    <p>Let's explain the enviroment.</p> <p>I'm building a GUI using pygtk. At some point of my code I create a gtk.ScrolledWindow and set it a name (here the code):</p> <pre><code>top_swin = gtk.ScrolledWindow() top_swin.set_name('script-desc-swin') </code></pre> <p>Later on other part of the code I need to look for this widget so I have tried this:</p> <pre><code>self.gui.get_object('script-desc-swin') </code></pre> <p>self.gui is a gtk.Builder object, it was build from a XML file created with Glade. This line is returning None, so I though that it could be that get_object() can only be used to look for objects DEFINED ON THE GLADE FILE (note that the scrolled window is being created programatically in the code, no with Glade). I tried then the gtk.Buildable.get_internal_child() method but this time I had problems using it because the documentation says that the first parameter is a gtk.Builder (so I passed my self.gui) but then I got this:</p> <pre><code> swin = gtk.Buildable.get_internal_child(self.gui, 'script-desc-swin') TypeError: descriptor 'get_internal_child' requires a 'gtk.Buildable' object but received a 'gtk.Builder' </code></pre> <p>So I tried calling get_internal_child as if it were a method of gtk.Builder (even though I checked first the documentation and realized that gtk.Builder don't implement gtk.Buildable... anyway I tried):</p> <pre><code> swin = self.gui.get_internal_child('script-desc-swin') AttributeError: 'gtk.Builder' object has no attribute 'get_internal_child' </code></pre> <p>Of course I get this, as I said gtk.Builder (self.gui) doesn't implement gtk.Buildable.</p> <p>After all this mess I have no idea about how to look for the scrolled window (or any other widget) so what I'm doing is look for a widget specified in the XML file (in other words, created with Glade), and then I get its child/children and repeting this process. This is like "OMFG! WHAT A CRAPPY CODE!" so even with my application running I really want to change that ugly code:</p> <pre><code>box = self.gui.get_object('MAIN_VIEW_BOX') hpaned = box.get_children()[1] hpaned2 = hpaned.get_child2() swin = hpaned2.get_child1() </code></pre> <p>A box containing an hpaned containing as the second child another hpaned containing as the first child THE SCROLLED WINDOW.</p> <p>Almost sure the answer will be quite simple... :-s</p> <p>Thank!</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.
