怎样使鼠标移动时，相应的单元里的文字变色？
解决：
var
FTrackItem: TcxCustomGridTableItem;
FTrackRec: TcxCustomGridRecord;
procedure TForm1.cxGrid1DBTableView1CustomDrawCell(
Sender: TcxCustomGridTableView; ACanvas: TcxCanvas;
AViewInfo: TcxGridTableDataCellViewInfo; var ADone: Boolean);
begin
if (AViewInfo.GridRecord = FTrackRec) and (AViewInfo.Item = FTrackItem) then
begin
ACanvas.Font.Color := clred; //红色字体
ACanvas.Font.Style := [fsUnderline];//带下划线
end;
end;
procedure TForm1.cxGrid1DBTableView1MouseMove(Sender: TObject;
Shift: TShiftState; X, Y: Integer);
var
AHitTest: TcxCustomGridHitTest;
ATrackItem: TcxCustomGridTableItem;
ATrackRec: TcxCustomGridRecord;
begin
ATrackItem := FTrackItem;
ATrackRec := FTrackRec;
AHitTest := (Sender as TcxGridSite).GridView.ViewInfo.GetHitTest(X, Y);
if AHitTest is TcxGridRecordCellHitTest then
begin
FTrackItem := TcxGridRecordCellHitTest(AHitTest).Item;
FTrackRec := TcxGridRecordCellHitTest(AHitTest).GridRecord;
end
else
begin
FTrackItem := nil;
FTrackRec := nil;
end;
if (ATrackItem <> FTrackItem) or (ATrackRec <> FTrackRec) then
begin
// Invalidate old cell
if ATrackRec <> nil then
ATrackRec.Invalidate(ATrackItem);
// Invalidate new cell
if FTrackRec <> nil then
FTrackRec.Invalidate(FTrackItem);
end;
end;
