An object for managing a collection of tooltips.
Tooltips are the messages that appear next to a widget when the mouse pointer is held over it for a short amount of time. They are especially helpful for adding more verbose descriptions of things such as buttons in a toolbar.
Tooltips can only be set on widgets which have their own X window. To add a tooltip to a widget that doesn't have its own window, place the widget inside a GtkEventBox and add a tooltip to that instead.
GtkTooltips ();-- Creates a new tooltips object.
disable() Disables the tooltips. enable() Enables the tooltips. force_window() Internal use only. set_delay() Set the amount of time until the tips appear. set_tip() Set the tooltip for a widget.
