THPDFPage.AddPopupAnnotationFor

THPDFPage

Creates a Popup annotation linked to a specific parent markup annotation.

Delphi 语法:

function AddPopupAnnotationFor(ParentAnnot: THPDFDictionaryObject; Rectangle: TRect; Open: Boolean = false): THPDFDictionaryObject;

C++ 语法:

THPDFDictionaryObject* __fastcall AddPopupAnnotationFor(THPDFDictionaryObject *ParentAnnot, const System::Types::TRect &Rectangle, bool Open);

说明

AddPopupAnnotationFor writes a /Popup annotation and links it in both directions: the popup receives /Parent and the parent annotation receives /Popup. Use LastAnnotation after an Add*Annotation call when the parent annotation procedure does not directly return its widget dictionary.

为 ParentAnnot 传入 nil 会保留旧的 standalone popup 行为。高级调用方可在文档保存前自定义返回的 dictionary
