Hi Emanuele,

I have added a custom property, for example "ABC" and also relative methods like setABC and getABC.
So while I'm creating a new annotation (PDFAnnot object) I want to set the value of "ABC" as part of PDFAnnot class and retrieve it later.
Right now i see just 2 properties in the class PDFAnnot and they are PDF_ANNOT m_handle and PDF_PAGE m_page. I want to add my property over here.

ok, as you can see in the PDFAnnot implementation, the annot informations are retrieved using library methods, that can read/write the annotation stored in the pdf file.
If you want to add custom properties, you have to use existing library methods to set/get values.

Thanks Emanuele!

Also please if you can specify which are the properties or get/set methods which are currently unused by RadaeePDF, so that any changes made by me should not affect the internal code.

Hi,

You can modify the demo project as you prefer.
You can create new methods or make changes; in the second case, I suggest to search in the project where the method is used.
