PDF XChange Forum

Hi,

May I ask how to catch the information of a link when clicking it? The information includes destination file name, link type, target page number and etc.

Thanks.
Yi

Hello Yi,

When clicking on the link annotation, the action list is being executed. Before the execution the e.document.beforeRunAction event is being executed:
https://sdkhelp.pdf-xchange.com/vi ... eRunAction
You can obtain the IPXV_DocActionEvent from it, where the ActionData property stores the IPXC_Annotation (in case of the link). To check the type of the ActionData, the TriggerClass should be used - in this case, the PAEC_Link class should be specified.

Cheers,
Alex

Hi Alex,

Can I have a sample code for retrieving the link information when clicking on it in Delphi programming language?

Thanks.
Yi

Hello Yi,

I do not believe there are any Delphi examples for this available, however you can find all sample, descriptions, and other useful tidbits from our GitHub: https://github.com/tracker-software
There are a number of Delphi examples in of both the Delphi sections, and under some of the other larger sections as well.
I hope this helps!

Hi Daniel,

I've checked all the Delphi examples on your Github. Unfortunately, I could not find any information referenced to how to get a link's properties. Do you have any samples in any programming language for retrieving a link's information?

Thanks.
Yi

Hello Yi,

1) There is a sample on how to catch events in the FullDemo application.
2) There also is a code sample, on how to cast e.pEvent to the needed interface.
3) Here's an event interface description: https://sdkhelp.pdf-xchange.com/vi ... ctionEvent
4) I've explained everything else that should be done with the data, available from that interface in my previous post.

Cheers,
Alex

Hi Alex,

Thanks for the information. Is the code sample mentioned in "2) There also is a code sample, on how to cast e.pEvent to the needed interface." still in the Fulldemo application?

Best Regards,
Yi

Hello Yi,

Of course - it's on the top of the method (commented piece of code).

Alex

Hi,

I did a test and noticed that the OnEvent() not triggered when clicked on a link. Please see the attached screenshot to confirm if I was using the correct event procedure.
Thanks.
Yi

Hello Yi,

If you had watched the FullDemo application closely, you would see that the needed events are added in the IDS enum. And all of the events from the IDS enum are being registered for listening in the IPXV_Control by the https://sdkhelp.pdf-xchange.com/vi ... tListening method.

Cheers,
Alex

Hi Sasha,

Could you please provide a demo project to get all the information of a link when clicking on it? Once this resolved, I will purchase the PDF XChange SDK with no doubt.

Thanks.
Yi

Respectfully - the Editor SDK is not for novices or those with no fundamental understanding of the PDF Structure.

You are expected to have a working knowledge of the PDF standard and specification to be able to utilize our products fully. The PDF format is exceptionally complex and we to document or 'coach' developer's in everything necessary to work with the format in the correct manner. This is beyond the scope of the support that we, or any other PDF company offering SDK's (including Adobe), provide to customers.

We have endeavoured to point you in the right direction but we cannot write detailed code on your behalf - it would be uneconomic and impractical to so.


We do NOT supply sample projects for developer's on request.
