How to align AcroFields?

I'm using iText to populate the data to PDF templates, which are created in OpenOffice. The form is populating fine; I'm getting proper PDF, but I want to change the alignment of some fields.

I am using the following code.

fields.setFieldProperty(fieldName, "fflags", PdfFormField.Q_LEFT, null);

The quadding isn't part of the field flags as you wrongly assumed. It's and entry of the widget annotation dictionary. This is how you change it:

AcroFields form = stamper.getAcroFields();
AcroFields.Item item;
item = form.getFieldItem("fieldLeft");
item.getMerged(0).put(PdfName.Q, new PdfNumber(PdfFormField.Q_LEFT));
item = form.getFieldItem("fieldCenter");
item.getMerged(0).put(PdfName.Q, new PdfNumber(PdfFormField.Q_CENTER));
item = form.getFieldItem("fieldRight");
item.getMerged(0).put(PdfName.Q, new PdfNumber(PdfFormField.Q_RIGHT));

See the AlignField method for the full example.
