Hi Experts,

I am new to Object orientedABAP.

Can any body tell me how to call a built-in class and method in to my ABAP report with some example?

go to pattern and choose ABAP object patterns.

Enter object name,method name and class name.

To call object

You should simply look at one of the BCEDIT programs.

1. Create the object for the class

2. Call the method of the class using the object created. You can use the pattern button of the ABAP Editor.

Here is a example.

Hi Thanks.

Points are given.

Whare to create object for the class?

After creating object for that calss we need to call that method by clicking Pattern button?

You can create the object/instance of the class in the program (report / dialog program) where you want to make that call. Even the CREATE OBJECT also can be done using the pattern

Once that is done use the instnace name and the class name to get the pattern of the method.

Hi Ravi,

This is how u can create object!!

DATA: container TYPE REF TO cl_gui_custom_container,

tree TYPE REF TO cl_gui_simple_tree.

CREATE OBJECT container

EXPORTING

container_name = 'CUSTOM'.

IF sy-subrc <> 0.

MESSAGE e009(zvikalp).

ENDIF.

CREATE OBJECT tree

EXPORTING

parent = container

node_selection_mode = cl_gui_simple_tree=>node_sel_mode_single.

IF sy-subrc <> 0.

MESSAGE e014(zvikalp).

ENDIF.

Other than this u also need to register events. and define the calss in the top include as shown-

----

CLASS lcl_tree DEFINITION

----

........ *

----

CLASS lcl_tree DEFINITION.

PUBLIC SECTION.

CLASS-METHODS : catch_dbl FOR EVENT node_double_click OF

cl_gui_simple_tree IMPORTING node_key.

ENDCLASS.

----

CLASS lcl_tree IMPLEMENTATION

----

........ *

----

CLASS lcl_tree IMPLEMENTATION.

METHOD catch_dbl.

g_event = 'NODE_DOUBLE_CLICK'.

g_node_key = node_key.

ENDMETHOD.

ENDCLASS.

Hope this helps u.

Regards,

Seema.

hi,

Tcode -> SE24. Give the class name cl_http_client->

Display. You will find a list of methods that are implemented in that class.

call method cl_http_client=>create_by_url

exporting

url = wf_string

importing

client = http_client

exceptions

argument_not_found = 1

plugin_not_active = 2

internal_error = 3

others = 4.

create_by_url is a STATIC method. So, we used => as operator. If we want to access INSTANCE methods, we have to use -> operator.

Sailaja.

Hi Ravi,

In Object Oriented There is you 1st make local class define all the and then implement event in it than in PBO set handler. and the class is:

Classes describe objects. From a technical point of view, objects are runtime instances of a class. In theory, you can create any number of objects based on a single class. Each instance (object) of a class has a unique identity and its own set of values for its attributes.
