    <p>For a small timer app I want to write a GTK interface where I can set the desired time. Here is a picture of the interface:</p> <p><img src="https://i.stack.imgur.com/shq8D.png" alt="alt text"></p> <p>However, I am having trouble reading out the fields of the spin buttons. My envisaged procedure for this is the following:</p> <ol> <li>Read out the buttons using methods for each button</li> </ol> <p>Here is one of the methods that does this:</p> <pre><code># Get the fields of the spinbuttons def get_seconds(self, widget, spin): self.rSeconds = spin.get_value_as_int() </code></pre> <p>It is then called like this:</p> <pre><code> button = gtk.Button("Start") button.connect("clicked", self.get_seconds, spinnerS) </code></pre> <ol start="2"> <li>Create a timer object with the data from the buttons</li> </ol> <p>This is planned to be accomplished using this method:</p> <pre><code> # Create the timer object ... def prepare_timer(self, widget, hours, minutes, seconds, title, text): self.timer = eggTimer(hours, minutes, seconds, title, text) </code></pre> <p>Which is called here:</p> <pre><code>button.connect("clicked", self.prepare_timer, self.rHours, self.rMinutes, self.rSeconds, "some title", "some text") </code></pre> <p>Unfortunately, when running the script I get the following error message:</p> <pre><code>Traceback (most recent call last): File "GTKInterface.py", line 140, in &lt;module&gt; SpinButtonExample() File "GTKInterface.py", line 126, in __init__ button.connect("clicked", self.prepare_timer, self.rHours, self.rMinutes, self.rSeconds, "Title", "Text") AttributeError: SpinButtonExample instance has no attribute 'rSeconds' </code></pre> <p>To check whether there really is no instance of that variable, I programmed a short method to print it:</p> <pre><code> def returnS(self, widget): print self.rSeconds </code></pre> <p>And surprisingly this method <em>can</em> "see" self.rSeconds. This makes me wonder what determines the visibility of the variable. What am I doing wrong to read this out?</p>

    1. COIt's not complaining about `rSeconds`, it's complaining about `rHours`. Why don't you just read out the spin buttons in `prepare_timer`? Could you post the full program?

    2. COSorry, that was a mistake from my side. That message was from another test run. Here is the code: http://pastie.org/1255962

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.
