JComponentPack is a GUI library based on Java Swing, a collection of visual JavaBeans. It is built on the MVC architecture of Swing and is a 100% pure Java library. It includes over 20 components not found in Swing, such as an EXCEL-style Java spreadsheet component, a Java table component for reading database tables, a calendar component, a list component similar to an explorer, a wizard framework, and more. These JavaBeans can be directly dragged and dropped into your graphical user interface, improving your work efficiency and accelerating your project development process.
