Tree node in open mode when moudle pool executed....

[Former Member]

Hello Gurus,

I have written following code in PBO of a screen which uses custom control for building node table of Tree. Now when the program is executed, the parent node is closed and to see the child of this parent node I have to drill down on parent node.

But my requirement is I want the child node already open under parent node? How Can I do this ?

• Node with key 'Root'

NODE-NODE_KEY = 'PARENT'.

CLEAR NODE-RELATKEY. " Special case: A root node has no parent

CLEAR NODE-RELATSHIP. " node.

NODE-HIDDEN = ' '. " The node is visible,

NODE-DISABLED = ' '. " selectable,

NODE-ISFOLDER = 'X'. " a folder.

CLEAR NODE-N_IMAGE. " Folder-/ Leaf-Symbol in state "closed":

CLEAR NODE-EXP_IMAGE." Folder-/ Leaf-Symbol in state "open"

NODE-EXPANDER = 'X'. " The node is marked with a '+', although

NODE-TEXT = 'Parent'.

APPEND NODE TO NODE_TABLE.

CLEAR NODE.

NODE-NODE_KEY = CHILD.

NODE-RELATKEY = 'PARENT''.

NODE-RELATSHIP = CL_GUI_SIMPLE_TREE=>RELAT_LAST_CHILD.

NODE-ISFOLDER = 'X'.

NODE-TEXT = 'CHILD'.

NODE-N_IMAGE = '@I2@'.

APPEND NODE TO NODE_TABLE.

Jainam.

Use method EXPANDE_NODE for the PARENT node.

Like:

    CALL METHOD W_TREE->EXPAND_NODE
      EXPORTING
        NODE_KEY            = 'PARENT'
      EXCEPTIONS
        FAILED              = 1
        ILLEGAL_LEVEL_COUNT = 2
        CNTL_SYSTEM_ERROR   = 3
        NODE_NOT_FOUND      = 4
        CANNOT_EXPAND_LEAF  = 5.
    IF SY-SUBRC <> 0.
      MESSAGE A000(TREE_CONTROL_MSG).
    ENDIF.
