| == Purpose ==
| |
| A ''tool-tip'' is a small pop-up window that labels the unlabeled control being pointed to, such as toolbar controls without caption or command buttons. When providing more descriptive text the control is called ''info-tip''. Tips are a form of progressive disclosure, eliminating the need always to have descriptive text on the screen. This time-delay mechanism makes tips very convenient, but it also reduces their discoverability. When tips are used consistently they support user’s expectation and foster predictability.

| == Examples ==
| |
| | |
| == Guidelines ==
| |
| * Use tips to label unlabeled controls and to provide additional information.
| |
| * Don’t use tips for warnings.
| |
| * Keep tips brief, typically five words or less for tool-tips; whenever appropriate, provide keyboard short-cuts and default values.
| |
| * Format info-tips to make their content easier to read and scan by grouping and aligning the content. The information should be:
| |
| ** concise: large, unformatted blocks of text are difficult to read and overwhelming
| |
| ** helpful: it shouldn't be obvious or just repeat what is already on the screen)
| |
| ** supplemental: important information should be communicated using self-explanatory control labels or in-place supplemental text)
| |
| ** (in discussion) <font color="blue">static: tips should not change from one instance to the next)</font>
| |
| * (in discussion) <font color="blue">If the control is disabled, add a short explanation about the reason to the tip. Do not add information beyond that.</font>
| |
| * Consider to add small info buttons for use tips with a touch screen.
| |
| (in discussion) <font color="blue">
| |
| * Do not use icons and formattings for tips of unlabeled controls.
| |
| * Use info-tips with icons and formattings
| |
| ** if tips describe comprehensive functions,
| |
| ** when content is lengthy and formatting improves readability
| |
| ** for tips that are implemented primarily for joy of use.
