Tkinter 是 Python 的标准 GUI 库。Python 使用 Tkinter 可以快速的创建 GUI 应用程序。

由于 Tkinter 是内置到 python 的安装包中、只要安装好 Python 之后就能 import Tkinter 库,对简单图形界面的实现十分简单。

在引入"import tkinter"后即可使用,以下两行即可运行出窗口,

loop = tkinter.Tk()  # 定义tk的实例

loop.mainloop()  # 运行窗口

但我们的需求肯定不止如此,通过使用tkinter自带的方法才能创造实际可用的窗口。

以下方法仅能规定窗口的大小的因素。

loop.title('窗口名')  # 定义窗口的窗口名
loop.geometry('300x120+600+210')  # 300x120定义窗口的大小
                                                       #+600+210定义窗口的位置
loop.resizable(width=False, height=False)  # 不可修改窗口大小

窗口的内容需要使用控件进行绑定,如:

 btn=Button(master=root, width=6, height=2)   # 意为定义一个按钮在root窗口中,宽为6,高为2

当然button还有许多其它的属性,如:

command 按钮关联的函数,当按钮被点击时,执行该函数;text 定义按钮的文本内容

下面是一个简易聊天客户室客户端代码,忽略掉socket和threading的内容即可:
