tkinter ,wxPython,pyQT

1、
from tkinter import Label
widget=Label(None,text='Hello Gui')
widget.pack()
widget.mainloop()
2| expand fill：组件随窗口调整大小
from tkinter import *
widget=Label(None,text='Hello Gui')
widget.pack(expand=YES,fill=BOTH)
widget.mainloop()

file BOTH,Y,X

3、字典方式设置组件属性：

4、设置窗体标题

from tkinter import *
w=Button(None,text="tetxxx",command=sys.exit)
w.pack()
w.mainloop()
6、root.quit,side=LEFT

expand,fill

7、自定义回调函数：
import sys
from tkinter import *

def quit(): # a custom callback handler
print('Hello, I must be going...') # kill windows and process
sys.exit()

widget = Button(None, text='Hello event world', command=quit)
widget.pack()
widget.mainloop()
8、类方法

9、绑定鼠标事件：<Button-1> <Double-1> bind
import sys
from tkinter import *

def hello(event):
print('Press twice to exit') # on single-left click

def quit(event): # on double-left click
print('Hello, I must be going...') # event gives widget, x/y, etc.
sys.exit()

widget = Button(None, text='Hello event world')
widget.pack()
widget.bind('<Button-1>', hello) # bind left mouse clicks
widget.bind('<Double-1>', quit) # bind double-left clicks
widget.mainloop()
10、添加多个组件：Frame,Button,Label
from tkinter import *

def greeting():
print('Hello stdout world!...')

win = Frame()
win.pack(side=TOP, expand=YES, fill=BOTH)
Button(win, text='Hello', command=greeting).pack(side=LEFT, fill=Y)
Label(win, text='Hello container world').pack(side=TOP)
Button(win, text='Quit', command=win.quit).pack(side=RIGHT, expand=YES,fill=X)

win.mainloop()
11、fill 当窗体扩大缩小时，也跟着扩大缩小
12、anchor属性,N,NE,NW,S东西南北
13、自定义button类：self.init self.__config
from tkinter import *

class HelloButton(Button):
def init(self, parent=None, **config): # add callback method
Button.init(self, parent, **config) # and pack myself
self.pack() # could config style too
self.config(command=self.callback)

def callback(self):                                # default press action
    print('Goodbye world...')                      # replace in subclasses
    self.quit()

if name == 'main':
HelloButton(text='Hello subclass world').mainloop()

13、self.config fg,bg,font,relief

14、frame重载
from tkinter import *

class Hello(Frame): # an extended Frame
def init(self, parent=None):
Frame.init(self, parent) # do superclass init
self.pack()
self.data = 42
self.make_widgets() # attach widgets to self

def make_widgets(self):
    widget = Button(self, text='Hello frame world!', command=self.message)
    widget.pack(side=LEFT)

def message(self):
    self.data += 1
    print('Hello frame world %s!' % self.data)

if name == 'main': Hello().mainloop()
15、Hello.widget() 父类和子类的方法都执行
