[Former Member]

Hi Gurus,

      We have two windows(each window have separate view),Now iam calling one window(view1) to

another window(view2) by using CREATE_AND_OPEN_POPUP,whenever the 2nd window(along with 2nd viw\ew) opens

one OK button is coming on that popup,Now how to handle this popup .Any one could u please suggest me the solution

below is the code am using....

DATA LO_WINDOW_MANAGER TYPE REF TO IF_WD_WINDOW_MANAGER.

DATA LO_API_COMPONENT  TYPE REF TO IF_WD_COMPONENT.

DATA LO_WINDOW         TYPE REF TO IF_WD_WINDOW.

DATA LT_BUTTONS        TYPE WDR_POPUP_BUTTON_LIST.

DATA LS_CANC_ACTION    TYPE WDR_POPUP_BUTTON_ACTION.

Data ls_buttons like LINE OF LT_BUTTONS.

Data ls_CANCEL_ACTION type WDR_POPUP_BUTTON_ACTION.

     ls_buttons-BUTTON = '7'.

     ls_buttons-BUTTON = '8'.

append ls_buttons to lt_buttons.

ls_CANCEL_ACTION-ACTION_NAME = 'OK'.

LO_API_COMPONENT           = WD_THIS->WD_GET_API( ).

LO_WINDOW_MANAGER          = LO_API_COMPONENT->GET_WINDOW_MANAGER( ).

* create the cancel icon, but without any action handler

LS_CANC_ACTION-ACTION_NAME = 'OK'.

* Simple example, see docu of method create_and_open_popup for details

LT_BUTTONS                 = LO_WINDOW_MANAGER->GET_BUTTONS_OK(

    default_button       = if_wd_window=>co_button_ok

).

LO_WINDOW                  = LO_WINDOW_MANAGER->CREATE_AND_OPEN_POPUP(

    WINDOW_NAME          = 'INVOICES_WIN'

    title                = 'Bill Initiation Process'

    MESSAGE_TYPE         = IF_WD_WINDOW=>CO_MSG_TYPE_NONE

    MESSAGE_DISPLAY_MODE = IF_WD_WINDOW=>CO_MSG_DISPLAY_MODE_SELECTED

*    is_resizable         = ABAP_TRUE

    BUTTONS              = LT_BUTTONS

    CANCEL_ACTION        = LS_CANC_ACTION

).

Hi Kranthi,

Use the method: SUBSCRIBE_TO_BUTTON_EVENT( ).

Logic to be implemented below your code:

     Data: lr_view_controller TYPE REF TO if_wd_view_controller.

   lr_view_controller = wd_this->wd_get_api( ).

  CALL METHOD lo_window->subscribe_to_button_event   " register event before opening window

    EXPORTING

      button                 = if_wd_window=>co_button_ok

      action_name       = 'OK'   " You have to create action OK in Actions tab & write req handling

      action_view         = lr_view_controller.

Thanks & Regards,

thank you  kirankumar,ramakrishnappa,sankar ....

                Iam writing the above code in compoent level.So it is throwing syntax error for the below statement.

                          lr_view_controller = wd_this->wd_get_api( ).

                     It might be throwing becoz we are not maintaing view controller reference.So how we can maintain view conctroller reference in component controller...

                                      Thanks in advance....

Hi,

Go to attributes tab of Component controller and create an attribute, say, gv_view_controller of type ref to if_wd_view_controller.

Then in WDDOINIT method of your view, set the reference, using

wd_comp_controller->gv_view_controller = wd_this->wd_get_api( ).

Then pass wd_this->gv_comp_controller to the subscribe to button event method in Component controller,

Or, If you are calling the component controller method from View, create an importing parameter in the component controller method and pass the view controller reference.

Hi Kranthi,

You can set the button text as below

  CALL METHOD lo_window->subscribe_to_button_event 

    EXPORTING

      button                 = if_wd_window=>co_button_ok

      button_text   = 'Submit'

      action_name       = 'OK' 

      action_view         = lr_view_controller.

Hope this helps you.

Hi Syed,

Please elaborate your requirement little more.

Do you want to read button and then get action name associated with that button?

Are you creating post_exit for WDDOMODIFYVIEW( )?

Hi Syed,

The method BUTTON_PRESSED( ) is called from on action BUTTON_PRESSED and event reference is passed to parameter io_event

Now, you can get the event id as below

data           lv_action_id type string.

  lv_action_id = io_event->get_string( 'ACTION_ID' ).

Hope this helps you.

If you still need further assistance on the same please create a new question, as this discussion is of different topic.

Regards,

Rama

HI Ram,

              I already used this code

data           lv_action_id type string.

  lv_action_id = io_event->get_string( 'ACTION_ID' ).

but am getting error that io_event is unknown and i have to pass ACTION_ID is my button id name or button name.

I don't want to pass event id directly ...i have to read when user perform some action on particular button then only i have to trigger my logic.

Hi,

Use SUBSCRIBE_TO_BUTTON_EVENT method of window before opening window.

Use Create_window method.

Code Snippet:

DATA lr_window_manager TYPE REF TO if_wd_window_manager.
  DATA lr_api_component  TYPE REF TO if_wd_component.
  DATA lr_window         TYPE REF TO if_wd_window.
  data lr_view_controller TYPE REF TO if_wd_view_controller.


  lr_api_component  = wd_comp_controller->wd_get_api( ).
  lr_window_manager = lr_api_component->get_window_manager( ).
  lr_window         = lr_window_manager->create_window(
                     window_name            = 'INVOICES_WIN'
                     message_display_mode   = if_wd_window=>co_msg_display_mode_selected
                     button_kind            = if_wd_window=>co_buttons_ok
                     message_type           = if_wd_window=>co_msg_type_none
                     default_button         = if_wd_window=>co_button_ok
                     ).


   lr_view_controller = wd_this->wd_get_api( ).


  CALL METHOD lo_window->subscribe_to_button_event   " register event before opening window
    EXPORTING
      button            = if_wd_window=>co_button_ok
      action_name       = 'OK'   " You have to create action OK in Actions tab & write req handling
      action_view       = lr_view_controller.




  lo_window->open( ).

Hope this helps u,
