DECLARE_DYNCREATE

  • 项目

DECLARE_DYNCREATE(class_name)

Parameters

class_name

The actual name of the class (not enclosed in quotation marks).

Remarks

Use the DECLARE_DYNCREATE macro to enable objects of CObject-derived classes to be created dynamically at run time. The framework uses this ability to create new objects dynamically, for example, when it reads an object from disk during serialization. Document, view, and frame classes should support dynamic creation because the framework needs to create them dynamically.

Add the DECLARE_DYNCREATE macro in the .H module for the class, then include that module in all .CPP modules that need access to objects of this class.

If DECLARE_DYNCREATE is included in the class declaration, then IMPLEMENT_DYNCREATE must be included in the class implementation.

For more information on the DECLARE_DYNCREATE macro, see in Visual C++ Programmer’s Guide.

Example

See the example for IMPLEMENT_DYNCREATE.
