Hi,

I am inquiring about whether there is any implementation of the above library in B4J and if it has a built-in viewer.

Regards

I'm using the same library (modified for ABMaterial) and my url looks like this:

./viewerpdf.html?file=../PDF/1.pdf

so myabe in your case you could try something similar?

file:/C:/temp/ViewerJS/index.html?file=file:/C:/temp/pdftest.pdf

@alwaysbusy Thank you for your response

I tried your syntax (file:/C:/temp/ViewerJS/index.html?file=file:/C:/temp/pdftest.pdf) against @Daestrum (file:/C:/temp/ViewerJS/index.html#file:/C:/temp/pdftest.pdf) but no luck so far.

It seems that putting the webview in a pane and using these lines of code is the problem
B4X:
webview2.PrefWidth=Pane2.width-25
webview2.PrefHeight=Pane2.height-25

They are returning the width and height of Pane2 as 0 (zero) therefore the webview is being resized to -25 x -25 so you cant see it.
(prefWidth and prefHeight also return 0)

I had to explicitly set the pane width and height when I added it to the rootpane (f1.rootpane.addnode(p1,0,0,600,600) before the webview was visible.

Is it possible to test opening a pdf directly in ViewerJS.html? If so, what will be the syntax?

if you have a pdf to try - then its
file:/C:/temp/ViewerJS/index.html#file:/where/your/pdf/file/is.pdf

I found the problem! But, partly solved.

Strangely, the file to be uploaded, pasting the link directly, must be in the insie the ViewerJS folder. The webview is still behind!

It seems the problem is not the webview object but file path issue. Now I do not know how to fix that.

The load method is built into javafx webengine, so can't do anything to that.

If I paste the address file:/C:/temp/ViewerJS/index.html#file:/C:/temp/pdftest.pdf directly into my browser it works as expected.

The pdf can be anywhere on my pc, I don't need it to be in the viewerjs directory.

It seems like I hit on a dead end road! I tried every thing in my capacity to fiddle with the code. Only a complete sample app can help.

Thanks to all who offered their help

This is the full code that I have been using. It has calling viewer directly and calling showpdffile(filename) to open a new window with a viewer in.

Thank you so much.

Unfortunately, the same situation exists. I must not doubt your code is function. Maybe I relax for some time and try again later.
