DECLARE_DYNCREATE

Enables objects of CObject-derived classes to be created dynamically at run time.

DECLARE_DYNCREATE(class_name )

Parameters

  • class_name
    The actual name of the class.

Remarks

The framework uses this ability to create new objects dynamically. For example, the new view created when you open a new document. 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 CObject Class Topics.

注意

The DECLARE_DYNCREATE macro includes all the functionality of DECLARE_DYNAMIC.

Example

See the example for IMPLEMENT_DYNCREATE.
