附加带有 google 搜索结果的 tkinter 文本小部件

Question

早上好，现在我正在努力使用一个小程序，它可以让你在 tkinter GUI 中搜索 google。按下按钮后，它应该会显示该结果的所有链接（对我而言，我将其限制为 10 个）。我的程序可以运行，但它不会附加文本框，而只会显示查询的最后结果。我代码的重要部分从 def clicked() 开始。

import tkinter
import PIL.Image, PIL.ImageTk
import cv2
from googlesearch import search

window = tkinter.Tk()

window.title("Google Search")
window.geometry('1000x1000')

img = "pics1/dt.jpg"
img2 = "pics2/donald.jpg"
cv_img = cv2.imread(img)
cv_img2 = cv2.imread(img2)
height, width, no_channels = cv_img.shape
height, width, no_channels = cv_img2.shape
canvas = tkinter.Canvas(window, width = 300, height = 300)
canvas.grid(row=0, column=2)
photo = PIL.ImageTk.PhotoImage(image = PIL.Image.fromarray(cv_img))
canvas.create_image(0, 0, image=photo, anchor=tkinter.NW)

######


txt = tkinter.Entry(window,width=10)
txt.grid(column=0, row=1)
lbl = tkinter.Label(window, text="Who do you want to search?")
lbl.grid(column=0, row=0)


canvas2 = tkinter.Canvas(window, width = 300, height = 300)
canvas2.grid(row=0, column=1)
photo2 = PIL.ImageTk.PhotoImage(image = PIL.Image.fromarray(cv_img2))
canvas2.create_image(0, 0, image=photo2, anchor=tkinter.NW)

query = ""

def clicked():
    res = "Thanks"
    global query
    query = txt.get()
    lbl.configure(text=res)

    for j in search(query, tld='com', lang='en', num=10, start=0, stop=10, pause=2):
        final = tkinter.Text(window, text=j)

btn = tkinter.Button(window, text="Search", command=clicked)
btn.grid(column=0, row=3)





window.mainloop()

谢谢

解决方案是从函数中删除文本小部件的创建，而是在脚本的主要部分创建它。然后，调用 insert 方法插入文本小部件。

window = tkinter.Tk()
...
text = tkinter.Text(window)
# this is just guessing where you want it; put
# it wherever you want. 
text.grid(row=2, column=0, columnspan=3)
...

def clicked():
    ...
    for j in search(query, tld='com', lang='en', num=10, start=0, stop=10, pause=2):
        text.insert("end", j)

如果结果未以换行符结尾，您将需要添加一个。例如：

text.insert("end", j+"\n")
