The Lazarus Component Library, abbreviated LCL, is a visual software component library for the Lazarus IDE.
The Lazarus Component Library, abbreviated LCL, is a visual software component library for the Lazarus IDE.
The LCL consists of a collection of units that provide components and classes especially for visual tasks. It is based on the Free Pascal libraries RTL and FCL. By binding platform-specific widgetsets it supports platform-sensitive software development for several operating systems including Android, Desktop Linux, Mac OS X and Windows. Lazarus source code files is under a mix of licenses: GNU General Public License, version 2 (GPLv2), a modified LGPL, and the MPL. [1]
It was reported on the GitHub Lazarus repository on 26 August 2013 (latest information as of September 2014 [update] ) that the LCL supported Linux (gtk, gtk2 and qt4), all flavors of Windows including WinCE, Mac OS X (carbon, gtk, qt4), and FreeBSD (gtk, gtk2), with experimental support for Solaris and the native Pascal backend fpgui which runs on Windows, WinCE and Linux.

An integrated development environment (IDE) is a software application that provides comprehensive facilities for software development. An IDE normally consists of at least a source-code editor, build automation tools, and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not.
Gambas is the name of an object-oriented dialect of the BASIC programming language, as well as the integrated development environment that accompanies it. Designed to run on Linux and other Unix-like computer operating systems, its name is a recursive acronym for Gambas Almost Means Basic. Gambas is also the word for prawns in the Spanish, French, and Portuguese languages, from which the project's logos are derived.
Component Library for Cross Platform (CLX), is a cross-platform visual component-based framework for developing Microsoft Windows and Linux applications. It is developed by Borland for use in its Kylix, Delphi, and C++ Builder software development environment.
Delphi is a general-purpose programming language and a software product that uses the Delphi dialect of the Object Pascal programming language and provides an integrated development environment (IDE) for rapid application development of desktop, mobile, web, and console software, currently developed and maintained by Embarcadero Technologies.
Free Pascal Compiler (FPC) is a compiler for the closely related programming-language dialects Pascal and Object Pascal. It is free software released under the GNU General Public License, with exception clauses that allow static linking against its runtime libraries and packages for any purpose in combination with any other software license.
PyQt is a Python binding of the cross-platform GUI toolkit Qt, implemented as a Python plug-in. PyQt is free software developed by the British firm Riverbank Computing. It is available under similar terms to Qt versions older than 4.5; this means a variety of licenses including GNU General Public License (GPL) and commercial license, but not the GNU Lesser General Public License (LGPL). PyQt supports Microsoft Windows as well as various kinds of UNIX, including Linux and MacOS.
Borland Kylix is a compiler and integrated development environment (IDE) formerly sold by Borland, but later discontinued. It is a Linux software development environment based on Borland Delphi and Borland C++ Builder, which runs under Microsoft Windows. Continuing Delphi's classical Greek theme, Kylix is the name for an ancient Greek drinking cup. The closest supported equivalent to Kylix is the free Lazarus IDE package, designed to be code-compatible with Delphi. As of 2010 the project has been resurrected in the form of Delphi cross compiler for Mac and Linux, as shown in the Embarcadero's Delphi and C++ Builder roadmap. As of September 2011 with Kylix discontinued the framework for cross-platform development by Embarcadero is FireMonkey.
A graphical user interface builder, also known as GUI designer or sometimes RAD IDE, is a software development tool that simplifies the creation of GUIs by allowing the designer to arrange graphical control elements using a drag-and-drop WYSIWYG editor. Without a GUI builder, a GUI must be built by manually specifying each widget's parameters in the source code, with no visual feedback until the program is run. Such tools are usually called the term RAD IDE.
Microsoft Compiled HTML Help is a Microsoft proprietary online help format, consisting of a collection of HTML pages, an index and other navigation tools. The files are compressed and deployed in a binary format with the extension .CHM, for Compiled HTML. The format is often used for software documentation.
Lazarus is a free, cross-platform, integrated development environment (IDE) for rapid application development (RAD) using the Free Pascal compiler. Its goal is to provide an easy-to-use development environment for programmers developing with the Object Pascal language, which is as close as possible to Delphi.
The Visual Component Framework (VCF) is an abandoned open source project for development under Microsoft Windows and Apple Macintosh that is distributed under the BSD license. It is an advanced C++ application framework that makes it easier to produce GUI-based C++ applications. The framework is C++ design and has built in support for rapid application development. The framework is designed to be portable over multiple platforms and compilers.
PeaZip is a free and open-source file manager and file archiver for Microsoft Windows, ReactOS, Linux, MacOS and BSD by Giorgio Tani. It supports its native PEA archive format and other mainstream formats, with special focus on handling open formats. Version 8.6.0 supported 226 file extensions.
MonoDevelop was an open-source integrated development environment for Linux, macOS, and Windows. Its primary focus is development of projects that use Mono and .NET Framework. MonoDevelop integrates features similar to those of NetBeans and Microsoft Visual Studio, such as automatic code completion, source control, a graphical user interface (GUI) and Web designer. MonoDevelop integrates a Gtk# GUI designer called Stetic. It supports Boo, C, C++, C#, CIL, D, F#, Java, Oxygene, Vala, JavaScript, TypeScript and Visual Basic.NET. Although there is no word from the developers that is has been discontinued, nonetheless it hasn't been updated in 4 years and is no longer installable on major operating systems, such as Ubuntu 22.04 and above. Its parent Microsoft, seems to have shifted focus to Visual Studio Code and the .NET Framework, which runs on many operating systems, including Linux.
fpGUI, the Free Pascal GUI toolkit, is a cross-platform graphical user interface toolkit developed by Graeme Geldenhuys. fpGUI is open source and free software, licensed under a Modified LGPL license. The toolkit has been implemented using the Free Pascal compiler, meaning it is written in the Object Pascal language.
Geany is a free and open-source lightweight GUI text editor using Scintilla and GTK, including basic IDE features. It is designed to have short load times, with limited dependency on separate packages or external libraries on Linux. It has been ported to a wide range of operating systems, such as BSD, Linux, macOS, Solaris and Windows. The Windows port lacks an embedded terminal window; also missing from the Windows version are the external development tools present under Unix, unless installed separately by the user. Among the supported programming languages and markup languages are C, C++, C#, Java, JavaScript, PHP, HTML, LaTeX, CSS, Python, Perl, Ruby, Pascal, Haskell, Erlang, Vala and many others.
mpv is free and open-source media player software based on MPlayer, mplayer2 and FFmpeg. It runs on several operating systems, including Unix-like operating systems and Microsoft Windows, along with having an Android port called mpv-android. It is cross-platform, running on ARM, PowerPC, x86/IA-32, x86-64, and MIPS architecture.
The Free Pascal Runtime Library, abbreviated RTL, is Free Pascal's runtime library.
The Free Component Library, abbreviated FCL, is a software component library for Free Pascal.
Widgetsets support platform-sensitive development with the Lazarus IDE system. They act as adapter libraries that provide an interface between a platform-inpedentent sourcecode written in Free Pascal and platform-specific system functions. Thus they allow for development of platform-native software without requiring to provide specific source code for different target platforms.
