OpenSwing is an open-source suite of advanced graphics components based on Swing toolkit: these components are more sophisticated of those provided with Swing and can be manipulated directly inside the UI designer of the IDE.
It is also a framework that provides data binding mechanism between components and data model, based on the MVC paradigm. Data model is based on Java Beans (POJOs) and it is supported in all OpenSwing components, such as grid control, tree control or generic controls container.
OpenSwing provides a complete solution (a framework and advanced swing components with data binding capabilities) to quickly and easily develop rich-client applications.
It is possibile to apply this framework to develop java Desktop Applications or Rich Internet Applications (three tiered applications based on Swing front-end + HTTP + java servlet + database) or Distributed Applications (three tiered applications based on Swing front-end + RMI + java session bean stateless + database).
OpenSwing includes a collection of classes that can be used:
* to create the application front-end, through a collection of advanced graphics controls, comparable to those provided by traditional RAD development environments like Visual Basic or Delphi.
Graphics controls include more than 30 widgets: label control, multi-line label control, text field, text formatted field, multi-line text field, numeric field, currency field, calendar, grid, nested grids, grid with nested generic components, properties grid, pivot table, tree, check-box tree, tree combined with a grid, lookup, multi code lookup, lookups with auto-completition, gantt diagram, buttons with image, combo-box, combo-box multi-column, radio button, check-box, list, check-box list, list multi-column, wizard panel, image panel, splash screen, dialog windows, tip of the day frame, progress bar/panel/dialog, licence agreement panel, alert window, iconifable window, "outlook like" panes, link button.
Grid usage is especially sophisticated: it allows columns or rows locking, data pagination, columns filtering and sorting, persistent storage of grid "state" (sorting/filtering conditions, columns position/width/visibility), permissions at column level (editability/visibility/mandatory state defined at column level), data import/export and the grid model is based on a list of POJOs as for a tree component and as for a panel of graphics controls whose data model is based on a POJO. POJO support is extended to the entire set of graphical components that compose the GUI.
Graphics controls are compliance with Java Beans specifications, so they can be used in the UI designer of an IDE, such as JBuilder, JDeveloper, NetBeans, Eclipse in order to create windows by drawing components on them using UI designer, likewise with other non java RAD environment.
Building grids is expecially easy: a grid can be graphically composed by using the UI designer of
- improved export to PDF/RTF formats: now it is possible to include a more recent version of iText 2.1.7 (for java 1.5/1.6 only);
changed org.openswing.swing.export.java classses, in order to support both old iText version (for java 1.4) and newer version.
