ToolTips are small windows describing a tab's purpose. ToolTips are displayed if the mouse cursor stays above a tab for a certain period of time. ToolTip windows are automatically removed if the mouse cursor is moved away from the tab or if the user presses a key on the keyboard.

ToolTips are optional (see SFTTABS_CONTROL and SetToolTip) and can be defined using the SftTabs/DLL Wizard.

ToolTips are also available for scroll buttons and Minimize, Restore and Close buttons (see SFTTABS_CONTROL).

Windows Mobile Edition: ToolTips are not available, because Windows Mobile operating systems do not have a cursor/mouse position. For source code compatibility, API functions for ToolTips are available, but are ignored when used.
