Hi all Before beeing able to vote I should understand: How do formatting according to #1 (using attribute 'layout') and formatting acordung to #2 (using method 'format' and string-argument '%s %s') compare? While #1 obviously is simple layout along y-axis, I cannot see in what kind of 'formatting' is specified by the string '%s %s'. What, precisely, is that string about to do, what's its meaning? Apologies, if that' a silly question.
