    <p>There are a few issues with your script:</p> <p>1) A typo in your <code>execute_script()</code> function: <code>for name in been_cliked</code></p> <p>2) You are actually <em>calling</em> the <code>check()</code> function when you create your radio buttons. That's why you're seeing the windows pop up when you run your program.</p> <p>You need to change this:</p> <pre><code>radio1 = Radiobutton(app, text=name, value=name, \ variable=relStatus, command=check(file_name, relStatus)) </code></pre> <p>to this:</p> <pre><code>radio1 = Radiobutton(app, text=name, value=name, \ variable=relStatus, command=check) </code></pre> <p>See how <code>check</code> no longer has brackets? That's means you're passing the function name as an argument, instead of actually <em>calling</em> the function. Of course, you'll see an immediate problem is that you can no longer pass arguments to your callback function! That's a bigger issue. Here's a couple links to help get you started:</p> <ul> <li><a href="https://stackoverflow.com/questions/3296893/how-to-pass-an-argument-to-event-handler-python-tkinter-programming">How to pass an argument to event handler in tkinter?</a></li> <li><a href="https://stackoverflow.com/questions/6922621/how-can-i-pass-arguments-to-tkinter-buttons-callback-command">How can I pass arguments to Tkinter button&#39;s callback command?</a></li> </ul> <p>Here is the solution:</p> <p>Change this:</p> <pre><code>command=check(file_name, reStatus) </code></pre> <p>to this:</p> <pre><code>command = lambda: check(file_name, relStatus) </code></pre> <p>3) You don't actually <code>pack()</code> your radio buttons anywhere. Add something like this just after you create your radio buttons in your <code>for</code> loop: <code>radio1.pack(side='top')</code></p> <p>4) You have the same problem with your callback for your <code>Click Here</code> button. You need to change your command to not call the function, but just refer to it: <code>command = execute_script</code></p> <p>5) In <code>execute_script()</code>, make sure you <code>import subprocessing</code></p> <p>6) Are you sure you want <code>yield</code> instead of <code>return</code> in your <code>execute_script()</code> function?</p> <p>7) In all your functions, you need to make sure that <code>been_clicked</code> is global.</p> <p>I think if you fix these issues you'll be closer to getting what you're looking for. Good luck.!</p>

    1. COStrange that the `for name in been_cliked` problem doesn't result in a `NameError: global name 'been_cliked' is not defined` error since the `, command=execute_script()` is _calling_ `execute_script`.

    2. COI agree. The reason is he has `yield` instead of `return`. Using `yield` won't cause `NameError` to be raised. Not sure why that is though.

    3. COAh, the answer lies here: http://stackoverflow.com/questions/231767/the-python-yield-keyword-explained `yield` causes a generator to be returned, but until that generated is used, the code hasn't been run yet.

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.

SQuiL has stopped working due to an internal error.
