Tooltips display text when the pointer pauses over a DataWindow column or control. This text can be used to explain the purpose of the column or control. To use this feature, select the column or control for which you want to create a tooltip and then select the Tooltip tab in the Properties view. You can use the tab to specify:
Text for the tooltip
Title for the tooltip
Color of the background and text
Icon for the tooltip
Delay before the tooltip appears and disappears
Whether the tooltip appears as a rectangle or callout bubble
