TcxCustomTreeList.OnGetCellHint Event

Enables you to customize a View element’s hint.

Declaration

property OnGetCellHint: TcxTreeListGetCellHintEvent read; write;

Remarks

Sender specifies the tree list.

ACell returns ViewInfo information about a tree list element whose hint is about to be shown. The following table summarizes available view elements and classes that correspond to them. Make certain to cast the ACell parameter to the appropriate class to use its members.

View Element	Associated Class
Data Cell	TcxTreeListEditCellViewInfo
Footer or Group Footer	TcxTreeListFooterCellViewInfo
Band Header or Column Header	TcxTreeListHeaderCellViewInfo

AText specifies the hint text.

ANeedShow specifies whether the hint will be displayed. By default, ANeedShow is set to False, indicating the element’s content is not clipped, and as a result, the hint should not be shown. Set ANeedShow to True to display the hint.

Note

The OnGetCellHint event fires before a hint is shown for a tree list element located under the mouse pointer. To enable hints within the tree list, use the CellHints, FooterHints and HeaderHints options within the OptionsBehavior option set.
