<br><br>The menu is not attached to any widget, nor is it strictly tied to the<br>AppView. I'm a bit surprised thet the get_parent() actually returns<br>anything, as menus should be toplevel widgets. You could print the<br>

tryng to port grsync to maemo, it's almost done really, but for this
menu related issue. Grsync has been made with Glade and Glade uses a
lookup_widget() function to retrieve widgets programmatically by their
names. It takes two input parameters: a GtkWidget reference and a
string with the name of the widget to look for. the widget reference
can be ANY widget, so the first thing it does is trying to get the "top
level" widget - ie the widget which has been used as a container of all
the others in all the g_object_set_data and g_object_set_data_full
previous calls, which in my case is the (only one) HildonAppView.
<br>If lookup_widget is invoked from one of the menu items, it first
gets a reference of its parent menu and then a reference to this
"phantom" GtkWindow (which has no parent) and that's all - no reference
to the AppView.
<br>Here is lookup_widget() code (I tweaked it a little to recognize a HildonAppView and stop looking further):<br><br>[code]<br><br>GtkWidget*<br>lookup_widget <div id="mb_3"> (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 = gtk_menu_get_attach_widget (GTK_MENU (widget)); // <- THIS DOESN'T WORK<br> parent = gtk_widget_get_parent(widget); // <- THIS RETURNS A REFERENCE TO A GtkWindow
<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><br>[/end code]</div><br>Luca Donaggio<br>
