问题描述
我想使用python中的tkinter模块制作一个简单的家庭帐户程序。我想将okclick
函数绑定到button1
。我想我已经编码了适当的引用其他代码,但是当我执行此代码时,会出现一条消息,提示未定义函数okclick
。
有人知道这是怎么回事吗?
from tkinter import *
from tkinter import ttk
import colors as c
from tkcalendar import DateEntry
b=Tk()
class memo(Frame):
def __init__(self,master):
Frame.__init__(self,master)
self.master=master
self.master.title('Memo')
self.pack(fill=BOTH,expand=True)
frame1=Frame(self,width=500,height=50)
frame1.pack(expand=False)
label1=Label(frame1,text='Amount',width=10)
label1.pack(side=LEFT,padx=10,pady=10)
entry1=Entry(frame1,width=20)
entry1.pack(padx=10,fill=X,expand=True)
frame2=Frame(self,height=50)
frame2.pack(expand=False)
label2=Label(frame2,text='Cartegory',width=10)
label2.pack(side=LEFT,pady=10)
listBox1=ListBox(frame2,width=20)
listBox1.insert(END,"식료품비","잡화비","건강관리비","외식비")
listBox1.pack(side=LEFT,pady=10)
frame3=Frame(self,height=50)
frame3.pack(expand=False)
label3=Label(frame3,text='Date',width=10)
label3.pack(side=LEFT,pady=10)
dateentry = DateEntry(frame3)
dateentry.pack(padx=10,pady=10)
frame4=Frame(self,height=500)
frame4.pack(expand=False)
button1=Button(frame4,text='csv Export',command=self.okClick)
button1.pack(side=LEFT,pady=10)
def okClick(self):
name = self.entry1.get()
print(name)
a=memo(b)
a.mainloop()
解决方法
您的代码有些错误:
-
onClick需要传递给它的“自我”参数,您需要将“ command = onClick”更新为“ command = self.onClick”
-
您的entry1变量应设置为实例变量,方法是在其前面加上“ self”,以便可以从onClick方法访问它。变量范围在python OOP中有些不同。
