Wish B4XDateTemplate (library XUI View version 2.66)

It would be very useful to make it possible to instantiate this class, possibly customizing the B4XView size.

Currently, the class initializes the B4XView with
Width = 320dip
Height = 300dip

And if you try to resize the contained panels,
the days canvas is NOT resized
(the boxW, boxH constants are NOT updated).

Note: The Resize method is NOT present.

What do you recommend?

B4XDateTemplate is indeed not resizable. There are several alternative implementations: https://www.b4x.com/android/forum/pages/results/?query=date+template&prefix=1,2,3,17,24,29

Or take the source code from XUI Views.b4xlib (it is a zip file) and create your own modification.
