Panic when add empty strings in listview about winsafe

[rodrigocfd]

You're probably trying to use WString as a buffer without initializing it.

Please provide some context.

I have written a piece of code that can reproduce this issue.

use std::error::Error;

use winsafe::{
    gui::{Horz, ListView, ListViewOpts, Vert, WindowMain, WindowMainOpts},
    prelude::*,
};

#[derive(Clone)]
struct MainWindow {
    window: WindowMain,
    list: ListView,
}

impl MainWindow {
    fn new() -> Self {
        let window = WindowMain::new(WindowMainOpts {
            size: (800, 600),
            ..Default::default()
        });

        let list = ListView::new(
            &window,
            ListViewOpts {
                position: (0, 0),
                size: (800, 600),
                resize_behavior: (Horz::Resize, Vert::Resize),
                columns: vec![("Column 1".to_owned(), 100), ("Column 2".to_owned(), 100)],
                ..Default::default()
            },
        );

        let window = Self { window, list };
        window.events();
        window
    }

    fn events(&self) {
        let list = self.list.clone();
        self.window.on().wm_create(move |_| {
            list.items().add(&["", ""], None); // <-- Here I try to add an item with empty strings, and it panicked.
            Ok(0)
        });
    }
}

fn main() -> Result<(), Box<dyn Error + Send + Sync>> {
    let main_window = MainWindow::new();
    main_window.window.run_main(None)?;
    Ok(())
}
