    Hi,
    For some observers I need the decomposed, removeOverlaped glyph.
    I have sort of a solution by adding duplicate glyphs to the font and decompose, removeOverlap them. And automatically remove them when the observer was removed.
    But I know this can be done in a nicer way. But this code doesn’t do the trick. But way not? Seems okay to me…

    f = CurrentFont()

    g = f['H']

    temp = g.copy()
    temp.decompose()
    temp.removeOverlap()
    for c in temp.components:
    print c #these must be gone...
    drawGlyph(temp)

    <Component for I>
    <Component for I>
    Traceback (most recent call last):
    File "<untitled>", line 10, in <module>
    File "main.py", line 29, in drawGlyph
    File "lib/fontObjects/robofabWrapper.pyc", line 2736, in draw

    TypeError: 'NoneType' object has no attribute '__getitem__'

    Who can help?
    Thanks! Thom

    A copy has no parent anymore… so it cannot find the referenced glyph in a component. So decompose will not work.

    Maybe the best option is to set the parent in the copied glyph:

    source = CurrentGlyph()
g = source.copy()
g.setParent(source.getParent())

    Hi,

    OK it draws. But still overlapped, and composed…

    owke, this is idd not working cause a weakref object has to be referenced once or more.

    you could force it with:

    g = CurrentGlyph()

copy = g.copy()

# get the internal font and set it hard in the internal glyph object, even it is a copy
copy.naked().setParent(g.naked().getParent())

copy.decompose()
copy.removeOverlap()


print copy.components
