Shell tool: Qt enum vs. int

[Tristan Croll]

The following bug report has been submitted:
Platform:        Linux-5.15.0-53-generic-x86_64-with-glibc2.35
ChimeraX Version: 1.5 (2022-11-24 00:03:27 UTC)
Description
Ran into an obscure bug in the QT console while messing with RDKit. Reproducible with the following code in the console:

{{{
def rdkit_mol_from_chimerax_residue(residue):
    from rdkit.Chem.rdchem import Mol, EditableMol, Atom, Conformer
    from rdkit.Geometry import Point3D
    rm = Mol()
    em = EditableMol(rm)
    atoms = residue.atoms
    for ca in atoms:
        ra = Atom(ca.element.name)
        em.AddAtom(ra)

    for cb in atoms.intra_bonds:
        i1, i2 = [atoms.index(a) for a in cb.atoms]
        em.AddBond(i1, i2)

    rm = em.GetMol()

    c = Conformer(rm.GetNumAtoms())
    for i, a in enumerate(atoms):
        c.SetAtomPosition(i, Point3D(*a.coord))

    rm.AddConformer(c)
    return rm


from rdkit.Chem.Draw import IPythonConsole

IPythonConsole.ipython_useSVG=True

r = session.models[0].residues[0]

rr = rdkit_mol_from_chimerax_residue(r)

rr
}}}

Seems more of a bug in the Qt bindings than in the console, to be honest (it only accepts an int as the first argument, not an element of the Qt `ResourceType` enum). Can be worked around by editing line 269 of qtconsole.rich_jupyter_widget.py from:

{{{
        document.addResource(QtGui.QTextDocument.ImageResource,
}}}

to:
{{{
        document.addResource(QtGui.QTextDocument.ImageResource.value,
}}}

Not sure if I should be reporting this to the QtConsole devs since it looks like they're not officially supporting PyQt6 yet.

[Eric Pettersen]

There are newer version of qtconsole and qtpy that we will be trying out now that 1.5 is released. Maybe they will help.

[Tom Goddard]

PyQt6 and PySide6 handle wrap enums differently. I think PyQt6 is doing it old style representing them as int values, while PySide6 in version 6.4 switched to using Python enums (causing some havoc).

[Eric Pettersen]

It's the reverse (PyQt6: enums, PySide6: ints).

[Eric Pettersen]

Works for me in the current daily build, and the result is quite cool!

[Eric Pettersen]

On Mac, in case that's relevant.
