I saw some new fancy stuff in the repo. Are we getting a webview in HISE?

@d-healey It's a helper class that seamlessly integrates with Juce based projects (if I understand it well)

@d-healey Ohh I've just seen the webview helper so I understand your question better now...

[Christoph Hart]

Ah damn it, I was extra sneaky with the commit message... stay tuned

Its vagueness made me curious

Alrighty, I think it's ready now for you all to play around:

HISE features now an embedded web browser that allows you to render parts of your UI using the native browser on the OS. The amount of possiblilities that this is unlocking is completely ridiculous, but I've added a project to the repository that contains two interesting use cases (using the newest fancy 3D rendering powered by the OS browser and implement a custom preset browser using your web design skills):

https://github.com/christophhart/hise_tutorial/tree/master/WebViewTests

The communication between HiseScript and the WebView component is as straightforward as it can get - you can call JS functions from HiseScript and bind callable HiseScript objects to JS callbacks.

I'll write a reference documentation later, but the examples should provide enough information for you to dig yourself into that rabbit hole.

It currently works on macOS and Windows, but I don't know how to add the browser handle to the Linux UI, so David has to wait inside while the other kids have fun on the new playground

I think you have a typo
https://github.com/christophhart/HISE/blob/develop/hi_tools/hi_standalone_components/ChocWebView.cpp#L34

Should be lowercase, no? Maybe my compiler is just picky.

Is there a preprocessor definition I can use to prevent it trying to compile the choc webview stuff on Linux? because I'm getting a few errors related to it and since it's not implemented I rather just not have it bother me.

[Christoph Hart]

@d-healey what are the errors (besides the typo)?

@d-healey Alright, I've booted up Linux and removed those errors. Most of those errors were actually related to the new SNEX MIR Backend, but I've also just deactivated the choc header on Linux.

Unfortunately the integration on Linux seems to be more complicated than I thought (which is annoying because juce actually has a webview component that is already using almost the same API as the choc header, but I need a few special methods to call javascript etc which is not available for the juce web component.

[d.healey]

@Christoph-Hart I wonder if that's because Linux doesn't have a standard web browser, like Edge or Safari?

[Christoph Hart]

@d-healey no it uses the webkit framework that you have to link with your binary (but JUCE does that already for the existing web component).

It's frustrating because the parts are all there but I lack the overview on Linux to put it all together...

[d.healey]

@Christoph-Hart Ah I understand now. Just tried building and no errors this time thanks

[d.healey]

Seeing this message in the console with the latest build, not sure what it's referring to.

Master Chain:! DLL Library version mismatch: 0.1.0 vs. 0.2.0

[Christoph Hart]

@d-healey haha, no that's the Loris DLL library version mismatch error (I bumped the version counter and included a few more features), but now that you mention it, I might want to make it more verbose so that you don't need to guess what version number it's talking about...

Oh and to get rid of it, pull and recompile the loris toolbox library.
