Tree Problem

[former_member216100]

Dear all,

I use CL_GUI_SIMPLE_TREE and it works OK but

I need to add a node, I insert it into the internal table

node_tables but how I can refresh the screen that I

can see the new node ?

Please help.

Thanks.

Did you set the UPDATE flag on so that changes to the tree control should be visible immediately.

CALL METHOD tree->set_screen_update
  EXPORTING
    UPDATE = UPDATE
  EXCEPTIONS
    failed = 1
    cntl_system_error = 2.

I tried but dont work

I can see that the new node is in the internal table

but I can not see it on the screen.

[RaymondGiuseppi]

How did you add the nodes, did you use

CALL METHOD simple_tree->add_nodes
  EXPORTING 
    table_structure_name = table_structure_name
    node_table = node_table
  EXCEPTIONS
    error_in_node_table = 1
    failed = 2
    dp_error = 3
    table_structure_name_not_found = 4.

[former_member216100]

No because I tried and I got a dump.

MESSAGE_TYPE_X

METHOD FLUSH .

do I need to call a flush first before I call add_nodes ?

I just filled the internal table with the new node.

if you can provide me a sample abap with adding

a new node would be great !!!

Thanks

Look at this program :[RSDEMO_DRAG_DROP_EDIT_TREE|http://help.sap.com/saphelp_erp2004/helpdata/en/c0/64b4c7c74411d2bd93080009b4534c/frameset.htm]

Also don't hesitate to use the SAP demo transactions

- SE83

- DEMO_TRANSACTION

- DEMO_SCREEN_FLOW

- DWDM, etc.
