def process_stop(color_block):
"""Handle the "stop after" checkbox.
The user wants the machine to pause after this patch. This can
be useful for applique and similar on multi-needle machines that
normally would not stop between colors.
On such machines, the user assigns needles to the colors in the
design before starting stitching. C01, C02, etc are normal
needles, but C00 is special. For a block of stitches assigned
to C00, the machine will continue sewing with the last color it
had and pause after it completes the C00 block.
That means we need to introduce an artificial color change
shortly before the current stitch so that the user can set that
to C00. We'll go back 3 stitches and do that:
"""
if len(color_block.stitches) >= 3:
color_block.stitches[-3].stop = True
# and also add a color change on this stitch, completing the C00
# block:
color_block.stitches[-1].stop = True
