Re: Dual Drop on to GtkTreeView

[Todd Kulesza <todd dropline net>]

Thanks for the tips.  This almost works--if I manually add an item to 
the view, I can drag other items over it and then add them to the view. 
 However, you can't drag the first item into the view, and you can't 
drag any item into the empty space at the bottom of the list.  The code 
I have is:

static const GtkTargetEntry target_table [] =
{
        { "STRING",        0, TARGET_STRING },
        { "text/plain",    0, TARGET_STRING },
        { "text/uri-list", 0, TARGET_URL },
        { "GTK_TREE_MODEL_ROW", GTK_TARGET_SAME_WIDGET, 0 }
};


        view = gtk_tree_view_new_with_model (GTK_TREE_MODEL (store));

        gtk_tree_view_enable_model_drag_source (GTK_TREE_VIEW (view),
                                        GDK_BUTTON1_MASK,
                                        target_table,
                                        G_N_ELEMENTS (target_table),
                                        DK_ACTION_MOVE|GDK_ACTION_COPY);
        gtk_tree_view_enable_model_drag_dest (GTK_TREE_VIEW (view),
                                      target_table,
                                      G_N_ELEMENTS (target_table),
                                      GDK_ACTION_MOVE|GDK_ACTION_COPY);
        g_signal_connect (G_OBJECT (view), "drag_data_received",
                        G_CALLBACK (drag_audio_rcv_cb), store);
