RAD Studio VCL Reference
|
Provides the interface for a method that processes message records.
procedure DefaultHandler(var Message); virtual;
virtual DefaultHandler(var Message);
System::TObject::DefaultHandler is called by System::TObject::Dispatch when it cannot find a method for a particular message. System::TObject::DefaultHandler provides message handling for all messages for which an object does not have specific handlers. Descendant classes that process messages override System::TObject::DefaultHandler according to the types of messages they handle.
