如何删除所有子元素? [英] How to delete all children elements?

问题描述

我正在使用 Python 的 tkinter 库编写基于 GUI 的程序.我面临一个问题:我需要删除所有子元素(不删除父元素，在我的例子中是colorsFrame).

I am writing a GUI-based program using Python's tkinter library. I am facing a problem: I need to delete all children elements (without deleting a parent element, which in my case is colorsFrame).

我的代码:

infoFrame = Frame(toolsFrame, height = 50, bd = 5, bg = 'white')
colorsFrame = Frame(toolsFrame)

# adding some elements

infoFrame.pack(side = 'top', fill = 'both')
colorsFrame.pack(side = 'top', fill = 'both')

# set the clear button
Button(buttonsFrame, text = "Clear area",
               command = self.clearArea).place(x = 280, y = 10, height = 30)

我如何实现这一目标?

推荐答案

您可以使用 winfo_children 获取特定小部件的所有子部件的列表，然后您可以对其进行迭代:

You can use winfo_children to get a list of all children of a particular widget, which you can then iterate over:

for child in infoFrame.winfo_children():
    child.destroy()
