</footer><!-- /.post-info -->                <p>Yesterday I <strong>upgraded</strong> from <strong>Ubuntu 7.10</strong> to the new <strong>8.04 RC</strong> and
I "broke" my Scratchbox installation. I tried to install it again and I
had still some problems logging into <strong>Scratchbox</strong> and installing the
<strong>SDK</strong>.</p>
<p>The I found this page:
<a href="http://suppressingfire.livejournal.com/35277.html">http://suppressingfire.livejournal.com/35277.html</a></p>
<p>that explain how to fix these problems. In particular if you get this
kind of error trying to log into Scratchbox:</p>
<p><code>Inconsistency detected by ld.so: rtld.c: 1192: dl_main: Assertion `(void *) ph-&gt;p_vaddr == _rtld_local._dl_sysinfo_dso' failed!</code></p>
<p>You can fix it in this way:</p>
<p><code>echo 0 | sudo tee /proc/sys/vm/vdso_enabled</code></p>
<p>You can read the complete fix in my updated wiki:

</footer><!-- /.post-info -->                <p>In these days I was looking for a simple tutorial to understand how to
use <strong>GtkIconView</strong>, but the only thing I was able to find was an
example in PHP-Gtk. So I decided to translate it in <strong>Python</strong> language,
thinking it would be useful for other people trying to use that Gtk
control. You can find the code here:</p>
<p>[sourcecode language='python']<br>
import gtk<br>
import gobject</p>
<p>DEFAULT_IMAGE_WIDTH = 100</p>
<p># Main Window setup<br>
window = gtk.Window(gtk.WINDOW_TOPLEVEL)<br>
window.set_size_request(400, 240)<br>
window.connect("destroy", gtk.main_quit)<br>
window.set_title("Python GtkIconView Test")</p>
<p># Add a VBox<br>
vbox = gtk.VBox()<br>
window.add(vbox)</p>
<p># Setup Scrolled Window<br>
scrolled_win = gtk.ScrolledWindow()<br>
scrolled_win.set_policy(gtk.POLICY_AUTOMATIC, gtk.POLICY_AUTOMATIC)</p>
<p># Setup ListStore to contain images and description<br>
model = gtk.ListStore(gtk.gdk.Pixbuf, gobject.TYPE_STRING)</p>
<p># Create a tuple with image files<br>
immagini = ("BD786-TFR.jpg", "guido_sottozero.jpg", "IMG_0056.JPG",
"movies_card.jpg")</p>
<p>for im in immagini:<br>
try:<br>
pixbuf = gtk.gdk.pixbuf_new_from_file(im)<br>
pix_w = pixbuf.get_width()<br>
pix_h = pixbuf.get_height()<br>
new_h = (pix_h * DEFAULT_IMAGE_WIDTH) / pix_w # Calculate the
scaled height before resizing image<br>
scaled_pix = pixbuf.scale_simple(DEFAULT_IMAGE_WIDTH, new_h,
gtk.gdk.INTERP_TILES)<br>
model.append((scaled_pix, im))<br>
except:<br>
pass</p>
<p># Setup GtkIconView<br>
view = gtk.IconView(model) # Pass the model stored in a ListStore to
the GtkIconView<br>
view.set_pixbuf_column(0)<br>
view.set_text_column(1)<br>
view.set_selection_mode(gtk.SELECTION_MULTIPLE)<br>
view.set_columns(0)<br>
view.set_item_width(150)</p>
<p># Pack objects and show them all<br>
scrolled_win.add(view)<br>
vbox.pack_start(scrolled_win)<br>
window.show_all()</p>
<p>gtk.main()<br>
[/sourcecode]</p>
<p>The important thing to notice is that you have to store all the images
in a <strong>GtkListStore</strong> and pass it to the <strong>GtkIconView</strong> as <em>"model"</em>
parameter. I hope this example is clear. If you have any question,
please comment this post and I'll try to answer.</p>
<p>This is a screenshot of this example:</p>

Pedroni]{style="font-weight: bold;"}, [Brian
Fitzpatrick]{style="font-weight: bold;"} and many other.</p>
<p>I'll partecipate at the conference as speaker on May 10, with a talk on
"[PyMaemo: Python for Nokia Internet
Tablets]{style="font-weight: bold;"}". In particular I'll talk about
Maemo platform, Maemo SDK (how to install and configure it) and I'll
explain how to use the two Eclipse plugins
<a href="http://esbox.garage.maemo.org/">ESBox</a> and
<a href="http://pluthon.garage.maemo.org/">Pluthon</a>.</p>
