How to scrolldown a textbox using scrollbar widget tkinter

Application: Building a notes application (as an intro to GUI development in Python) which includes feature of a scrollbar to scroll through a textbox
Problem: I can't actually seem to scroll down through the textbox. I don't seem to get the grayed rectangle which lets me control the scrollbar and scroll up/down through the textbox

I would also be very grateful if one could explain the concept of scrollbar.set and like yview and why they are both needed for the scrollbar to work. Tutorials and videos don't seem to explain the concept, but just implement it

also, why does the border in the f_lbl, simplistic clock not fully extended through out all 4 column since i put columnspan = 4 , and weight = 1 , should't it expand fully through all 4 columns?

Tkinter grid method

I'm using Tkinter to create a GUI for my computer science coursework based on steganography. I'm using the .grid() function on the widgets in my window to lay them out, however I can't get this particular part to look how I want it to.
Here's what my GUI currently looks like: http://imgur.com/LNEZtEL
(or just the part with the error).
I want the remaining characters label to sit directly underneath the text entry box, but for some reason row 4 starts a large way down underneath the box. If I label the GUI with columns and rows anchored north west it looks like this: http://imgur.com/a/V7dTW.
If I shrink the image box on the left, it looks how I want, however I don't want the image this small: http://imgur.com/a/0Dudu.
The image box has a rowspan of 2, so what is causing the 4th row to start so low down from the text entry box? Here's roughly what I want the GUI to look like: http://imgur.com/a/ck04A.
Full code:
imageButton = Button(root, text="Add Image", command = add_image)
imageButton.grid(row = 2, columnspan = 2, sticky = W, padx = 30, pady = 20)
steg_widgets.append(imageButton)
image = Image.open("square.jpg")
image = image.resize((250,250))
photo = ImageTk.PhotoImage(image)
pictureLabel = Label(root, image = photo)
pictureLabel.image = photo
pictureLabel.grid(column = 0, row = 3, columnspan = 2, rowspan = 2, padx = 20, pady = (0, 20), sticky = NW)
steg_widgets.append(pictureLabel)
nameLabel = Label(root, text = "Brandon Edwards - OCR Computer Science Coursework 2016/2017")
nameLabel.grid(row = 0, column = 2, columnspan = 2, padx = (0, 20), pady = 10)
steg_widgets.append(nameLabel)
inputTextLabel = Label(root, text = "Enter text:")
inputTextLabel.grid(row = 2, column = 2, sticky = W)
steg_widgets.append(inputTextLabel)
startButton = Button(root, text="Go!", command = start_stega)
startButton.grid(row = 2, column = 2, sticky = E)
steg_widgets.append(startButton)
inputTextBox = Text(root, height = 10, width = 30)
inputTextBox.grid(row = 3, column = 2, sticky = NW)
steg_widgets.append(inputTextBox)
maxCharLabel = Label(root, text = "Remaining characters:")
maxCharLabel.grid(row = 4, column = 2, sticky = NW)
steg_widgets.append(maxCharLabel)
saveButton = Button(root, text="Save Image", command = save_image)
saveButton.grid(row = 2, column = 3, sticky = W)
steg_widgets.append(saveButton)

I recommend breaking your UI down into logical sections, and laying out each section separately.
For example, you clearly have two distinct sections: the image and button on the left, and the other widgets on the right. Start by creating containers for those two groups:
import Tkinter as tk
...
left_side = tk.Frame(root)
right_side = tk.Frame(root)
Since they are side-by-side, pack is the simplest way to lay them out:
left_side.pack(side="left", fill="y", expand=False)
right_side.pack(side="right", fill="both", expand=True)
Next, you can focus on just one side. You can use pack or grid. This uses grid for illustrative purposes:
image = tk.Canvas(left_side, ...)
button = tk.Button(left_side, ...)
left_side.grid_rowconfigure(0, weight=1)
left_side.grid_columnconfigure(0, weight=1)
image.grid(row=0, column=0, sticky="nw")
button.grid(row=1, column=0, sticky="n")
Finally, work on the right side. Since widgets are stacked top-to-bottom, pack is the natural choice:
l1 = tk.Label(right_side, text="Enter text:")
l2 = tk.Label(right_side, text="Remaining characters")
text = tk.Text(right_side)
l1.pack(side="top", fill="x")
text.pack(side="top", fill="both", expand=True)
l2.pack(side="top", fill="x")

Executable using tkinter and multiprocessing creates multiple windows

I have built a gui for a script using tkinter.
I have tried building an executable with both cx_freeze and pyinstaller.
I make extensive use of scipy, numpy, statsmodels and matplotlib
Whenever I click the "Run" button, it spawns another window and the window beneath it stops responding. This can occur seemingly indefinitely.
I do use multiprocessing in my application, but I fixed the multiple windows issue in the python script version
How do I fix the multiple windows issue in my standalone program?
If there is not a reasonable fix, is there another way to package the program for use? Maybe a custom Python distribution?

Two processes or more can't share a single root window. Every process that creates a widget will get its own window.

I managed to fix this with some experimentation.
It no longer launches multiple windows after I made the business logic launch within the same process.

Tkinter - Text widget shrinks when Scrollbar is added

I'm working on the GUI for a simple quiz app using Tkinter in Python 2.7.
Thus far, I have begun to set up my frame. I've put a scrollbar inside of a Text widget named results_txtbx to scroll up and down a list noting the player's performance on each question. I've been using grid since it's easier for me to manage.
from Tkinter import *
class Q_and_A:
def __init__(self, master):
frame = Frame(master)
Label(master).grid(row = 4)
results_txtbx = Text(master)
results_scrbr = Scrollbar(results_txtbx)
results_scrbr.grid(sticky = NS + E)
results_txtbx.config(width = 20, height = 4, wrap = NONE, yscrollcommand = results_scrbr.set)
results_txtbx.grid(row = 3, column = 1, padx = 12, sticky = W)
root = Tk()
root.wm_title("Question and Answer")
root.resizable(0, 0)
app = Q_and_A(root)
root.mainloop()
What happens is that when it runs, results_txtbx resizes to fit the scrollbar. Is there any way to make it keep its original size using grid?

You don't want to use a text widget as the master for a scrollbar. Like any other widget, if you pack or grid the scrollbar in the text widget, the text widget will shrink or expand to fit the scrollbar. That is the crux of your problem.
Instead, create a separate frame (which you're already doing), and use that frame as the parent for both the text widget and the scrollbars. If you want the appearance that the scrollbars are inside, set the borderwidth of the text widget to zero, and then give the containing frame a small border.
As a final usability hint, I recommend not making the window non-resizable. Your users probably know better what size of window they want than you do. Don't take that control away from your users.
Here's (roughly) how I would implement your code:
I would use import Tkinter as tk rather than from Tkinter import * since global imports are generally a bad idea.
I would make Q_and_A a subclass of tk.Frame so that it can be treated as a widget.
I would make the whole window resizable
I would separate widget creation from widget layout, so all my layout options are in one place. This makes it easier to write and maintain, IMO.
As mentioned in my answer, I would put the text and scrollbar widgets inside a frame
Here's the final result:
import Tkinter as tk
class Q_and_A(tk.Frame):
def __init__(self, master):
tk.Frame.__init__(self, master, borderwidth=1, relief="sunken")
self.label = tk.Label(self)
self.results_txtbx = tk.Text(self, width=20, height=4, wrap="none",
borderwidth=0, highlightthickness=0)
self.results_scrbr = tk.Scrollbar(self, orient="vertical",
command=self.results_txtbx.yview)
self.results_txtbx.configure(yscrollcommand=self.results_scrbr.set)
self.label.grid(row=1, columnspan=2)
self.results_scrbr.grid(row=0, column=1, sticky="ns")
self.results_txtbx.grid(row=0, column=0, sticky="nsew")
self.grid_rowconfigure(0, weight=1)
self.grid_columnconfigure(0, weight=1)
root = tk.Tk()
root.wm_title("Question And Answer")
app = Q_and_A(root)
app.pack(side="top", fill="both", expand=True)
root.mainloop()

Set results_scrbr.grid(row = 3, column = 2) next to results_txtbx.grid(row = 3,column = 1, padx = 4), sticky is not needed because window is not resizable, and i lowered the padx so scrollbar is closer to text.
Also to make the results_txtbx vertically scrollable, add results_scrbr.config(command=results_txtbx.yview)
Here is a working code...
from Tkinter import *
class Q_and_A:
def __init__(self, master):
frame = Frame(master)
Label(master).grid(row = 4)
results_txtbx = Text(master)
results_scrbr = Scrollbar(master)
results_scrbr.grid(row = 3, column = 2)
results_scrbr.config(command=results_txtbx.yview)
results_txtbx.config(width = 20, height = 4,
wrap = NONE, yscrollcommand = results_scrbr.set)
results_txtbx.grid(row = 3, column = 1, padx = 4)
root = Tk()
root.wm_title("Question and Answer")
root.resizable(0, 0)
app = Q_and_A(root)
root.mainloop()

My implemented solution:
I needed to add more widgets to the app, so I bound the Scrollbar and Text widgets to another label and put that in the proper column the code (trimmed for readability) is below:
import Tkinter as tk
class Q_and_A(tk.Frame):
def __init__(self, master):
tk.Frame.__init__(self, master)
self.label = tk.Label(self)
#Set up menu strip
self.main_menu = tk.Menu(self)
self.file_menu = tk.Menu(self.main_menu, tearoff = 0)
self.file_menu.add_command(label = "Exit", command = self.quit)
self.main_menu.add_cascade(label = "File", menu = self.file_menu)
self.master.config(menu = self.main_menu)
#Set up labels
self.question_lbl = tk.Label(self, text = "Question #: ", padx = 12, pady = 6)
self.question_lbl.grid(row = 0, sticky = "w")
tk.Label(self, text = "Hint: ").grid(row = 1, sticky = "w", padx = 12, pady = 6)
tk.Label(self, text = "Answer: ").grid(row = 2, sticky = "w", padx = 12, pady = 6)
tk.Label(self, text = "Results: ").grid(row = 3, sticky = "nw", padx = 12, pady = 6)
tk.Label(self).grid(row = 4)
#Set up textboxes
self.question_txtbx = tk.Entry(self)
self.question_txtbx.config(width = 60)
self.question_txtbx.grid(row = 0, column = 1, padx = 12, columnspan = 3, sticky = "w")
self.help_txtbx = tk.Entry(self)
self.help_txtbx.config(width = 40)
self.help_txtbx.grid(row = 1, column = 1, columnspan = 2, padx = 12, sticky = "w")
self.answer_txtbx = tk.Entry(self)
self.answer_txtbx.config(width = 40)
self.answer_txtbx.grid(row = 2, column = 1, columnspan = 2, padx = 12, sticky = "w")
self.results_label = tk.Label(self)
self.results_txtbx = tk.Text(self.results_label, width = 10, height = 4, wrap = "none", borderwidth = 1, highlightthickness = 1)
self.results_scrbr = tk.Scrollbar(self.results_label, orient = "vertical", command = self.results_txtbx.yview)
self.results_txtbx.configure(yscrollcommand = self.results_scrbr.set)
self.label.grid(row = 1)
self.results_label.grid(row = 3, column = 1, padx = 11, sticky = "w")
self.results_scrbr.grid(row = 0, column = 1, sticky = "nse")
self.results_txtbx.grid(row = 0, column = 0, sticky = "w")
root = tk.Tk()
root.wm_title("Question and Answer")
#A note: The window is non-resizable due to project specifications.
root.resizable(0, 0)
app = Q_and_A(root)
app.pack(side = "top", fill = "both")
root.mainloop()
I'll keep storage in nested labels as a reference for myself for when I need to group things close together, unless there's some reason it should be avoided. Worked very well here. Thanks to Bryan for the advice.
