[Interest] Sharing enums between ActiveQt classes

[S R]

Hi.  I am having trouble using the same enum in multiple classes with
ActiveQt.


1. If I define the enum (TestEnum) in class QClass1, properties and slots
in class QClass1 that use TestEnum work well.

a) I define the enum TestEnum publicly in class QA.

b ) Then, I include Q_ENUMS(TestEnum) to register the enum to the
meta-object system.

c)  I include the QAXCLASS(QClass1) macro to make class QClass1 available
in the created DLL.

d) If I look at the generated idl, I see the enumeration.  Properties and
public slots are available as COM properties and methods.  Everything seems
good.


2. However, I am unable to use the enum defined in class QClass1 in another
class QClass2.

a) I reference TestEnum  in properties and public slots like
QClass1::TestEnum.

b) Everything compiles without error.  MOC seems happy with the syntax.

c) However, properties and methods in QClass2 that use the QClass1 enum are
excluded from the COM object.  If I examine the generated IDL file, I see
that the generated slots and properties are commented out.  For example, I
see "/****** Property is of unsupported datatype" before properties that
use the enum.


3. I have tried as many variations as I can think of.  For example...

a) If I move the enum from QClass2 to QClass1, then I see the problem in
reverse.  The properties and methods of QClass2 seem fine but QClass1 now
shows "unsupported datatype".  This seems to confirm that I have not made
some trivial error in QClass2.

b) I have sprinkled lots of variations of Q_DECLARE_METATYPE and
qRegisterMetaType around but nothing seems to help.  Maybe I am doing this
incorrectly or in the wrong place.

c) I rearranged the order of declarations, QAXCLASS macros, etc.  Nothing
seemed to help.

d) I spent some time looking at the qaxserver.cpp source code but without
learning anything.  From that, I don't see how one class could know about
another enums from another class.

I have simplified my example, but my ideal would be to have the enums
globally available to every class in my DLL.  I am artificially associating
their definition with a single class; conceptually, they would be global.

Is what I am trying to do possible?  What am I missing?  This does not seem
like an unusual situation.

Thanks,
Sam
