In my webdynpro abap app, I have a modal popup window generated by code like this:
lo_window = lo_window_manager->create_and_open_popup( window_name = 'W001' title = 'My title' 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 ).
The popup window will have a 'X' on the top-right corner, I want to bind an Action to it, so I can do something when user close the window by clicking 'X'.
My question is, how to bind? Thanks.
