KDE Plasma Active is a user interface for all types of tablets, smartphones, and touch computing devices, such as settop boxes, smart TVs, home automation, and in-vehicle infotainment. It is a joint project by the KDE community, basysKom, and open-slx. Its goals are a fast embedded UX platform with minimal memory requirements, customizable and modular to support different form factors, and an interface which adapts as users change activities.
ArtTk is a graphic library based on Java/Swing offering an open development toolkit intended specifically for scientific and technical applications. It provides a set of widgets and functional modules a set of support modules (helpers) permitting dynamic definition of menus and tool bars from simple XML configured files, and supporting tooltips, icons, action commands, etc.; a very adaptable generic desktop, facilitating the assembly of Swing components in a specialized GUI; an extended Grid layout to simplify the development of advanced scientific applications; and a set of scientific and technical widgets, such as a dynamic memory footprint monitor, simple key-values based fields editors, a generic color gradient editor, etc.
Qore Qt4 module allows GUIs to be implemented in the Qore programming language. This module is based on libsmoke and provides access to the entire Qt4 API exported by libsmoke. The module supports hard typing, function and method overloading, and all Qt4 enums and constants to provide relatively direct access to the native Qt4 API in the Qore language. A uic-qore program is included so that Qt4 designer is usable for making GUI prototypes as well.
JHeatChart is a one class Java API for generating heat map charts that was created because very few charting APIs seem to contain the facility to create heat maps. It is not a full featured charting API and cannot be used to other charts. The generated charts are created as Java Image objects, which can be incorporated into a GUI or saved to a file.
JCrocus is a GUI that allows representing the network topology definition of microwave cavity filters based on the coupling matrix approach as well as simulating and plotting its frequency response. It is a software tool for electromagnetic engineers; it is also a pedagogic instrument for professors and students in electromagnetic engineering to teach and learn the theory behind the microwave cavity filters.
The primary aim of the Gtk+2 panel project is to provide a panel that reuses whatever is available (if it is not overkill) in the obvious way, such as subclassing GtkWidget instead of implementing applets, or by using a GtkBuilder file instead of defining a new format to customize the panel. This approach gives some additional advantages for free: you can use common tools in uncommon ways. Above all, you can use Glade to design your own panel. All the dependencies apart from GTK+ are (and hopefully will be) optional.
Kalpa.Cloud is a toolkit for developing SaaS applications. It consists of a Universal Cross-platform Client and a Qt-based library. It allows the developer to develop Rich Internet Applications with GUI using the Qt programming style for the server and to implement it as easily as possible.
