OK, finally I can see my beginners mistakes:
(1) I did declare AUTOSCALEALL after the view definitions in the designer -
it has to be in THE FIRST LINE (ok, too lazy to read all the manuals before...
)
(2) It seems to me that the textsize has to be declared in the designer script, like
"lblDate.TextSize = 16", then it will be autoscaled, also when it is programmatically set.
If the textsize is only set in the Main window of the designer it seems not to work, so that is were my confusion came from.
The second point is not clearly mentioned in the tutorials (if I did not overlook it...) and should be stressed.
Thanks for the support and the phantastic B4A !
