java.lang.Object com.lowagie.text.pdf.PdfPTable org.ujac.print.tag.acroform.FloatingFormElement
public class FloatingFormElement
This class is an enhancement to the iText libary. iText doesn't support the
relative placement of form elements. This class is a workaround: We place a
table in the size of the desired form element in the document and register a
PdfPCellEvent listener. The listener is called when the table is positioned
in the document. We change the position of the form to the position of the
table. That this works we need to use the following order:
Create a form element:
TextField tf = new TextField(pdfWriter, new Rectangle(x, y, x + width, y + height), fieldName);
...do the layout of field...
Create the FloatingFormElement:
FloatingFormElement element = new FloatingFormElement(tf.getTextField(), pdfWriter);
Add the form element to reserve a place:
document.add(element);
The annotation is added automaticly.
