FocusedFormFieldText - TPdfView

Komponentas: TPdfView · Modulis: PDFium

Veikia su dabartinio puslapio AcroForm loginio židinio žymekliu, skirtu klaviatūros, kalbos ir prieinamumo darbo eigoms

Syntax

function FocusedFormFieldText: WString;

Return Value

WString. Tekstas, kurį pateikia šiuo metu sufokusuotas formos valdiklis, arba tuščia eilutė

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

API names, type names, and PDF terms keep their original spelling so code search remains reliable
Call the member only after the owning document or viewer is active unless the syntax describes an event or design-time property

Example

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