Get the TActionType of the ActIndex-th action attached to

Category	Actions
Availability	Partial — same GoToE/SetOCGState/Movie gap as `pdfGetActionType`

Purpose — Get the TActionType of the ActIndex-th action attached to (ObjType, ObjHandle).

Description — Unlike pdfGetActionHandle, this getter walks the general per-object attachment table (populated by the V12 pdfAddActionToObj family) — ObjType/ObjHandle here are consulted for real, not limited to one hardcoded combination.

Declarations

int32_t __stdcall pdfGetActionTypeEx(PPDF IPDF, TObjType ObjType, uint32_t ObjHandle, uint32_t ActIndex);

Delphi

function pdfGetActionTypeEx(const IPDF: PPDF; ObjType: TObjType; ObjHandle, ActIndex: Cardinal): Integer; stdcall; external 'LumasPdf.dll';

Parameters

Parameter	Type	Description
`IPDF`	`PPDF`	Instance handle.
`ObjType`	`TObjType`	Owning object's type.
`ObjHandle`	`Cardinal`	Owning object's handle.
`ActIndex`	`Cardinal`	Zero-based index into that object's attached-action list.

Return value — Ord(TActionType) on success; -1 if no such attachment exists at that index, or if the attached action is GoToE/SetOCGState/Movie (see the chapter-level gap note).
