[iText-questions] Need help on 'SimpletextTreeNode' to construct tree structured content

[Umashanker Sivagurunathan -X (usivagur - HCL at Cisco)]

Hi,

 

Can we create a PDF with tree structured content using SimpletextTreeNode using iText ? If so, plz let me know if you have any example how to use the same.

How it will differ from List ?

I could not find any guide that describe the same.

 

 I tried it as follows and I could not be able to proceed further.

========================================

   document.open();

 
   Paragraph p1 = new Paragraph("p1");
   Paragraph p11 = new Paragraph("p11");
   Paragraph p12 = new Paragraph("p12");
   Paragraph p121 = new Paragraph("p121");
   SimpletextTreeNode tree1 = new SimpletextTreeNode(p1);
   SimpletextTreeNode tree11 = new SimpletextTreeNode(p11);
   SimpletextTreeNode tree12 = new SimpletextTreeNode(p12);
   SimpletextTreeNode tree121 = new SimpletextTreeNode(p121);
  
   tree1.add(tree11);tree1.add(tree12);
   tree12.add(tree121); 

========================================

 

How to add the root node (tree1) to the document ? Any casting needed?

 

Thanks
