In tkinter, how can I save text entered into a text area into an already open text file?-CodePudding

My code currently functions as follows:

create directory --> change working directory to created directory --> option to generate .txt files into directory, viewable in a listbox --> select a .txt file from listbox and view contents in a text widget.

What I am struggling with is then finding a way to enter text and save / append to the currently open/viewed text file in the text widget.

code:

from tkinter import *
from os import mkdir, getcwd, path, listdir, chdir

def dir_gen():
    curr_dir = getcwd()
    print("curr dir", curr_dir)
    fin_dir = path.join(curr_dir, r'note_folder')
    print("fin dir", fin_dir)
    if not path.exists(fin_dir):
        makedirs(fin_dir)
        print("directory created")

dir_gen()

flist = listdir("note_folder")
print("flist", flist)

chdir("note_folder")


def main_gui():
    window = Tk()
    window. geometry("400x400")
    window.config(bg="#000000")

    def go_home():
        window.destroy()
        main_gui()
        print("refreshed window")


    lbox = Listbox(window)
    lbox.place(x=20, y=20)

    listdir()
    print("listdir", listdir())
    for l in listdir():
        lbox.insert(END, l)


    add_note_entry = Entry(window)
    add_note_entry.place(x=20, y=190)
    add_note_entry.config(width=20)

    add_line_entry = Entry(window)
    add_line_entry.place(x=200, y=300)
    add_line_entry.config(width=27)


    def add_note():
        title = add_note_entry.get()
        hdl = open(title   ".txt", "w")
        hdl.close(), go_home()

    def open_note(event):
        x = lbox.curselection()[0]
        print("x", x)
        file = lbox.get(x)
        print("file", file)
        with open(file, 'r ') as file:
            file = file.read()
        text_output.delete('1.0', END)
        text_output.insert(END, file)

    def save_note():
        pass


    add_note_button = Button(window, command=add_note)
    add_note_button.place(x=40, y=210)
    add_note_button.config(width=10, height=2, text=("ADD NOTE"))

    save_note_button = Button(window, command=save_note)
    save_note_button.place(x=240, y=345)
    save_note_button.config(width=10, height=2, text=("SAVE NOTE"))

    text_output = Text(window)
    text_output.place(x=200, y=20)
    text_output.config(height=15, width=20)

    lbox.bind("<<ListboxSelect>>", open_note)

    window.mainloop()

main_gui()

I have tried

  def save_note(event):
        line = add_line_entry.get()
        x = lbox.curselection()[0]
        file = lbox.get(x)
        file = str(filename)
        print("file2", file)
        with open(file, 'a') as file:
            file.write(line)
        open_note()

and

  def save_note():
        x = lbox.curselection()[0]
        file = lbox.get(x)
        hdl = open(file, 'r ')
        nt = text_output.get(1)
        for l in nt:
            hdl.write(l)
        hdl.close()

as the main ways to get this functioning, unable to adjust either to get them running.

CodePudding user response：

In the second function, tkinter does not expect the text widget get function to be indexed with an integer. Here I have recreated the second save function but edited the line nt = text_output.get(1) to nt = text_output.get('1.0', 'end'). This gets everything from the first to last character in a tkinter text widget.

    def save_note():
        x = lbox.curselection()[0]
        file = lbox.get(x)
        hdl = open(file, 'r ')
        nt = text_output.get('1.0', 'end')
        for l in nt:
            hdl.write(l)
        hdl.close()
