problem in function module for expand in tree display

[Former Member]

hi all,

i have found a function module which can expand all nodes of the tree.

it is TREEV_EXPAND_ROOT_NODES.

CALL FUNCTION 'TREEV_EXPAND_ROOT_NODES' "Expands all Root Nodes

EXPORTING

handle = " cntl_handle Handle for Tree Control

level_count = " i Number of Levels to be Expanded

expand_all_children = " c

• no_flush = " c

EXCEPTIONS

FAILED = 1 " General Error

ILLEGAL_LEVEL_COUNT = 2 . " LEVEL_COUNT Must Be GE 0

for above function call what value should i give for "handle parameter".

thanks.

Hi,

Please pass the value as below with minor changes as per your requirement.

DATA: tree TYPE cntl_handle,

DATA: TREE_HANDLE TYPE CNTL_HANDLE.

data: local_rep like sy-repid,

local_scr like sy-dynnr.

constants: dynpro_default type i value -1.

data: node_table type node_table_type,

constants : TREEV_NODE_SEL_MODE_SINGLE TYPE I VALUE 0,

call function 'TREEV_CREATE_SIMPLE_TREE'

exporting

owner_repid = local_rep

dynnr = local_scr

left = 0

top = 0

width = 45

height = 22

no_flush = space

shellstyle = style

parentid = dynpro_default

node_selection_mode = treev_node_sel_mode_single

node_table_structure_name = 'MTREESNODE'

tables

node_table = node_table

changing

handle = tree_handle

exceptions

create_error = 1

tree_control_not_existing = 2

cntl_system_error = 3

failed = 4

illegal_node_selection_mode = 5

missing_node_structure_name = 6

error_in_node_table = 7

dp_error = 8

illegal_owner_repid = 9

table_structure_name_not_found = 10

others = 11.

if sy-subrc <> 0.

message e645 with text-745 sy-subrc.

endif.

call function 'TREEV_EXPAND_ROOT_NODES'

exporting

handle = tree_handle

level_count = 2

expand_all_children = 'X'

no_flush = ' '

exceptions

failed = 1

illegal_level_count = 2

cntl_system_error = 3

others = 4.

if sy-subrc <> 0.

message e645 with text-743 sy-subrc.

endif.

If it is helpfull means reward me with some points.

hi chitra,

actually i have created tree display using class cl_gui_simple_tree.

i have used program sapsimple_tree_control_demo.

hence need to expand all nodes of tree.

how should i do this.
