[英]Tkinter text highlight with delay doesn't work
Goal: push a button to show and change the background of elements from a list one by one with a delay of n
seconds until the entire text is highlighted. 目标:按下按钮以逐个显示和更改列表中元素的背景,延迟
n
秒,直到高亮显示整个文本。
I wrapped: 我包裹:
text2.insert(INSERT,sonsilabo,"silabo")
text2.pack()
time.sleep(2)
in a for-loop to do that for each element. 在for循环中为每个元素执行此操作。
But the program still wait for the entire cycle to finish and show the final result. 但是程序仍然等待整个周期完成并显示最终结果。
from Tkinter import *
import Tkinter
import time
root = Tk()
text2 = Text(root)
text2.tag_config("silabo",background="green")
teksto = ['Sa','lu','to','n',' ','mi',' ','no','mi','ĝa','s',' ','A','b','de','l']
def kolorigu():
text2.delete('1.0', END)
for sonsilabo in teksto:
text2.insert(INSERT,sonsilabo,"silabo")
text2.pack()
time.sleep(2)
text2.pack()
B = Button(root, text ="Kolorigu", command = kolorigu)
B.pack()
root.mainloop()
Any idea? 任何想法?
After you add some text, you need to update the textbox by calling text2.update_idletasks
: 添加一些文本之后,您需要通过调用
text2.update_idletasks
来更新文本框:
def kolorigu():
text2.delete('1.0', END)
for sonsilabo in teksto:
text2.insert(INSERT,sonsilabo,"silabo")
########################
text2.update_idletasks()
########################
time.sleep(2)
Also, I removed the text2.pack()
line inside kolorigu
because it is unnecessary. 另外,我除去
text2.pack()
内部线kolorigu
因为它是不必要的。
