A Tooltip is a pop-up window with string that appears when you hold a cursor over an item in an application. The information in the window is usually a very brief description about the item's purpose.
Every element in the C1Ribbon control has a ToolTip property, be it Ribbon Tab, Group, Group Items, QAT or Configuration Toolbar. The ribbon application below shows a tooltip on a ColorPicker when the cursor rests on it.
Tooltips can be added via the Text Menu of the floating toolbar of ribbon items.
The tooltip for an item can also be added via the Properties window.
A user can also add a tooltip to a Ribbon Item programmatically using the TooTip property of the RibbonItem class.
