如何在“编辑器”窗口中以相同大小显示“检查器”窗口？

问题在于，在Inspector中看起来不错，但是在“编辑器”窗口中，控件和字段不在同一位置。

在屏幕截图中，“检查器”窗口位于右侧，“编辑器”窗口位于左侧。问题出在检查器上的“对话名称”上，“名称”字段紧随“对话名称”之后，但是在“编辑器”窗口中，“名称”字段似乎有点超出“对话名称”：

Conversation Name

这是我添加“对话名称”和“名称”字段的部分：

foldout.boolValue = EditorGUI.Foldout(new Rect(position.x, position.y, 10, EditorGUIUtility.singleLineHeight), foldout.boolValue, "Conversation Name ", true);
name.stringValue = EditorGUI.TextField(new Rect(position.x + 120, position.y, 244, EditorGUIUtility.singleLineHeight), name.stringValue);

这是“编辑器窗口”脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEditorInternal;
using UnityEngine;

public class ConversationsEditorWindow : EditorWindow
{
    private ConversationTriggerEditor editor;

    [MenuItem("Conversations/Conversations System")]
    static void Init()
    {
        const int width = 800;
        const int height = 800;

        var x = (Screen.currentResolution.width - width) / 2;
        var y = (Screen.currentResolution.height - height) / 2;

        var window = GetWindow<ConversationsEditorWindow>();
        var ff = FindObjectOfType<ConversationTrigger>();
        window.position = new Rect(x, y, width, height);
        window.editor = (ConversationTriggerEditor)Editor.CreateEditor(ff);
