Abstract

A method of and system for generating a user-display interface which displays and manages multiple child windows anywhere on a display screen. An application is executed to create a server and to create a context manager, the context manager for monitoring current context. The application also creates and initializes a frame window, the frame window including at least an application menu and being commanded by the server so that a header block of the frame window may be selectively displayed by the operating system as a visible window on a display screen. The frame window is executed to create zero or more child nodes in response to requests to open child nodes from the application, each of the child nodes having a context type associated therewith and zero or more of the child nodes being context sensitive, the context type being monitored by the context manager, each of the child nodes being commanded by the frame to be selectively displayed by the operating system as a visible window on the display screen. Items of the application menu may be altered as a function of the context type currently being monitored by the context manager.
