Hi all,
Lazarus auto generated the following code for my class:
procedure TPainter.SetFont(AValue: TFont);
begin
if FFont=AValue then Exit;

My question is, why the "if" clause needed? Is there any performance benefits?
Thanks,

Please post a feature request.
I think one event
TOnProgressEvent = (Sender : TObject; BytesRead,ContentLength : Int64) of object;
should be enough.

Hello,
Some times, we need to resume a download. To do this is very easy, enough
read byte by byte and continuing from the last 50KB (Chrome and Firefox
works so).
So, TFPHttpClient allow to read byte by byte of a content?
Thank you!

Hello,
First, sorry for my various requests. I'm contributing to improves this
beautiful class.
So, how to show a download progress?
I think that the method "ReadResponse" should have two callbacks, like as
"AContentLenght" and "AContentPosition". What do you think?
Thank you!
