single function to accept different parameter types

[J.Hilk]

@mzimmers said in single function to accept different parameter types:

@J-Hilk yes, that works when the caller of func() is a C++ function. When it's coming from QML, I get the bad_cast error.

if its coming from qml, and you're passing the object into the call, than you're essentially already passing a pointer, I think.

Try

void EquipmentModel::sendPatchRequest(Equipment *equipment)

void EquipmentModel::sendPatchRequest(Equipment *equipment)

I did try that - I get a runtime error about passing incompatible arguments. And, I'm hardly a JS expert, but I don't think there's anything I can do on the QML side to make that signature work.

One of my co-workers came up with this workaround:

// would entail one of these routines for each subclass,
// but they would all do the exact same thing.
void EquipmentModel::sendPatchRequest(const Vsp &equipment) {
    sendBaseRequest(equipment);
}

void EquipmentModel::sendBaseRequest(const Equipment &equipment)
{
    if (m_qnrPatch == nullptr) {
        int i = getIndex(equipment.m_uuid);
        if (i == NOT_IN_LIST) {
            continue;
        }
        Equipment &listEntry = *(*m_list)[i];
        equipment.addPatchFields(listEntry, qjo, rolesToKeys); // goes to subclass function.
...

It works. Unless someone comes up with a better idea, I'll close out this topic. Thanks for all the suggestions...
