Fix for issue #3481
Line.points can be defined as list of lists, tuples and
coordinates (float values)
setter method modified to check each element of the argument
list and append it to self._points accordingly
Line example file /examples/canvas/line.py updated with the new
possible way of defining points
This fixes a large number of white space errors in the examples/
directory.
When I upgraded Makefile to check the 'make style' on the examples
directory,
the output was hundreds of lines long. Currently, the output is
managable
and consists solely of "lines too long", as kv lines cannot be split.
This
commit touches an obscene number of files in trivial ways.
