Hello.
I'd like to create a user attribute TUserAttribute in OCAF which inherits from TDF_Attribute, as described in OCAF user manual.
To add it in the OCAF Tree, the TDF_Label::Add( ) take a Handle_TDF_Attribute in parameter. When I try to code :
Handle(TUserAttribute) myUserAttribute;
myUserAttribute = new TUserAttribute();
myLabel.AddAttribute (myUserAttribute);
I get 'Handle_TUserAttribute' C2065 : undeclared identifier.
Do have I necessarily to create also Handle_TUserAttribute class ?
Like in Handle_TDataStdName.hxx : DEFINE_STANDARD_HANDLE(TDataStd_Name,TDF_Attribute) ..
Thank you for your answer.
