我一直试图为人们输入他们的名字做一个输入框,作为"注册的一部分"对于我正在做的迷你程序,但结果是输入框根本没有出现。
这段代码令我不安:
def win2(self):
# this is the child window
board = Toplevel()
board.title("Sign up")
board.focus_set()
board.grab_set()
userVar = StringVar()
userVar.set('Username')
square1Label = Label(board,textvariable=userVar)
square1Label.grid(row=0, column=7)
userEnt=Entry(self)
userEnt.grid(row=1, column=7)
s2Var = StringVar()
s2Var.set('First Name')
square2Label = Label(board,textvariable=s2Var)
square2Label.grid(row=1, column=7)
leaveButton = Button(board, text="Quit", command=board.destroy)
leaveButton.grid(row=1, column=1, sticky='nw')
board.wait_window(board)
这里是完整的编码,减去了Tkinter和主循环的导入:
class Application(Frame):
"""GUI Application for making Baakibook"""
def __init__(self, parent):
"""Initialize the frame"""
Frame.__init__(self, parent, bg="light blue")
self.win1()
# different windows
def win1(self):
# this is the main/root window
signupButton = Button(root, text="Sign up", command=self.win2)
signupButton.grid(row=9, column=7)
loginButton = Button(root, text="Log in", command=self.win3)
loginButton.grid(row=10, column=7)
leaveButton = Button(root, text="Quit", command=root.destroy)
leaveButton.grid(row=1, column=1, sticky='nw')
b1Var = StringVar()
b2Var = StringVar()
b1Var.set('b1')
b2Var.set('b2')
box1Label = Label(root,textvariable=b1Var,width=12)
box1Label.grid(row=3, column=2)
box2Label = Label(root,textvariable=b2Var,width=12)
box2Label.grid(row=3, column=3)
root.mainloop()
def win2(self):
# this is the child window
board = Toplevel()
board.title("Sign up")
board.focus_set()
board.grab_set()
userVar = StringVar()
userVar.set('Username')
square1Label = Label(board,textvariable=userVar)
square1Label.grid(row=0, column=7)
userEnt=Entry(self)
userEnt.grid(row=1, column=7)
s2Var = StringVar()
s2Var.set('First Name')
square2Label = Label(board,textvariable=s2Var)
square2Label.grid(row=1, column=7)
leaveButton = Button(board, text="Quit", command=board.destroy)
leaveButton.grid(row=1, column=1, sticky='nw')
board.wait_window(board)
def win3(self):
# this is the child window
board = Toplevel()
board.title("Login User")
board.focus_set()
board.grab_set()
s1Var = StringVar()
s2Var = StringVar()
s1Var.set("s1")
s2Var.set("s2")
square1Label = Label(board,textvariable=s1Var)
square1Label.grid(row=0, column=7)
square2Label = Label(board,textvariable=s2Var)
square2Label.grid(row=0, column=6)
leaveButton = Button(board, text="Quit", command=board.destroy)
leaveButton.grid(row=1, column=1, sticky='nw')
board.wait_window(board)
答案 0 :(得分:1)
用于创建窗口小部件的第一个参数是您希望将其分配给的父窗口。所以,这一行:
userEnt=Entry(self)
userEnt.grid(row=1, column=7)
在您Entry
中创建的Frame
中制作__init__
小部件。如果您希望它出现在Toplevel
中,请像在该方法中创建的其他小部件一样创建它,即:
userEnt=Entry(board)
userEnt.grid(row=1, column=7)
此外,Toplevel
中的网格现在没有意义,并且您的几个小工具将叠加显示,直到您更改它为止。
