Component > New Component

Use this wizard to create a new component for Delphi or C++Builder. The personality of your current project is detected and used for the component.

Note: Not all of the features described here are present for every instance of the wizard.

Personality, Framework, and Platform page

This initial page is displayed (Personality, Framework, and Platform) only if you do not have a project open when you invoke the wizard. If you have a project open when you invoke this wizard, this initial page is not displayed, and the personality, framework, and platform are derived from your current project settings.


This initial page displays the available personalities (Delphi or C++), frameworks (VCL or FireMonkey), and platforms (such as Win32). Specify the personality, framework, and platform that you want the component to use:

  • VCL for C++ Win32 - supported in Win32 and Win64 applications*
  • FireMonkey for C++ - supported in Win32, Win64, OS X, iOS, and Android applications
  • VCL for Delphi Win32 - supported in Win32 and Win64 applications*
  • FireMonkey for Delphi - supported in Win32, Win64, OS X, iOS, and Android applications
Note: For Win64 applications you need to create a 32-bit version of your component on this page of the wizard. Later you should compile your component again, as a Win64 component, by setting the Target Platform to be Win64 (in the Projects Window). RAD Studio saves output files (such as .bpl and .dcp) in platform-specific directories located inside your project output directory.
