Tooltip
From Wikipedia, the free encyclopedia
The tooltip is a common graphical user interface element. It is used in conjunction with a cursor, usually a mouse pointer. The user hovers the cursor over an item, without clicking it, and a small "hover box" appears with supplementary information regarding the item being hovered over.
[edit] Variants
A common variant, especially in older software, is displaying a description of the tool in a status bar, but such descriptions are not usually called tooltips. Another system, on old Mac OS versions, that aims to solve the same problem, but in a slightly different way, is balloon help. Microsoft invented another term, “ScreenTip”, and uses it in its end-user documentation.
[edit] Examples
Demonstrations of tooltip usage are prevalent on Web pages. Many graphical Web browsers display the title attribute of an HTML element as a tooltip when a user hovers the mouse cursor over that element; in such a browser you should be able to hover over Wikipedia images and hyperlinks and see a tooltip appear. Some browsers, notably Microsoft’s Internet Explorer, will also display the alt attribute of an image as a tooltip in the same manner; if a title attribute is also specified, it will override the alt attribute for tooltip content, however.
