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:
- Since gtkmm 2.12:
