用于在Tkinter中选择python中的不同排序的GUI

Question

我将此代码用于单选按钮：

  v= IntVar()

  self.button1 = Radiobutton( self, text = "Bubble Sort" ,variable=v,value=1)
  self.button1.grid( row = 1, column = 0, sticky = W+E+N+S )


  self.button2 = Radiobutton( self, text = "Quick Sort",variable=v,value=2)
  self.button2.grid( row = 1, column = 1, sticky = W+E+N+S )


  self.button3 = Radiobutton( self, text = "Shell Sort", variable=v,value=3)
  self.button3.grid( row = 1, column = 2, sticky = W+E+N+S )

如需更多参考，完整代码如上所示，屏幕截图如下：

如何在选择排序后点击按钮对这些数字进行排序？我是否首先必须从三个给定的排序中选择，然后单击按钮排序以对数字进行排序？

以下是其余部分：

from Tkinter import *
import random
class Sorting( Frame ):
  def __init__( self ):
   Frame.__init__( self )
   self.master.title( "Sorting" )

   self.master.rowconfigure( 5, weight = 1 )
   self.master.columnconfigure( 5, weight = 1 )
   self.grid( sticky = W+E+N+S )
   #label for sort intro

   self.label1 = Label( self, text = "Select Sort", width = 25 ,height=2)
   self.label1.grid( row = 0, column = 1, sticky = N )



   #Radio buttons for sorts
   v= IntVar()

   self.button1 = Radiobutton( self, text = "Bubble Sort" ,variable=v,value=1)
   self.button1.grid( row = 1, column = 0, sticky = W+E+N+S )


   self.button2 = Radiobutton( self, text = "Quick Sort",variable=v,value=2)
   self.button2.grid( row = 1, column = 1, sticky = W+E+N+S )


   self.button3 = Radiobutton( self, text = "Shell Sort", variable=v,value=3)
   self.button3.grid( row = 1, column = 2, sticky = W+E+N+S )

 #function to do soting
   #def sort():

 #label to store value
   def gen():
    self.nums = []
    for x in range(0, 10):
       self.nums.append(random.randint(0, 100))
  # . . . . . . . . . .  .    <- maybe here call sorting method on self.nums


       num = ''.join('%4i' % num for num in self.nums)
       self.label2 = Label( self, text=num, width=2, height=2)
       self.label2.grid(row=3, columnspan=10, sticky=W+E+N+S)

         #self.label2.pack(fill="both")

     #Button for sorting
   self.button5=Button(self,text='start sorting')
   self.button5.grid( row = 4,column=1, sticky = W+E+N+S )

   #button to generate number
   self.button4 = Button( self,text='Generate no.',command=gen )
   self.button4.grid( row = 2,column=1, sticky = W+E+N+S )
   self.rowconfigure( 1, weight = 1 )
   self.columnconfigure( 1, weight = 1 )
def main():
  Sorting().mainloop()   

if __name__ == "__main__":
  main()

您必须为start sorting按钮实施回调方法：

  def sortit(self):
        function = self.function[self.v.get()]
        result = function()
        num = ''.join('%4i' % num for num in result)
        self.label3 = Label(self, text=num, width=2, height=2)
        self.label3.grid(row=5, columnspan=10, sticky=W+E+N+S )

在self.v.get()按下按钮。 此整数值用作存储排序方法名称的字典的键：

 self.function = {0:self.bubble, 1:self.quick, 2:self.shell}

然后result = function()为您提供调用相应排序方法的结果。您还要定义这些方法：

    def bubble(self):
        print('bubble to be implemented')
        return sorted(self.nums)

    def shell(self):
        print('shell to be implemented')
        return sorted(self.nums)

    def quick(self):
        print('quick to be implemented')
        return sorted(self.nums)

这是完整的代码：

import random
from tkinter import *

class Sorting(Frame):
    def __init__(self):
        Frame.__init__(self)
        self.function = {0:self.bubble, 1:self.quick, 2:self.shell}
        self.master.title("Sorting")
        self.master.rowconfigure(5, weight=1)
        self.master.columnconfigure(5, weight=1)
        self.grid(sticky=W+E+N+S )

        #label for sort intro
        self.label1 = Label(self, text="Select Sort", width=25, height=2)
        self.label1.grid(row=0, column=1, sticky=N)

        #Radio buttons for sorts
        self.v = IntVar()
        for indx, button in enumerate(('Bubble', 'Quick', 'Shell')):
            name = "%s Sort" % button
            button = Radiobutton(self, text=name, variable=self.v, value=indx)
            button.grid(row=1, column=indx, sticky=W+E+N+S)
        button.deselect()

        #button to generate number
        self.button4 = Button(self,text='Generate no.',command=self.gen)
        self.button4.grid(row=2, column=1, sticky=W+E+N+S)
        self.rowconfigure(5, weight=1)
        self.columnconfigure(5, weight=1)

    def create_but2sort(self):
        self.button5 = Button(self, text='start sorting', command=self.sortit)
        self.button5.grid(row=4, column=1, sticky=W+E+N+S)
        self.rowconfigure(5, weight=1 )
        self.columnconfigure(5, weight=1)

    def gen(self):
        self.nums = [random.randint(0, 100) for x in range(10)]
        num = ''.join('%4i' % num for num in self.nums)
        self.label2 = Label(self, text=num, width=2, height=2)
        self.label2.grid(row =3, columnspan=10, sticky = W+E+N+S)
        self.create_but2sort()

    def sortit(self):
        function = self.function[self.v.get()]
        result = function()
        num = ''.join('%4i' % num for num in result)
        self.label3 = Label(self, text=num, width=2, height=2)
        self.label3.grid(row=5, columnspan=10, sticky=W+E+N+S )

    def bubble(self):
        print('bubble to be implemented')
        return sorted(self.nums)

    def shell(self):
        print('shell to be implemented')
        return sorted(self.nums)

    def quick(self):
        print('quick to be implemented')
        return sorted(self.nums)

def main():
    Sorting().mainloop()
