Tick - TPdfReadingSession - PDFium Delphi Component

根据宿主语音引擎状态推进或估算朗读进度

Syntax

procedure Tick(SpeechStillBusy: Boolean; ElapsedMs: Cardinal = 0);

SpeechStillBusy	`Boolean` - 当前分块仍在朗读时为 True
ElapsedMs	`Cardinal` - 当前分块的经过时间，仅在启用 EstimatePacing 时使用

如果引擎仍在忙且启用了 EstimatePacing，该方法从 ElapsedMs 估算当前单词

如果引擎不再忙，会话前进到下一个分块或完成并触发 OnFinished

API names, type names, file names, and PDF terms keep their original spelling so code search remains reliable

ReadingSession1.Tick(SpeechEngineBusy, ElapsedMs);
