Qt is cross-platform software for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed.
In computing, cross-platform software is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms.
wxWidgets is a widget toolkit and tools library for creating graphical user interfaces (GUIs) for cross-platform applications. wxWidgets enables a program's GUI code to compile and run on several computer platforms with minimal or no code changes. A wide choice of compilers and other tools to use with wxWidgets facilitates development of sophisticated applications. wxWidgets supports a comprehensive range of popular operating systems and graphical libraries, both proprietary and free, and is widely deployed in prominent organizations.
The SWORD Project is the CrossWire Bible Society's free software project. Its purpose is to create cross-platform open-source tools—covered by the GNU General Public License—that allow programmers and Bible societies to write new Bible software more quickly and easily.
Kile is a TeX/LaTeX editor to edit TeX/LaTeX source code. It runs on Unix-like systems including Mac OS X and Linux, as well as Microsoft Windows via the KDE on Windows initiative, with the Qt and KDE libraries installed.
The Geometer's Sketchpad is a commercial interactive geometry software program for exploring Euclidean geometry, algebra, calculus, and other areas of mathematics. It was created as part of the NSF-funded Visual Geometry Project led by Eugene Klotz and Doris Schattschneider from 1986 to 1991 at Swarthmore College. Nicholas Jackiw, a student at the time, was the original designer and programmer of the software, and inventor of its trademarked "Dynamic Geometry" approach; he later moved to Key Curriculum Press, KCP Technologies, and McGraw-Hill Education to continue ongoing design and implementation of the software over multiple major releases and hardware platforms. Present versions run Microsoft Windows and Mac OS 8. It also runs on Linux under Wine with a few bugs. There was also a version developed for the TI-89 and TI-92 series of Calculators. In June 2019 McGraw-Hill announced they will no longer sell new licenses. Nonetheless, a new (2021) 64-bit version of Mac Sketchpad that is compatible with the new Apple M1 silicon chips is available as part of an ongoing beta test.
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.
Transmission is a BitTorrent client which features a variety of user interfaces on top of a cross-platform back-end. Transmission is free software licensed under the terms of the GNU General Public License, with parts under the MIT License.
SageMath is a computer algebra system (CAS) with features covering many aspects of mathematics, including algebra, combinatorics, graph theory, numerical analysis, number theory, calculus and statistics.
KeePassX started as a Linux port of KeePass, which was at that time an open-source but Windows-only password manager. Both are now cross platform, with KeePassX using Qt libraries and recent versions of KeePass using .NET / Mono. It is built using version 5 of the Qt toolkit, making it a multi-platform application, which can be run on Linux, Windows, and macOS.
PySide is a Python binding of the cross-platform GUI toolkit Qt developed by The Qt Company, as part of the Qt for Python project. It is one of the alternatives to the standard library package Tkinter. Like Qt, PySide is free software. PySide supports Linux/X11, macOS, and Microsoft Windows.
KVIrc is a graphical IRC client for Linux, Unix, Mac OS and Windows. The name is an acronym of K Visual IRC in which the K stands for a dependency to KDE, which became optional from version 2.0.0. The software is based on the Qt framework and its code is released under a modified GNU General Public License.
PPSSPP is a free and open-source PSP emulator for Windows, macOS, Linux, iOS, Android, Nintendo WiiU, Nintendo Switch, BlackBerry 10, MeeGo, Pandora, Xbox Series X, Xbox Series S, and Symbian with an increased focus on speed and portability. It was first released to the public on November 1, 2012, licensed under the GNU GPLv2 or later. The PPSSPP project was created by Henrik Rydgård, one of the co-founders of the Dolphin emulator.
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 Lazarus Component Library, abbreviated LCL is a visual software component library for the Lazarus IDE.
