I had a look at the examples about ColumnText. I tried to make a simple
application using them. I encounter a strange problem. Here is the code :
ColumnText ct = new ColumnText(cb);
Phrase phr=new Phrase("Some text.\n\n", FontFactory.getFont(
FontFactory.HELVETICA, 12));
ct.addText(phr);
float[] left1 = {56,790, 56,52};
float[] right1 = {483,790, 483,52};
ct.setColumns(left1, right1);
ct.go(true);
ct.go();
If I try to simulate to add a Phrase, it'll never add anything after this,
even if I use ct.go(). Is my code wrong ?

No.

You add the ColumnText in 'simulation mode'.
Meaning you 'pretend' to add the content in
order to get information about:
- the number of lines,
- the Y position,
- ...
If these values are OK to you, you add the
content to the ColumnText again, and you
decide if you add it to the current page,
or the next page.
This is all explained in chapter 7 of the book.
