Python 3 tkinter insert file contents into a text box - python-3.x

Question

Okay so I have done about 10 days of searching and I caved in so I'm turning to the community for help.
I am using python 3.6 and tkinter as a user interface.
The basic's of what I'm trying to accomplish is that I have a file that I open and search for a word within the file and insert all the lines that word falls on.
My issue is that its only inserting the first line it finds and I need it to insert all the lines it finds. Sorry for wet coding I'll dry it up once I have functionality later
here's a sample of my code (it's not the full thing but it should give you more than enough info about what I'm trying to accomplish):
import tkinter as tk
from tkinter import ttk
# i added all my imports that this class use's in case you guys think they could pose a problem but they shouldn't be a issue
class EXAMPLEapp(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
tk.Tk.iconbitmap(self, default = "dlm64.ico")
tk.Tk.wm_title(self, "Example.")
self.FILE_MENU_BAR()
self.minsize(width = 360, height = 200)
container = tk.Frame(self)
container.grid(row=0,column=0, sticky="nsew")
container.grid_rowconfigure(0, weight = 1)
container.grid_columnconfigure(0, weight = 1)
self.frames = {}
for FRAME in (SearchPage):
frame = FRAME(container, self)
self.frames[FRAME] = frame
frame.grid(row = 0, column = 0, sticky = "nsew")
self.show_frame(SearchPage)
def FILE_MENU_BAR(self):
#File
self.menubar = tk.Menu()
self.configure(menu = self.menubar)
File_Menu = tk.Menu(self.menubar, tearoff = False)
self.menubar.add_cascade(label = "File", menu = File_Menu)
File_Menu.add_command(label = "EXIT" , command = self.File_EXIT)
# Edit Menu
Edit_Menu = tk.Menu(self.menubar, tearoff = False)
self.menubar.add_cascade(label = "Edit", menu = Edit_Menu)

EDIT:
I have made several changes to your code.
There were way too many emblems with the way you had it set up.
As I am not 100% sure how what you are trying to accomplish I have made progress with your code.
Below is the edited version of your code.
I also created a text file on my end to test with and it seams to have worked so let me know if this is getting close to what you are attempting to do.
A few notes:
1st I moved everything into one class. The way you had it set up was just not going to work without some major changes.
2nd I needed to add self. to many of your variables because they are variables that we need to interact with in the class.
3rd I changed they way you get the data from the entry box. The way you were doing it was just not working so I simplified it by adding .get() function to the entry variable.
4th but probably should have been the 1st thing I mentions. The way you had your main Tk() window starting was odd. I changed how root was created and how we pass it into the class. This seams to make more sense to me.
This is much better to use IMO.
Let me know what parts you still need explanation on and I will make updates to my answer as needed.
Update:
change the while open statement a bit. You do not need to recreate the text box and reconfigure it ever for loop this is not good and will prevent you from seeing multiple items. Also I do not believe you can have a multi line label thought I have never tried. Lets change this to a text box this should do what we need.
