Can LiveCode display PDF files on Mobile device?

Can LiveCode Read PDF files?

Thanks,

Hi David,

on macOS and iOS you can display PDF files in a browser object/widget right out of the box,
on Windows the Acrobat Reader web plug-in has to be installed on the target machine.

No idea about Android, sorry.

Klaus,

Where can I go to learn about using the browser widget?

I don't see it in the dictionary.

Thanks,

David

Hi David,

in the dictionary (LC >= select "Browser" in the popup menu on the topleft side "Choose API: ..."!

Basically you drag a browser widget to a card, set its height and width and just set its url to an internet url or:
...
put specialfolderpath("resources") & "/pdf_files/a_pdf.pdf" into tPDFFIle
## The neccessary trick:
replace SPACE with "%20" in tPDFFile
set the URL of widget "your browser widget name here" to tPDFFile
...
You get the picture.

Klaus,

Thanks for the help, but, I am not having any success.
There really is not much info on setting up the widget "Browser"

Would it be too much to give me a sample stack to view a PDF file?

Thanks,'

Hi David,

OK, here is a quick example.
Tested on my Mac and works with LC 9 dp4, but should of course work with all versions <= 8!

Klaus,

WOW!!

That works Beautifully!!

Now, I will spend some time studying it to see how you did it.

Thanks so MUCH,

David

Hi David,

you're welcome!
But this is really no rocket science!

Klaus,

My humblest apology. I should have mentioned that I was working on an IOS mobile app.

Your stack works great on desktop, but not on mobile.

Thanks,

David

Hm, try this:
1. add a PDF fle to the iOS standalone via the "Copy files" tab in the standalone builder settings
2. Use a little variation of my first script snippet:
...
put specialfolderpath("resources") & "/your_pdf_here.pdf" into tPDFFIle
## The neccessary trick:
replace SPACE with "%20" in tPDFFile
set the URL of widget "your browser widget name here" to tPDFFile
...
Should work on iOS, but maybe not in the simulator, which has some quirks, so they say...

Klaus,

I have tweaked your stack several ways, but could not get the mobile browser to display a PDF.
I have attached your stack with the changes that I made and also the pdf file that I
used.

Thanks for everyone's time and effort,

David

Hi David,

use -> specialfolderpath("resources")
This happens to be the same as -> specialfolderpath("engine") on mobile,
but might change in future versions, since the ENGINE folder is really TABOO for us!

AND specialfolderpath("resources") does also work in the IDE, it returns the folder where (current) stack resides,
so no need to use anything else during development! But that should not hinder your PDF from being displyed!

Add two SLASHES to the URL and try again:

Code: Select all

...
set the URL of widget "Browser" to ("file://" & tPdfFile)
...

Klaus,

Made recommended changes, but still does not work.

Thanks,

David

[Klaus]

Sorry, I do not develop for mobile, so no brilliant ideas in the moment...

[DR White]

Klaus,

Your insight is always appreciated.

Thank Again,

David
