ABAP: extract messages from message class

Question

Hello all,
I have a message class and now I need to extract some messgae from it and pass them to some methods. For instance, to a pop up window.
How do I extract messages from that class?
Thank you.

Hi Georgy,
  Are you trying to use a confirmation window with a standard "Ok" and "Cancel" button. Then you can do something like this:
method onactionpopup4_1 .
  data: l_cmp_api          type ref to if_wd_component,
        l_window_manager   type ref to if_wd_window_manager,
        l_popup            type ref to if_wd_window,
        l_text             type string_table,
        l_api              type ref to if_wd_view_controller.
  l_cmp_api        = wd_comp_controller->wd_get_api( ).
  l_window_manager = l_cmp_api->get_window_manager( ).
  insert `Data where changed` into table l_text.    "#EC *
  insert `Do you want to save?`        into table l_text.    "#EC *
  l_popup = l_window_manager->create_popup_to_confirm(
                text            = l_text
                button_kind     = if_wd_window=>co_buttons_yesnocancel
                message_type    = if_wd_window=>co_msg_type_question
                window_title    = 'Test: Popup to confirm'
                window_position = if_wd_window=>co_center )."#EC *
  l_api = wd_this->wd_get_api( ).
  l_popup->subscribe_to_button_event(
               button            = if_wd_window=>co_button_yes
               action_name       = 'YES'
               action_view       = l_api
               is_default_button = abap_true ).
  l_popup->subscribe_to_button_event(
               button            = if_wd_window=>co_button_no
               action_name       = 'NO'
               action_view       = l_api
               is_default_button = abap_false ).
  l_popup->subscribe_to_button_event(
               button            = if_wd_window=>co_button_cancel
               action_name       = 'CANCEL'
               action_view       = l_api
               is_default_button = abap_false ).
  l_popup->open( ).
endmethod.
Or else if you have your own pop-up window, then you can just declare a message area and report a message there using the code that I had written in my last post.
