就像插件的属性一样，因为这些插件都直接或间接继承了Widget类或者BaseWidget类，所以他们都有一些共同的方法。

所有组件的共有方法, 包括窗口

1. 配置Configuration

# grammar
# 1. 配置属性
# 等同于 w['option'] = value， 或在创建时设置
w.config(option=value)
# 2. 获取属性值
# 等同于，value = w['option']
value = w.cget("option")
# 3. 查看插件有哪些属性（key）
k = w.keys()
# 4. 查看当前的所有配置
print(w.config())

# example
import tkinter as tk
root = tk.Tk()
btn = tk.Button(root, text='click')
btn.config(bg='blue', fg='black')
btn.pack(side=tk.LEFT)

print(btn.cget('bg'), btn.cget('text'), btn['fg'])
print(btn.keys())
print(btn.config())
tk.mainloop()

2. 事件处理相关 Event processing

mainloop()
w.mainloop()
w.quit()
w.wait_variable(var)
w.wait_visibility(window)
w.wait_window(window)
w.update()
w.update_idletasks()

3. 事件回调函数相关Event callbacks

w.bind(event, callback)
w.unbind(event)
w.bind_class(event, callback)
w.bindtags()
w.bindtags(tags)

4. Alarm handlers and other non-event callbacks

id = w.after(time, callback)
id = w.after_idle(callback)
w.after_cancel(id)

5. 窗口管理Window management

w.lift(aboveThis=None)
w.lower(belowThis=None)

6. 窗口相关的信息 Window-related information

w.winfo_width()
# Get the width of this widget, in pixels. 
w.winfo_height() 
# Get the height of this widget, in pixels. 
w.winfo_reqwidth()
# Returns the “natural” width for this widget. The natural size is the minimal size needed to display the widget’s contents, including padding, borders, etc. 
w.winfo_reqheight()
w.winfo_id()
# Get a system-specific window identifier for this widget.
