Attach to a parent window?

[adam-hanna]

In the audio production world, developers can build VST plugins. These plugins can have GUI's but need to attach the GUI to an externally managed window.

Is it possible to add a feature to this library to allow such functionality?

For example, here's a rust crate for vst gui's that opens a web view and attaches it to a parent window: https://github.com/vanderlokken/rust-vst-gui/blob/c71ca8df17bbfb2b109aa72ffc05bbf56e3aeadd/src/lib.rs#L56

Here's the maintaners thoughts on using this library for cross-browser support: https://github.com/vanderlokken/rust-vst-gui/issues/8#issuecomment-832985277

EDIT ACK! This has already been mentioned in the Readme! So Sorry!

I'm reopening this because we don't have a ticket for this yet.. It's probably possible but I'm not sure how. @vanderlokken: Would it be possible the same way as in https://github.com/vanderlokken/rust-vst-gui?

Just to add on usecases. I have an "old" application in Qt with two QtWebViews managed by that application – its basically just a convenience for managing two browser windows for the user for managing multiple accounts etc. But maintaining and deploying this application for Linux/macOS/Win is quite labor intense(Qt by itself and the Webview with openssl dependencies etc.) and i would love to replace it with something like fltk-rs and two embedded web-views. Would love if this could work like the embedded VLC example as an additional inspiration.

Also adding @mikesoylu to the thread who may be able to provide comment (he forked @vanderlokken's code to work with MacOS).

If i am not fully mistaken the underlying c-lib should already support that, no?

https://raw.githubusercontent.com/zserge/webview/master/webview.h

// Creates a new webview instance. If debug is non-zero - developer tools will
// be enabled (if the platform supports them). Window parameter can be a
// pointer to the native window handle. If it's non-null - then child WebView
// is embedded into the given parent window. Otherwise a new window is created.
// Depending on the platform, a GtkWindow, NSWindow or HWND pointer can be
// passed here.
WEBVIEW_API webview_t webview_create(int debug, void *window);

i tried digging through the code a little bit with webview_sys and wondering why this is so different from webview.h different version or handmade wrapper?

EDIT:
oh ... is https://github.com/Boscop/web-view/tree/master/webview-sys a fork/reimplementation of https://github.com/webview/webview and not a "generated" binding that tracks webview and the implementations have diverged?

EDIT2:
yeah its say in the Readme:
This library provides a Rust binding to the original implementation of webview, ...

and this https://github.com/webview/webview/blob/0.1.0/webview.h looks quite similar to the current implementation of webview_sys that does not have the same API as the example i showed above. There was a major refactoring it looks like.

Hi was able to do it with cocoa(just for some apple specific stuff) and webview-sys. Relevant code can be found here in the fork: https://github.com/mikesoylu/rust-vst-gui/pull/1/commits/3b56730f190e1907b60a2f41d4c9a968f228fcad#diff-7ea3d8f419ddb71f86b7e524c1c7025cf92f1b46ad6457e505795209408f67f1

I've done this but for a C++ plugins framework here. I don't know Rust but it should be possible to extract the webview classes and write a wrapper. The classes were written from scratch with all the plugin specifics in mind: no statics, no link to GUI toolkits, etc.

This reverb plugin has a webview based UI.

Hi! Any updates on this? It would be extremely helpful for writing UI in games :)
