function pdfGetTabOrderModeA(const IPDF: PPDF): PAnsiChar; stdcall;
function pdfGetTabOrderModeW(const IPDF: PPDF): PWideChar; stdcall;
function pdfSetTabOrderModeA(const IPDF: PPDF; Mode: PAnsiChar): Integer; stdcall;
function pdfSetTabOrderModeW(const IPDF: PPDF; Mode: PWideChar): Integer; stdcall;

Purpose. Set/get the document's /Tabs page-attribute default (form field keyboard tab order — Row/Column/Structure order), stored as a string rather than an enum in this ABI.

Description. Unlike pdfGetTabLen/pdfSetSpaceWidthFactor above, this pair is real — SetTabsMode genuinely stores the requested tab order mode for use in the /Tabs page attribute at serialization.

Parameters.

Return value. Getter: the current mode string, or nil if unset / IPDF invalid. Setter: 1 on success; 0 if IPDF invalid.
