Visual TKinter - Demo
自制的简单计算器
如果这个界面直接在python的节面编辑的话，总感觉不太方便，但是在VB中就非常方便了，控件可以随意拖放，按钮大小、背景颜色，只要VB中可调的，都能设置。
界面设置完以后直接点“生成代码”：#!/usr/bin/env python
#-*- coding:utf-8 -*-
import os, sys
try:
from tkinter import *
except ImportError: #Python 2.x
PythonVersion = 2
from Tkinter import *
from tkFont import Font
from ttk import *
#Usage:showinfo/warning/error,askquestion/okcancel/yesno/retrycancel
from tkMessageBox import *
#Usage:f=tkFileDialog.askopenfilename(initialdir='E:/Python')
#import tkFileDialog
#import tkSimpleDialog
else: #Python 3.x
PythonVersion = 3
from tkinter.font import Font
from tkinter.ttk import *
from tkinter.messagebox import *
#import tkinter.filedialog as tkFileDialog
#import tkinter.simpledialog as tkSimpleDialog #askstring()
class Application_ui(Frame):
#这个类仅实现界面生成功能，具体事件处理代码在子类Application中。
def __init__(self, master=None):
Frame.__init__(self, master)
self.master.title('Visual Tkinter - Demo')
self.master.geometry('287x193')
self.master.resizable(0,0)
self.createWidgets()
def createWidgets(self):
self.top = self.winfo_toplevel()
self.style = Style()
self.Text1Var = StringVar(value='')
self.Text1 = Entry(self.top, textvariable=self.Text1Var)
self.Text1.place(relx=0.474, rely=0.124, relwidth=0.394, relheight=0.42)
self.Command2 = Button(self.top, text=u'退 出', command=self.Command2_Cmd)
self.Command2.place(relx=0.557, rely=0.622, relwidth=0.31, relheight=0.212)
self.Command1 = Button(self.top, text=u'计 算', command=self.Command1_Cmd)
self.Command1.place(relx=0.111, rely=0.622, relwidth=0.338, relheight=0.212)
self.style.configure('Label1.TLabel',anchor='center')
self.Label1 = Label(self.top, text=u'计算结果', style='Label1.TLabel')
self.Label1.place(relx=0.111, rely=0.124, relwidth=0.254, relheight=0.13)
self.Text2Var = StringVar(value='')
self.Text2 = Entry(self.top, textvariable=self.Text2Var)
self.Text2.place(relx=0.084, rely=0.415, relwidth=0.31, relheight=0.093)
class Application(Application_ui):
#这个类实现具体的事件处理回调函数。界面生成代码在Application_ui中。
def __init__(self, master=None):
Application_ui.__init__(self, master)
def Command2_Cmd(self, event=None):
#TODO, Please finish the function here!
pass
def Command1_Cmd(self, event=None):
#TODO, Please finish the function here!
pass
if __name__ == "__main__":
top = Tk()
Application(top).mainloop()
try: top.destroy()
except: pass
剩下我们要做的就是完善2个Command的命令（生成的代码中已经帮你标示出来了，非常人性化！）
我们修改代码后，直接保存即可。#!/usr/bin/env python
#-*- coding:utf-8 -*-

from tkinter.font import Font

def createWidgets(self):
self.top = self.winfo_toplevel()

self.Text1Var = StringVar(value='')
self.Text1 = Entry(self.top, textvariable=self.Text1Var)
self.Text1.place(relx=0.474, rely=0.124, relwidth=0.394, relheight=0.42)
gComps['Text1Var'] = self.Text1Var
self.Command2 = Button(self.top, text=u'退 出', command=self.Command2_Cmd)
self.Command2.place(relx=0.557, rely=0.622, relwidth=0.31, relheight=0.212)
self.Command1 = Button(self.top, text=u'计 算', command=self.Command1_Cmd)
self.Command1.place(relx=0.111, rely=0.622, relwidth=0.338, relheight=0.212)
self.style.configure('Label1.TLabel',anchor='center')
self.Label1 = Label(self.top, text=u'计算结果', style='Label1.TLabel')
self.Label1.place(relx=0.111, rely=0.124, relwidth=0.254, relheight=0.13)
self.Text2Var = StringVar(value='')
self.Text2 = Entry(self.top, textvariable=self.Text2Var)
self.Text2.place(relx=0.084, rely=0.415, relwidth=0.31, relheight=0.093)
gComps['Text2Var'] = self.Text2Var
class Application(Application_ui):
#这个类实现具体的事件处理回调函数。界面生成代码在Application_ui中。
def __init__(self, master=None):
Application_ui.__init__(self, master)
def Command2_Cmd(self, event=None):
try: top.destroy()
except: pass
sys.exit()
def Command1_Cmd(self, event=None):
txt = gComps['Text1Var'].get()
result = eval(txt)
gComps['Text2Var'].set(str(result).decode('utf-8'))
gComps = {}
if __name__ == "__main__":
top = Tk()
Application(top).mainloop()
try: top.destroy()
except: pass
轻松加愉快，整个过程5分钟搞定！ |
