New m1 troubles in code

[Emile_Schwarz]

Usually, when a project access to the hard disk (for images), macOS ask for permissions. But not this time.

The process runs in three times:
a. drop a folder onto a Canvas
b. press the Process pushbutton (look below)
the code scan the dropped folder contents, generate a valid html “file” stored in a TextArea;
c. That data can be saved to disk (Save As HTML PushButton)…

d. Rendered immediately: press the Render HTML PushButton in a nw window using an HTMLViewer.
The html links some images (.images/.png).
I also have an icon “To the Top” with each image.

I have a SelectFolder that ask me to choose the images location.

None of these are displayed; macOS ask me nothing.

Once saved, the TA contents (html file) works fine with any browser.

That project works fine with an MacBook Pro i5 / IDE and application.

Big Sur /M1:
Format(Item_Size, “## ###,###”)
Does not display the integert formatted as intended…
Works fine with the i5.

So a html file you load into HTMLViewer doesn’t show pictures?
How are those pictures referenced?

[TimStreater]

What OS you running on the i5? These days you have to ask permission to load local images for display. Even in Mojave.

Christian:
the html file is working fine when loaded in Firefox (or Safari).
I pass the TextArea.Text contents to the HTMLViewer.

[Emile_Schwarz]

Tim:
With the i5, the project works fine; the images appeared.

i5:
El Capitan / High Sierra
Xojo 2015r1.

M1: it does not ask for permissions (running in the IDE). This is probably because I use SelectFolder to get the images folder; then I load each image by name: Images_FI.Child("image1.png")

// Ask the user to choose the images folder
Data_FI = SelectFolder()

// Renders the document
wRender.HTMLViewer1.LoadPage(TA.Text, Data_FI)

but the files are not loaded.

No, Big Sur doesn’t ask, it just makes the HTMLViewer unable to load local images.

To solve this requires a method (using Declares) that came to me from @Sam_Rowlands but you should ask him if I can pass it to you.

[Sam_Rowlands]

I posted the declares somewhere, but you now need to ask the OS for permissions to display local HTML content.

New problem with HTMLViewer.LoadPage since Version 2020 R1

I believe that these are two different issues (although I may be incorrect). The one that I have tackled is the inability to load images from disk when passing in HTML code (it works with a HTML file on the volume). htmlViewer1.grantAccessToFolder( <folderContainingImages> ) htmlViewer1.loadPage( <htmlCodeAsString>, <folderContainingImages> ) For users of the Ohanaware App Kit, this code is already included, for everyone else copy and paste the following code into a shared module. Public Sub…

[TimStreater]

Emile, have a look at the link in Sam’s post above, it shows the required code. You would call it as:

wRender.HTMLViewer1.grantAccessToFolder (Data_FI.Parent)

(pretty sure you need the .Parent business.)

I must say I’m not sure why Apple or anyone might think that this has added extra, useful, security to macOS. Someone who knows how has added some Declares and - voila - we are back to where we were previously.

See also WKWebViewMBS class in MBS Xojo Plugins.

we have:

LoadFileURL(File as FolderItem, readAccessItem as FolderItem)

and you can put in the folder for the images there.

IT WORKS !

Thank you to Sam, Tim, Christian.

To the Xojo people:
When will you add a “Big Sur” Special Page with tips and tricks to run Xojo projects with “Big Sur” ?
(Next: do the same with “Monterey”)

PS: it is possible that I read that thread last year, but I have troubles to recall if I took my pills this morning, so remembering what I read one year ago is beyond… !
