Function result

TComponent instance created from the clipboard data, or Nil when not found.

Description

GetComponent is an overloaded method in TClipboard used to read a TComponent instance that was previously stored to the clipboard.

GetComponent allocates a temporary TMemoryStream which is used to read the content stored to a pcfComponent clipboard format (when found). The OnFindComponentClass argument is called to retrieve the class type needed to re-create the TComponent instance. The ReadComponentFromBinaryStream routine (in LResources) is called to create the component in the return value using the arguments to the method.

The return value is Nil if there is no component on the clipboard with the Owner and Parent specified in the arguments to the method.
