Popover

To show a popover, call client->popover_display and pass the ID of the control the popover should attach to:

CLASS z2ui5_cl_sample_popover DEFINITION PUBLIC.

  PUBLIC SECTION.
    INTERFACES z2ui5_if_app.

  PROTECTED SECTION.

Like popups, a popover picks up changed ABAP values on its own: the framework compares the model before and after main( ) and pushes the difference into the open popover, without re-rendering its XML. A handler that only changes data has nothing else to call.
