Python3 graphical Interface Simple case (Tkinter)

1. For the use of dialog boxes in Python3:

Note that there are a lot of changes in python3 relative to Python2, some of which are changed by the name of the Tkinter, which changes to Tkinter, and the dialog box can be used by importing python2 in Tkmessagebox, for example:
Tkmessagebox.showifo ("MessageBox", "This is a MessageBox")

This module has become MessageBox in Python3, and we only need to import Tkinter.messagebox to use (tk = TK ()):

Tk.messagebox.showinfo ("MessageBox", "This is a MessageBox")

Refer to the case:

From tkinter Import * Import Tkinter.messagebox class Mainwindow:def ButtonListener1 (self,event): TKINTER.M Essagebox.showinfo ("MessageBox", "This is Button 1 dialog") def buttonListener2 (self,event): Tkinter.messagebox . Showinfo ("MessageBox", "This is button 2 Dialog") def buttonListener3 (self,event): Tkinter.messagebox.showinfo (' MessageBox ', ' This is button 3 dialog ') def buttonListener4 (self,event): Tkinter.messagebox.showinfo ("message Box "," This is button 4 Dialog ") def __init__ (self): Self.frame = Tk () self.button1 = button (Self.frame,text = "Button1", Width = 10,height = 5) Self.button2 = button (Self.frame,text = "Button2", Width = 10,h eight = 5) Self.button3 = button (Self.frame,text = "Button3", width = 10,height = 5) Self.button4 = button (
        Self.frame,text = "Button4", width = 10,height = 5) self.button1.grid (row = 0,column = 0,PADX = 5,pady = 5) Self.button2.grid (row= 0,column = 1,PADX = 5,pady = 5) self.button3.grid (row = 1,column = 0,PADX = 5,pady = 5) Self.button4.gri
        D (row = 1,column = 1,PADX = 5,pady = 5) self.button1.bind ("<ButtonRelease-1>", Self.buttonlistener1) Self.button2.bind ("<ButtonRelease-1>", Self.buttonlistener2) self.button3.bind ("<ButtonRelease-1>", SELF.BUTTONLISTENER3) Self.button4.bind ("<ButtonRelease-1>", Self.buttonlistener4) Self.frame.mainlo OP () window = MainWindow ()

The results of a graphical interface (which is notable for self) are shown in the way that the class is defined to run as follows:

Two examples of graphical interfaces written in Python:

From tkinter Import * class Mainwindow:def __init__ (self): Self.frame = Tk () Self.label_name = Labe L (self.frame,text = "Name:") self.label_age = label (Self.frame,text = "Age:") Self.label_sex = label (self. Frame,text = "Sex:") self.text_name = text (self.frame,height = "1", width =) Self.text_age = text (self. Frame,height = "1", width = Self.text_sex = text (self.frame,height = "1", width =) self.label_name.g

        RID (row = 0,column = 0) self.label_age.grid (row = 1,column = 0) self.label_sex.grid (row = 2,column = 0) SELF.BUTTON_OK = button (Self.frame,text = "OK", Width = ten) Self.button_cancel = button (Self.frame,text = "C
        Ancel ", width = ten" self.text_name.grid (row = 0,column = 1) self.text_age.grid (row = 1,column = 1) Self.text_sex.grid (row = 2,column = 1) self.button_ok.grid (row = 3,column = 0) self.button_cance L.grid (row = 3,column =1) self.frame.mainloop () frame = MainWindow () 

Run Result:
