虽然使用 simplesialog.askstring 很好，但我想调整弹出窗口的大小并调整文本输入的宽度。
（示例代码）
from tkinter import *
from tkinter import simpledialog
prompts = ["name", "age", "height", "wheight"]
root = Tk()
for p in prompts:
answer = simpledialog.askstring(p, root)
print(answer)
我查看了不同的文档，但似乎无法找到如何做到这一点。

在我的 Simpledialog 中向按下的方法添加快餐栏时，我遇到了下面的错误代码。[Scaffold.of() 在不包含 Scaffold 的上下文中调用。]
我想就如何提供正确的上下文来解决它寻求您的建议。
import 'package:flutter/material.dart';
void main() {
runApp(new MaterialApp(home: new AlertApp()));
}
class AlertApp extends StatefulWidget {
@override
_AlertAppState createState() => _AlertAppState();
}
class _AlertAppState extends State<AlertApp> {
SimpleDialog _simdalog;
void sDialog(){
_simdalog = new SimpleDialog(
title: new Text("Add To Shopping Cart"),
children: <Widget>[
new SimpleDialogOption(
child: new Text("Yes"),
onPressed: (){
final snackBar = SnackBar(content: Text('Purchase Successful'));
Scaffold.of(context).showSnackBar(snackBar);
},
),
new SimpleDialogOption(
child: new Text("Close"),
onPressed:() {Navigator.pop(context);},

现在我有一个名为 ListVessel 的有状态页面。此页面包含来自数组 otherVessels 的 listTile。
下面是这个页面的代码。
class ListVessel extends StatefulWidget {
final Function() notifyParent;
ListVessel({Key key, @required this.notifyParent}) : super(key: key);
@override
_ListVesselState createState() => _ListVesselState();
}
class _ListVesselState extends State<ListVessel> {
@override
Widget build(BuildContext context) {
return ListView.separated(
separatorBuilder: (context, index) => Divider(color: Colors.blueGrey),
itemCount: otherVessels.length,
itemBuilder: (context, index) {
return ListTile(
title: Text("Name: "+otherVessels[index]["shipName"]),
onTap: () {
showDialog (
context: context,
builder: (_){
return otherTap(idx:index);
}
);
}
);
},
);
}
}
