开始默认勾选E2E报文，另外我要UI别的地方位置不变，最后两列channel和报文ID的填写框太靠右没对齐，帮我和他们和标签的位置对齐。另外在使用on message时，里面对应的如msg0x268这种报文名称需要在变量里面进行定义才能使用，请修正，如 message CAN_sub::CCU_1 msg0x268;，下面基于我下面小改的代码做修改：import tkinter as tk

下面是我的代码，请精度后按我的需求修改，在启用冗余环境后（非冗余全用IL_CAN1），我需要在UI上添加一个CAN总线配置，选择CAN1还是CAN2，即IL_CAN1还是用IL_CAN2，需要特别注意IL_CAN1::EnableAllNodes，IL_CAN1::EnableAllNodes_Main，IL_CAN2::EnableAllNodes_Sub这几个，IL_CAN1::EnableAllNodes不根据CAN总线改变，IL_CAN1::EnableAllNodes_Main前面根据CAN线配置，后面的根据冗余配置，IL_CAN2::EnableAllNodes_Sub同理。另外在ECU配置那里，添加判断是否为网关ECU，如果是，在生成输入项后，要判断每个报文是否有对应监听的网关报文，如果是有，需要选择位于channnel几，填写报文ID，用on message监听到对应channel上的对应报文后，用CAPL中的如IL_CAN1::CCU_1::ILMsgEnable控制关闭本ECU对该报文发送，复制改写监听到的报文名称为我们这条报文前面填写的名称，在本CAN线上发送（如参照示例：on message 0x7DF{if(this.msgChannel==1){msg7DF=this;msg7DF.can=2;output(msg7DF)}}）：import tkinter as tk from tkinter import messagebox, filedialog, ttk import os class CAPLScriptGenerator: def init(self, root): self.root = root self.root.title("CAPL Script Generator") window_width, window_height = 1000, 700 screen_width = root.winfo_screenwidth() screen_height = root.winfo_screenheight() x = (screen_width - window_width) // 2 y = (screen_height - window_height) // 2 root.geometry(f"{window_width}x{window_height}+{x}+{y}") main_frame = ttk.Frame(root, padding="10") main_frame.pack(fill=tk.BOTH, expand=True) style = ttk.Style() style.configure("Header.TLabel", font=("Arial", 12, "bold")) style.configure("Section.TFrame", relief="groove", borderwidth=2, padding="5") #
