The usage class must implement interface IF_CHIP_WD_EVENT_HANDLER and its method HANDLE_EVENT. To register the class instance as an event handler, proceed as described in the following example:

DATA WD_BUTTON TYPE REF TO CL_WD_BUTTON.

WD_BUTTON->SET_ON_ACTION( IF_CHIP_WD_EVENT_HANDLER=>CO_CHIP_ACTION ).
WD_BUTTON->MAP_ON_ACTION(
  CL_CHIP_UI_EVENT_HELPER=>CREATE_EVENT_MAPPING(
    EVENT_HANDLER = ME  EVENT_NAME = 'BUTTON_PRESSED' ) ).
