why my lineedit losses the focus

[Assassintears]

I'm a fresh man to use rust and slint. My code like this:

slint:

import { Button, VerticalBox, HorizontalBox , LineEdit, TextEdit, GroupBox} from "std-widgets.slint";

export component AppWindow inherits Window {
    preferred-width: 800px;
    preferred-height: 600px;
    title: "TCP Client";
    out property <string> IP;
    out property <string> Port;
    property <string> msg;
    callback signal_connect();

    VerticalBox {
        HorizontalBox {
            Button {
                text: "IP";
            }
            line_ip:= LineEdit {
                font-size: 14px;
                placeholder-text: "Enter IP address";
                text <=> IP;
             }
             Button {
                text: "Port";
            }
            line_port := LineEdit {
                font-size: 14px;
                placeholder-text: "Enter port number";
                text <=> Port;
            }
        }

        HorizontalBox {
            Button {
                text: "Connect";
                clicked => {
                    if (IP == "" || Port == "") {
                        msg = "Please input IP and Port";
                    } else {
                        msg = IP + ":" + Port;
                    }
                    line_recv.text += msg + "\n";
                    }
            }
            Button {
                text: "Disconnect";
            }
        }

        GroupBox { 
            title: "Recv Messages";
            HorizontalBox {
                line_recv := TextEdit {
                    font-size: 14px;
                 }
                 Button {
                    text: "Clear";
                    clicked => {
                        line_recv.text = "";
                    }
                 }
            }
         }

         GroupBox {
             title: "Send Messages";
             HorizontalBox {
                TextEdit { 
                    font-size: 14px;
                 }
                 Button {
                    text: "Send";
                 }
             }
         }
    } 
}

main.rs:

slint::include_modules!();
// use slint::SharedString;
pub mod client;
use client::tcp_client;

fn main() -> Result<(), slint::PlatformError> {
    let ui = AppWindow::new()?;

    ui.on_signal_connect({
        let ui_handle = ui.as_weak();
        move || {
            let ui = ui_handle.unwrap();
            let ip = ui.get_IP();
            let port = ui.get_Port();
        }
    });
    ui.run()
}

if I clicked show preview like bellow, it works well.

Well, if I run the code with cargo run, the mainwindow will dosnt work, the textedit widget will not be selected, and the button will not be clicked.

Well, It's not a problem, when I start the app, it works well after some seconds

Not sure I understand the issue. Is it that just that the window don't refresh (nothing changes)

What happens if you resize the window? May be related to https://github.com/slint-ui/slint/issues/5089 and https://github.com/slint-ui/slint/issues/5206

What would happen if you put a Spinner {indeterminate: true;} just to have an animation?

I'm sorry to reply you not in time. I mean I clicked the button, and the window dos not refresh

[ogoffart]

So it looks related to these two issues. (https://github.com/slint-ui/slint/issues/5089 and https://github.com/slint-ui/slint/issues/5206) We don't know what's causing this. I'd be very happy if you would help us debugging this. I don't know which of this is happening:

• The app is hanging (the main thread is blocked by something), a debugger would show the backtrace of what's hapenning
• Somehow a bug in Slint make it not see that it needs to be refreshed. (unlikely) A moving spinner would force the refresh and we'd see if that's the case
• The input are not processed at all and then all the event are delayed? Again a spinner which move but don't show the input would confirm this.

I'm going to assume this is the same as one of these issue and close this issue as duplicated

It's most likely an input method issue, when my computer defaults to English input everything works fine, but when my computer defaults to Chinese input , LineEdit doesn't get focus and can't type. Please configure your computer to use Simplified Chinese input method default initially and then start the program to test the effectiveness of LineEdit.
