Access Forms

Retrieves all form widgets on the current page.

This method fetches all form widgets present on the current page of the PDF document and returns a list of corresponding CPDFWidget instances.

const pdfReaderRef = useRef<CPDFReaderView>(null);

<CPDFReaderView
  ref={pdfReaderRef}
  document={samplePDF}
  configuration={ComPDFKit.getDefaultConfig({})}
/>

// Get the total number of pages in the PDF document
const pageCount = await pdfReaderRef!.current!._pdfDocument.getPageCount();
let allWidgets: CPDFWidget[] = [];
for (let i = 0; i < pageCount1; i++) {
  // Retrieve the page object for the corresponding page number
  const page = pdfReaderRef?.current?._pdfDocument.pageAtIndex(i);
  // Get all forms on the page.
  const widgets = await page?.getWidgets();
  if (widgets) {
    allWidgets = allWidgets.concat(widgets);
  }
}

Read Signature-Field State

CPDFSignatureWidget.isSigned is a read-only optional property. true means the field contains a digital signature; false means it is unsigned. Older bridges may omit this property. Treat an absent value as unknown, not unsigned.

When signing, use the page and uuid read from the current document. See Create Digital Signatures.
