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.
An individual tooltip belongs to a group of tooltips. A group is created with a call to
gtkTooltipsNew. Every tooltip in the group can then be turned off with a call to
gtkTooltipsDisable and enabled with
The length of time the user must keep the mouse over a widget before the tip is shown, can be altered with
gtkTooltipsSetDelay. This is set on a 'per group of tooltips' basis.
To assign a tip to a particular
gtkTooltipsSetTip is used.
PLEASE NOTE: Tooltips can only be set on widgets which have their own X window and
receive enter and leave events.
To check if a widget has its own window use
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.
The default appearance of all tooltips in a program is determined by the current GTK+ theme that the user has selected.
Information about the tooltip (if any) associated with an arbitrary widget can be retrieved using
