Example

To execute the example a form with the TabSheetBox component using a data source is required. This procedure is to be assigned as the handler of the OnMouseDown event for the TabSheetBox component.

Sub TabSheetBox1OnMouseDown(Sender: Object; Args: IMouseClickEventArgs);

Var

TabS: ITabSheetBox;

Sheet: ITabSheet;

View: ITabView;

Point: IPoint;

Row, Column: Integer;

Begin

TabS := Sender As ITabSheetBox;

Sheet := TabS.Source.GetTabSheet;

View := Sheet.View;

Point := Args.pPoint;

View.HitTestCell(Point.X, Point.Y, Row, Column);

WinApplication.InformationBox("Row: " + Row.ToString + "; Column: " + Column.ToString);

End Sub TabSheetBox1OnMouseDown;

After executing the example and clicking on a cell of the TabSheetBox component, a message is displayed showing indexes of the row and the column containing this cell.
