Last menu tree node

[giancarla_aguilar]

The nodes of the menu tree in my program are all folders. The folder should be open upon double click of that node. The last node is a folder and does not have any children. But upon double click of that last folder node, it does not open and the folder preceeding it remains open. How do I solve this?

I put a expand_no_children event but it seems it does not pass thru its method.

I have this in the PBO area of my screen:

" node double click

lw_event-eventid = cl_gui_simple_tree=>eventid_node_double_click.

lw_event-appl_event = 'X'.

APPEND lw_event TO lt_events.

" expand no child

lw_event-eventid = cl_gui_simple_tree=>eventid_expand_no_children.

lw_event-appl_event = 'X'.

APPEND lw_event TO lt_events.

CALL METHOD g_tree->set_registered_events

EXPORTING

events = lt_events

EXCEPTIONS

cntl_error = 1

cntl_system_error = 2

illegal_event_combination = 3.

IF sy-subrc <> 0.

MESSAGE a000(tree_control_msg).

ENDIF.

• 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_expand_no_children FOR g_tree.

Is there another event I should use? Or is there a setting I should tick in the definition of the nodes:

lw_node-node_key = 'ROOT'. " Root/Key of the node

lw_node-text = text-t01.

CLEAR lw_node-relatkey. " Special case: A root node has no parent

CLEAR lw_node-relatship. " node.

lw_node-hidden = ' '. " The node is visible,

lw_node-disabled = ' '. " Selectable

lw_node-isfolder = 'X'. " Folder

CLEAR lw_node-n_image. " Folder-/ Leaf-Symbol in state "closed":

lw_node-exp_image = 'X'. " Folder-/ Leaf-Symbol in state "open":

CLEAR lw_node-expander. " the width of the item is adjusted to its content (text)

APPEND lw_node TO gt_nodetab.

• Node with key 'Child1'

CLEAR lw_node.

lw_node-node_key = 'CHILD1'. " Key of the node

lw_node-text = text-t02.

lw_node-relatkey = 'ROOT'.

lw_node-relatship = cl_gui_list_tree=>relat_last_child.

lw_node-isfolder = 'X'.

APPEND lw_node TO gt_nodetab.

Thanks in advance!
