That's got nothing to do with the Object Pascal being modern or not (I
think it is modern enough). The decline is about marketing and
popularity contests, and

That would be the best solution. GUI programming is based on
fundamentals than need to be

Incidently, that is how fpGUI's latest 'develop' branch overcomes the
painting outside the Paint method problems. Seeing as AggPas is used as

I don't believe LCL uses double buffering by default (for some reason or
another). At least that is what I was told in the Lazarus Forums.

In that case I would make it a record type with RedAlpha, GreenAlpha and
BlueAlpha: Byte. Why?, Because TColor's range is way to large, with most

An then you start getting the contradicting properties.
For example:
Label1.Color := clRed;
Label1.ColorAlpha := 170;
Label1.Transparent := True;
or, what to do if Label1.Transparent

Michael, I just tried with a brand new project, dropped a large TMemo on
the form, resized the form smaller, then set AutoScroll = True, and it
worked with LCL-GTK2. So you seem to be in

I wouldn't be surprised if it only works with a specific LCL widgetset
(eg: LCL-Win32).
Could a TScrollBox (aligned alClient) be used as a work-around?
