Hello
Unfortunately, there is no easy way to display animated images in the grid.
But this possibility can be realized if you divide the image into separate frames and draw each frame into grid cells according to a timer.
I am attaching an example of how this feature can be implemented.
Code:
TForm1 = class(TForm)
...
private
public
Bitmaps: TList<TBitmap>;
FrameIndex: Integer;
end;
//divide the image into separate frames
Code:
procedure TForm1.Button1Click(Sender: TObject);
var
GIFImage: TGIFImage;
// BackgroundColor: TColor;
I: Integer;
begin
GIFImage := Image1.Picture.Graphic as TGIFImage;
GIFImage.Animate := True;
// BackgroundColor := GIFImage.BackgroundColor;
for I := 0 to GIFImage.Images.Count - 1 do
begin
Bitmaps.Add(GIFImage.Images[I].Bitmap);
end;
Timer1.Interval := GIFImage.AnimationSpeed;
Timer1.Enabled := True;
DBGridEh1.Invalidate;
end;
//Draw Grid Cell Data
Code:
procedure TForm1.DBGridEh1Columns0AdvDrawDataCell(Sender: TCustomDBGridEh; Cell,
AreaCell: TGridCoord; Column: TColumnEh; const ARect: TRect;
var Params: TColCellParamsEh; var Processed: Boolean);
var
DestRect: TRect;
Bitmap: TBitmap;
begin
Sender.DrawColumnDataCellBackground(Cell, AreaCell, Column, ARect, Params);
if MemTableEh1.FieldByName('Name').AsString = 'Bolivia' then
begin
if Bitmaps.Count > 0 then
begin
Bitmap := Bitmaps[FrameIndex];
DestRect := GetDestRectForImagePlacement(CreateSize(Bitmap.Width, Bitmap.Height), ARect, TImagePlacementEh.ipFitEh);
Sender.Canvas.StretchDraw(DestRect, Bitmap);
end;
end;
Processed := True;
end;
//Change FrameIndex in the Times
Code:
procedure TForm1.Timer1Timer(Sender: TObject);
begin
Inc(FrameIndex);
if FrameIndex >= Bitmaps.Count then
FrameIndex := 0;
TDBGridEhCrack(DBGridEh1).InvalidateCol(1);
end;
