ALV Treee (CL_GUI_ALV_TREE) hot spot functionality

[Former Member]

Hi,

I am displaying the data using CL_GUI_ALV_TREE at 3 node levels. When I click on one of the column(hotspot column) it should navi gate to some other scrreen to display some log information.

How could we transport the data from this ALV tree screen to second screen.

Already mention the hotspot = x in filed catalogue

and item_selection = 'X' when creating the tree control..

Also when I have clicked on the hotspot its not triggring , I have used the event METHODS handle_item_double_click

FOR EVENT item_double_click OF cl_gui_alv_tree

IMPORTING node_key fieldname.

Do we need to assign the function code for this hotspot?

Can you please suggest how can we trigger the hotspot and need to navi gate to seond screen.

Thanks in advance.

Best Regards,

hotspot is 1 click and u have used double click event. So are clicking the item once or twice??

you need to set the handler too before displaying your tree.

use keyword Set handller

Hope this will help!!!

Please refer standard program BCALV_TREE_02 . You will see how to register and handle the events for tree correctly.

As Marcin mentioned, you need to register the TREE events properly.

Something like:

    DATA: lt_events TYPE cntl_simple_events,
          l_event TYPE cntl_simple_event.

    CALL METHOD g_alv_tree->get_registered_events
      IMPORTING
        events = lt_events.

    l_event-eventid = cl_gui_column_tree=>EVENTID_ITEM_DOUBLE_CLICK.
    APPEND l_event TO lt_events.

    CALL METHOD g_alv_tree->set_registered_events
      EXPORTING
        events                    = lt_events
      EXCEPTIONS
        cntl_error                = 1
        cntl_system_error         = 2
        illegal_event_combination = 3.
