SAPTLIST_TREE_CONTROL_DEMO

In the SAPTLIST_TREE_CONTROL_DEMO there is an property of an item usebgcolor which makes the items grey when set to 'X'. If I run this example on my computer, only the item 'SAPTROX1', node_key 'new3' item name '1' appears in grey. Other computers on other systems from collegues display all items in grey, because it's written in the code, every item has the usebgcolor set to 'X'.
The question is:
Why is only the SAPTROX1-item grey on my computer, a college on the same system has the same output. If it would be a question wether display colors are set or not, wouldn't every item appear (or not at all) in a different color??
This is a complete mystery for me.
If this question is solved, you can provide me with the help for setting the background color for an item of the list_tree_control to green, to display all items of a node in this color...
Could this be a sapgui problem? We are here on 710 Final Release, 7100.1.1.1028, Build 898946, Patch Level 1.

Problem: SAPTLIST_TREE_CONTROL_DEMO

Hi all,
right now i m working with SAPTLIST_TREE_CONTROL_DEMO program.
now the problem is that, i have an internal table which have multiple records, now i want to print all records in internal table through
INCLUDE TLIST_TREE_CONTROL_DEMOF01
my code is look like :
LOOP AT I_FINAL.
CLEAR ITEM.
item-node_key = c_nodekey-new1.
ITEM-ITEM_NAME = '2'.
ITEM-CLASS = CL_GUI_LIST_TREE=>ITEM_CLASS_TEXT.
ITEM-LENGTH = 4.
ITEM-USEBGCOLOR = 'X'.
ITEM-TEXT = I_FINAL-MTART.
"ITEM-TEXT = '01'.
APPEND ITEM TO ITEM_TABLE.
CLEAR ITEM.
item-node_key = c_nodekey-new1.
ITEM-ITEM_NAME = '3'.
ITEM-CLASS = CL_GUI_LIST_TREE=>ITEM_CLASS_TEXT.
ITEM-LENGTH = 11.
ITEM-USEBGCOLOR = 'X'.                                    "
"ITEM-TEXT = 'Zert'.
ITEM-TEXT = I_FINAL-IDNRK+9(9).
APPEND ITEM TO ITEM_TABLE.
CLEAR ITEM.
item-node_key = c_nodekey-new1.
ITEM-ITEM_NAME = '4'.
ITEM-CLASS = CL_GUI_LIST_TREE=>ITEM_CLASS_TEXT.
ITEM-ALIGNMENT = CL_GUI_LIST_TREE=>ALIGN_AUTO.
ITEM-FONT = CL_GUI_LIST_TREE=>ITEM_FONT_PROP.
item-text = ''(006).
APPEND ITEM TO ITEM_TABLE.
ENDLOOP.
but dump error is occured when record is greater than one.
with one record report is running successfully.
plz reply as soon as possible
thanx in advance.

Org unit tree

hallow did some have a exemple of report like tree of org unit that when you open u see org unit and under org unit and employee regards

U can have a look at some demo reports by SAP for tree structure development.
SAPSIMPLE_TREE_CONTROL_DEMO
SAPCOLUMN_TREE_CONTROL_DEMO
SAPTLIST_TREE_CONTROL_DEMO
Hope these reports will be helpful for U.

ALV Tree Edit mode

Hi,
I have wrote a program using CL_GUI_ALV_TREE.
I want to make some of the columns editable.
Alternatively, is it possible to include a tree structure in normal CL_GUI_ALV_GRID?
Thanks.
Michael Pang

Hi Leif,
I have not achieved that myself. Maybe you could use a different approach: display the fields into the tree, then use another subscree to show the field contents and allow the user to chage it.
You could find useful these demo programs: SAPSIMPLE_TREE_CONTROL_DEMO, SAPCOLUMN_TREE_CONTROL_DEMO, SAPTLIST_TREE_CONTROL_DEMO, SAPTLIST_TREE_CONTROL_DEMO_HDR, because they show a tree and then, in another subscreen, they show some properties of the selected fields and so.
I hope it helps. Best regards,
Alvaro

Problem with Copied Code finding Public Method

Hi Guys,
I'm an old R/2 programmer trying to get my head around OO coding.
I have copied, in it's entirety, the SAP example program SAPTLIST_TREE_CONTROL_DEMO, as I'm trying to create a Tree based access to reports (don't ask, the user just wants it!).
I've copied and activate all the standard include programs as follows:
*& Modulpool ZMM_COCKPIT_DISPLAY *
INCLUDE ZMMC_COCKPIT_DISPLAY_TOP.
INCLUDE ZMMC_COCKPIT_DISPLAY_CL1.
INCLUDE ZMMC_COCKPIT_DISPLAY_O01.
INCLUDE ZMMC_COCKPIT_DISPLAY_I01.
INCLUDE ZMMC_COCKPIT_DISPLAY_F01.
All the programs syntax check successfully, except ZMMC_COCKPIT_DISPLAY_F01 which displays the error message 'Method "HANDLE_NODE_DOUBLE_CLICK" is unknown or PROTECTED or PRIVATE', yet this does not prevent the include program from activating.
The Section of code that is failing is:
assign event handlers in the application class to each desired event
SET HANDLER G_APPLICATION->HANDLE_NODE_DOUBLE_CLICK FOR G_TREE.
SET HANDLER G_APPLICATION->HANDLE_ITEM_DOUBLE_CLICK FOR G_TREE.
SET HANDLER G_APPLICATION->HANDLE_EXPAND_NO_CHILDREN FOR G_TREE.
SET HANDLER G_APPLICATION->HANDLE_LINK_CLICK FOR G_TREE.
SET HANDLER G_APPLICATION->HANDLE_BUTTON_CLICK FOR G_TREE.
SET HANDLER G_APPLICATION->HANDLE_CHECKBOX_CHANGE FOR G_TREE.,
When double clicking on the HANDLE_NODE_DOUBLE_CLICK, the SAP then goes to the following code in the ZMMC_COCKPIT_DISPLAY_CL1 program:
CLASS LCL_APPLICATION DEFINITION.
PUBLIC SECTION.
 METHODS:
 HANDLE_NODE_DOUBLE_CLICK
 FOR EVENT NODE_DOUBLE_CLICK
 OF CL_GUI_LIST_TREE
 IMPORTING NODE_KEY,
 HANDLE_EXPAND_NO_CHILDREN

 OF CL_GUI_LIST_TREE
 IMPORTING NODE_KEY,
 HANDLE_ITEM_DOUBLE_CLICK
 FOR EVENT ITEM_DOUBLE_CLICK
 OF CL_GUI_LIST_TREE
 IMPORTING NODE_KEY ITEM_NAME,
 HANDLE_BUTTON_CLICK
 FOR EVENT BUTTON_CLICK
 OF CL_GUI_LIST_TREE
 IMPORTING NODE_KEY ITEM_NAME,
 HANDLE_LINK_CLICK
 FOR EVENT LINK_CLICK
 OF CL_GUI_LIST_TREE
 IMPORTING NODE_KEY ITEM_NAME,
 HANDLE_CHECKBOX_CHANGE
 FOR EVENT CHECKBOX_CHANGE
 OF CL_GUI_LIST_TREE
 IMPORTING NODE_KEY ITEM_NAME CHECKED.
ENDCLASS.
CLASS LCL_APPLICATION IMPLEMENTATION.
METHOD HANDLE_NODE_DOUBLE_CLICK.
 " this method handles the node double click event of the tree
 " control instance
 " show the key of the double clicked node in a dynpro field
 G_EVENT = 'NODE_DOUBLE_CLICK'.
 G_NODE_KEY = NODE_KEY.
ENDMETHOD.
Lastly, the class definition, implementation and other required objects are defined in the ZMMC_COCKPIT_DISPLAY_TOP program as:
*& Include ZMMC_COCKPIT_DISPLAY_TOP *
REPORT SAPTLIST_TREE_CONTROL_DEMO MESSAGE-ID TREE_CONTROL_MSG.
Screen Element Components *********************
CLASS LCL_APPLICATION DEFINITION DEFERRED.
CLASS CL_GUI_CFW DEFINITION LOAD.
CAUTION: MTREEITM is the name of the item structure which must
be defined by the programmer. DO NOT USE MTREEITM!
TYPES: ITEM_TABLE_TYPE LIKE STANDARD TABLE OF ZMMC_TREEITM
 WITH DEFAULT KEY.
DATA: G_APPLICATION TYPE REF TO LCL_APPLICATION,
 G_CUSTOM_CONTAINER TYPE REF TO CL_GUI_CUSTOM_CONTAINER,
 G_TREE TYPE REF TO CL_GUI_LIST_TREE,
 G_OK_CODE TYPE SY-UCOMM.
(NB: ZMMC_TREEITM is a copy of the structure MTREEITM).
All the programs are active, and have no syntax errors.
Any ideas on how to make the error message vanish? I don't know, but it must be resolved because it is causing the program to abend at runtime, claiming that the HANDLE_NODE_DOUBLE_CLICK cannot pass value 'NULL' to G_TREE.
Thanks in advance.

I am not sure if I am correct but it appears that class CL_GUI_LIST_TREE does not provide any method to get hold of the node or item details. Thus, I collect them in my global itabs.

Securing action box items with authority-check object

In a 4.6c environment I have setup action box items for various sm and QM notifications.
I would like to secure some of the action box items that their execution is only allowed by authorized personnel using authority-check objects.
Is there a way to secure the action box item by the item number? If not the action box items are using a function module. Maybe I could use the fm name in the authority-check.
Any ideas would be greatly appreciated.

Hi,
just see these examples
SAPTLIST_TREE_CONTROL_DEMO_HDR
SAPTLIST_TREE_CONTROL_DEMO
SAPTLIST_TREE_MODEL_DEMO
and for getting a checkbox we have to repalce the icon what is there in the example program and handle the checked and unchecked event for the checkbox.
this can be achieved by using object oriented methods...
reward if helpful
rgds,
Prajith
