ComboBox work fine in preview
but crashed when you build and run from rust

  • Slint Version: 1.9.2
  • Platform/OS: Windows 11 22H2 22621.4317
  • Programming Language: rust v1.86.0-nightly msvc backend
  • Backend/Renderer: winit

is there something wrong with my environment or meet some bugs ?

app.slint

import { ComboBox, HorizontalBox } from "std-widgets.slint";
export component ParamEditor inherits Window {
    HorizontalBox {
        alignment: start;
        Text {
            text: "ABCD:";
        }

        hello := ComboBox {
            model: ["A", "B", "C", "D"];

        }
    }
}

main.rs

slint::include_modules!();
fn main() {
    let app = ParamEditor::new().unwrap();
    app.run().unwrap();
}

error message when click the combox

This bug was introduced in #7265, although it probably just uncovered a more general issue with focus and repeated elements or popups. I failed to report this earlier, sorry.

I'm curious to know what in both your environments make the AccessKit backend initialize. I don't get any panic if I run the gallery app and click on the combobox if I don't have my screen reader or screen magnifier on.

This is what happened when I tested with gallery app.

I am also seeing this exact problem when cross-compiling for windows on a Linux host using the x86_64-pc-windows-gnu target, the panic occurs as soon as I click a combo box. I'll note that it works fine with slint and slint-build v1.9.1.

I am guessing the above panic message will be enough to troubleshoot, but I can provide more details and/or an MWE if it would be useful.

It seems to be caused by shutting down services or streamlining window system , and does not exist on a fresh install of a full system.
Painc can be avoided by manually disabling the accessibility feature
maybe turn it off until the problem is found and fixed.

@agkyunromb Thanks for the tip. Disabling the accessibility works around the issue for me until it gets fixed.
