- Changed all the methods called by buttons on the splitter module to use a
list of args, instead of a single argument called notUsed. This was needed to
the new buttons that the code is using.
- Replaced all the Button objects of the splitter submodule by the new buttons
that allow the user to cancel the click processing by finishing the click
outside the button.
- Changed the splitter submodule scroll view to use the empty effect class,
hence improving its visual.
- Adding heritage file.
