WebView Doesn't Work in Compiled Plugins and Stand-alone Apps

clevername27

@dxmachina @Christoph-Hart I did manage to get it working for external websites. On macOS (I don't have Windows or GNU/Linux), it works flawlessly. I'll mark as solved.

dxmachina, this goes somewhere in your script; the component is the HISE web browser.

const var web_DOCS_CoreHTML_GUI = Content.getComponent("web_DOCS_CoreHTML_GUI");

// ------------- CoreHTML Stuff

// This file has the redirect to the internet.
var startingPage = FileSystem.getFolder(FileSystem.AudioFiles).getParentDirectory().getChildFile("Images/html/index.html");

web_DOCS_CoreHTML_GUI.set("enableCache", true);
web_DOCS_CoreHTML_GUI.reset();
web_DOCS_CoreHTML_GUI.setIndexFile(startingPage);

And then the html file, use a meta-tag to redirect:

<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>Plugin Build Information</title>
<meta http-equiv="refresh" content="0; URL=https://www.hise.dev" />
<style>
h1, h2, h3 {
	color: #9b64d0;
}
</style>
</head>
<body>
</body>
</html>

@clevername27 that's a cool trick, thanks!

dxmachina

@clevername27 Thank you.

Just for clarity, in case anyone else is making rookie mistakes like myself. The main issue for me (just using embedded webview) was:

WebView1.set("enableCache", false);

This had to be set to true in builds or you otherwise end up with just a blank webview in your app/plugins. To be fair, this is in the docs.

@dxmachina Hi, I have tried both Enable cache and Disable cache. Everytime it is ended with White.

Sometimes HISE unable to compile. I had to reload the project > Enable cache . Disable cache to get rid off the error something "external file"

Error. Not being compiled.

@DabDab Does that mean you've solved the issue, or that you've pin-pointed it?

DabDab

@clevername27 I am confused, when I am enabling cache false by

WebView1.set("enableCache", false);

It is being compiled but DAW not showing the plugins. Only White Canvas Webview.

And when I enable cache to true

WebView1.set("enableCache", true);

it ends up with the above error.

getting the same issue as @DabDab

dxmachina

@DabDab @Adam_G

I have no issue compiling my plugin with webview on Mac/PC.

I'm wondering is this related to the specific example you're trying to compile? I have not attempted to compile the example preset browser.

Maybe just try a simpler test with some html/css and a binding?

DabDab

@dxmachina Can you send me your Example Snippet ?

Adam_G

@DabDab did you ever get a resolution for this? my webview is working on one computer but not the other with seemingly the same setup. im a bit lost haha

DabDab

@Adam_G I have updated to the latest commit where I am having same Webview White Box in Compiled plugins. Additionally there is no CSS Auto completion and suggestion. I don't know what's going on.
