<br>> the HildonApp object.<br><br>This sounds a bit strange, since the HildonApp is a GtkWindow (though<br>the type and name should state HildonApp of course) which has multiple<br>HildonAppViews (derives from GtkBin) as it's children (although it

<br>If this is the case, I don't see any other way to solve the problem apart from maintaining a global reference for the HildonApp and modifying the glade lookup function to get the right pointer to the HildonAppView through that reference directly, without traversing one object's hierarchy anymore.

</span></blockquote></div><br>Ok, i finally managed to solve this issue, next week I'm planning to have the packaging work finished too and to release an hildonized version of grsync for all you rsync-lovers !<br><br>For those interested (if any ;-)):
<br><br>-first I had to manually add a reference to the HildonAppView to its GtkMenu context:<br><br>[code]<br>GLADE_HOOKUP_OBJECT_NO_REF (GTK_WIDGET (menu1), main, "main");<br><br>[/end code]<br><br>- secondly, this is the working modified version of the original glade function lookup_widget():
<br><br>[code]<br>GtkWidget*<br>lookup_widget (GtkWidget *widget,<br> const gchar *widget_name)<br>{<br> GtkWidget *parent, *found_widget;<br><br>
for (;;)<br> {<br> if (GTK_IS_MENU (widget)) {<br> parent = (GtkWidget*) g_object_get_data (G_OBJECT (widget), "main");<br> } else if (HILDON_IS_APPVIEW (widget))<br> break;<br> else
<br> parent = widget->parent;<br> if (!parent)<br> parent = (GtkWidget*) g_object_get_data (G_OBJECT (widget), "GladeParentKey");<br> if (parent == NULL)<br> break;<br> widget = parent;
<br> }<br><br> found_widget = (GtkWidget*) g_object_get_data (G_OBJECT (widget),<br> widget_name);<br> if (!found_widget)<br> g_warning ("Widget not found: %s", widget_name);
<br> return found_widget;<br>}<br>[/end code]<br><br>Thanks Fred and Kalle for all your helpful suggestions!<br><br>Luca Donaggio.<br>
