Crash when opening a dialog in connection with app.on_... (callback method )

[dirkeinecke]

Hi!

If a dialog is opened within a callback method of a UI checkbox and then closed (using the X button on the dialog), the app crashes. However, if I use the dialog outside the callback method, everything works fine.

What could be causing this issue?

Example (simplified):

app.on_deactivate_registration_file(move|| {        
    let dialog: InfoDialog = InfoDialog::new().unwrap();
    _ = dialog.show();
});

By crash, you mean panic? What's the panic message?

Hi!

I have attached the crash log file (I added a .txt to the file name so I could upload it here). Does it contain the information you need?

Hi @ogoffart,

I’ve put together a simple test app that includes only the essential components.

MyApp.zip

When you launch the app and click the "Click me!" button, a dialog opens. If you close the dialog using the close button in the title bar, the app crashes.

I hope this example helps clarify the issue and makes it easier to track down the problem.

Best regards,
Dirk

I tried your app and didn't get any issue. (I was on Linux/X11, i tried both the Qt and winit backend)

On what platform are you on?

I use macOS (Apple M1).
