<p>The <b>Visual Component Library</b> (<b>VCL</b>) is a visual <a href="Software_component" title="Software component">component</a>-based <a href="Object-oriented_programming" title="Object-oriented programming">object-oriented</a> <a href="Software_framework" title="Software framework">framework</a> for developing the user interface of <a href="Microsoft_Windows" title="Microsoft Windows">Microsoft Windows</a> applications. It is written in <a href="Object_Pascal" title="Object Pascal">Object Pascal</a>.

</p>

<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>

<p>The VCL was developed by <a href="Borland" title="Borland">Borland</a> for use in, and is tightly integrated with, its <a href="Delphi_(IDE)" class="mw-redirect" title="Delphi (IDE)">Delphi</a> and <a href="C%2B%2BBuilder" title="C++Builder">C++Builder</a> <a href="Rapid_Application_Development" class="mw-redirect" title="Rapid Application Development">RAD</a> tools.

</p><p>In 1995 Borland released Delphi, its first release of an <a href="Object_Pascal" title="Object Pascal">Object Pascal</a> IDE and language. Up until that point, Borland's Turbo Pascal for DOS and Windows was largely a procedural language, with minimal object-oriented features, and building UI frameworks with the language required using frameworks like <a href="Turbo_Vision" title="Turbo Vision">Turbo Vision</a> and <a href="Object_Windows_Library" title="Object Windows Library">Object Windows Library</a>. OWL, a similar framework to <a href="Microsoft_Foundation_Class_Library" title="Microsoft Foundation Class Library">MFC</a>, required writing code to create UI objects.

</p><p>A key aim of the VCL combined with the <a href="Delphi_(programming_language)" class="mw-redirect" title="Delphi (programming language)">Delphi language</a> was to change the requirements of building a user interface. (For context, the Delphi variant of Pascal had a number of innovative object-oriented features, such as properties and runtime type information, inspired by Modula and Smalltalk.) At the time, much UI code work required creating classes inheriting from other classes, and customized objects were often not reusable (for example, a button that performs a specific action cannot be reused in a different application.)<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> UI code was also complicated, forcing the programmer to understand and use the Windows API, manage GDI resources, etc.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> Finally, a visual user interface arguably should be designed visually, and yet most tools to do so - at the time, mainly Visual Basic - did so in terms of the designer outputting code, creating a fragile, un-manually-editable situation - a problem that still persists today with many UI frameworks, particularly C++-based ones such as Qt.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>

</p><p>The combination of the Delphi language and the VCL framework written in that language addressed these by:

</p>

<ul><li>A streaming framework, allowing an object and subobjects to be streamed to text or binary format - TComponent, the root class of the VCL framework</li>

<li>A form designer that saved to a stream, saving the description of the objects not the code required to create them, with objects capable of self-creation when streaming the description back in</li>

<li>Language features that allowed instances of a class to be customised without subclassing, in two ways: first, through the use of properties, allowing instances of an object to have its own fields (such as a caption) easily changed through streaming; second, by allowing events - method pointers called at specific places in code - to be handled by another object; that is, the method pointers were attached to an object instance.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> In other words, this creates "custom behaviours through delegation instead of inheritance".<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup></li>

<li>Controls that wrapped native Windows controls, in framework that managed resources<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup></li></ul>

<p>The combination of these resulted in a visual designer that streamed a description; a form (window) that constructed itself from that description, including creating all the other components on that form; and code being written in one place (methods on the form) that could be called by UI elements in response to certain actions, such as a button being clicked calling an OnClick event handler implemented in the form code. At the time this was revolutionary, while today it is an approach used by several other frameworks, such as WinForms and Cocoa.

</p><p>This also allowed new components - new visual or non-visual classes - to be written easily. The VCL is Windows-based and its implementations of common controls are wrappers of the Windows API, thus is close to the ground and fully native. New controls can be implemented from scratch or can use existing Windows controls.

</p><p>With the release of C++ Builder, the Delphi compiler could emit C++ header files for compiled Delphi-language units, and so the flexibility of the streaming, visually designed UI framework became available for C++. VCL components can in fact be written in C++, but ultimately inherit from Delphi ancestors, since the C++Builder compiler and linker can consume object and header files produced by Delphi. This was one of the first examples of cross-language compatibility, something unseen until .Net.

</p><p>Today the VCL includes several hundred visual and non-visual components, usable in both the Delphi and C++ languages.

</p>

<div class="mw-heading mw-heading2"><h2 id="Technology">Technology</h2></div>

<p>VCL forms a <a href="Class_(object-oriented_programming)" class="mw-redirect" title="Class (object-oriented programming)">class</a> hierarchy with a common <a href="Inheritance_(object-oriented_programming)" title="Inheritance (object-oriented programming)">ancestor</a>, the TComponent class (which <a href="Inheritance_(object-oriented_programming)" title="Inheritance (object-oriented programming)">inherits</a> from TObject, the root class in <a href="Delphi_(programming_language)" class="mw-redirect" title="Delphi (programming language)">Delphi</a> <a href="Object_Pascal" title="Object Pascal">Object Pascal</a>). This is a common approach shared by the <a href="Java_programming_language" class="mw-redirect" title="Java programming language">Java programming language</a>, <a href="Smalltalk" title="Smalltalk">Smalltalk</a>, <a href="C_Sharp_(programming_language)" title="C Sharp (programming language)">C#</a> and many other <a href="Object-oriented_programming" title="Object-oriented programming">object-oriented</a> programming languages.

</p><p>VCL components cover Windows controls like windows (TForm <a href="Class_(object-oriented_programming)" class="mw-redirect" title="Class (object-oriented programming)">class</a>), controls (e.g., TButton, TCheckBox, TLabel classes) as well as <a href="Database" title="Database">database</a> access (e.g., ADO or IBX components) or Internet connections (Indy components). The component approach allows programmers to extend the VCL with many visual and non-visual additional components. There is a large number of free and commercial component packages. Among them are JEDI, TMS, Developer Express, Mitov Software, Raize Software, TurboPower, IOComp, SDL, DA-SOFT Technologies and many others.

</p><p>While not all VCL components are <a href="Thread-safe" class="mw-redirect" title="Thread-safe">thread-safe</a>, VCL supports <a href="Thread_(computing)" title="Thread (computing)">multi-threading</a> too. One example is the built in multi-threading support of the <a href="OpenWire_(library)" title="OpenWire (library)">OpenWire</a> VCL library.

</p><p>VCL provides native support for PME (properties, methods and events) model at the <a href=".NET_Framework" title=".NET Framework">.NET</a> level.

</p><p>Much of the <a href=".NET_Framework" title=".NET Framework">.NET</a> design, especially WinForms, is modeled after the VCL. One of the main architects of the first Delphi versions, <a href="Anders_Hejlsberg" title="Anders Hejlsberg">Anders Hejlsberg</a>, was hired by <a href="Microsoft" title="Microsoft">Microsoft</a> and became one of the main architects of .NET. This became the subject of a lawsuit: at the time (1996), "Borland alleged that Microsoft had hired 34 Borland employees over the past 30 months in order to steal Borland trade secrets. Borland also claimed that Microsoft offered and delivered expensive lures to Borland workers. In two cases, incentives topping $1 million were involved."<sup id="cite_ref-DotNetIsDelphi_7-0" class="reference"><a href="#cite_note-DotNetIsDelphi-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> According to Zarko Gajic, the bonus was three million dollars in Anders' case.<sup id="cite_ref-DotNetIsDelphi_7-1" class="reference"><a href="#cite_note-DotNetIsDelphi-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> Many Delphi developers find C# quite familiar, due to the design similarities.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup>

<p>A cross-platform equivalent of the VCL, called <a href="Component_Library_for_Cross_Platform" title="Component Library for Cross Platform">CLX</a> (Component Library for Cross Platform), was later developed for use in <a href="Delphi_(programming_language)" class="mw-redirect" title="Delphi (programming language)">Delphi</a>, <a href="C%2B%2BBuilder" title="C++Builder">C++Builder</a> and <a href="Kylix_programming_tool" class="mw-redirect" title="Kylix programming tool">Kylix</a> in 2000–2001. However, it was abandoned.

</p><p>A second cross-platform framework, <a href="FireMonkey" title="FireMonkey">FireMonkey</a>, was integrated into Delphi and C++Builder XE2 in 2011. FireMonkey is a vector-based WPF-like framework for UIs on Windows, OSX, iOS and Android.

</p><p>The <a href="Lazarus_(IDE)" class="mw-redirect" title="Lazarus (IDE)">Lazarus</a> project has a portable (*nix, OS/X, Win32/64+wince) equivalent called <a href="Lazarus_(IDE)" class="mw-redirect" title="Lazarus (IDE)">LCL</a>, which was already working when Kylix and CLX emerged. The project maintained its course and ignored Kylix (and later FMX).
