InheritedProtected
_AddRefprotectedCalled when an application uses a component interface.
_ReleaseprotectedCalled when an application releases a component interface.
AddLinkprotectedAdds the provided Link to the Links array of links.
AddOrSetpublicIt adds or replaces several files in the Source collection, and adds the item to the Destination collection if it does not exist.
AddToCacheprotectedAppends the specified Bitmap to the end of the internal cache.
AfterConstructionpublicResponds after the last constructor has executed.
Assignpublic
AssignToprotectedCopies the properties of an object to a destination object.
AsyncScheduleprotectedSchedules asynch method calls.
BeforeDestructionpublic
BeginInvokepublicPerforms an asynchronous call to the method specified by either AProc or AFunc.
BeginUpdatepublicWhen BeginUpdate is called for the first time, it sets the csUpdating state to the current list object to prevent multiple calls to DoChange.
BestSizepublicReturns the maximum size of rectangles from all layers of the specified Index image in the destination collection, that is less than the specified Size.
BitmappublicReturns the TBitmap object, in the cache, containing the image referenced with Index in the Destination collection and having the specified Size.
BitmapExistspublicReturns True if a bitmap corresponding to the Index item exists in the internal cache or the destination collection contains the Index item having not empty image.
BitmapItemByNamepublicTries to find the bitmap item specified by Name in the Source collection.
CanObserveprotected
ChangepublicCall Change after any changes in the image list.
ChangeNameprotectedSets the private, internal storage for the Name property to the string passed in NewName.
CheckDisposedprotectedThis method is deprecated.
ClassInfopublicReturns a pointer to the run-time type information (RTTI) table for the object type.
ClassNamepublicReturns a string indicating the type of the object instance (as opposed to the type of the variable passed as an argument).
ClassNameIspublicDetermines whether an object is of a specific type.
ClassParentpublicReturns the type of the immediate ancestor of a class.
ClassTypepublicReturns the class reference for the object's class.
CleanupInstancepublicPerforms finalization on long strings, variants, and interface variables within a class.
ClearCachepublicRemoves the Index bitmap from the internal cache.
Createpublic
CreateDestinationprotectedCreates a Destination collection.
CreateSourceprotectedCreates a Source collection.
DefaultHandlerpublicProvides the interface for a method that processes message records.
DefinePropertiesprotectedDesignates methods for storing an object's unpublished data on a stream such as a form file.
DeleteLinkprotectedRemoves the provided Link from the Links array of links.
Destroypublic
DestroyComponentspublicDestroys all owned components.
DestroyingpublicIndicates that the component and its owned components are about to be destroyed.
DispatchpublicCalls message-handling methods for the object, based on the contents of the Message parameter.
DisposeOfpublicDisposeOf forces the execution of the destructor code in an object.
DoBitmapprotectedCreates a bitmap by drawing bitmaps from all layers in the Index destination item.
DoChangeprotected
DoChangedprotectedCalls the OnChanged event handler. DoChanged is called a short time after one or more changes has been done to the image list just before sending notifications to all controls that use an image from this image list.
DrawpublicDraws an image from the Index item, in the Destination collection, on the specified Canvas.
DrawBitmapToCanvaspublicHelper method to draw some bitmap. DoBitmap uses this method.
EndFunctionInvokepublicBlocks the caller until the specified ASyncResult completes.
EndInvokepublicBlocks the caller until the specified ASyncResult completes.
EndUpdatepublicEndUpdate decrements the counter of started and not accomplished updates. When EndUpdate sets the counter to zero, it clears csUpdating and calls Change.
EqualspublicChecks whether the current instance and the Obj parameter are equal.
ExecuteActionpublicExecutes an action.
FieldAddresspublicReturns the address of a published object field.
FindComponentpublicIndicates whether a given component is owned by the component.
FindInCacheprotectedTries to find, in the internal cache, a bitmap with the specified Index and Size. If successful, then it returns the found bitmap, otherwise nil.
FreepublicDestroys an object and frees its associated memory, if necessary.
FreeInstancepublicDeallocates memory allocated by a previous call to the NewInstance method.
FreeNotificationpublicEnsures that AComponent is notified that the component is going to be destroyed.
FreeOnReleasepublicFrees the interface reference for components that were created from COM classes.
GetChildOwnerprotectedReturns the owner of a child component being read from a stream.
GetChildParentprotectedReturns the parent or, if there is no parent, returns the owner of a child component being read from a stream.
GetChildrenprotectedEnumerates all child components.
GetCountprotected
GetDeltaStreamsprotected
GetDisposedprotectedGetter for the Disposed property.
GetEnumeratorpublicReturns a TComponent enumerator.
GetHashCodepublicReturns an integer containing the hash code.
GetIDsOfNamesprotectedMaps a single member and an optional set of argument names to a corresponding set of integer dispatch identifiers (dispIDs).
GetInterfacepublicRetrieves a specified interface.
GetInterfaceEntrypublicReturns the entry for a specific interface implemented in a class.
GetInterfaceTablepublicReturns a pointer to a structure containing all of the interfaces implemented by a given class.
GetNamePathpublicReturns a string used by the Object Inspector.
GetObserversprotectedGetter of Observers.

HasParentpublicVerifies whether the component has a parent.
InheritsFrompublicDetermines the relationship of two object types.
InitInstancepublicInitializes a newly allocated object instance to all zeros and initializes the instance's virtual method table pointer.
