    <p>I am trying to remove an Entry field after a user gives his/her name, however, I get an error using this code:</p> <pre><code>from Tkinter import * from random import randrange class Application(Frame): def __init__(self): Frame.__init__(self) self.grid() self.nameEntry = Entry(self) self.nameEntry.grid(row=0, column=0, columnspan=4) self.setupBtn = Button(self, text = "Generate", command=self.setup) self.setupBtn.grid(row=4, column=0, columnspan=4) self.preText = Text(self, width=50, height=3, wrap=WORD) self.preText.grid(row=6, column=0, columnspan=4) self.preText.delete(0.0, END) self.preText.insert(0.0, "If you enter your name, i'll give you a random number each time!") self.statusLbl = Label(self, text="What's your name?", bg="white") self.statusLbl.grid(row=7, column=0, columnspan=4, sticky=W) def setup(self): name = self.nameEntry.get() if name != "": self.nameEntry.destroy() self.setupBtn = Button(self, text = "Roll Again", command=self.setup) self.setupBtn.grid(row=4, column=0, columnspan=4) randomNumber = randrange(10, 100) if name == "": message = "Your name please!" self.preText.delete(0.0, END) self.preText.insert(0.0, message) else: self.preText.delete(0.0, END) self.preText.insert(0.0, str(randomNumber)) Application().mainloop() </code></pre> <p>Here is the error:</p> <blockquote> <p>Exception in Tkinter callback Traceback (most recent call last):</p> <pre><code>File "C:\Python27\lib\lib-tk\Tkinter.py", line 1410, in __call__ return self.func(*args) File "C:/Users/User/Desktop/app.py", line 25, in setup name = self.nameEntry.get() File "C:\Python27\lib\lib-tk\Tkinter.py", line 2391, in get return self.tk.call(self._w, 'get') TclError: invalid command name ".45073096L.45073736L" </code></pre> </blockquote> <p>I would like to remove the name Entry field after a user enters the name and clicks the roll button. But instead of rolling, I get that error.</p> <p>Is anyone able to help me? From what I know, it is because <code>name = self.nameEntry.get()</code> is used to store into name and therefore, when I delete it, it causes a problem. Do you have a workaround for it? I am not very good and am therefore unsure of how to proceed.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
