OnTimer picture event

Declaration

ENTRY OnTimer
 ; script actions
 END OnTimer


Parameters
No parameters.
Description
The picture event is being generated by the picture every 125 [ms] if so-called timer is enabled. After opening the picture, the generation of the event (the function timer) is disabled.

Generation of the picture event OnTimer can be enabled/disabled by calling the function %HI_TimerEnable.


 
; picture event handler: OnTimer
ENTRY  OnTimer
  ; script actions
 END  OnTimer

 

To ensure the picture event generation, it is required to call the function %HI_TimerEnable. The function can be also called within the handler of other picture event (e.g. pressing the mouse button), or within the initialisation part of the script:


Example
BEGIN
   %HI_TimerEnable(@TRUE)
 END

Note
The picture event OnTimer is generated every 125 [ms]. Therefore it is required that the duration of the picture event handler would be as short as possible, absolutely not longer than 250 [ms]. Otherwise, the system could be overloaded and then the process D2000 HI will be non-functional.
