Id like to manage the buttonpress or release event on an object ie. an image using ST and not the visualization. I found that there is a library for this, cmp3clutter, but i couldnt find out how to use it properly and there is no example of usage anywhere.
If somebody could help me it would be much appreciated.

I was able to do it and i leave the code for someone who might need it.
//Declare global variables to associate with the actions you want the objects to do
buttonenter1 : UDINT;
buttonleave1 : UDINT;

//in the LoopCode you have to associate each variable to the event you want to register
IF pagina<>paginaanterior THEN
buttonenter1:= PantallaPrincipal.PowerButton.RegisterEvent(ADR(Events.EVENT_ENTER));
buttonleave1:= PantallaPrincipal.PowerButton.RegisterEvent(ADR(Events.EVENT_LEAVE));
paginaanterior:=pagina;
END_IF

//In MyEvents(FUN) you can say to the program what to do each time an event is triggered.

CASE pagina OF

1:
    IF event.ID= buttonenter1 THEN
        plc_prg.power:=TRUE;    
    ELSIF event.ID=buttonleave1 THEN
        plc_prg.power:=FALSE;   
    END_IF

end_case

Hey,
I am unsure what you are trying to do?

Why is "Execute ST Code" not usable for you?

Best regards,
Marcel

Is not very clear what do you want?
But a simple event press and release with debounce could be as follow:

VAR
  tmDebounce : TON;
  oldState : BOOL;
END_VAR

....

tmDebounce(IN := buttonState <> oldState, PT := T#50ms);
IF tmDebounce.Q THEN
  oldState := buttonState;
  IF buttonState THEN
    eventPressFunction();
  ELSE
    eventReleaseFunction();
  END_IF
END_IF

Functions, or if you prefer methods or actions are called only once after debounce time on falling or rising edges.
