receive_thread = threading.Thread(target=receive_message) receive_thread.start()

这是一个 Python 代码段,用于创建一个新线程并启动 `receive_message` 函数。其中 `target` 参数指定要在新线程中执行的函数,即 `receive_message`。`receive_thread.start()` 表示启动新线程,开始执行 `receive_message` 函数。这样做的目的是在一个独立的线程中进行网络消息的接收和处理,避免阻塞主线程。

主要修改如下:
1. 定义了字典dic,将表情标识符与表情图片一一对应。
2. 修改了send_mark函数,将表情图片对应的标识符放在消息中一起发送。
3. 修改了bb1、bb2、bb3、bb4、bb5函数,调用send_mark函数发送表情。
4. 修改了express_board函数,打开表情面板时,创建表情图片对应的按钮,并将其放置在窗口上;关闭表情面板时,销毁这些按钮。
5. 修改了receive_message函数,处理接收到的消息中包含表情标识符的情况,在消息框中创建表情图片。

当您滑动半圆形进度条时,您需要将进度值转换为数字,并将其发送到服务器上。为此,您需要修改 "HalfCircleProgressBar" 类的 "set_value" 方法,以便在进度值改变时发送数字。
以下是修改后的代码:
```
import tkinter as tk
import math
import socket
import threading
class HalfCircleProgressBar(tk.Canvas):
def __init__(self, master, radius, *args, **kwargs):
super().__init__(master, *args, **kwargs)
self.radius = radius
self.arc_start = 90
self.arc_extent = 0
self.create_arc(self.coords(), start=self.arc_start, extent=self.arc_extent, style=tk.ARC, width=10)
self.bind('<B1-Motion>', self.set_value)
self.socket = None
self.out = None
def coords(self):
x0 = y0 = self.radius
x1 = y1 = self.radius * 3
return x0, y0, x1, y1
def set_socket(self, host, port):
self.socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.socket.connect((host, port))
self.out = self.socket.makefile(mode='w')
def set_value(self, event):
x, y = event.x, event.y
cx, cy = self.coords()[0], self.coords()[1]
if x <= cx:
self.arc_start = 180
else:
self.arc_start = 0
self.arc_extent = int(math.atan((cy - y) / (x - cx)) * 180 / math.pi)
if self.arc_start == 180:
self.arc_extent += 180
self.delete("all")
self.create_arc(self.coords(), start=self.arc_start, extent=self.arc_extent, style=tk.ARC, width=10)
percentage = int(self.arc_extent / 180 * 100)
if self.out is not None: # Send value to server
self.out.write(str(percentage) + '\n')
self.out.flush()
root = tk.Tk()
progress_bar = HalfCircleProgressBar(root, radius=50, width=100, height=100)
progress_bar.pack()
def receive_message():
while True:
try:
message = progress_bar.socket.recv(1024).decode('utf-8')
progress_bar.update_message(message)
except ConnectionAbortedError:
break
def connect_to_server():
host = 'localhost' # Replace with your server host
port = 8000 # Replace with your server port
progress_bar.set_socket(host, port)
threading.Thread(target=receive_message).start()
tk.Button(root, text="Connect", command=connect_to_server).pack()
root.mainloop()
```
在这个例子中,我们将 "HalfCircleProgressBar" 类稍作修改,使其能够与服务器进行通信。在 "set_socket" 方法中,我们创建了一个新的套接字并连接到服务器上。在 "set_value" 方法中,我们将进度值转换为数字,并将其写入套接字中发送到服务器上。在 "receive_message" 函数中,我们从服务器接收消息,并将其传递给 "HalfCircleProgressBar" 类的 "update_message" 方法来更新消息。
在主函数中,我们创建了一个 "HalfCircleProgressBar" 对象并将其添加到主窗口中。我们还创建了两个函数: "connect_to_server" 和 "receive_message"。当用户单击 "Connect" 按钮时,我们调用 "set_socket" 方法来连接到服务器上,并启动一个新的线程来接收从服务器发回的消息。
请注意,这个例子中的服务器连接代码是一个简单的示例,您需要根据自己的需求来修改。
