Yes! That's a great explanation! Have made some progress with
my source code. But i can't get the "drag-drop" signal. Is this
realy necessary?
    
I made one mistake:
    
        gtk_drag_dest_set(treeView->treeView,
                        GTK_DEST_DEFAULT_DROP,
                        &treeView->targetEntry, 1,
                        GDK_ACTION_COPY);
    
That i changed to:
    
        gtk_tree_view_enable_model_drag_dest(
                        GTK_TREE_VIEW(treeView->treeView),
                        &treeView->targetEntry, 1,
                        GDK_ACTION_COPY);
    
And i found a helpful macro for the GtkTargetEntry:
    
treeView->targetEntry.target="GTK_TREE_MODEL_ROW";
    
by watching the Gtk+ source code. But why this macro? Are there
any more macros for this? Need to know about, cause i have to
send a special data structure to target widget.
    
Now i can drag an entire gtk tree view row. I can get the
signal "drag-data-received" and "drag-end". But if i like to
drop to the destination widget the dragged object scrolls back
to source widget. I think i need to tell the source widget that
dropping was done sucessful. How can i realize this with Gtk+?
Do i need this "drag-drop" signal?
