Just update the source code to allow to select a specific date on Calendar gadget – and therefore on DatePicker one.
SetGadgetText() command is used to pass the date, in the following format ‘+ddmmyyyy’.
So the following
will setup – as date of the calendar – the month of March 2020, 31st day selected.
Same for DatePicker() – you can pass via SetGadgetText() a ‘+’ (plus) to select the visualized month.
As usual I will upload as soon as possible the new source
