Question

我在Ubuntu上用Python编写程序，从文件夹导入文件然后单击左键单击以突出显示文件名

我正在尝试将突出显示的文本存储或分配为变量？

是否有python函数允许我通过单击左键单击捕获当前突出显示的文本并将其存储为变量？

请您指导我如何完成这项任务？

import subprocess,os
from Tkinter import *


def text_click_callback(event):
    # an event to highlight a line when single click is done
    line_no = event.widget.index("@%s,%s linestart" % (event.x, event.y))
    #print(line_no)
    line_end = event.widget.index("%s lineend" % line_no)
    event.widget.tag_remove("highlight", 1.0, "end")
    event.widget.tag_add("highlight", line_no, line_end)
    event.widget.tag_configure("highlight", background="yellow")




def viewFile():
    tex.delete('1.0', END)

    for f in os.listdir(path):
        linkname="link-" + f
        tex.insert(END,f + "\n", linkname)
        tex.tag_configure(linkname, foreground="blue", underline=True)
        tex.tag_bind(linkname, "<Button-1>", text_click_callback )    # highlight a line



if __name__ == '__main__':

    root = Tk()
    step = LabelFrame(root,text="FILE MANAGER", font = "Arial 20 bold   italic")
    step.grid(row=1, columnspan=7, sticky='W',padx=100, pady=5, ipadx=130, ipady=25)

    Button(step,    text="ViewFile",        font = "Arial 8 bold    italic",    activebackground="turquoise",   width=30, height=5, command=viewFile).grid      (row= 6, column =3)
    Button(step,    text="Exit",            font = "Arial 8 bold    italic",    activebackground="turquoise",   width=20, height=5, command=root.quit).grid     (row= 6, column =5)

    tex = Text(master=root)                                      # TextBox For Displaying File Information
    scr=Scrollbar(root,orient =VERTICAL,command=tex.yview)
    scr.grid(row=8, column=2, rowspan=15, columnspan=1, sticky=NS)
    tex.grid(row=8, column=1, sticky=E)
    tex.config(yscrollcommand=scr.set,font=('Arial', 8, 'bold', 'italic'))

    global process
    path = os.path.expanduser("/tmp")                   # Define path To play, delete, or rename video

    root.mainloop()

您可以使用与突出显示相同的索引来获取文本：

the_text = event.widget.get(line_no, line_end)

在Ubuntu上将强调文本分配/存储为Tkinter Python中的变量
