Re: [Lazarus] displayiing points in a form

[Felipe Monteiro de Carvalho]

Draw to a persistent TBitmap and in the OnPaint event just draw this Bitmap:

MyFormOnCreate:
being
  MyBitmap := TBitmap.Create;
  // set bitmap size
end

MyFormDoWhatever:
begin
  //Paint to MyBitmap.Canvas
end

MyFormOrControlOnPaint:
begin
  Canvas.Draw(0, 0, MyBitmap);
end

Hope it's clear enough.
