Question

I am using Tkinter in a programming assignment and have the following problem. I want the user to enter the value in a textbox, and I want to add additional fields on the GUI based on the number entered in the textbox when he/she clicks the submit-button.

我试图将代码放在显示器(Text)的功能内,在提交书-布顿受到压力时,该功能被称作;然而,我在窗户装满时,就把我放在该功能内的与全球倡议有关的代码装上。

import tkinter

#When user clicks on button
def displayText():
    #DO CHANGE IN GUI

root = tkinter.Tk()
button = tkinter.Button(root, text="Submit", command=displayText())
button.pack()

root.mainloop()

Answer 1

问题属于这一法典范畴:

button = tkinter.Button(root, text="Submit", command=displayText())

<代码>command 选项参引<>>。相反,你正在做的是 电话<>-em>指挥(<>条形码>><>>>>,并将指挥结果交给这一选择。您需要删除<代码>(),以便实际指挥与这一选择联系起来,例如:

button = tkinter.Button(root, text="Submit", command=displayText)
