Classes.ActivateClassGroup Function

Activates a group of classes that derive from TPersistent.

Pascal
function ActivateClassGroup(AClass: TPersistentClass): TPersistentClass;
C++
TPersistentClass ActivateClassGroup(TPersistentClass AClass);

The streaming system allows the classes that can be loaded and saved to be registered in separate groups. This allows the IDE to distinguish between cross-platform and Windows-only classes. Call ActivateClassGroup to activate the group of classes that contains the class specified by AClass. If AClass is in more than one group, all groups that contain the class are activated.  

ActivateClassGroup returns the class that was last used to activate a class group. 

If the requested class group cannot be activated ActivateClassGroup raises an exception.
