Re: [Gretl-devel] help files

Here's an update on the status of clicking on a link to the (PDF) User's Guide in the GUI help text. The precise effect depends on the platform and the PDF viewer. There are two questions: 1) Does the platform/viewer support opening the PDF at a specified "named destination" at all? 2) If so, what happens on a second click on a GUI help-text link, pointing to a different chapter: will the viewer obligingly update the read position in the PDF file, or do you only get one shot? Linux: evince: Yes on question 1, and Yes on the update in question 2. xpdf: Yes on question 1; opens a new window in re. question 2. okular: Supposed to be Yes on question 1, according to the docs; I don't know about question 2. (I'm not in a position to test.) other viewers: I'm not aware of any others that will cooperate. Windows: Adobe Acrobat/Acrobat Reader: Yes on 1, and also Yes on updating the viewing position now that I've added some DDE code (in git and snapshots). other viewers: I'm not aware of any others that will cooperate. Mac: Nothing doing, so far as I can see. I can't get Adobe products to do anything useful, nor the native Apple Preview.app. I can't find any relevant documentation. I did try a few experiments aimed at Acrobat Reader DC, but to no effect. Allin
