Fire Plugs Between Windows

[Former Member]

We have a list in a view in a WDA window (A) which is bound to an internal table. When the user clicks a button, a popup WDA window is opened (B) which allows them to add something to the list. When window B is closed, how can we inform the view in window A to refresh? Refreshing on every WDOMODIFYVIEW seems a waste. Is there any way for windows to communicate an event perhaps with inter-window plugs?

Hi,

if_wd_window provides SUBSCRIBE_TO_BUTTON_EVENT.

You can use this method to subscribe to the event of the popup window.

I don't understand how the f_wd_window=>co_button_yes can work -> my popup has no "YES" button.

Could you provide a code example which shows a) the window B being opened and b) the code in the window B which fires the event?

Hi,

How do you generate popup window ? What buttons does it have ?

If it is your custom view then you have to define a event in component controller. Fire this event from popup view and Subscribe this event in your main view.

lo_window         = lo_window_manager->create_window(
                  window_name            = 'W_ADDSUB'
                  title                  = lv_text
                  close_in_any_case      = abap_true
                  message_display_mode   = if_wd_window=>co_msg_display_mode_selected
                  close_button           = abap_true
                  message_type           = if_wd_window=>co_msg_type_none
                  ).

Ok,

as i already said, you can create a event in component controller.

Fire this event from popup view.

Subscribe this event in view

That sounds like a workaround which is not much better than what I currently do: firing an outbound plug on Window A from the view in Window B.

DATA lo_window       TYPE REF TO ig_w_main.
o_window = wd_this->get_w_main_ctr( ).
lo_window->fire_subscription_added_plg( ).

Hi Marc,

Can you please explain me how do you get it worked navigating from popup window to a parent window via outbound plug ?

Probably you already have better solution.

I have posted what i would do and recommend.

First, add the window A (e.g. W_MAIN) as a usage to your view B (under properties).

When the user clicks "Add" in your popup window B you fire the outbound plug of your window A:

DATA: lo_window TYPE REF TO ig_w_main.
lo_window = wd_this->get_w_main_ctr( ).
lo_window->fire_yourplug_plg( ).

Now all you do is wire your outbound window A plug to the view you want to refresh. In that view the HANDLEIN does all the refreshing from any plug input so the refresh code is in one place.
