POtkinter widget interface interactive button

Body
copied!<p>I am very new to interactive python programming so please bear with me. I am using PyCharm with Python 3.3. </p> <p>I am attempting to build the following:</p> <p>I want to generate an a function that pulls up interactive window with two text input fields and two buttons:</p> <p>-The first button (START) runs a small text-search function (which I already wrote and tested), while the second button (QUIT) will quit the app.</p> <p>-The first text input field takes a string to be searched (ex: "Hello Stack World"), while the other text input field takes a string to be searched within the first input string (ex: "Stack").</p> <p>The plan is that once the two text fields are filled in, pressing the 'START' button will start the text-search function, while the'QUIT' button stops the program.</p> <p>The problem is, the 'QUIT' button works the way it should, but the 'START' button does nothing. I think it actually sends my program into an infinite loop. </p> <p>Any and all help is really appreciated it. I am a novice at interface/widget programming. </p> <p>Thanks in advance!</p> <p>Here is my code as I have it now:</p> <pre><code>import tkinter from tkinter import * class Application(Frame): def text_scan(self): dataf = str(input()) '''string to be searched''' s = str(input()) ''' string to search for''' ''' ... I will leave out the rest of this function code for brevity''' def createWidgets(self): root.title("text scan") Label (text="Please enter your text:").pack(side=TOP,padx=10,pady=10) dataf = Entry(root, width=10).pack(side=TOP,padx=10,pady=10) Label (text="Please enter the text to find:").pack(side=TOP,padx=10,pady=10) s = Entry(root, width=10).pack(side=TOP,padx=10,pady=10) self.button = Button(root,text="START",command=self.text_scan) self.button.pack() self.QUIT = Button(self) self.QUIT["text"] = "QUIT" self.QUIT["fg"] = "red" self.QUIT["command"] = self.quit self.QUIT.pack({"side": "left"}) def __init__(self, master=None): Frame.__init__(self, master) self.filename = None self.pack() self.createWidgets() root = Tk() root.title("text scan") root.quit() app = Application(master=root) app.mainloop() </code></pre>
