I meant to say:
it returns the offset FOR any given face (from window)
I also have checked that the win-offset? (after sourcing it and doing a test) does not
take into consideration the edges... so that if you compare the value returned by
win-offset and a place a face at that location within the root face , you will have an
offset equal to all nested faces without their edge sizes...
here is a patch which fixes this, I'm quite sure its been suggested before, but it was
so simple to do... It would have taken me more time to find it...
win-offset?: func [
{Given any face, returns its screen absolute offset.}
face [object!]
/local xy
][
xy: 0x0
while [face] [
if face/parent-face [
xy: xy + face/offset
if face/parent-face/edge [xy: xy + face/parent-face/edge/size]
]
face: face/parent-face
]
xy
]
HTH!!!
