Webview cant find index file.....Help please.

@Chazrox Also, this from the docs might apply:

If you want to load images, you will most likely use files from the Images subdirectory. HISE is smart enough to assume this too. This means you can (and must) omit Images/ from the path string.

@dannytaurus I got it to load. Im just trying to figure out how to get the button to trigger what 'Enter' with a button press for the webview. Try this snippet if you have a minute, and press 'Enter'.

@Chazrox Sweeeeeettt!

[VirtualVirgin]

@Chazrox Nice! I've been looking into the WebView recently and I'm preparing to put it into my projects.

[Chazrox]

@VirtualVirgin What are you using to create your web UI? I just found Spline and it lets you create all these 2D/3D shapes and events and create variables for which we can read/write to in Hise. Interesting thing I want to learn about webview is the api's and webooks for some extracurricular activities lol Im learning about that rn, I'll post something back on this thread when I figure something out.

@Chazrox said in Webview cant find index file.....Help please.:

@dannytaurus I got it to load

How did you get it to load by the way?

EDIT: found it in your snippet:

const var f = FileSystem.getFolder(FileSystem.AudioFiles).getParentDirectory().getChildFile("Images/untitled/index.html");

[Chazrox]

@dannytaurus I found the example from the tutorials and just swapped the file honestly. I had to learn how to hook up the button to trigger the animations on the webview with some help from gpt.

I found an app called Spline and it lets you make shapes and animations with variables that you can hook up to stuff. This is all brand new to me but im slowly getting it. Have you heard of Spline or do you use something equal or better?

[dannytaurus]

@Chazrox I'm only using a WebView for some simple credits text at the moment. See here: https://forum.hise.audio/post/114297

I have a pretty solid HTML/CSS background so it's a very easy fallback for me, but it still feels weird using HTML/CSS in a plugin!

[VirtualVirgin]

So I was looking into the possibility of doing all UI with the WebView, but it turns out that going this route incurs a large overhead penalty for RAM, possibly even taking up 500MB of RAM for each instance of the plugin. Given that I am making MIDI plugins and plan for use cases where there are many instances going, this is a no-go for me. I don't want to to be using 10x the amount of memory just for having a slightly nicer UI. Has anyone else experienced this?

[Chazrox]

@VirtualVirgin whaaa 500mb?? Its take alot for a normal browser window to hit that much ram. What does ur plugin do?
