Description 
 
Copies the properties of an object to a destination object. 
 
Generates an OnChange event when the properties of the graphics object change. 
 
Provides an interface for a method that reads and writes otherwise unpublished data. 
 
This is GetColor, a member of class TPen. 
 
This is GetHandle, a member of class TPen. 
 
Returns the owner of an object. 
 
This is GetStyle, a member of class TPen. 
 
This is GetWidth, a member of class TPen. 
 
Lock 
Blocks other execution threads from using the associated canvas until the Unlock method is called. 
 
This is SetColor, a member of class TPen. 
 
This is SetHandle, a member of class TPen. 
 
This is SetMode, a member of class TPen. 
 
This is SetStyle, a member of class TPen. 
 
This is SetWidth, a member of class TPen. 
 
Releases the lock on execution threads set by the Lock method. 
 
Name 
Description 
 
Occurs immediately after the graphics object changes. 
 
Name 
Description 
 
Responds after the last constructor has executed. 
 
Assigns the properties of the pen from another TPen object. 
 
Responds before the first destructor executes. 
 
Returns a pointer to the runtime type information (RTTI) table for the object type. 
 
Returns a string indicating the type of the object instance (as opposed to the type of the variable passed as an argument). 
 
Determines whether an object is of a specific type. 
 
Returns the type of the immediate ancestor of a class. 
 
Returns the class reference for the object's class. 
 
Performs finalization on long strings, variants, and interface variables within a class. 
 
Creates an instance of TPen
 
Provides the interface for a method that processes message records. 
 
Destroys an instance of TPen
 
Calls message-handling methods for the object, based on the contents of the Message parameter. 
 
Checks if the current instance and the parameter are equal. 
 
This is the overview for the FieldAddress method overload. 
 
Free 
Destroys an object and frees its associated memory, if necessary. 
 
Deallocates memory allocated by a previous call to the System::TObject::NewInstance method. 
 
Returns an integer containing the hash code. 
 
Retrieves a specified interface. 
 
Returns the entry for a specific interface implemented in a class. 
 
Returns a pointer to a structure containing all of the interfaces implemented by a given class. 
 
Returns the name of the object as it appears in the Object Inspector. 
 
Indicates whether the TGraphicsObject object has acquired a handle to the underlying GDI object. 
 
Determines the relationship of two object types. 
 
Initializes a newly allocated object instance to all zeros and initializes the instance's virtual method table pointer. 
 
Returns the size in bytes of each instance of the object type. 
 
This is the overview for the MethodAddress method overload. 
 
Returns the name of a class method by address. 
 
Allocates memory for an instance of an object type and returns a pointer to that new instance. 
 
Handles exceptions in methods declared using the safecall calling convention. 
 
Returns a string containing the class name. 
 
Returns a string containing the unit name. 
 
Name 
Description 
 
Specifies the Windows pen object handle. 
 
Points to information about the critical section that the canvas which draws with this graphics object uses to lock out other threads. 
 
Name
