Can't autocomplete on ImageProcessor #10

Closed acardona closed 2 years ago

acardona commented 2 years ago

The code:

from ij import IJ

imp = IJ.getImage()
ip = imp.getProcessor()

ip.

... followed by control+space to autocomplete, fails. The error is interesting, and has to do with the ordering of the fields and methods

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: Comparison method violates its general contract!

Seems to indicate that the internal machinery of the org.fife package is pulling an A == B, B ==C, but A != C somewhere.

This code followed by control+space doesn't fail:

from ij import IJ

imp = IJ.getImage()
ip = imp.getProcessor()

ip.g

It's only when the ip. is left to fully expand the whole list.

This code doesn't fail:

from ij import IJ

imp = IJ.getImage()
ip = imp.getProcessor()

imp.

... so it's specific of the listing of fields and methods of ImageProcessor.
