid using local class in z reports.

Hi parimi,
Check this link, this will help you to get some idea.
Here using protected event CLICK_ROW_COL is explained.

How to use Protected event CLICK_ROW_COL of cl_gui_alv_grid.

I've worked with Double_click,Hotspot_click events of Cl_gui_alv grid class quite comfortable as they are Public.
But i'm unable to work with click_row_col..
Could u tell me how to use protected event click_row_col..

Hi Ilayarajaramana
Did you try to build up a subclass of cl_gui_alv_grid and access the protected events via the subclass?
You could e.g. throw an own public event every time the click_row_col event is risen.
I know this isn't the best way, but it should work.
Kind Regards,
Sebastian

Use of Events in OOPS ABAP

Hi all,
Can anybody please say me what is the exact use of EVENTS in OOPs ABAP. Can anybody please explain me with an example.
Thanks in advance.

hi,
By triggering an event, an object or a class announces a change of state, or that a certain state has been
achieved.
Events link objects or classes more loosely than direct method calls do. Method calls establish precisely
when and in which statement sequence the method is called.
However, with events, the reaction of the
object to the event is determined by the triggering of the event itself.
Events are most often used in GUI implementations.
Other external object models, such as COM, ActiveX Controls etc, also provide events.
At the moment of implementation, a class defines its
instance events (using the statement EVENTS) and
static events (using the statement CLASS-EVENTS)
Classes or their instances that receive a message when an event is triggered at runtime and want to react
to this event define event handler methods.
Statement : (CLASS-)METHODS <handler_method> FOR EVENT <event> OF <classname>.
These classes or their instances register themselves at runtime to one or more events.
Statement : SET HANDLER <handler_method> FOR <reference>. (for instance events)
SET HANDLER <handler_method>. (for static events).
A class or an instance can trigger an event at runtime using the statement RAISE EVENT.
Both instance and static events can be triggered in instance methods.
Only static events can be triggered in static methods.
Events can only have EXPORTING parameters which must be passed by value.
Triggering an event using the statement RAISE EVENT has the following effect:
the program flow is interrupted at that point
the event handler methods registered to this event are called and processed once all event handler methods have been executed, the program flow starts again.
If an event handler method in turn triggers an event, then the program flow is again interrupted and all event handler methods are executed (nesting).
Events are registered using the command SET HANDLER. Registration is only active at program runtime.
Events cannot be persistent.
You want to register an object to an event belonging to another object. The SET HANDLER... statement
enters the registration in that objects list. All handlers for one event are entered in this list.
When the event is triggered, the list shows which event handler methods need to be called.
Event handler methods are triggered by events (RAISE EVENT), although they can also be called like
normal methods (CALL METHOD).
The interface of the event handler method consists solely of IMPORTING parameters. Only parameters
from the definition of the corresponding event (event interface) can be used.
An event interface only has EXPORTING parameters and is defined using the EVENTS statement in the declaration of the event. The
parameters are typed in the event definition and the typing is passed to the event handler method, that is,
the interface parameters of the event handler method cannot be typed in the definition of the event handler
method.
In addition to the explicitly defined event interface parameters, the implicit parameter SENDER can also be
listed as an IMPORTING parameter for instance events. This passes on a reference to the object that
triggered the event.
Events are also subject to the visibility concept and can therefore be either public, protected or private.
Visibility establishes authorization for event handling :
all users only users within that class or its subclasses
only users in that class.
Event handler methods also have visibility characteristics. Event handler methods, however, can only have
the same visibility or more restricted visibility than the events they refer to.
The visibility of event handler methods establishes authorization for SET-HANDLER statements: SET
HANDLER statements can be made anywhere in that class and its subclasses only in that class

ALV access protected event click_row_col ?

Hi All,
Could anyone give a sample code as to how I can access the ALV protected event "click_row_col" ?.
I am trying to get an event to trigger to validate (select only 1 checkbox per row) after user checks on a checkbox on the alv grid display.
Thankss,
Neeth

Hi Nameeth
Or do you want to select the row whose checkbox field is checked. Then, at the data_changed event you can use the method "set_selected_rows" .

Can we use control events in smartforms

Hi all,
I am srinivas. can we use control events in smartforms, I mean at new, at end of ..... if these are not used can you suggest me any alternative....
Actually my requirement is like a classical report, for which I need to display subtotal and grand totals based on two fields....

Hi Nick,
 Thanks for the reply... it is really very useful for me.
As I discussed in my earlier mail regarding the output sequence, which should be in the below format.
 number quantity uom unitprice amount curr
plant
 material
 date
 x y z A
 e f g h
 p q r s
 subtotal date..... 1 2 3 4
 subtotal material.5 6 7 8
As you said when I using event of Begin its working fine. but while using the event of end, I am specifying date and then matnr (sort) its taking(nodes are created mean first matnr and then date) in the reverse order and when I am taking matnr and date it is placing the events(nodes) in the right order but the order date is not triggering.
can please tell me how to proceed here..
waiting for your reply..

Can we use Initilization event in module pool program?

Hi All,
Can we use Initialization event in module pool program? If not why?
Thanks In Advance!!!!!!!!!

The runtime environment creates the INITIALIZATION event and calls the corresponding event block (if it has been defined in the ABAP program).

How do I use the event.target.name String with an external dispatchEvent?

...I hope the title question makes sense...
On my stage I have an externally loaded SWF with a button. When clicked the button dispatches an event to the main stage.
On the main stage a listener then loads an SWF into a loader called gallery.
The gallery loader is also being shared by buttons on the main stage which use the event.target.name String to call in SWFs with corresponding names.
I am using Tweens to fade-out and -in content to the gallery when a button is pressed.
Loading the SWFs was working until I tried to create a universal button function for the dispatchEvent buttons...
The problem I have is that I don't know how to define the String to tell the newSWFRequest where to find the SWF when triggered by the external buttons.
(I may be doing this all wrong... but figured the best way to load an SWF on to the main stage from an external SWF was by using dispatchEvent??)
My code triggers the Event and the gallery loader fades out, but then it cannot find the new SWF:
Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
Please can someone help me understand the way to make the String point in the right direction? (I think the only errors are in bold below)
Code:
var myTweenIn2:Tween;
var myTweenOut2:Tween;
var nextLoadS2:String;
// Listen for external event dispatched from external btns
addEventListener("contactStage", btnClickExtrnl);
function btnClickExtrnl(e:Event):void {
nextLoadS2 = ?????
myTweenOut2=new Tween(gallery,"alpha",None.easeOut,gallery.alpha,0,0.2,true);
myTweenOut2.addEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteF2);
// Btns Universal function
function tweenOutCompleteF2(e:TweenEvent){
myTweenOut2.removeEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteF2);
myTweenOut2=null;
    var newSWFRequest:URLRequest = new URLRequest("swfs/" + nextLoadS2 + ".swf");
myTweenIn2 = new Tween(gallery, "alpha", None.easeOut, gallery.alpha, 1, 0.2, true);
    gallery.load(newSWFRequest);
    gallery.x = Xpos;
    gallery.y = Ypos;
Thank you.

That works – thank you!
I'm now using this code to fade in each of the SWFs:
function contactStage(e:MouseEvent):void {
    var newSWFRequest:URLRequest = new URLRequest("swfs/"+e.currentTarget.name+".swf");
    myTweenIn = new Tween(gallery, "alpha", None.easeOut, 0, 1, 0.2, true);
    gallery.load(newSWFRequest);
    gallery.x = Xpos;
    gallery.y = Ypos;
But I cannot add the fade out function. I have amended the above code to create:
var myTweenOutX:Tween;
var myTweenInX:Tween;
function contactStage(e:MouseEvent):void {
myTweenOutX=new Tween(gallery,"alpha",None.easeOut,gallery.alpha,0,0.2,true);
myTweenOutX.addEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteFX);
function tweenOutCompleteFX(e:TweenEvent){
myTweenOutX.removeEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteFX);
myTweenOutX=null;
    var newSWFRequest:URLRequest = new URLRequest("swfs/"+e.currentTarget.name+".swf");
myTweenInX = new Tween(gallery, "alpha", None.easeOut, 0, 1, 0.2, true);
    gallery.load(newSWFRequest);
    gallery.x = Xpos;
    gallery.y = Ypos;
But get this error:
ReferenceError: Error #1069: Property name not found on fl.transitions.Tween and there is no default value.

How to schedule a background job using the Event concept..?

Hi Folks,
I have a requirement that, I need a schedule a background job.
Once after the previous job successful only, new job should get triggered. How to go ahead with this..?
For Eg, I am scheduling a job called ZTEST periodically for 1 minute. If the job is not get completing with in 1 minute, I dont want to start my new job. Only after the success of my old job, I want my new job to run.
Waiting for ur replies.
Regards,
Savi.

Hi,
You can use events that have already been defined, or you can create new events for scheduling background jobs.
If you wish to use new events, do the following to implement the event scheduling:
Define and transport the event as a user event with transaction SM62.
You must define only event IDs; event arguments are not defined in the R/3 System. Instead, you specify event arguments when you schedule a job to wait for an event and when you trigger the event.
If you define a new event, you must also transport it to your production systems. The event transaction does not have a connection to the transport system. Instead, you must create a transport request for the event yourself.
Do this to transport an event:
Create a transport request.
Start the editor in the transport request and enter the following:
R3TR TABU <table name> where table name is BTCSEV for a system event ID, BTCUEV for a user event ID.
Press F2 with the cursor on the table name to call up the screen for specifying the table entries to transport. In this screen, enter the event IDs that you have created.
Save and release the transport request. Ensure that it is imported into your production system(s).
To trigger an event, add:
the function module BP_EVENT_RAISE to your ABAP program, or
the program SAPEVT to your external script, batch file, or program.
When your programs execute these keywords, an event will be triggered in the R/3 background processing system. The event-based scheduler is started immediately. It in turn starts all jobs that were waiting upon the event, subject to normal background processing restrictions, such as the requirement that the job has been released to start.
Schedule the jobs that are to run when your events are triggered.
You can schedule jobs for one-time start or to be started whenever an event is triggered.
Regards,
Raj.

How to use multiple events on one project?

I want to make a show reel, this obviously involves using various events.
I'm worried if I do this the whole file system will be a mess. Surely I should be sopying any files I want to use into the new showreel folder?
How can i do this?
Or is using various events ok?
Hope someone ca recomend the best way forward

You can edit from any event into the project. There is no need to copy the clips into a new event. When you're done you can archive the used clips into a new event.

Using Multiple Event Listeners

Hi,
I have a movielcip (A) class in which I have used a Tween class effect on a child movieclip (B) scrollRect. The (B) Movieclip in turn has several movieclips whose have tween class effect being executed on thier child movieclips.
the tweens are all unique to each movieclip
and the event listeners are taken off once completed.
This works all well and good in FLASH IDE...
My problem arises when I try to view this in a browser on a Windows XP
it doesnt work in
Opera Version 9.63
Firefox 2.0
and Google Chrome 2.0
The only browser it works fluently in is
Internet Explorer 7.0.5
What is happening in most cases it that the animation appears to "stick" but i think what may be happening is the listening or removal of the event listeners. The animations are left incompleted.
Is there any rule of thumb when using multiple event listeners?
here is a snippet of some of my code
on click event from movieclip (A)
private function scrollToSlidePrev(e:MouseEvent) {
               if (((slideIndex - 1) >= 0)) {
                    nextButton.mouseEnabled = nextButton.enabled = previousButton.enabled = previousButton.mouseEnabled = false;
                    var position:Number = 0-SLIDEAREA.width;
                    var slide1:TileListSlide = slides[slideIndex] as TileListSlide;
                    var slide2:TileListSlide = slides[--slideIndex] as TileListSlide;
                    scrollSlide(position,slide1,slide2);
tween animation in movieclip (A) on (B)
private function scrollSlide(pos:int,slide1:TileListSlide,slide2:TileListSlide) {
               slide1.resizeSlideTo(0.6); // execute tween on child movie clips in B
               slide2.resizeSlideTo(1); // same as above;
               var rect:Rectangle = sliderMc.scrollRect;
               var tween1:Tween = new Tween(rect,"x",Regular.easeOut,rect.x,rect.x + pos,3,true);
               tween1.addEventListener(TweenEvent.MOTION_CHANGE,setSliderScroll,false,4);
               tween1.addEventListener(TweenEvent.MOTION_FINISH,toggleButtonEnabled,false,3);
tween animation in movieclip (B) children
public function resizeSlideTo(sc) {
               var m:Matrix = tileList.transform.matrix as Matrix;
               var p:Point = new Point (m.a, 0);
               var tween2:Tween = new Tween(p,"x",Regular.easeOut,p.x,sc,3,true);
               if (numericStepper != null) {
                    if (sc != 1) {
                         numericStepper.visible = false;
                         tween2.removeEventListener(TweenEvent.MOTION_FINISH,showStepper);
                    if (sc === 1) {
                         tween2.addEventListener(TweenEvent.MOTION_FINISH,showStepper,false,2);
               tween2.addEventListener(TweenEvent.MOTION_CHANGE,setScaleOnScroll,false,3);
here is the link
http://visual_admin.web.aplus.net/ticker/ticker_widget.html
the effect disables and re-enables the buttons when its done.... then the listeners are removed.
each one with the exception cretes its own unique tween (obviously this is a custom class built as each clip)
i really don't know what to make of it guys

apparantly making the tween a property of the class rather than a random variable in a function worked.....go figure

Which method is used for event creation

Dear All,
My client has more then one Purchase Organization. Workflow for Purchase order release very from pur org to pur org. For example - workflow WS92000030 is trigger when PO is created for India pur org where as workflow WS92000021 is trigger when PO is created for US pur org.
I checked and found that same Object Type - BUS2012 & event - RELEASESTEPCREATED is used in all Pur. Org PO release workflow. Also I found in Transaction code - SWETYP that Type linkage activate for BUS2012, RELEASESTEPCREATED in all the PO workflow - WS92000030 & WS92000021.
As per my knowledge, event can be created in various way such as Function module, Change document, General status management, Business Transaction Events etc.
Can some one guide me, how can I found that which method is used for event creation in different pur org?
How can I fould what is the fuctional module used for event creation if Fuctional module used for event creation.
For your information, I can see in T. Code - SWUO that 'Result dependent on a check function module' for all the workflow - WS92000030, WS92000021 etc.
Thanks in

Hi Sahu,
I dont think they have used the Function module or change document or any other kind of methods to trigger the workflow. This is because RELEASESTEPCREATED method is a standard method and it will be triggered by standard SAP. They can not make changes in standard sap saying RELEASESTEPCREATED should be triggered for this Purchase Org .
Istead what i think is, they might have given the Event Condition for each workflow.
In SWDD>> basic settings>> Start Events, we can give condition on triggering the workflow.
Please check this.
Regards,
Gautham

I have an iMac about a year old. It has OSX 10.8.3 with iMovie 9.0.8. Is there a way to get iMovie to store and use iMovie Events on an external drive? Raw video is eating up my 1TB internal drive.

I have an iMac about a year old. It has OSX 10.8.3 with iMovie 9.0.8. Is there a way to get iMovie to store and use iMovie Events on an external drive? Raw video is eating up my 1TB internal drive.

Yes, you can import to an external drive by choosing it from the Import Screen.
Once an Event or Project is in iMovie, it is best to move it to the external using iMovie, so the Project does not lose links to the Event.
For full instructions on how to do this, see this link.

How to use protect and endprotect in smart form

hi to all experts,
im still begineer in smart form , i have two headings like
company_code: purchase doc no:
after this i have a table to be displayed with four columns
what i want is the whole data should not be split by a page break
i know this can be achieved by using protect and end protect in sap scripts how to implement in smart form

probably u have the table inside a loop or a folder or something....
see this
Page protection attribute
Switch for page protection.
Use
Page protection switch.
In some cases you may want to avoid that text is divided by a page break. Therefore, you can protect text sections with a page protection.
Page protection can extend to
a paragraph
a text node
all output within a folder, for example, several text nodes combined in this folder.
a line type (table node)
If on the current page there is not enough space left for the protected text, it is displayed entirely on the next page.
So u can page protect a line in table...
in the table node..goto tables tab and click the details tab-->select the line type and check the 'no page break'
check box

How to use protected method in jsp code

Could anyone tell me how to use protected method in jsp code ...
I declare a Calendar class , and I want to use the isTimeSet method ,
But if I write the code as follows ..
========================================================
<%
Calendar create_date = Calendar.getInstance();
if (create_date.isTimeSet) System.out.println("true");
%>
============================================================
when I run this jsp , it appears the error wirtten "isTimeSet has protected access in java.util.Calendar"

The only way to access a protected variable is to subclass.
MyCalendar extends Calendar
but I doubt you need to do this. If you only want to tell if a Calendar object has a time associated with it, try using
cal.isSet( Calendar.HOUR );
