New to Tkinter GUI building

[Adam]

Hey,

I'm pretty new to programming. Been trying to learn using Python.
The code I'm struggling with is for my GUI.

I'm am having trouble getting this to display the way I want with the
grid manager. Can anybody tell me what I am doing wrong? I hope you
can tell what look I'm trying to achieve from the code as its hard to
explain.

I think my main questions are:
1. How can I get the Window to be sized the way I want it?
2. How can I get the Scrollbars to fill the side of the text box
instead of being small? (like .pack(fill= tk.Y)

#file/path finder
#indentation value 4
import os,glob
import Tkinter as tk

# Class to create the Application and UI
class Theapp:
    def __init__(self):
        # Create GUI parts. Will allign later with grid
        self.top = tk.Tk()
        self.mainWindow = tk.Frame(self.top, width=700, height=400)
        self.labAll = tk.Label(self.mainWindow, text="All Files/
Folders:")
        self.labVi = tk.Label(self.mainWindow, text="Violating Files/
Folders:")

        #Create a sub-frame containing textbox and scrollbar for All
files scanned display
        self.allTxtf = tk.Frame(self.mainWindow, width=699,
height=164)
        self.scrlr1 = tk.Scrollbar(self.allTxtf)
        self.txtBoxall = tk.Text(self.allTxtf, wrap=tk.CHAR,
yscrollcommand=self.scrlr1.set)
        self.scrlr1.config(command = self.txtBoxall.yview)

        #Create another sub-frame containing textbox and scrollbar for
the Violating files display
        self.viTxtf = tk.Frame(self.mainWindow, width=699, height=164)
        self.scrlr2 = tk.Scrollbar(self.viTxtf)
        self. txtBoxvi = tk.Text(self.viTxtf, wrap=tk.CHAR,
yscrollcommand=self.scrlr2.set)
        self.scrlr2.config(command = self.txtBoxvi.yview)

        #Create another sub-frame to contain the controls
        self.ctrlFrame = tk.Frame(self.mainWindow, width=699,
height=72)
        self.labDir = tk.Label(self.ctrlFrame, text="Dir:")
        self.entDir = tk.Entry(self.ctrlFrame)
        self.labChar = tk.Label(self.ctrlFrame, text="Char. Limit:")
        self.entChar = tk.Entry(self.ctrlFrame)
        self.btFind = tk.Button(self.ctrlFrame, text="Scan", command =
self.fillboxes)
        self.btExit = tk.Button(self.ctrlFrame, text="Exit", command =
self.quitEvent)


        #Use tkinter's grid geometry manager to allign and display the
GUI
        self.mainWindow.grid()
        #Frist allign the 3 main frames
        self.labAll.grid(row=0)
        self.allTxtf.grid(row=1)
        self.labVi.grid(row=2)
        self.viTxtf.grid(row=3)
        self.ctrlFrame.grid(row=4)
        #Now allign the content of allTxtf
        self.txtBoxall.grid(row=0, column=0)
        self.scrlr1.grid(row=0, column=1)
        #Now allign the content for viTxtf
        self.txtBoxvi.grid(row=0, column=0)
        self.scrlr2.grid(row=0, column=1)
        #Now allign the content for ctrlFrame
        self.labDir.grid(row=0, column=0, sticky=tk.E)
        self.entDir.grid(row=0, column=1)
        self.labChar.grid(row=0, column=2, sticky=tk.E)
        self.entChar.grid(row=0, column=3)
        self.btFind.grid(row=0, column=4)
        self.btExit.grid(row=0,column=5)

    def findallfiles(self, base):
        pass

    def fillboxes(self):
        pass

    def quitEvent(self):
        raise SystemExit

app = Theapp()
app.mainWindow.mainloop()

######End Code#######

I have only posted the code relevant to the GUI.
