Why Canvas.Line result depends on widgetset

[Valdas]

Hello,

start a new project and add this code in to OnPaint event of the form:

canvas.MoveTo(1, 10);
canvas.LineTo(2, 10);

In Qt, Qt5 widgetset I get line 2 pixels long, in Gtk2 widgetset I get line 1 pixels long. I cant get clear explanation from Google about that issue. Is this a known bug?

That is a known feature yes, For example setting the canvas.antialise property to true has an effect on QT for sure but none on windows. lcl is a light wrapper around those widgetsets and as such it comes with the widget set's pros and cons as well.
