因此，我需要找到每个匹配的单词，点击按钮在文本框中添加滚动条。此函数只查找第一个匹配单词。如何将更新后的索引提供给绑定到按钮的函数？
def find(idx='1.0'):
text.tag_remove('found', idx, END)
s = edit.get()
if s:
idx = text.search(s, idx, nocase=1,
stopindex=END)
if not idx:
return None
foundidx = '%s+%dc' % (idx, len(s))
text.tag_add('found', idx, foundidx)
text.see(foundidx)
text.tag_config('found', foreground='red')
edit.focus_set()
return foundidx
要实现这一点，您需要一个Text小部件和一个通过小部件显示示例文本的根。我用这个做到了：
import tkinter as tk
root = tk.Tk()
text = tk.Text(root)
text.pack()
text.insert('1.0','''

在这之后，我按照指示的链接出了评论。并通过保存仓位和索引来扩展它。
countVar = tk.StringVar()
idxVar = tk.StringVar()
posis = []
def search():
try:
if idxVar.get():
new_idx = float(idxVar.get()+countVar.get())
pos = text.search('sed', new_idx, 'end', count=countVar)
text.tag_add('search', pos, '%s + %sc' % (pos, countVar.get()))
text.tag_configure('search', background='green')
idxVar.set(pos)
posis.append(pos)
else:
pos = text.search('sed', '1.0', 'end', count=countVar)
text.tag_add('search', pos, '%s + %sc' % (pos, countVar.get()))
text.tag_configure('search', background='green')
idxVar.set(pos)
posis.append(pos)
except:
idxVar.set('1.0')
button = tk.Button(root,text='search',command=search)
button.pack()
至少我使用了Text.see方法来跳转到我的职位列表中的点：
show = tk.IntVar()
show.set(0)
def see():
if show.get() <= len(posis)-1:
pos = show.get()
text.see(posis[show.get()])
show.set(pos+1)
else:
show.set(0)
button2= tk.Button(root,text='see', command=see)
button2.pack()
root.mainloop()
我知道这段代码可以改进很多，但它应该显示出原理，我过去对它的编码是不言自明的。但如果有悬而未决的问题，请告诉我，我会改进这个答案。
