Qt\4.3.0\bin\dumpcpp duplicates forward declarations, why?
Message 1 in thread
wrapperax is one of the Qt examples at
C:\Qt\4.3.0\examples\activeqt\wrapper
You may have it registered at the moment when you install Qt. if not
just type
idc wrapper.dll /regserver
in dir: C:\Qt\4.3.0\examples\activeqt\wrapper\release
Then, type
C:\Qt\4.3.0\bin\dumpcpp {3B756301-0075-4E40-8BE8-5A81DE2426B7}
wrapperaxlib.h and cpp will be generated.
Then, I included the classes in my project and compile. I got a lot of
errors.
I open wrapperaxlib.h and found “forward declarations” section was
duplicated and soothing like “struct QRect;” shouldn’t be there.
// forward declarations
struct QRect;
struct QSize;
struct QPoint;
enum MousePointer;
enum FocusPolicy;
enum ToolButtonPopupMode;
struct QRect;
struct QSize;
struct QPoint;
enum MousePointer;
enum FocusPolicy;
enum ToolButtonPopupMode;
Do you have this problem?
Thanks for your test,

Don't use dumpcpp for QAxServer servers.
QAxServer needs to generate IDL for those types, otherwise the type
library is incomplete. dumpcpp sees only the IDL, and will generate C++
from it. Both do the right thing.
Just use your C++ classes in your C++ code.
