推荐答案
您可以使用 TDrawGrid
(或 TStringGrid
),它支持所有者绘图,并执行
You could use a TDrawGrid
(or a TStringGrid
), which supports owner-drawing, and do
procedure TForm1.FormCreate(Sender: TObject);
begin
FBg := TBitmap.Create;
FBg.LoadFromFile('C:\Users\Andreas Rejbrand\Pictures\Sample.bmp');
end;
其中 FBg
是一个 TBitmap
(例如在表单类中),然后执行
where FBg
is a TBitmap
(in the form class, for instance), and then do
procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
Rect: TRect; State: TGridDrawState);
var
r: TRect;
begin
if not (Sender is TStringGrid) then Exit;
BitBlt(TStringGrid(Sender).Canvas.Handle,
Rect.Left,
Rect.Top,
Rect.Right - Rect.Left,
Rect.Bottom - Rect.Top,
FBg.Canvas.Handle,
Rect.Left,
Rect.Top,
SRCCOPY);
if gdSelected in State then
InvertRect(TStringGrid(Sender).Canvas.Handle, Rect);
r := Rect;
TStringGrid(Sender).Canvas.Brush.Style := bsClear;
DrawText(TStringGrid(Sender).Canvas.Handle,
TStringGrid(Sender).Cells[ACol, ARow],
length(TStringGrid(Sender).Cells[ACol, ARow]),
r,
DT_SINGLELINE or DT_VCENTER or DT_END_ELLIPSIS);
end;
