如何导入模块并将其绑定到tkinter wind中的按钮

Question

我无法在tkinter窗口中bind将Button转换为module（实际上它甚至没有显示窗口）

我import这个module但是它运行，我想在我点击一个按钮之后运行它，而不是在之前。你知道吗

我怎样才能做到这一点，任何帮助都将不胜感激。这是我的GUI和模块代码

from Tkinter import*
import Tkinter as Tk

from DatasetCreator1 import DatasetCreator
class Buttons:
    def __init__(self, master):
        frame = Frame(master)
        frame.pack()

        self.TrainButton = Button(frame, text="Begin Train", 
                                  command = DatasetCreator.insertOrUpdate) 
        self.TrainButton.pack(side = LEFT)

        self.quitButton = Button(frame, text = "Quit", command = frame.quit)
        self.quitButton.pack(side = LEFT)

root = Tk()
b = Buttons(root)
root.mainloop()

当我运行这个时，它直接运行DatasetCreator1，而不显示任何tkinter窗口。它要求输入：

 enter your id

我的DatasetCreator1是：

import cv2
import sqlite3
import numpy as np

cam = cv2.VideoCapture(0)
detector=cv2.CascadeClassifier('Classifiers/haarcascade_frontalface_default.xml');


class DatasetCreator():
    def insertOrUpdate(Id,Name):
        conn=sqlite3.connect("Facebase0.db")
        cmd="SELECT * FROM People WHERE Id =" +str(Id)
        cursor=conn.execute(cmd)
        isRecordExist=0
        for row in cursor:
            isRecordExist=1
        if(isRecordExist==1):
            cmd="UPDATE people SET Name=' "+str(Name)+" ' WHERE ID="+str(Id)
        else:
            cmd="INSERT INTO people(ID,Name) Values("+str(Id)+",' "+str(Name)+" ' )"
        conn.execute(cmd)
        conn.commit()
        conn.close()

    ID = raw_input("enter your id")
    name = raw_input("enter your name")
    insertOrUpdate(ID,name)
    sampleNum=0
    while(True):
        ret, img = cam.read()
        gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
        faces = detector.detectMultiScale(gray, 1.3, 5)
        for (x,y,w,h) in faces:
            cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)

            #incrementing sample number 
            sampleNum=sampleNum+1
            #saving the captured face in the dataset folder
            cv2.imwrite("dataSet/User."+ID +'.'+ str(sampleNum) + ".jpg", gray[y:y+h,x:x+w])

            cv2.imshow('frame',img)
        #wait for 100 miliseconds 
        if cv2.waitKey(100) & 0xFF == ord('q'):
            break
        # break if the sample number is morethan 20
        elif sampleNum>20:
            break
    cam.release()
    cv2.destroyAllWindows()

我的DatasetCreator1的一些有趣的特性是，它仍然运行input('enter your id')
即使我删除了函数调用

 ID = raw_input("enter your id") # function call
 name = raw_input("enter your name")
 insertOrUpdate(ID,name)
 sampleNum=0

或者我在函数定义中没有给出参数

class DatasetCreator():
    def insertOrUpdate(Id,Name): # function definition
        conn=sqlite3.connect("Facebase0.db")
        cmd="SELECT * FROM People WHERE Id =" +str(Id)
        cursor=conn.execute(cmd)
