OOPs alv

[Former Member]

hi..

iam new in OO ABAP. Please solve my doubts. points will be rewarded for good answers.

1. what is the usage of cl_gui_splitter_container, cl_gui_docking_container? how is it different from custom contianers and in which situation we opt for those 2 containers.?

2. what is the use of refresh_table_display in oops alv? actually in what situation we will use it?

3. Can we use ONE container to display different lists? ie. if iam coding an interactive oops alv report, can i use the same container to display basic list and also secondary list?

thanks,

hi ,

there is an example for the cl_gui_splitter_container some where i had used.

Separation line invisible (guess in this case it is also unmovable)

code CALL METHOD splitter->set_column_sash

EXPORTING

id = 1

type = cl_gui_splitter_container=>TYPE_SASHVISIBLE

value = cl_gui_splitter_container=>false

IMPORTING

RESULT =

EXCEPTIONS

CNTL_ERROR = 1

CNTL_SYSTEM_ERROR = 2

others = 3.[/code]

Separation line visible yet unmovable

code CALL METHOD splitter->set_column_sash

EXPORTING

id = 1

type = cl_gui_splitter_container=>TYPE_MOVABLE

value = cl_gui_splitter_container=>false

IMPORTING

RESULT =

EXCEPTIONS

CNTL_ERROR = 1

CNTL_SYSTEM_ERROR = 2

others = 3.[/code]

here is the example for the docking container.

the docking container into two parts, buttom is the text editor, the top is our toolbar, notice the only button there is Print, if you click this this will fire an event and will write out what you have typed into the text editor control.

code

report zrich_0001.

type-pools: icon.

data:

dock_sub_cont1 type ref to cl_gui_container,

dock_sub_cont2 type ref to cl_gui_container,

text_editor type ref to cl_gui_textedit,

Hi

The below link will give you the brief idea about the usage of Splitter, Docking and Custom Container and the supported methods. With this we can find out the difference between these also.
