Abstract

An application can be formed by using a plurality of program modules each having an associated display window. These modules could communicate with each other to perform desired activities. A user organizes the windows associated with these modules in a desired spatial arrangement. Various parent-child relationships among the display windows are used to place constraints on the appearance of the windows. When the program modules are executed, they communicate with each other to perform desired activities while the associated windows maintain a predetermined graphic relationship. Consequently, the application gives the appearance that it contains tightly coupled program modules instead of modules that can be selected and arranged easily by a user with little programming experience.

Dependent claims

A method for a user to design a graphic-user-interface-based application executing under a windows-based environment, said environment providing a parent-child relationship between windows in which a child window is bounded by a parent window and moves together with said parent window, comprising the steps of:

providing a plurality of program modules, each of said program modules associating with a display window and capable of communicating with other program modules;
selecting at least a first and a second one of said plurality of program modules, said first program module being associated with a first display window and said second program module being associated with a second display window, said first program module controlling operations of said second program module by sending commands to said second program module;
selecting a third program module from said plurality of program modules, said third program module being associated with a third display window;
positioning, by said user, said first and said second display windows in a position inside said third display window;
changing said first and said second display windows to be children of said third display window so that said first and said second display windows are bounded by and moves with said third display window;
said first program module being associated with a first parameter file;
said second program module being associated with a second parameter file;
said first program module containing means for sending a first command to said second parameter file;
said second program module containing means for sending a second command to said first parameter file;
said first program module containing means for executing said second command in said first parameter file without returning result of execution to said second program module;
and
said second program module containing means for executing said first command in said second parameter file without returning result of execution to said first program module.

A method for a user to design a graphic-user-interface-based application executing under a windows-based environment, said environment providing a parent-child relationship between windows in which a child window is bounded by a parent window and has a definite position relative to said parent window, comprising the steps of:

providing a plurality of program modules, each of said program modules can be displayed as either a display window or an edit window, each of said program modules having a parameter file and capable of communicating with other program modules;
selecting a first one of said plurality of program modules, said first program module being displayed as a first edit window and said first edit window containing a first icon;
selecting a second program module from said plurality of program modules, said second program module being displayed as a second display window;
clicking, by said user, on said icon of said first edit window for indicating a desire to change said first edit window into a child window;
positioning said first edit window inside said second display window;
changing said first edit window into a first display window;
and
changing said first display window to be a child of said second display window.
