Posted: Sat Sep 08, 2007 12:02 am Post subject: Top of Page in ALV(OOPS)
Author: J.Jayanthi
Description:
This document describes how to
display picture in top-of-page
display url in top-of-page
display text in top-of-page
in ALV using OOPS method.
This document uses Splitter concept to split the container and then displays top-of-page in top container and output in bottom container by placing the grid inside the container.
Procedure
Step 1: Create a Docking container. Then create a splitter by taking the docking container as parent.
Data : o_docking type ref to cl_gui_docking_container,"Docking Container
o_split type ref to cl_gui_easy_splitter_container."Splitter
CREATE OBJECT o_docking
EXPORTING
RATIO = '95'.
IF sy-subrc eq 0.
* Splitting the Docking container
CREATE OBJECT o_split
EXPORTING
PARENT = o_docking
sash_position = 14 "Position of Splitter Bar (in Percent)
with_border = 0. "With Border = 1 Without Border = 0
ENDIF.
Step 2: Make the two containers so that one will be placed in top of split and the other in bottom. Create the grid so that it should be inside the bottom container. Create a object for class cl_dd_document so that text, url and images can be placed inside top of page.
Data : o_top_container type ref to cl_gui_container, "Top Container
o_bottom_container type ref to cl_gui_container,"Bottom Container
o_document type ref to cl_dd_document. "Document
* Placing the containers in the splitter
o_top_container = o_split->top_left_container .
o_bottom_container = o_split->bottom_right_container .
* Creating Grid
CREATE OBJECT o_grid
EXPORTING
i_parent = o_bottom_container.
* Creating the document
CREATE OBJECT o_document
EXPORTING
style = 'ALV_GRID'.
Step 3: Add the text, url and images by using o_document.
* Calling the methods for dynamic text
CALL METHOD o_document->add_text
EXPORTING
text = 'No. of Materials:'.
* Adding GAP
CALL METHOD o_document->add_gap
EXPORTING
width = 10.
* Adding Text
CALL METHOD o_document->add_text
EXPORTING
text = v_cln."V_cln is the variable holding no. of materials
* Adding Line
CALL METHOD o_document->new_line.
To add picture to the top of page, we need to find the picture id. We can find this by using tcode OAOR. Give Class name as PICTURES and Class TYPE as OT in selection.
Choose some picture inside that and in bottom click Details tab to get the ID.
* Adding Picture
CALL METHOD o_document->add_picture
EXPORTING
picture_id = 'TRVPICTURE01'
width = '100'.
* Adding Line
CALL METHOD o_document->new_line.
* Adding Links
CALL METHOD o_document->add_link
EXPORTING
name = 'OOPS Link'
url =
'https://forums.sdn.sap.com/forum.jspa?forumID=236'
tooltip = 'ABAP Objects Forum'
text = 'ABAP Objects Forum'.
* Display the data
CALL METHOD o_document->display_document
EXPORTING
parent = o_top_container.
* Calling the method of ALV to process top of page
CALL METHOD o_grid->list_processing_events
EXPORTING
i_event_name = 'TOP_OF_PAGE'
i_dyndoc_id = o_document.
Complete Code
Screen 9000, GUI Status ZSTATUS and GUI Title ZTITLE should be created and in Flow logic of the screen, PBO and PAI should be uncommented.
