Troll Tech
Qt Group Plc (pronounced "cute"; formerly known as Trolltech, Qt Company, Qt Development Frameworks and Qt Software) is a global software company headquartered in Espoo, Finland. It was formed following the acquisition of Qt by Digia, but was later spun off into a separate, publicly traded company. The company oversees the development of the Qt framework alongside the Qt Project, and provides tools for UI design, software development, quality assurance and testing, as well as expert consulting services. History Trolltech 1994–2007 Trolltech was founded by Eirik Chambe-Eng and Haavard Nord on 4 March 1994. They started writing Qt in 1991, and since then Qt has steadily expanded and improved. In 2002 Trolltech introduced Qtopia which is based on Qt. Qtopia is an application platform for Linux-based devices such as mobile phones, portable media players, and home media. It is also used in many non-consumer products such as medical instruments and industrial devices. Qtopia P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qt Project
The Qt Project is an open collaboration effort to coordinate the development of the Qt software framework. Initially founded by Nokia in 2011, the project is now led by The Qt Company. History Haavard Nord and Eirik Chambe-Eng (the original developers of Qt and the CEO and President, respectively, of Trolltech) began development of "Qt" in 1991, three years before the company was incorporated as Quasar Technologies, then changed the name to Troll Tech and then to Trolltech. Until version 1.45 the source code of Qt was released under the ''Qt Free Edition License''. This was viewed as not compliant with the open source principle by the Open Source Initiative and the free software definition by Free Software Foundation because, while the source was available, it did not allow the redistribution of modified versions. Controversy arose around 1998 when it became clear that KDE's K Desktop Environment was going to become one of the leading desktop environments for Linux. As i ...

Smartphone
A smartphone is a portable computer device that combines mobile telephone and computing functions into one unit. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software, internet (including web browsing over mobile broadband), and multimedia functionality (including music, video, cameras, and gaming), alongside core phone functions such as voice calls and text messaging. Smartphones typically contain a number of metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, include various sensors that can be leveraged by pre-included and third-party software (such as a magnetometer, proximity sensors, barometer, gyroscope, accelerometer and more), and support wireless communications protocols (such as Bluetooth, Wi-Fi, or satellite navigation). Early smartphones were marketed primarily towards the enterprise market, attempting to bridge the functionality of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KDE Plasma 5
KDE Plasma 5 is the fifth and current generation of the graphical workspaces environment created by KDE primarily for Linux systems. KDE Plasma 5 is the successor of KDE Plasma 4 and was first released on 15 July 2014. It includes a new default theme, known as "Breeze", as well as increased convergence across different devices. The graphical interface was fully migrated to QML, which uses OpenGL for hardware acceleration, which resulted in better performance and reduced power consumption. Plasma Mobile is a Plasma 5 variant for Linux-based smartphones. Overview Software architecture KDE Plasma 5 is built using Qt 5 and KDE Frameworks 5, predominantly plasma-framework. It improves support for HiDPI displays and ships a convergable graphical shell, which can adjust itself according to the device in use. 5.0 also includes a new default theme, dubbed Breeze. Qt 5's QtQuick 2 uses a hardware-accelerated OpenGL( ES) scene graph (canvas) to compose and render graphics o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-platform
In computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent 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. For example, a cross-platform application may run on Microsoft Windows, Linux, and macOS. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, Kivy, Qt, Flutter, NativeScript, Xamarin, Phonegap, Ionic, and React Native. Platforms ''Platform'' can refer to the type of processor (CPU) or other hardware on which an operating system (OS) or applicatio ...

Free Software
Free software or libre software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program.Selling Free Software (gnu.org) Computer programs are deemed "free" if they give end-users (not just the developer) ultimate control over the software and, subsequently, over their devices. The right to study and modify a computer program entails that source code< ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PyQt

Language Binding
In programming and software design, binding is an application programming interface (API) that provides glue code specifically made to allow a programming language to use a foreign library or operating system service (one that is not native to that language). Characteristics Binding generally refers to a mapping of one thing to another. In the context of software libraries, bindings are wrapper libraries that bridge two programming languages, so that a library written for one language can be used in another language. Many software libraries are written in system programming languages such as C or C++. To use such libraries from another language, usually of higher-level, such as Java, Common Lisp, Scheme, Python, or Lua, a binding to the library must be created in that language, possibly requiring recompiling the language's code, depending on the amount of modification needed. However, most languages offer a foreign function interface, such as Python's and OCaml's ctypes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 reduced its influence.
