The ProxyGen main window provides a tree view to navigate through Open Client objects as you define them. The root (top) object in the tree view always is the AppObject definition for the Open Client interface (for example, OrderInfo ). Any child nodes in the tree view (for example, Customer ) are SubAppObjects associated with this AppObject. Depending on your selection in the tree view, ProxyGen displays tab folders that show the definition for the selected object. You complete the Open Client interface definition by entering information in the tab folders and using the options available from the menu bar and toolbar.
To edit an existing Open Client interface, open the project file (with extension .xpxg in OpenEdge Releases 10 or later, or .pxg in Version 9) containing a given Open Client interface. To open this file, use the ProxyGen File menu or open the project file directly in Windows Explorer. This project file serves as a repository for a single Open Client interface definition to generate all Open Client interfaces, including .NET, Java, and SOAP Web services.
