Description

Can be seen in Qt Creator's ButtonsBar.qml:

color: Theme.color(Theme.PanelStatusBarBackgroundColor)

First, it fails to find the type for the parameter to color(). That can be fixed by qualifying it and fixing qqmljsscope.cpp to use the last "::" rather than the first as delimiter between inner and outer type. Then, however, it generates this:

int r2_1;
QObject *r2;
QJSPrimitiveValue r2_2;
int r10;
QObject *r7;
// color: Theme.color(Theme.PanelStatusBarBackgroundColor)
// generate_LoadQmlContextPropertyLookup
// generate_LoadQmlContextPropertyLookup
while (!aotContext->loadSingletonLookup(8, &r2)) {
aotContext->setInstructionPointer(2);
aotContext->initLoadSingletonLookup(8, QQmlPrivate::AOTCompiledContext::InvalidStringId);
if (aotContext->engine->hasError())
    return QJSPrimitiveValue(QJSPrimitiveUndefined()).toVariant();
}
{
}
// generate_StoreReg
r7 = r2;
{
}
// generate_LoadQmlContextPropertyLookup
// // generate_LoadQmlContextPropertyLookup
// while (!aotContext->loadSingletonLookup(9, &r2)) {
// aotContext->setInstructionPointer(6);
// aotContext->initLoadSingletonLookup(9, QQmlPrivate::AOTCompiledContext::InvalidStringId);
// if (aotContext->engine->hasError())
//     return QJSPrimitiveValue(QJSPrimitiveUndefined()).toVariant();
// }
{
}
// generate_GetLookup
while (!aotContext->getEnumLookup(10, &r2_1)) {
aotContext->setInstructionPointer(8);
aotContext->initGetEnumLookup(10, QMetaType::fromName("Utils::Theme *").metaObject(), "Color", "PanelStatusBarBackgroundColor");
if (aotContext->engine->hasError())
    return QJSPrimitiveValue(QJSPrimitiveUndefined()).toVariant();
}
{
}
// generate_StoreReg
r10 = r2_1;
{
}
// generate_CallPropertyLookup
{
void *args[] = { nullptr, &r10 };
const QMetaType types[] = { QMetaType(), QMetaType::fromType<int>() };
while (!aotContext->callObjectPropertyLookup(11, r7, args, types, 1)) {
aotContext->setInstructionPointer(15);
aotContext->initCallObjectPropertyLookup(11);
if (aotContext->engine->hasError())
    return QJSPrimitiveValue(QJSPrimitiveUndefined()).toVariant();
}
r2_2 = {};
}
{
}
// generate_StoreReg
// r6 = r2_2;
{
}
// generate_Ret
if (r2_2.type() == QJSPrimitiveValue::Undefined)
    aotContext->setReturnValueUndefined();
return r2_2.toVariant();
