general issue with class declaration

[Former Member]

Hi all,

Iam very new to OO programming.

can any one tell as how i should call a CLASS

FOR FM , i know we use click pattern and give the required FM name and it would bring up the code in the editor and we have to pass the necessary parameters

but how should i call a class , is there a way to call it or do i need to write the code manually

say when i code like this does that mean it has been typed or just called like a FM

If its called like FM , let me know how its called

CALL METHOD cl_gui_frontend_services=>file_open_dialog

EXPORTING

window_title = 'Select file for download'

default_extension = '.txt'

initial_directory = 'C:\'

CHANGING

file_table = li_filetable

rc = lv_return

EXCEPTIONS

file_open_dialog_failed = 1

cntl_error = 2

error_no_gui = 3

OTHERS = 4

.

Thanks

Hi,

You can use pattern (SE38) same as FM.

But instead choose ABAP Object Pattern -> OK -> Select Call Method -> Enter CL_GUI_FRONTEND_SERVICES (Class/Interface) -> Enter FILE_OPEN_DIALOG (Method) -> OK.

Hi,

You can use the pattern for abap oo class method also..

Press the pattern button..

Choose the radio button "AABAP Objects patterns"

Give the class name and the method name..It will give the parameters like FM..

Hi,

Sorry ... I am in SAP 4.7 and ECC 5.0.

I am not sure whether is available in 4.6C (i am afraid you need to type by yourself).

When you click on Pattern button (SE38), system should display an option for AABAP Object Patterns (4.7) and ABAP Object Patterns (ECC 5.0).

Then you click on OK button in order to see another selection for OO Statement Pattern (new popup window). In here, you should see Call Method selection and others.
