OK, the rect parameter is very important.
Create an implementation of the cell event interface.
For instance:
public class MyAnnotationCell implements PdfPCellEvent {
protected PdfWriter writer;
public MyAnnotationCell(PdfWriter writer) {
this.writer = writer;
}
public void cellLayout(PdfPCell cell, Rectangle rect,
PdfContentByte[] canvas) {
// to know what to put here, scroll down
}
}
Now when you have a PdfPTable, you can add PdfPCell objects.
One of those cells, annotationCell, needs to contain an annotation.
annotationCell.setCellEvent(new MyAnnotationCell(writer));
Because of the above line, iText will invoke the cellLayout() method,
as soon as the cell is drawn. This is why you need to put the code
to draw the annotation in the cellLayout method (where it says
"// to know what to put here, scroll down").

Skip to page 553.
In the cellLayout() method, you can put all the code from the line
"RichMediaAnnotation richMedia" until
"writer.addAnnotation(richMediaAnnotation);",
but don't forget to replace the hard-coded "new Rectangle(36, 400, 559,
806)" with
the rect parameter that is passed to the cellLayout() method.
Note that you have an instance of the writer, because you passed this object
when creating the cell event.
These are the simple principles.
It goes without saying that there's plenty of room for improvement.
For instance: you could replace the hard-coded RESOURCE and swf names
by membervariables of your cell event implementation. You can set these
variables in the constructor, or use setters.
I hope this helps.
