Hi,

There is a demo program which can give you a good example as to how to implement the context menu. Have a look at it.

SAPSIMPLE_TREE_CONTEXT_MEN_DEM package - SEU_TREE_CONTROL.

Hope this will help.

Thanks,

Samantak.

hi,

Use CL_CTMENU for context menu.

Use can also try CL_COLUMN_TREE_MODEL for creating tree structure.

CL_SALV_TREE creates a Tree type reference to the class CL_SALV_GUI_TREE which is inherited from the class CL_GUI_ALV_TREE. So, to get the Context Menu on the tree created by the CL_SALV_TREE, you need to :

Define Event Receiver class:


class lcl_handle_events definition.
  public section.
      on_header_context_menu_req for EVENT header_context_menu_request of cl_gui_alv_tree  " <<
        IMPORTING FIELDNAME
                  menu.
endclass.                    "lcl_handle_events DEFINITION

Implement the class:


class lcl_handle_events implementation.
  method on_header_context_menu_req.
*  Access the MENU object
  ENDMETHOD.
endclass.                    "lcl_handle_events IMPLEMENTATION

Now, here is the trick. Set the Event Handler for ALL INSTANCE rather than setting it for the specific instance before calling the DISPLAY method.


    data: gr_events type ref to lcl_handle_events.

    SET HANDLER gr_events->on_header_context_menu_req  FOR ALL INSTANCES . "mr_column_tree.

*... §5 display the table
    gr_tree->display( ).

Same way, you can try to trap the other Context Menu events like ITEM_CONTEXT_MENU_REQUEST, ITEM_CONTEXT_MENU_SELECTED.
