Of coarse here is a test program showing the bug
extern crate web_view;
use web_view::WebView;
use web_view::MyUnique;
use web_view::Content;
use web_view::Dialog;
use web_view::Alert;
use web_view::run;
const HTML: &str = r#"
<DOCTYPE html>
<html>
<body>
<button onclick="window.external.invoke('open')">Open File Dialog</button>
<button onclick="window.external.invoke('save')">Save File Dialog</button>
<button onclick="window.external.invoke('directory')">Choose Directory Dialog</button>
<button onclick="window.external.invoke('alert-info')">Info Alert</button>
<button onclick="window.external.invoke('alert-warning')">Warning Alert</button>
<button onclick="window.external.invoke('alert-error')">Error Alert</button>
</body>
</html>
"#;
fn callback(view: &mut WebView<()>, arg: &str, user_data: &mut ()) {
match arg {
"open" => {
println!("Attempting to open 'OpenFile' dialog");
view.dialog(Dialog::OpenFile, "Test Open Dialog", "");
},
"save" => {
println!("Attempting to open 'SaveFile' dialog");
view.dialog(Dialog::SaveFile, "Test Open Dialog", "");
},
"directory" => {
println!("Attempting to open 'ChooseDirectory' dialog");
view.dialog(Dialog::ChooseDirectory, "Choose Directory Dialog", "");
},
"alert-info" => {
println!("Attempting to open info alert");
view.dialog(Dialog::Alert(Alert::Info), "Info Alert", "");
},
"alert-warning" => {
println!("Attempting to open warning alert");
view.dialog(Dialog::Alert(Alert::Warning), "Info Alert", "");
},
"alert-error" => {
println!("Attempting to open error alert");
view.dialog(Dialog::Alert(Alert::Error), "Info Alert", "");
}
_ => {}
}
}
fn main() {
let (_, _) = run("open dialog test",
Content::Html(HTML),
Some((500, 500)),
true,
true,
|_|{},
callback,
()
);
}All of the alerts work so ignore those, but none of the file dialog's ever open

Not sure, I only have Win 8.1.
Do you have a minimal test example that exhibits the same behavior?
Maybe someone who also has Win 10 can test this..

This is the strangest thing, in order to debug this, I tried to put some debug prints into original c webview source code. With the printf statements in, everything works, when I comment them out, it does not work.

@Zxey I got fed up with Windows and installed Ubuntu at work so i no longer have the means to work on this.
After reading that I think it has something to do with building webview in the build script of the webview-sys crate. Maybe something isn't getting linked correctly? I am very new to C so maybe that's a stupid question. But if there is anything i can do to help debug let me know!

I found that that it does not work for me when i build webview in debug mode, but it works when i build it with release mode.

Seems like it is uninitialized variable in webview in c code.

Created PR in original webview library. Should be fixed when webview/webview#214 gets merged upstream. We can then update our submodule and get the fix.

This also happens to me on Window 10, but only on the stable-msvc toolchain. Dialog functions normally when built on the stable-gnu toolchain.
nvm, still having the same problem.
