    <p>I would like to refresh tk window when I push a button, but I have been striking out. Help would be appreciated. Below is what I have tried. I would like the tk.Label line to update when I change the input box and hit refresh, but it isn't happening.</p> <pre><code>import Tkinter as tk class MAIN(object): def __init__(self, master, **kwargs): frame = tk.Frame(master, borderwidth=5) frame.grid() et1 = tk.Entry(frame) et1.insert(0, '10') et1.grid(row=0,column=0,sticky=tk.W) tk.Label(frame, text = et1.get()).grid(row=1, column=0, sticky=tk.W) refresh = tk.Button(frame, text='Refresh', command = frame.update()) refresh.grid(row=2, column=0, sticky=tk.W) root=tk.Tk() app=MAIN(root) root.mainloop() </code></pre> <p>Any Help would be greatly appreciated. Thanks</p> <p>Edit:</p> <p>I have also tried to use the update_idletasks(), but that didn't work either.</p> <p>Answer from sc0tt's help:</p> <pre><code>import Tkinter as tk class MAIN(object): def __init__(self, master, **kwargs): frame = tk.Frame(master, borderwidth=5) frame.grid() self.et1 = tk.Entry(frame) self.et1.insert(0, 10) self.et1.grid(row=0,column=0,sticky=tk.W) self.label_contents = tk.StringVar() self.label_contents.set(self.et1.get()) tk.Label(frame, textvariable=self.label_contents).grid(row=1, column=0, sticky=tk.W) refresh = tk.Button(frame, text='Refresh', command = self.refresh_hit) refresh.grid(row=2, column=0, sticky=tk.W) def refresh_hit(self): self.label_contents.set(self.et1.get()) root=tk.Tk() app=MAIN(root) root.mainloop() </code></pre>

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.
