TComponent Members

The following tables list the members exposed by TComponent.

FComponentStyle is the field of the ComponentStyle read-only property. 
Called when an application uses a component interface. 
Called when an application releases a component interface. 
Copies the properties of an object to a destination object. 
Sets the private, internal storage for the Name property to the string passed in NewName. 
Designates methods for storing an object's unpublished data on a stream such as a form file. 
Returns the owner of a child component being read from a stream. 
Returns the parent, or if there is no parent, returns the owner of a child component being read from a stream. 
Enumerates all child components. 
Maps a single member and an optional set of argument names to a corresponding set of integer dispatch identifiers (dispIDs). 
Returns the owner of a component. 
Retrieves the type information for an object. 
Returns the number of type information interfaces that an object provides (either 0 or 1). 
Provides access to Automation properties and methods when the component wraps an Automation object. 
Initializes the component after the form file has been read into memory. 
Forwards notification messages to all owned components. 
Responds when the component is created from the component palette. 
Returns a reference to a specified interface if the object supports that interface. 
Reads the state of the component. 
Clears or sets csAncestor state in the component's ComponentState property. 
Sets the visual ordering of a child control. 
Ensures that components inserted at design time have their design-mode flag set. 
Ensures that components inserted at design time have their design-mode flag set. 
Sets the csInline bit of the component's ComponentState property 
Sets the value of the Name property. 
Sets the parent component. 
Clears the csUpdating state in the component's ComponentState property when the component finishes updating. 
Provides the interface for a method that adds type library and version information to the Registry on components that implement COM interfaces. 
Sets the csUpdating state in the component's ComponentState property. 
Determines whether an object can be inserted into a container. 
Provides the interface for a method that validates an child component before it is inserted. 
Ensures that renaming an owned component does not create name conflict. 
Writes the state of the component. 
Responds after the last constructor has executed. 
Copies the contents of another, similar object. 
Performs any necessary actions before the first destructor is called. 
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. 
Allocates memory and constructs a safely initialized instance of a component. 
Provides the interface for a method that processes message records. 
Disposes of the component and its owned components. 
Destroys all owned components. 
Indicates that the component and its owned components are about to be destroyed. 
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. 
Executes an action. 
This is the overview for the FieldAddress method overload. 
Indicates whether a given component is owned by the component. 
Destroys an object and frees its associated memory, if necessary. 
Deallocates memory allocated by a previous call to the System::TObject::NewInstance method. 
Ensures that AComponent is notified that the component is going to be destroyed. 
Frees the interface reference for components that were created from COM classes. 
Returns a reference to the component associated by the implementing class. 
Returns a TComponent enumerator. 
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 a string used by the Object Inspector. 
Returns the containing Component. 
Verifies whether the component has a parent. 
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. 
Establishes the component as the owner of a specified component. 
Returns the size in bytes of each instance of the object type. 
Indicates whether the component implements a specified interface. 
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. 
Establishes or removes internal links that cause this component to be notified when the implementer of a specified interface is destroyed. 
Removes a specified component specified from the component's Components list. 
Disables destruction notification that was enabled by FreeNotification 
Handles exceptions in methods declared using the safecall calling convention. 
Identifies whether the component is a subcomponent. 
Returns a string containing the class name. 
Returns a string containing the unit name. 
Updates the state of an action. 
Specifies the interface reference implemented by the component. 
Indicates the number of components owned by the component. 
Indicates the position of the component in its owner's Components property array. 
Lists all components owned by the component. 
Describes the current state of the component, indicating when a component needs to avoid certain actions. 
Governs the behavior of the component. 
Contains information used by the Form designer. 
Indicates the component that is responsible for streaming and freeing this component. 
Represents information used internally by components that support COM. 
Specifies the name of the component as referenced in code. 
Stores an integer value as part of a component.
