 *
 * A hoversel is a button that pops up a list of items (automatically
 * choosing the direction to display) that have a label and, optionally, an
 * icon to select from. It is a convenience widget to avoid the need to do
 * all the piecing together yourself. It is intended for a small number of
 * items in the hoversel menu (no more than 8), though is capable of many
 * more.
 *
 * This widget inherits from the @ref Button one, so that all the
 * functions acting on it also work for hoversel objects.
 *
 * This widget emits the following signals, besides the ones sent from
 * @ref Button :
 * - @c "clicked" - the user clicked the hoversel button and popped up
 *   the sel
 * - @c "selected" - an item in the hoversel list is selected. event_info
 *   is the item
 * - @c "dismissed" - the hover is dismissed
 *
 * Default content parts of the hoversel widget that you can use for are:
 * @li "icon" - An icon of the hoversel
 *
 * Default text parts of the hoversel widget that you can use for are:
 * @li "default" - Label of the hoversel
 *
