    <p>I've been writing writing a small pygtk application using glade to put together the UIs. I've created several windows already that work, but for some reason this one isn't working. I get the following traceback:</p> <pre><code>Traceback (most recent call last): File "test.py", line 7, in &lt;module&gt; class TestClass: File "test.py", line 10, in TestClass self.wTree.signal_autoconnect(self) NameError: name 'self' is not defined </code></pre> <p>Here is the contents of test.py:</p> <pre><code>#!/usr/bin/env python import pygtk import gtk import gtk.glade class TestClass: def __init__(self): self.wTree = gtk.glade.XML("test.glade") self.wTree.signal_autoconnect(self) def on_TestClass_destroy(self, widget, data): gtk.main_quit() if __name__ == "__main__": window = TestClass() gtk.main() </code></pre> <p>And here is the glade file, test.glade:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="no"?&gt; &lt;!DOCTYPE glade-interface SYSTEM "glade-2.0.dtd"&gt; &lt;!--Generated with glade3 3.4.5 on Fri Nov 21 08:53:53 2008 --&gt; &lt;glade-interface&gt; &lt;widget class="GtkWindow" id="TestWindow"&gt; &lt;property name="visible"&gt;True&lt;/property&gt; &lt;property name="title" translatable="yes"&gt;Test Window&lt;/property&gt; &lt;signal name="destroy" handler="on_TestClass_destroy"/&gt; &lt;child&gt; &lt;placeholder/&gt; &lt;/child&gt; &lt;/widget&gt; &lt;/glade-interface&gt; </code></pre> <p>The strange thing is that if I take out the signal_autoconnect(self) call, the window opens. But if I replace that call with "self.on_TestClass_destroy(self, None, None)" instead, it returns the same NameError exception.</p> <p>I really don't understand why this isn't working, as I've created several other window classes that work fine.</p> <p>Is the following code working for anyone here?</p>

    1. COI seem to have gotten this code to work, but I don't exactly understand what I did to fix it. It seems to be a white-space related issue. I have had to change around how my editor handles tabs/spaces, so that may have been a part of the issue.

    2. COProbably. Python style guides recommend always using four spaces rather than a tab for indentation, so you should set it up that way to play nice with others.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
