How to hyperlink text to a slide

[Johnson]

Hi,
Any one knows how to hyperlink text to a slide while creating the pptx. First I have the text and the slide is added later in the application.

Attached is the complete code that creates the text in a table and the slides.

I tried to create the Relationship

Code: Select all

if(i == 5){
                    org.docx4j.relationships.ObjectFactory factory = new org.docx4j.relationships.ObjectFactory();
                        org.docx4j.relationships.Relationship rel = factory.createRelationship();
                        rel.setType("Namespaces.PRESENTATIONML_SLIDE");
                        rel.setTarget("/ppt/slides/slide"+i+".xml");
                        mainPresentationPart.getRelationshipsPart().addRelationship(rel);
                        System.out.println(rel.getId());
                 }


and added code to link the text

Code: Select all

  + "<a:cs typeface=\"Times New Roman\"/>"
                                +"<a:hlinkClick r:id=\"rId8\" action=\"ppaction://hlinksldjump\"/>"
                            + "</a:rPr>

The code compiles fine. But when I open the files - says that it is corrupt and the slide is replaced with a blank one.

I am missing something. Not sure what it is.

Thanks
Johnson

By way of background, a hyperlink to a web page requires a relationship to be set up:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using xml Syntax Highlighting

            <a:r>
              <a:rPr lang="en-AU" dirty="0" smtClean="0">
                <a:hlinkClick r:id="rId2"/>
              </a:rPr>
              <a:t>docx4j forums</a:t>
            </a:r>

A hyperlink to the next slide has no explicit rel:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using xml Syntax Highlighting

             <a:r>
              <a:rPr lang="en-AU" dirty="0" smtClean="0">
                <a:hlinkClick r:id="" action="ppaction://hlinkshowjump?jump=nextslide"/>
              </a:rPr>
              <a:t>Next Slide</a:t>
            </a:r>
 

Parsed in 0.001 seconds, using GeSHi 1.0.8.4

(nextslide is special; looks like there would be similar short cuts for previous, first, and last).

Any other slide needs a rel to be set up:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using xml Syntax Highlighting

            <a:r>
              <a:rPr lang="en-AU" dirty="0" smtClean="0">
                <a:hlinkClick r:id="rId3" action="ppaction://hlinksldjump"/>
              </a:rPr>
              <a:t>slide 3</a:t>
            </a:r>

So you are on the right track.

Two things:

1. looks like you are adding the rel to mainPresentationPart; you need to add it to the slide you are putting the hyperlink on.
2. check that you are adding the right relId (you have rId8 hard coded).

Jason,

It is working perfect. The attached java file has the complete code. It might save someone's time.

Thank you for the beautiful library and the quick support.

Cheers...
