省时省力！这大概是用Python写到GUI最快的方式了！

调试一下，刚才视觉效果：

这是一个带历史记录的聊天该软件，如果你所需花钱一个值得注意的该软件的话，可以实际上镜像预定义，然后大大的删改一下。

接口大全

我们便来看一个举例：

#!/usr/bin/env python

"""

Example of (almost) all Elements, that you can use in PySimpleGUI.

Shows you the basics including:

Naming convention for keys

Menubar format

Right click menu format

Table format

Running an async event loop

Theming your application (requires a window restart)

Displays the values dictionary entry for each element

And more!

我们来刚才调试之后的视觉效果：

这个 demo 是 PySimpleGUI 所有接口的等价，每一个 tab 都是一个类群。这里包括进度条、画布、意念、滚动条等等。如果你想要回来界面接口，到这个 demo 的程式库里回来就对了。

揭示

这里还有更多程序当中，大家就自己去冒险吧！这里主要是给大家介绍一个极加速开发 GUI 的步骤，俗称CV乾坤。不过这只是一种极加速开发方式，大家有等待时间还是去刚才程式库，了解一下定律相比较好！

大家有什么所需阐释的，可以在评论第一区电邮！
