Zitat:
TksTimer is a high resolution replacement for the standard
VCL TTimer component.
TksTimer is a wrapper for the
Win32 API functions CreateTimerQueueTimer and DeleteTimerQueueTimer.
When the Enabled property of TksTimer instance is assigned True, an underlying queue timer is created. If DueTime is nonzero and Period is zero, the timer is signaled only once after due time. If the DueTime and Period properties are both nonzero, the timer will be signaled first at the due time, then periodically. A periodic timer automatically reactivates each time the period elapses, until an underlying queue timer is canceled by setting the Enabled property to False. When the timer is signalled, the OnTimer event is triggered. The timer events are subject to scheduling delays, so the timing can vary depending on what else is happening in the application or the system.
