egui-modal，egui 的模态库 egui

常规使用

/* calling every frame */

let modal = Modal::new(ctx, "my_modal");

// What goes inside the modal
modal.show(|ui| {
    // these helper functions help set the ui based on the modal's
    // set style, but they are not required and you can put whatever
    // ui you want inside [`.show()`]
    modal.title(ui, "Hello world!");
    modal.frame(ui, |ui| {
        modal.body(ui, "This is a modal.");
    });
    modal.buttons(ui, |ui| {
        // After clicking, the modal is automatically closed
        if modal.button(ui, "close").clicked() {
            println!("Hello world!")
        };
    }); 
});

if ui.button("Open the modal").clicked() {
    // Show the modal
    modal.open();
}

对话框使用

在某些用例中，可能更方便一次性地将模态作为对话框打开和样式化，例如在函数返回的单例中。

/* calling every frame */

let modal = Modal::new(ctx, "my_dialog");

...
...
...

// Show the dialog
modal.show_dialog();

其他地方，

/* happens once */
if let Ok(data) = my_function() {
    modal.dialog()
        .with_title("my_function's result is...")
        .with_body("my_function was successful!")
        .with_icon(Icon::Success)
        .open()
}
