How I can check which event (button) was pressed, when working with floor plan manager. The  standard buttons is defined on the top.I must handle some stuf when the button was pressed. I tried something like this but can't finde the event.

DATA: lo_idr TYPE REF TO if_fpm_idr,

lo_fpm TYPE REF TO if_fpm.

lo_fpm = cl_fpm_factory=>get_instance( ).

lo_idr ?= lo_fpm->get_service(

cl_fpm_service_manager=>gc_key_idr ).

data: lv_1 type string,

      lv_2 type string.

CALL METHOD LO_IDR->GET_APPLICATION_TITLE

  IMPORTING

    EV_TITLE         = lv_1

    EV_TITLE_TOOLTIP = lv_2

    .
