So the GtkWindow, which is the top level widget of an HildonAppView's own menu, is not in any way referrable to the HildonApp to which that HildonAppView is attached? 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.

[maemo-developers] Way to get a reference to parent HildonAppView from its menu
How can I get a reference to the parent AppView giving a pointer to its GtkMenu?gtk_menu_get_attach_widget() doesn't work and gtk_widget_get_parent() returns a pointer to some unknown object (I checked it). Thanks in advance,Luca Donaggio ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Luca Donaggio wrote: How can I get a reference to the parent AppView giving a pointer to its GtkMenu? ...but best would be to determine if there was a way around it. What exactly is the use case? gtk_menu_get_attach_widget() doesn't work and gtk_widget_get_parent() returns a pointer to some unknown object (I checked it). The menu is not attached to any widget, nor is it strictly tied to the AppView. I'm a bit surprised thet the get_parent() actually returns anything, as menus should be toplevel widgets. You could print the name of the widget with gtk_widget_name() and the type with G_OBJECT_TYPE_NAME() to see what it is. As you see, the menu has no good connection to the view it belongs to, so it's probably better to rethink what you are doing in a different way if possible. -- Kalle Vahlman, [EMAIL PROTECTED] Powered by http://movial.fi Interesting stuff at http://syslog.movial.fi ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
