本文实例为大家分享了python图形用户接口实例的具体代码，供大家参考，具体内容如下

运用tkinter图形库，模拟聊天应用界面，实现信息发送.

from tkinter import *
import time
def main():
 #发送消息
 def sendMsg():
 strMsg = '我：'+ time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())+'\n'
 txtMsglist.insert(END,strMsg,'greencolor')
 txtMsglist.insert(END,txtMsg.get('0.0', END))
 txtMsg.delete('0.0',END)
 #键盘发送消息
 def senMsgKeyboard(event):
 if event.keysym == "Up":
  sendMsg()
 #取消发送
 def cancelMsg():
 txtMsg.delete('0.0', END)
 #窗口定义
 t = Tk()
 t.title("聊天窗口")
 # 页面布局
 # 创建frame容器
 frmLT = Frame(width=500, height=320, bg='white')
 frmLC = Frame(width=500, height=150, bg='white')
 frmLB = Frame(width=500, height=30)
 frmRT = Frame(width=200,height=500)
 # 创建控件
 txtMsglist = Text(frmLT)
 txtMsglist.tag_config('greencolor', foreground='#008C00')
 txtMsg = Text(frmLC)
 # 键盘发送消息
 txtMsg.bind("<KeyPress-Up>", senMsgKeyboard)
 # 按钮发送消息
 btnSend = Button(frmLB, text='发送', width=8, command=sendMsg)
 btnCancel = Button(frmLB, text='取消', width=8, command=cancelMsg)
 imageLink = PhotoImage(file = "test.gif")
 lblImage = Label(frmRT, image=imageLink)
 #控件布置到页面
 frmLT.grid(row=0, column=0, columnspan=2, padx=1, pady=3)
 frmLC.grid(row=1, column=0, columnspan=2, padx=1, pady=3)
 frmLB.grid(row=2, column=0, columnspan=2)
 frmRT.grid(row=0, column=2, rowspan=3, padx=2, pady=3)
 # 固定大小
 frmLT.grid_propagate(0)
 frmLC.grid_propagate(0)
 frmLB.grid_propagate(0)
 frmRT.grid_propagate(0)
 btnSend.grid(row=2, column=0)
 btnCancel.grid(row=2, column=1)
 lblImage.grid()
 txtMsglist.grid()
 txtMsg.grid()
 # 主事件循环
 t.mainloop()
if __name__ == '__main__':
 main()

界面效果如下：
