Is it possible to catch click events?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,
Does anyone know if it's possible to catch mouse click events within a PDF document? Specifically bookmark and/or hyperlink clicks?
If click event handling is indeed possible, is it done natively or does it require a complicated workaround? Could it be done within a C# application?
I'm looking to handle a schematic PDF with hundreds of bookmarks in a relatively simple hierarchy.

Thanks,
DK

	I think that the PDF Viewer Active-X SDK can do this, but I do not use it myself; I only use the Quick PDF Library. Certainly it is technically possible to do with PDFium, because you can go to a bookmark, and you can find the details of a link at an X/Y position in a PDF page, and Windows will tell you where you have clicked the mouse over the image. You just need to write an event handler.

	Hi DK, pdf is for layout - not for events but ... QuickPDF offers functionalities to embedd javascript to react on events in the document like onLoad or onClick. Perhaps this could feed your needs? Cheers and welcome here, Ingo (back from holidays ;-)
