Dynpro event driven and self-refresh

Former Member — Tue, 13 Sep 2005 14:10:57 GMT

Hi ABAP-ers,

how can I enable some dynpro to be event driven and that is refreshing it self after some time. For exmple, I have transaction that monitors some Jobs in system and if I need to see what happens right now, I need to press F5. So question is, can system in this case refresh it self after every 5 secs?

Thx

Mario

THere are some solutions in the net suggesting to use a call to a FM in new task in combination with a wait command - but this means that all the time a process is blocked (although it does nothing but wait or sleep)

I prefer the solution with CL_GUI_TIMER (I think there is a weblog from Thomas Jung)

If this is your own transaction, then introduce a loop at the refresh process. Just before the endloop, introduce a 'wait up to n seconds'. To avoid an infinite loop, introduce some kind of exit, may be a key when pressed you come out of the loop. You may need SAPGUI_PROGRESS_INDICATOR call inside to avoid timeout.

Thanks all,

this sample of code work just fine for me:

****TOP

data: lcl_max_time type SY-INDEX value '5',

lcl_timer type ref to CL_GUI_TIMER,

lcl_container TYPE REF TO cl_gui_custom_container.

CLASS lcl_event_handler DEFINITION.

PUBLIC SECTION.

CLASS-METHODS: on_finished FOR EVENT finished OF cl_gui_timer.

ENDCLASS. "lcl_event_handler DEFINITION

CLASS lcl_event_handler IMPLEMENTATION.

METHOD on_finished.

Start Timer again

lcl_timer->interval = lcl_max_time .

CALL METHOD lcl_timer->run.

cause PAI

CALL METHOD cl_gui_cfw=>set_new_ok_code

EXPORTING

new_code = 'REFR'.

ENDMETHOD. "on_finished

ENDCLASS. "lcl_event_handler IMPLEMENTATION

DATA event_handler TYPE REF TO lcl_event_handler.

create the thinies container just because of timer
kreirati mali container samo radi timer-a

if lcl_timer is initial.

CREATE OBJECT lcl_container

EXPORTING container_name = 'LCL_CONTAINER'.

CREATE OBJECT lcl_timer EXPORTING parent = lcl_container.

create object event_handler.

SET HANDLER event_handler->on_finished FOR lcl_timer.

lcl_timer->interval = lcl_max_time.

CALL METHOD lcl_timer->run.

ENDIF.

What do you think about this sample of code?

Thx for help
