Бележки за употреба
- The method removes only the selected trigger entry and keeps other annotation actions unchanged
- If the annotation /AA dictionary becomes empty, the dictionary entry is removed from the annotation
- Use SetAnnotationAdditionalAction to install a replacement THPDFActionBuilder chain for the same trigger
- Use THotPDF form-field action convenience helpers when the target annotation is an AcroForm widget selected by field name
