Change the content of a ttkbootstrap ScrolledFrame
问题
我如何替换ttkbootstrap ScrolledFrame的内容？
我已经使用以下代码创建了滚动帧：
for ndx, t in enumerate(sorted(tw, key=lambda x: x.created_at, reverse=True)):
print(t.created_at)
card = make_tweet_card(t, tweet_detail_scroller)
card.grid(pady=5, row=ndx, column=0, sticky="W")
基于按钮点击，我需要清空ScrolledFrame并用不同的内容替换它。
如何实现这一目标？

How do I replace the content of a ttkbootstrap ScrolledFrame?
I have built the scrolled frame with this snippet:
for ndx, t in enumerate(sorted(tw, key=lambda x: x.created_at, reverse=True)):
print(t.created_at)
card = make_tweet_card(t, tweet_detail_scroller)
card.grid(pady=5, row=ndx, column=0, sticky="W")
Based on a button click I need to empty the ScrolledFrame and replace the content with different content.
How can I achieve this?

我发现我需要一个单独的内容列表，然后才能对其进行遍历以进行销毁。
代码段现在如下：
if len(tweet_detail_scroller.children) > 0:
content = [cw for cw in tweet_detail_scroller.children.values()]
for cw in content:
cw.destroy()
for ndx, t in enumerate(sorted(tw, key=lambda x: x.created_at, reverse=True)):
print(t.created_at)
card = make_tweet_card(t, tweet_detail_scroller)
card.grid(pady=5, row=ndx, column=0, sticky="W")
其中 tw 包含新的推文列表。

I found that I needed a separate list of the content before I could iterate through it for destruction.
The snippet is now:
if len(tweet_detail_scroller.children) > 0:
content = [cw for cw in tweet_detail_scroller.children.values()]
for cw in content:
cw.destroy()
for ndx, t in enumerate(sorted(tw, key=lambda x: x.created_at, reverse=True)):
print(t.created_at)
card = make_tweet_card(t, tweet_detail_scroller)
card.grid(pady=5, row=ndx, column=0, sticky="W")
where tw contains the new list of tweets.
