GtkNotebook as GtkBuildable

The GtkNoteboopk implementation of the GtkBuildable interface supports placing children into tabs by specifying "tab" as the "type" attribute of a <child> element. Note that the content of the tab must be created before the tab can be filled. A tab child can be specified without specifying a <child> type attribute.

<object class="GtkNotebook">
  <child>
    <object class="GtkLabel" id="notebook-content">
      <property name="label">Content</property>
    </object>
  </child>
  <child type="tab">
    <object class="GtkLabel" id="notebook-tab">
      <property name="label">Tab</property>
    </object>
  </child>
</object>

Note that 2 notebooks must share a common group identificator (see gtk_notebook_set_group_id()) to allow automatic tabs interchange between them.

If you want a widget to interact with a notebook through DnD (i.e.: accept dragged tabs from it) it must be set as a drop destination and accept the target "GTK_NOTEBOOK_TAB". The notebook will fill the selection with a GtkWidget** pointing to the child widget that corresponds to the dropped tab.

   child = (void*) selection_data->data;
   
   process_widget (*child);
   gtk_container_remove (GTK_CONTAINER (notebook), *child);
 }

If you want a notebook to accept drags from other widgets, you will have to set your own DnD code to do it.

A function used by GtkNotebook when a detachable tab is dropped in the root window, it's used to create a window containing a notebook where the tab will be attached. This function will also be responsible of moving/resizing the window and adding the necessary properties to the notebook (i.e.: group-id). If the function returns NULL, the drag will be cancelled.
