Hi,
Personally I stopped using 'with' keyword long time ago, but there are
code fragments from the past and today I fixed a little bug showing
again that it's a evil. TCanvas in lazarus has width and height
properties while in Delphi it hasn't (at least some time ago). So the
code below leads to different results in lazarus and Delphi, at least
for design-time drawing.
procedure TControlDescendant.Paint;
begin
with Canvas do
begin
Rectangle(0, 0, Width, Height);
edn;
end;
So not only the 'with' context can silently change while the project
is evolving, it can also change while it's being ported...
I also ran into this problem while porting Delphi code
