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 named 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.
