正确打印条目小部件输入 Python3.5
Properly print entry widget input Python3.5
好的,这是我的问题:
下面的代码,当被按钮调用时,打印 NOTHING。为什么? (是的,我当然是在输入框中输入内容。)
options = Tk()
options.geometry("218x156")
options.iconbitmap('original.ico')
options.title("Options")
Label(options, text = "GitHub Username:").pack()
userName = StringVar()
Entry(options, width = "30", textvariable = userName).pack()
Label(options, text = "GitHub Email:").pack()
userEmail = StringVar()
Entry(options, width = "30", textvariable = userEmail).pack()
Label(options, text = "GitHub Password:").pack()
userPassword = StringVar()
Entry(options, show = "•", width = "30", textvariable = userPassword).pack()
def optionSave():
print(userName.get())
print(userEmail.get())
print(userPassword.get())
options.destroy()
有效,并且
def fileOptions():
options = Tk()
options.geometry("218x156")
options.iconbitmap('original.ico')
options.title("Options")
Label(options, text = "GitHub Username:").pack()
userName = StringVar()
Entry(options, width = "30", textvariable = userName).pack()
Label(options, text = "GitHub Email:").pack()
userEmail = StringVar()
Entry(options, width = "30", textvariable = userEmail).pack()
Label(options, text = "GitHub Password:").pack()
userPassword = StringVar()
Entry(options, show = "•", width = "30", textvariable = userPassword).pack()
def optionSave():
print(userName.get())
print(userEmail.get())
print(userPassword.get())
options.destroy()
没有
请注意:唯一明显的区别是
上的代码
底部没有包起来def fileOptions():
输出为空白。正如它在控制台中打印 zilch 一样。这是因为它在单独的 Window 中吗?如果是这样,我该如何解决?
现在...回答我自己的问题!
而不是:
userName = StringVar()
Entry(options, width = "30", textvariable = userName).pack()
像这样定义条目小部件:
userName = StringVar()
userName = Entry(options, width = "30")
userName.pack()
将 .pack()
向下移动到它自己的行,如 userName.pack()
然后像这样打印它:
print(userName.get())
您想要的所有条目小部件。
