/** Add tips to your widgets
 *
 * Basic tooltips can be realized simply by using set_tooltip_text()
 * or set_tooltip_markup() without any explicit tooltip object.
 *
 * When you need a tooltip with a little more fancy contents, like
 * adding an image, or you want the tooltip to have different contents
 * per Gtk::TreeView row or cell, you will have to do a little more work:
 *
 * - Call Gtk::Widget:set_has_tooltip(); this will
 * make GTK+ monitor the widget for motion and related events
 * which are needed to determine when and where to show a tooltip.
 *
 * - Connect to Gtk::Widget::signal_query_tooltip(). This signal
 * will be emitted when a tooltip is supposed to be shown. One
 * of the arguments passed to the signal handler is a Gtk::Tooltip
 * object. This is the object that we are about to display as a
 * tooltip, and can be manipulated in your callback using functions
 * like Gtk::Tooltip::set_icon(). There are functions for setting
 * the tooltip's markup, setting an image from a stock icon, or
 * even putting in a custom widget.
 *
 * - Return true from your query-tooltip handler. This causes
 * the tooltip to be show. If you return false, it will not be shown.
 *
 * In the probably rare case where you want to have even more control
 * over the tooltip that is about to be shown, you can set your own
 * Window which will be used as tooltip window. This works as follows:
 *
 * - Do Gtk::Widget::set_has_tooltip() and connect to
 * Gtk::Widget::signal_query_tooltip() as before.
 *
 * - Use Gtk::Widget::set_tooltip_window() to set a Gtk::Window created
 * by you as tooltip window.
 *
 * - In the query-tooltip callback you can access your window
 * using Gtk::Widget::get_tooltip_window() and manipulate it as you
 * wish. The semantics of the return value are exactly as before,
 * return true to show the window, false to not show it.
