They make the application easier to use by displaying messages when the user moves the mouse pointer over an onscreen element, such as a Button control. The following image shows ToolTip text that appears when the user hovers the mouse pointer over a button: When the user moves the mouse pointer away from the component or clicks the mouse button, the ToolTip disap- pears. If the mouse pointer remains over the component, the ToolTip eventually disappears. The default behavior is to display only one ToolTip at a time. You can set the time it takes for the ToolTip to appear when a user moves the mouse pointer over the component. You can also set the amount of time it takes for the ToolTip to disappear. If you define a ToolTip on a container, the ToolTipManager displays the parent's ToolTip for the children if the child does not have one.
