Right click tree node

Question

Hello all,
I need to process right click on the tree node. I can get the node and process the action well. But the problem is that the selected node doesn't have a gray box (selection indicator) like when I left click it.
Please help me with this,
Thanks,
Fantabk

Dear Siva,
You can follow the following steps:-
- Create local class (eg:- lcl_screen_handler) as handler class.
- Define and implement methods handle_node_context_menu_req and handle_node_context_menu_sel for handling right click.
- In Method handle_node_context_menu_req use CALL METHOD menu->add_function for adding entries to context menu.
- In Method handle_node_context_menu_sel based on node_key and fcode handle logic for right click.
- Define event handler (eg:- grc_event_handler     TYPE REF TO lcl_screen_handler) to handle events for right click on tree.
- After creating Tree, specify events that are to be handled and assign them to tree instance
eg:- lwa_event-eventid = cl_simple_tree_model=>eventid_node_double_click.
      lwa_event-appl_event = ' '.   "system event, does not trigger PAI
      APPEND lwa_event TO lit_event. (where, lit_event TYPE cntl_simple_events)
- Also, register PAI for context menu as follows:-
Process PAI if context menu select event occurs
  CALL METHOD grc_tree->set_ctx_menu_select_event_appl (where grc_tree is Tree instance)
    EXPORTING
      appl_event = 'X'.
- Register Tree events as follows:-
CALL METHOD grc_tree->set_registered_events
    EXPORTING
      events                    = lit_event ....
- Create event handler instance for tree
  CREATE OBJECT grc_event_handler. (where, grc_event_handler is already declared on top)
- Set event handler method to handle various events on tree node
eg:-  SET HANDLER grc_event_handler->handle_node_double_click FOR grc_tree.
        SET HANDLER grc_event_handler->handle_node_context_menu_req FOR grc_tree.
        SET HANDLER grc_event_handler->handle_node_context_menu_sel FOR grc_tree.
The events should be handled now. I have followed this approach and it worked for me.
