Detailed Description

GtkTooltips has been deprecated in GTK+ 2.12, in favor of the new GtkTooltip API. 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 gtkTooltipsEnable. 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 GtkWidget, 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 gtkWidgetNoWindow(). 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 gtkTooltipsDataGet. Adding tooltips to buttons.

## Let's add some tooltips to some buttons
button_bar_tips <- gtkTooltips() ## Create the buttons and pack them into a GtkHBox
hbox <- gtkHBox(TRUE, 2) load_button <- gtkButton("Load a file")
hbox$packStart(load_button, TRUE, TRUE, 2) save_button <- gtkButton("Save a file")
hbox$packStart(save_button, TRUE, TRUE, 2) ## Add the tips
button_bar_tips$setTip(load_button,
                       "Load a new document into this window",
                       paste("Requests the filename of a document.",
                             "This will then be loaded into the current",
                             "window, replacing the contents of whatever",
                             "is already loaded."))
button_bar_tips$setTip(save_button,
                       "Saves the current document to a file",
                       paste("If you have saved the document previously,",
                             "then the new version will be saved over the",
                             "old one. Otherwise, you will be prompted for",
                             "a filename.")) 

Structures

GtkTooltips
WARNING: GtkTooltips is deprecated and should not be used in newly-written code. Holds information about a group of tooltips. Fields should be changed using the functions provided, rather than directly accessing the struct's members.
GtkTooltipsData
WARNING: GtkTooltipsData has been deprecated since version 2.12 and should not be used in newly-written code. tooltips is the GtkTooltips group that this tooltip belongs to. widget is the GtkWidget that this tooltip data is associated with. tip_text is a string containing the tooltip message itself. tip_private is a string that is not shown as the default tooltip. Instead, this message may be more informative and go towards forming a context-sensitive help system for your application. (FIXME: how to actually "switch on" private tips?)

Convenient Construction

gtkTooltips is the equivalent of gtkTooltipsNew.
