python:Tkinter

Tkinter模块是Python的标准Tk GUI工具包接口。

0.示例

from Tkinter import *   # 显示一个窗口,有文字label和一个按钮
window = Tk()
label = Label(window,text = 'welcom')
button = Button(window,text = 'click')
label.pack()
button.pack()
window.mainloop()

 

from Tkinter import *  #点击按钮执行相应的程序
def procOK():
    print 'ok'
def procCancel():
    print 'cancel'
window = Tk()
btOK = Button(window,text = 'ok',fg = 'blue',command = procOK)
btCancel = Button(window,text = 'cancel',fg = 'blue',command = procCancel)
btOK.pack()
btCancel.pack()
window.mainloop()

 1.滑动条 Scale

   创建一个滑动条:

import Tkinter as tk
window = tk.Tk()
slider = tk.Scale(window,from_=0,to=100)
slider.pack()
window.mainloop()

   使用滑动条来调节画板的颜色实例:

from Tkinter import *

def sliderUpdate(source): #更新参数
    red = redSlider.get()
    green = greenSlider.get()
    blue = blueSlider.get()
    color = "#%02x%02x%02x" % (red,green,blue)
    canvas.config(bg = color)
    hexText.delete(0,END)
    hexText.insert(0,color)

window = Tk()
redSlider = Scale(window,from_=0,to=255,command = sliderUpdate)
greenSlider = Scale(window,from_=0,to=255,command = sliderUpdate)
blueSlider = Scale(window,from_=0,to=255,command = sliderUpdate)

canvas = Canvas(window,width = 200,height = 200)
hexText = Entry(window) #创建输入框
#排列这些控件
redSlider.grid(row = 1,column = 1)
greenSlider.grid(row = 1,column = 2)
blueSlider.grid(row = 1,column = 3)
canvas.grid(row = 2,column = 1,columnspan = 3)
hexText.grid(row = 3,column = 2)
            
window.mainloop()
