为什么点击提交按钮后不执行密码验证
import tkinterwin=tkinter.Tk()
win.title('密码验证')
win['width']=600;win['height']=100
def mClick():
txt=txt2.get()
if(txt=='abc'):
txt3.set('欢迎进入游戏')
labl =tkinter.Label(win,text="请输入用户名:",fg='#0000ff',font=('华文新魏','16')).place(x=1,y=1)
lab2 =tkinter.Label(win,text="请输入密码:",fg='#0000ff',font=('华文新魏','16')).place(x=1,y=30)
txt1 =tkinter.StringVar()
txt2 =tkinter.StringVar()
txt3 =tkinter.StringVar()
txt3.set("请输入用户名和密码")
entry1 =tkinter.Entry(win,textvariable=txt1,width=16,font=('宋体','16')).place(x=160,y=1)
entry2 =tkinter.Entry(win,textvariable=txt2,width=16,show='*',font=('宋体','16')).place(x=160,y=30)
button =tkinter.Button(win,text='提交',bg='green',command=mClick,font=('宋体','16')).place(x=500,y=9)
label3 =tkinter.Label(win,textvariable =txt3,relief = 'ridge',width =30,\
font = ('华文新魏','16')).place(x=70,y=60)
win.mainloop()
因为你获取错了，你要获取 Entry 组件里的文本
txt=txt2.get()
改成：
txt = entry2.get()
而且如果 使用 entry2.get() 不能直接把组件被布局管理器给先调整了 要把这里代码：
entry2 =tkinter.Entry(win,textvariable=txt2,width=16,show='*',font=('宋体','16')).place(x=160,y=30)
改成：
entry2 = tkinter.Entry(win, textvariable=txt2, width=16, show='*', font=('宋体', '16'))
entry2.place(x=160, y=30)
完整代码：
import tkinter
win = tkinter.Tk()
win.title('密码验证')
win['width'] = 600
win['height'] = 100
def mClick():
txt = entry2.get()
if (txt == 'abc'):
txt3.set('欢迎进入游戏')
labl = tkinter.Label(win, text="请输入用户名:", fg='#0000ff', font=('华文新魏', '16')).place(x=1, y=1)
lab2 = tkinter.Label(win, text="请输入密码:", fg='#0000ff', font=('华文新魏', '16')).place(x=1, y=30)
txt1 = tkinter.StringVar()
txt2 = tkinter.StringVar()
txt3 = tkinter.StringVar()
txt3.set("请输入用户名和密码")
entry1 = tkinter.Entry(win, textvariable=txt1, width=16, font=('宋体', '16')).place(x=160, y=1)
entry2 = tkinter.Entry(win, textvariable=txt2, width=16, show='*', font=('宋体', '16'))
entry2.place(x=160, y=30)
button = tkinter.Button(win, text='提交', bg='green', command=mClick, font=('宋体', '16')).place(x=500, y=9)
label3 = tkinter.Label(win, textvariable=txt3, relief='ridge', width=30, \
font=('华文新魏', '16')).place(x=70, y=60)
win.mainloop()

怎么让登录验证成功后进入下面这个窗体界面
win.title("画图精灵！")
win.geometry('250x120+50+10')
label = tkinter.Label(win, \
text='欢迎来到我的世界！', \
font='宋体', \
fg='#0000ff'
)
label.pack()
btn1=tkinter. Button (win,text ='画布！',bg='green' )
btn1.pack(fill='y',side='left')
btn2=tkinter. Button (win,text ='国旗！',bg='red' )
btn2.pack(fill='y',side='right') 小诺爷 发表于 2020-6-11 13:39
