-index index

This option is used to set a tooltip on a menu item. The index may be either the entry index or the entry label. The widget must be a menu widget but the entries do not have to exist when the tooltip is set.

-items items

This option is used to set a tooltip for canvas, listbox or ttk::treview items. For the canvas widget, the item must already be present in the canvas and will be found with a find withtag lookup. For listbox and ttk::treview widgets the item(s) may be created later but the programmer is responsible for managing the link between the listbox or ttk::treview item index and the corresponding tooltip. If the listbox or ttk::treview items are re-ordered, the tooltips will need amending.

If the widget is not a canvas, listbox or ttk::treview then an error is raised.

-tab tabId

The -tab option can be used to set a tooltip for a ttk::notebook tab. The tab should already be present when this command is called, or an error will be returned. The widget must be a ttk::notebook widget.

-tag name

The -tag option can be used to set a tooltip for a text widget tag. The tag should already be present when this command is called, or an error will be returned. The widget must be a text widget.

The -- option marks the end of options. The argument following this one will be treated as message even if it starts with a -.
