python tkinter

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

5、button

import sys

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

16、tkinter组件类：

Label,Button,Frame,TK,Message,Entry,Checkbutton,Radiobutton,Scale,PhotoImage,BitmapImage,Menu,Menubutton,Scrollbar,Text,Canvas
