Capture user action from method cl_wd_popup_factory=>popup

Hi There,

Just wondering if anyone can explain to me how i capture what button a user pressed when using the method 'cl_wd_popup_factory=>popup' and how I perfor different methods/ functionality depending on what they pressed.

At the moment i can create the popup using the code below but it is not displayed untill the current method has been completed, at this point it seems too late to allow me to control of the code.

call method cl_wd_popup_factory=>popup

EXPORTING

component = lr_component_api

view_name = 'VIEW2'

button_kind = if_wd_window=>CO_BUTTONS_YESNO

message_type = if_wd_window=>CO_MSG_TYPE_QUESTION

IMPORTING

POPUP_WINDOW = window

COMPONENT_USAGE = comp_usage.

Any ideas would be much appreciated

Regards

Martin
