wwWidgets is a professional set of useful widgets for Qt 4. It consists of several different widgets that are either enhanced versions of widgets bundled with Qt or completely new ones that implement functionality not available in Qt including custom multipage container widgets that can hold other widgets.
The classes follow all guidelines for building new widgets. Thanks to that they can be used with different widget styles (like Plastique or WindowsXP) and they are easily stylable using Qt style sheets allowing a perfect blend with the rest of your application.
All widgets can be used directly from within Qt Designer thanks to the widget plugin accompanying the library. The plugin makes it possible to place wwWidgets on forms and edit their properties and contents just like for default widgets â€“ using the property browser and dedicated property editors for complex properties like sets of colors.
wwWidgets are well documented, after installing the package, the reference is available from within Qt Assistant. The documentation looks like the one available for default Qt classes so it integrates well with it â€“ you can browse and search the documentation and all wwWidgets component symbols can be found in the index.
wwWidgets is available under dual licence â€“ GPL for Open Source development and Commercial licence for other users.
