Subject: Re: Showing Images inside a TDrawGrid
In reply to: Juan 's message, "Showing Images inside a TDrawGrid" on 20:19:12 04/18/00 Tue

Hi Juan,

I do not have an example to show images inside a TDrawGrid and I have not used the TDrawGrid very much.

From the documentation, I see that the OnDrawCell event must be used to draw a cell, using the Canvas property of the Sender parameter. This is untested code similar to one in the on line help:

procedure TForm1.DrawGrid1DrawCell(Sender: TObject; Col, Row: Longint; Rect: TRect; State: TGridDrawState);

begin
with Sender as TDrawGrid do
begin
Canvas.Brush.Color := clBackGround;
Canvas.FillRect(Rect);

{ assume you have an image in a TPngGraphic }

Canvas.Draw(Rect.Left,Rect.Top,PngGraphic);

if gdFocused in State then
Canvas.DrawFocusRect(Rect);
end;

end;

This should work to draw any graphic derived from TGraphic, including all Envision classes derived from TDibGraphic.

Best regards,

Michel
