    <p>I'm using Python and Tkinter to create a GUI for a program I'm writing, and I'm having a couple of problems.</p> <p>I have three objects descended from LabelFrame in an object descended from Frame. One of the LabelFrame descendants is two columns of corresponding Label and Entry objects.</p> <p><img src="https://i.stack.imgur.com/ZhiXa.png" alt="freq_frame example"></p> <p>The problem is that there are a varying number of Label and Entry pairs, and there can be more than fit on the screen. I need a way to make a scrollbar for this LabelFrame so that everything fits on the screen. I've tried various ways of making a Scrollbar object, but nothing seems to work. How can I bind a scrollbar to this frame?</p> <p>Also, I need to be able to refresh or reload this LabelFrame when the <code>load_message()</code> method is called, but it just redisplays the new pairs on top of the old ones (so when there are less pairs in the new set, the old set is still visible at the bottom). I've tried using <code>grid_forget()</code> but either nothing changes or the whole frame doesn't display. How can I forget this display and then redisplay it?</p> <p>Here is the code for this class:</p> <pre><code>class freq_frame(LabelFrame): def __init__(self, master = None, text = 'Substitutions'): LabelFrame.__init__(self, master, text = text) self.grid() def load_message(self): self.frequency = get_freq(message) self.create_widgets() def create_widgets(self): self.label_list = [Label(self, text = get_label(char, self.frequency[char]), justify = LEFT) for char in self.frequency.keys()] self.entry_list = [Entry(self, width = 1) for char in self.frequency.keys()] for n in range(len(self.label_list)): self.label_list[n].grid(column = 0, row = n) for n in range(len(self.entry_list)): self.entry_list[n].grid(column = 1, row = n) </code></pre> <p>If anyone can help with either of these problems, I'd appreciate it.</p> <p>Also, this question seems like it might be a little thin, but I don't know what to add. Don't hesitate to ask for more information (but be specific).</p> <p>Thanks!</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.
