QML
QML (Qt Modeling Language) is a user interface markup language. It is a declarative language (similar to CSS and JSON) for designing user interface–centric applications. Inline JavaScript code handles imperative aspects. It is associated with Qt Quick, the UI creation kit originally developed by Nokia within the Qt framework. Qt Quick is used for mobile applications where touch input, fluid animations and user experience are crucial. QML is also used with Qt3D to describe a 3D scene and a "frame graph" rendering methodology. A QML document describes a hierarchical object tree. QML modules shipped with Qt include primitive graphical building blocks (e.g., Rectangle, Image), modeling components (e.g., FolderListModel, XmlListModel), behavioral components (e.g., TapHandler, DragHandler, State, Transition, Animation), and more complex controls (e.g., Button, Slider, Drawer, Menu). These elements can be combined to build components ranging in complexity from simple buttons and sl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qt (framework)
Qt (pronounced "cute") 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. Qt is currently being developed by The Qt Company, a publicly listed company, and the Qt Project under open-source governance, involving individual developers and organizations working to advance Qt. Qt is available under both commercial licenses and open-source GPL 2.0, GPL 3.0, and LGPL 3.0 licenses. Purposes and abilities Qt is used for developing graphical user interfaces (GUIs) and multi-platform applications that run on all major desktop platforms and most mobile or embedded platforms. Most GUI programs created with Qt have a native-looking interface, in which case Qt is classified as a ''widget toolkit''. No ...

Unity (user Interface)
Unity is a graphical shell for the GNOME desktop environment originally developed by Canonical Ltd. for its Ubuntu operating system. It debuted in 2010 in the netbook edition of Ubuntu 10.10. Since 2017, its development was taken over by the Unity7 Maintainers (Unity7) and UBports (Lomiri, formerly known as Unity8). Unity7 is the default desktop environment in Ubuntu Unity, an official flavor of Ubuntu since 2022. Ubuntu Unity and Unity7 Maintainers have started working on the successor of Unity7, UnityX. It was part of the Ayatana project, an initiative with the stated intention of improving the user experience within Ubuntu. It was initially designed to make more efficient use of space given the limited screen size of netbooks, including, for example, a vertical application switcher called the ''launcher'', and a space-saving horizontal multipurpose ''top menu bar''. Unlike GNOME, KDE Plasma, Xfce, or LXDE, Unity is not a collection of applications. It is designed to u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qt Quick
Qt Quick is a free software application framework developed and maintained by the Qt Project within the Qt framework. It provides a way of building custom, highly dynamic graphical user interfaces with fluid transitions and effects, which are becoming more common especially in mobile devices. Qt Quick includes a declarative scripting language called QML. Qt Declarative is a runtime interpreter that reads the ''Qt declarative user interface definition'', QML data, and displays the UI that it describes. The QML syntax allows using JavaScript to provide the logic, and it is often used for this purpose. It is not the only way, however: logic can be written with native code as well. Qt Quick and QML are officially supported in Qt 4.7 (with Qt Creator 2.1), and it is a commercial option in mobile applications when Qt 4.7 is available for deployment in Symbian and Maemo and MeeGo devices. It was also the native language of Ubuntu Touch. Version history See also * Clutter, a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KDE Plasma 4
KDE Plasma 4 was the fourth generation of the KDE workspace environments. It consisted of three workspaces, each targeting a certain platform: ''Plasma Desktop'' for traditional desktop PCs and Notebook (computer), notebooks, ''Plasma Netbook'' for netbooks, and ''Plasma Active'' for tablet computer, tablet PCs and similar devices. KDE Plasma 4 was released as part of KDE Software Compilation 4 and replaced Kicker (KDE), Kicker, KDesktop, and SuperKaramba, which formed the Desktop in earlier KDE releases. They are bundled as the default environment with a number of free software operating systems, such as Chakra (operating system), Chakra, Kubuntu, Mageia (DVD version), openSUSE, or TrueOS. With the release of KDE SC 4.11 on 14 August 2013, KDE Plasma 4 was placed into a feature freeze and turned into a long-term stable package until August 2015. On 15 July 2014 KDE Plasma 4's successor, KDE Plasma 5, was released. Features Plasma features ''containments'', which are essential ...

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 on the sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plasma-framework
KDE Frameworks is a collection of libraries and software frameworks readily available to any Qt-based software stacks or applications on multiple operating systems. Featuring frequently needed functionality solutions like hardware integration, file format support, additional graphical control elements, plotting functions, and spell checking, the collection serves as technological foundation for KDE Plasma 5 and KDE Gear distributed under the GNU Lesser General Public License (LGPL). Overview Current KDE Frameworks are based on Qt 5, which enables a more widespread use of QML, a simpler JavaScript-based declarative programming language, for the design of user interfaces. The graphics rendering engine used by QML allows for more fluid user interfaces across different devices. Since the split of the KDE Software Compilation into KDE Frameworks 5, KDE Plasma 5 and KDE Applications, each sub-project can pick its own development pace. KDE Frameworks are released on a monthly basis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
User Interface Markup Language
A user interface markup language is a markup language that renders and describes graphical user interfaces and controls. Many of these markup languages are dialects of XML and are dependent upon a pre-existing scripting language engine, usually a JavaScript engine, for rendering of controls and extra scriptability. The concept of the user interface markup languages is primarily based upon the desire to prevent the " re-invention of the wheel" in the design, development and function of a user interface; such re-invention comes in the form of coding a script for the entire user interface. The typical user interface markup language solidifies often re-used program or script code in the form of markup, making it easier to focus upon design of a user interface in an understandable dialect as opposed to focus on function. User interface markup languages, like most markup and programming languages, rely upon sub-application runtimes to interpret and render the markup code as program c ...

Simple Desktop Display Manager
Simple Desktop Display Manager (SDDM) is a display manager (a graphical login program and session manager) for the X11 and Wayland windowing systems. SDDM was written from scratch in C++11 and supports theming via QML. SDDM is free and open-source software subject to the terms of the GNU General Public License version 2 or later. Adoption In 2013, Fedora KDE members decided to default to SDDM in Fedora 21. KDE chose SDDM to be the successor of the KDE Display Manager for KDE Plasma 5. The LXQt developers recommend SDDM as a display manager.

Sailfish OS
Sailfish OS is a Linux-based operating system based on free software, and open source projects such as Mer as well as including a closed source UI. The project is being developed by the Finnish company Jolla. The OS first shipped with the original Jolla Phone in 2013 (its sale stopped in 2016, but it was supplied with software updates until the end of 2020), then the Jolla Tablet in 2015 and from other vendors licensing the OS. The OS is ported by community enthusiasts to third-party mobile devices including smartphones and tablet computers. Sailfish OS can be used for many kinds of devices. History and development The OS is an evolved continuation of the Linux MeeGo OS previously developed by alliance of Nokia and Intel which itself relies on combined Maemo and Moblin. The MeeGo legacy is contained in the Mer core in about 80% of its code; the Mer name thus expands to MEego Reconstructed. This base is extended by Jolla with a custom user interface and default applicatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MeeGo
MeeGo is a discontinued Linux distribution hosted by the Linux Foundation, using source code from the operating systems Moblin (produced by Intel) and Maemo (produced by Nokia). Primarily targeted at mobile devices and information appliances in the consumer electronics market, MeeGo was designed to act as an operating system for hardware platforms such as netbooks, entry-level desktops, nettops, tablet computers, mobile computing and communications devices, in-vehicle infotainment devices, SmartTV / ConnectedTV, IPTV-boxes, smart phones, and other embedded systems. Nokia wanted to make MeeGo its primary smartphone operating system in 2010, but after a change in direction it was stopped in February 2011, leaving Intel alone in the project. The Linux Foundation canceled MeeGo in September 2011 in favor of Tizen, which Intel then joined in collaboration with Samsung. A community-driven successor called Mer was formed that year. A Finnish start-up, Jolla, picked up Mer to develop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ring (programming Language)
Ring is a dynamically typed, general-purpose programming language. It can be embedded in C/C++ projects, extended using C/C++ code and/or used as a standalone language. The supported programming paradigms are imperative, procedural, object-oriented, functional, meta, declarative using nested structures, and natural programming.
