FormFieldTabOrder-metodi

Component: TPdfView  ·  Unit: PDFium
Toimii nykyisen sivun AcroFormin loogisen fokusosoittimen kanssa näppäimistö-, puhe- ja saavutettavuustyönkuluissa

Syntax

function FormFieldTabOrder: TPdfIntegerArray;

Return Value

TPdfIntegerArray. Current-viewer-page widget indices in PDFium tab order

Description

The form-focus members maintain a logical cursor over AcroForm widget annotations on the current page. The cursor follows FormFieldTabOrder and returns -1 when no current-page field is focused

Use these members when an application needs to walk fields from code, drive voice-assisted form filling, or expose the active field to an accessibility layer without relying on mouse hit testing

Remarks

Example

if Pdf1.FormFieldCount > 0 then
  Pdf1.FocusFormField(0);
ShowMessage(Pdf1.FocusedFormFieldText);
