[Development] More Issues with QMetaObjectBuilder

[Phil Thompson]

Hi,

I've come across another issue when using QMetaObjectBuilder 
specifically related to creating properties that have a flags type.

When Q_PROPERTY is used to define a property with type (for example) 
Qt::Alignment the name of the type stored in the meta-object is 
"Qt::Alignment".

When QMetaObjectBuilder.addProperty() is used it will instead use the 
name of the meta-type (ie. "QFlags<Qt::AlignmentFlag>") which it has 
obtained from QMetaType::fromName("Qt::Alignment").name().

In the QMetaProperty ctor it tries to resolve the QMetaEnum for the 
property and uses the internal parse_scope() to extract the scope and 
qualified key from the name. However it does not handle template names 
and so fails with dynamically created properties.

One solution would be for addProperty() to always use the type name it 
was given rather than use QMetaType::fromName(). That has the advantage 
that the layout of the dynamic meta-object would match that generated by 
moc.

Another solution would be to change parse_scope() to first strip out any 
"QFlags<" and ">".

Thanks,
Phil
