Unit List
Alphabetical list of unit scopes, along with miscellaneous units that have no unit scope.
Unit Scopes
| Bde | Bde is the unit scope for the two Borland Database Engine (BDE) units. Note that BDE is deprecated. Please use newer database technologies, such as dBExpress and DataSnap. |
| Data | Unit scope for all database, database data-binding, and cloud computing related functionality. |
| Datasnap | Datasnap is the unit scope for all units that implement DataSnap functionality such as authentication, DataSnap servers, DataSnap REST clients, DataSnap proxies, HTTP layer, Midas, and related services. |
| FMX | FMX is the unit scope that contains the units and unit scopes of the FireMonkey application platform (FMX). |
| Soap | Simple Object Access Protocol (SOAP) units, typically used for Web Services development. We suggest that you consider using DataSnap technology. |
| System | Contains the Delphi run-time library (RTL) units, classes, functions, types, variables, and constants. Also contains the System.Bindings, System.Generics, and System.Win unit scopes. Note that the System unit scope and the System unit are the same. |
| Vcl | Vcl is the unit scope for the Visual Component Library (VCL). |
| Web | Provides access to development tools for Web-based applications, such as Web.CGIApp, Web.WebFileDispatcher, Web.WebBroker, Web.DBWeb, and Web.HTTPApp.IWebAppServices. |
| Winapi | Provides access to Win32 functionality. The units listed here are only a small part of the Winapi units provided in RAD Studio. For a full list of supported functionality, see the Winapi source files in the product installation directory folder (that is, either lib/win32 or lib/win64). For further help on the Winapi, see the MSDN online library |

Units
| ActnRes | Defines the single ActnRes.TStandardActions class , whose fields (such as EditCopy1) store instances of standard actions (like Vcl.StdActns.TEditCopy). These instances store the specified default titles, shortcuts, and other properties of standard actions. These values are used as the default property values when a new standard action is created in the Action List editor or Action Manager editor. |
| AdaptReq | Defines classes and interfaces for interacting with action requests and responses, WebSnap adapter requests and responses, and HTTP request messages. |
| AutoAdap |
Defines adapter classes used by WebSnap.
|
| ComApp | |
| CompProd | |
| CtlPanel | |
| DBAdapt | |
| DBAdaptImg | |
| DesignEditors | Defines the interfaces and classes used by the property editors in the IDE. To use the DesignEditors and DesignIntf units with Delphi, you need to add the following compiler option on the Compiling page in Project Options:
For more information, see the comments in the source; the DesignEditors.pas source file is liberally commented. |
| DesignIntf | Defines the interfaces and classes used by the property editors in the IDE.
To use the DesignIntf and DesignEditors units with Delphi, you need to add the following compiler option on the Compiling page in Project Options:
With C++, you need to ensure that $(BDS)\include\windows\vcl\design is added to the INCLUDE path, and that designide.bpi is added to the Requires of your package. For more information, see the comments in the source; the DesignIntf.pas source file is liberally commented. |
