Python Tkinter basic control usage, pythontkinter

This article demonstrates the usage of the basic Python Tkinter control and shares it with you for your reference. The specific method is as follows:

#-*-Coding: UTF-8-*-from Tkinter import * def btn_click (): b2 ['text'] = 'clicked' evalue = e. get () print 'btn Click and Entry value is % s' % evalue def btn_click_bind (event): print 'enter b2' def show_toplevel (): top = Toplevel () top. title ('window 2 ') Label (top, text =' This is window 2 '). pack () root = Tk () root. title ('window 1 ') # display built-in images # x = Label (root, bitmap = 'warning') l = Label (root, fg = 'red ', bg = 'blue', text = 'hangwei', width = 34, height = 10) l. pack () # command specifies the function B = Button (root, text = 'clickme ', command = btn_click) called by the Button) B ['width'] = 10b ['height'] = 2b. pack () # bind the join Button and function b2 = Button (root, text = 'clickme2') b2.configure (width = 10, height = 2, state = 'Disabled ') b2.bind ("<Enter>", btn_click_bind) b2.pack () # pop-up Toplevel window b3 = Button (root, text = 'showtoplevel', command = show_toplevel) b3.pack () # input box e = Entry (root, text = 'input your name') e. pack () # Password box epwd = Entry (root, text = 'input your pwd', show = '*') epwd. pack () # menu def menu_click (): print 'I am Menu' xmenu = Menu (root) submenu = menu (xmenu, tearoff = 0) for item in ['java ', 'cpp ', 'C', 'php']: xmenu. add_command (label = item, command = menu_click) for item in ['think in Java', 'java web', 'android']: submenu. add_command (label = item, command = menu_click) xmenu. add_cascade (label = 'progame', menu = submenu) # pop-up menu def pop (event): submenu. post (event. x_root, event. y_root) # obtain the coordinate def get_clickpoint (event): print event. x, event. y # framefor x in ['red', 'blue', 'yellow']: Frame (height = 20, width = 20, bg = x ). pack () root ['menu '] = xmenuroot. bind ('<Button-3>', pop) root. bind ('<Button-1>', get_clickpoint) root. mainloop ()
