    <p>I'm trying to use glade3 with Ruby, but unfortunately examples of this are few and far between. Looking at what's available, I've come up with the following code, but there's still something missing, as the window does not display. There doesn't seem to be any GtkBuilder 'show' method, so I'm not sure what's needed to make it appear. Does anyone know what I need to do to make this work?</p> <p>"hello.xml" is just a fairly simple glade3 xml file with a GtkWindow and a button.</p> <pre><code>#!/usr/bin/env ruby require 'rubygems' require 'gtk2' class HelloGlade attr :glade def initialize if __FILE__ == $0 Gtk.init builder = Gtk::Builder::new builder.add_from_file("hello.xml") builder.connect_signals{ |handler| method(handler) } # (I don't have any handlers yet, but I will have eventually) Gtk.main() end end def gtk_main_quit puts "Gtk.main_quit" Gtk.main_quit() end end hello = HelloGlade.new </code></pre> <p>hello.xml:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;interface&gt; &lt;requires lib="gtk+" version="2.24"/&gt; &lt;!-- interface-naming-policy project-wide --&gt; &lt;object class="GtkWindow" id="window1"&gt; &lt;property name="can_focus"&gt;False&lt;/property&gt; &lt;child&gt; &lt;object class="GtkButton" id="button1"&gt; &lt;property name="label" translatable="yes"&gt;button&lt;/property&gt; &lt;property name="visible"&gt;True&lt;/property&gt; &lt;property name="can_focus"&gt;True&lt;/property&gt; &lt;property name="receives_default"&gt;True&lt;/property&gt; &lt;property name="use_action_appearance"&gt;False&lt;/property&gt; &lt;/object&gt; &lt;/child&gt; &lt;/object&gt; &lt;/interface&gt; </code></pre> <p>(edit)</p> <p>Ugh, it's always the way. Post a question, and I figure out the answer for myself. I needed to get the window1 object from the GtkBuilder, and call its show() method:</p> <pre><code>... window = builder.get_object("window1") window.show() Gtk.main </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.
