Closing external window.

[Former Member]

Hi,

I have to close the external window which is called as a pop-up window.

code for it is

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.

lo_api_component = wd_comp_controller->wd_get_api( ).

lo_window_manager = lo_api_component->get_window_manager( ).

lo_window = lo_window_manager->create_window(

window_name = 'SECOND'

title = 'SECOND'

close_in_any_case = abap_false

message_display_mode = if_wd_window=>co_msg_display_mode_selected

close_button = abap_true

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

).

lo_window->open( ).

Now through enhancement I have to close it

Kindly provide me solution for the same

For closing I was using the code

Closing a pop up window

data:

l_api type ref to if_wd_view_controller,

l_window_ctlr type ref to if_wd_window_controller,

l_popup type ref to if_wd_window.

l_api = wd_this->wd_get_api( ).

l_window_ctlr = l_api->get_embedding_window_ctlr( ).

if l_window_ctlr is bound.

l_popup = l_window_ctlr->get_window( ).

l_popup->close( 'l_popup' ).

endif.

But its giving me null pointer exception

Can anyone help me???????

hi，

have you tried save the lo_window to your component controller's one attribute? when you need to close the window, just call wd_comp_controller->second_window->close( )?

Hi Reeha,

Go through this [excellent blog by Anzy|https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/6707] [original link is broken] [original link is broken] [original link is broken]; where he explains how you can close popup windows. (The blog is titled as external windows but it does actually refer to popup windows.)

Below is another workaround for the same. You must be callinng a popup by using the code wizard. Within this code at 1 place you would have something like lo_window_manager->create_window( ) which would be returning the reference to this popup window. You can create an attribute of type ref to IF_WD_WINDOW & ave this reference into it. So map this context node even to your popups view. When you want to close this popup just read the context attribute value in your view and call the close( ) method on this reference variable.

Just go through the code snippets below:

To call the popup and save the window reference into a component controller level attribute:

METHOD onactiondisplay_popup .
  DATA: lv_node  TYPE REF TO if_wd_context_node,
        lv_kunnr TYPE ig_componentcontroller=>element_kna1-kunnr,
        lt_vbak  TYPE ig_componentcontroller=>elements_vbak.


*   get message manager
  DATA lo_api_controller     TYPE REF TO if_wd_controller.
  DATA lo_message_manager    TYPE REF TO if_wd_message_manager.

  lo_api_controller ?= wd_this->wd_get_api( ).

  CALL METHOD lo_api_controller->get_message_manager
    RECEIVING
      message_manager = lo_message_manager.


  lv_node = wd_context->get_child_node( name = 'KNA1' ).

  CALL METHOD lv_node->get_attribute
    EXPORTING
      name  = 'KUNNR'
    IMPORTING
      value = lv_kunnr.

  SELECT * FROM vbak INTO TABLE lt_vbak WHERE kunnr = lv_kunnr.

" If no sales orders exist for the customer then display an error message quoting the same
  IF sy-subrc NE 0.

*   report message
    CALL METHOD lo_message_manager->report_error_message
      EXPORTING
        message_text = 'No sales orders exist for this customer!'.
" If sales orders exist for the customer then display the orders within a popup
  ELSE.
    lv_node = wd_context->get_child_node( name = 'VBAK' ).
    lv_node->bind_table( new_items = lt_vbak ).

    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.

    lo_api_component  = wd_comp_controller->wd_get_api( ).
    lo_window_manager = lo_api_component->get_window_manager( ).
    lo_window         = lo_window_manager->create_window(
                        window_name            = 'POPUP_WINDOW'
                        title                  = 'Working with modal windows in webdynpro!'
                        CLOSE_IN_ANY_CASE      = ABAP_TRUE ).

    lv_node = wd_context->get_child_node( name = 'WINDOW_REFERENCE' ).

    CALL METHOD lv_node->set_attribute
      EXPORTING
        value  = lo_window
        name   = 'REFERENCE'.

    lo_window->open( ).
  ENDIF.
ENDMETHOD.                    "onactiondisplay_popup

To close the popup window:

lv_node = wd_context->get_child_node( name = 'WINDOW_REFERENCE' ).
  CALL METHOD lv_node->get_attribute
    EXPORTING
      name   = 'REFERENCE'
    IMPORTING
      value  = lv_pop_window_ref.
  lv_pop_window_ref->close( ).

HI,

Have you tried using the hook method WDDOEXIT where the window can be closed.

DATA:
    l_api TYPE REF TO if_wd_view_controller,
    l_window_ctlr TYPE REF TO if_wd_window_controller,
    l_popup TYPE REF TO if_wd_window.

  l_api = wd_this->wd_get_api( ).
  l_window_ctlr = l_api->get_embedding_window_ctlr( ).
  IF l_window_ctlr IS BOUND.
    l_popup = l_window_ctlr->get_window( ).
    IF l_popup IS BOUND.
** CLOSE POPUP
      wd_comp_controller->gref_msg_manager->clear_messages( including_permanent_msg = abap_true ).
      l_popup->close( 'DELETE' ).
    ENDIF.                             " IF l_popup IS BOUND
  ENDIF.                               " IF l_window_ctlr IS BOUND
