Depending on how much the widget is `your', either add
GDK_BUTTON_PRESS_MASK in widget's realize method:

    ...
    attributes.event_mask = gtk_widget_get_events(widget)
                            | GDK_BUTTON_PRESS_MASK
                            ...

or use gtk_widget_add_events() to add it to make the widget
receive this type of event.

gtk_drag_source_set() has to set the event when it is unset
(DnD could not work if the widget did not receive button
press events).  So, this is a side effect.
