How to define event hander interface in Class Builder (se24)?

Hello,
I've got the following local interface defined.
INTERFACE lif_alv_grid_event_handler.
METHODS:
    handle_button_click FOR EVENT button_click OF cl_gui_alv_grid
      IMPORTING es_col_id es_row_no,
    handle_double_click FOR EVENT double_click OF cl_gui_alv_grid
      IMPORTING e_row e_column es_row_no,
    handle_hotspot_click FOR EVENT hotspot_click OF cl_gui_alv_grid
      IMPORTING e_row_id e_column_id es_row_no,
    handle_toolbar FOR EVENT toolbar OF cl_gui_alv_grid
      IMPORTING e_object e_interactive,
    handle_user_command FOR EVENT user_command OF cl_gui_alv_grid
      IMPORTING e_ucomm.
ENDINTERFACE.
Now I want to define it as a dictionary object using se24.
My problem is I could not find the quivalent of "FOR EVENT"
word in it.
Is there any chance to do that in Class Builder?
Best regards
Pawel

Hello Pawel
Display your class with the event handler methods in SE24 / SE80 and choose the DETAIL button (above the table control with the methods).
Here you can define a method as "event handler for" an event of another class.
On SAP release >= 6.20 you can right-click on a method in the tree view and choose context menu function Display -> Definition (tabstrip Attributes ).
Regards
Uwe

How to assign the events in a specific method in class builder(se24)

i have declared one event in event part.i want to asign the event to one method .can any one help me .i have to do it in se24.pls

hi,
create a class in se24.
click the EVENTS tab, define an event.
click the METHODS tab, define a method to trigger/ raise the event
define one more method as an event handler method for the event.
for a method to be an event handler, click on the detail view,
select the check box Event Handler for give the classname where the event is defined and the event name, click on Change button.
event can be in the same class or different from that of the event handler method.
don't forget to register the event handler method in the program.
click the code button of ur trigger method(meth2 in my example) and write there,
raise event evt1.
now your class is ready.
now in se38 program,
declare a reference variable to ur class,
create an object,set the handler for ur event,
call the trigger method
data:oref type ref to zsowcl1.
create object oref.
set handler oref->meth1 for oref. handler method
call method oref->meth2. raise evnt method
hope it gives you clear idea,
Regards,

Forward Declaration in Class Builder

Hi All,
In the Class Builder (SE24)when i create a new Class, There is an option of Forward declaration in the Property Tab. In this, we can add Type Group Interface and Class. What is the Purpose of this forward declaration?
The F1 help does not provide any help.
Regards,
Kapil.

in addition to above replies, it can be used for classes and interfaces in that case Forward declaration is equivalent to
CLASS <class_name> DEFINITION LOAD.
interface <interface_name> load
statements which are normally used in Program ( case for local classes )
use of Load from SAP docu
... LOAD
Effect
The variant with the LOAD addition loads a global class class from the Class Library. This statement was needed before Release 6.20 if you wanted to access one of the static components of class from within a program, or to declare an event handler for class before class had been loaded automatically. From Release 6.20 onwards, the LOAD addition is only needed if the compilation of an ABAP program fails because it includes recursive accesses of a globa l class. In such cases, you may be able to make the program compilable by explicitly loading the class before recursion.
Thanks,
kranthi.

To use logical database PNP in class builder

Hi
Inside the class builder (SE24), i have a created a method.
Now while implementing that method, that is between method and endmethod
statement can i implement logical database PNP or PNPCE.
If 'yes' how to use it.
if 'no' what is the other way to implement authorization.
Pls help me

Hello,
assume that the routines GET_ITnnnn are written by yourself. For reading infotypes ABAP Objects provides us with same very helpful classes as shown below:
* define data
DATA:
 gif_employee type ref to if_pt_employee,
 go_employee type ref to cl_pt_employee,
 gt_infotypes TYPE tim_tmw_itlist_tab,
 go_control TYPE REF TO if_pt_td_control,
 go_data TYPE REF TO if_pt_td_base,
 go_pnnnn TYPE REF TO if_pt_td_itnnnn,
 gt_p0001 TYPE TIM_P0001_TAB,
 gt_p0002 TYPE TIM_P0002_TAB,
 gt_p0003 TYPE TIM_P0003_TAB.
start-of-selection.
GET pernr.
* Create employee instance
gif_employee = cl_pt_employee=>get_employee( pernr ).
go_employee ?= gif_employee.
* Get master infotypes (0001, 0002)
CALL METHOD go_employee->get_master_data
 EXPORTING
 im_begda = id_fromdate
 im_endda = id_todate
 IMPORTING
* EX_I0000 =
 EX_I0001 = gt_p0001
 EX_I0002 = gt_p0002
* EX_I0007 =
* EX_I0008 =
* Append all other required infotypes to itab
APPEND '0003' TO gt_infotypes.
CALL METHOD go_employee->get_infotypes
 EXPORTING
 i_itlist = gt_infotypes
 i_fromdate = id_fromdate " start date
 i_todate = id_todate " end date
* I_FILTER =
 i_noauthcheck = 'X'
 IMPORTING
 e_result = gt_infty_request
 e_retcd = gd_retcd.
* Please see documentation of parameter e_retcd...
LOOP AT gt_infty_request INTO go_control.
 go_data = go_control->data. " get data object
* Casting
 TRY.
 go_pnnnn ?= go_data.
 CATCH cx_sy_move_cast_error.
 CONTINUE.
 ENDTRY.
* Convert infotype (semi-transparent -> transparent)
 CALL METHOD cl_hr_pnnnn_type_cast=>prelp_to_pnnnn
 EXPORTING
 prelp = lo_pnnnn->prelp
 IMPORTING
 pnnnn = gs_p0003.
 APPEND gs_p0027 TO gt_p0003.
ENDLOOP.
The class CL_PT_EMPLOYEE provides us already with very easy access to so-called master infotypes (000, 0001, 0002, 0007 and 0008). All other infotypes can be read using method GET_INFOTYPES.
Using these classes we have a very convenient and standardized way of accessing all kinds of infotypes.

OO ABAP - Retrieve source from Class Builder?

Hi. Is there a way to display the source code for a class or interface definition that was created with the class builder (se24).
I looked through the drop downs, but I didn't see anything to display the source.
Thanks in advance.
Brendan

A class is distributed upon several includes. The Se24 in my 45b system offers to view the source via button on the bottom of the method list.
If you like you can try the following sample program also. Just paste the source and create the Pf-Status 'STA_MAIN' (line 135) and add the commands PICK(f2),Back, Exit, My_Edit(any key).
PS: double clicking on a include navigates forward ( if PICK is set to F2 ).
PPS: If you experience trouble with pasting the code and lost line termination, please paste into wordpad an save as text file.

Very Urgent: how to define field symbols in class using se24 Points assured

hi all
I am new to abap oo programming. I am using se24 to build a class
where some methods have code which involves working with field sybmols but i am not able to figure out way for how to define field symbols in the attributes section.
I tried defining like : fld_sym type ref to dbtab-fld
but in the method implementation if i try to use it like assign fld to <fld_sym> there it says fld_sym is not defined as a field symbol.
So can anyone please guide me how to define field symbols in se24.
Also what should be the general steps while creating a class using se24.
Points assured
thanks

Hi
Global classes are like Global fun modules in which the Methods and code is already written and is mainly used for Reusability purpose.
Goto SE24 tcode and see the std global classes like

To change the string in Class Builder "New Method"

HI friends,
Im using the std program of "RFDOPR10"...(changed into my customised program as ZRFDOPR10).....
Here i want to change the strings of Id_type eq 4 availble under the class builder "New Method".
"id_ruler_string = '2.13.24.29|43|58|73|88|103|118|'" (for 24...i want to give 38.....then 45...)
Pls help me how to change the std method function for my z program...
FYR:
RFDOPR10 is the std program for tcode :"s_alr_87012178", Customer analysis.If u want to c the example report, in this tcode...give OI:1, Summ level:6, OI list:1 and Company CD:2 under Output control tab in selection screen with Company code.Now, u able to see the reports in the screen.There, after Customer number....I've to give some more spaces(length) for Sort field.
Thanks & regards

No, but I suggest using a different editor which does allow a different text option and just pasting it in.

Associated with the text box there will be some kind of event handler. Maybe it's an action event on the text box (when the user clicks return) or maybe you have a separate button that the user clicks.
Either way, in the event handler, get the text from the text box, and then call the sendData method, passing the text as an argument.
