A development environment and method is provided in which a first computer system is used to develop an application for execution in a second computer system--such as a pen-based computer--having a graphical user interface. The first computer system also has a graphical user interface that can display (1) a palette containing lists and/or buttons of 'components' representing graphical interface elements such as slide bars, dialog boxes, buttons, check boxes, icons, menus, etc., (2) a layout window corresponding a display screen of the second computer and containing 'views' of selected palette components and (3) a browser allowing the views to be edited graphically. To develop an application, the user creates views on the layout window by (1) selecting a component from the palette and (2) drawing a border for the view in the layout window. Each view so created represents a 'template' which is a frame object having a plurality of 'slots' which may be edited in a slot editor area of the browser. Some views in the layout window may be 'linked views' which point to sublayout windows containing a plurality of other views. Still further, a system is provided that allows the creation of user defined proto templates containing an arrangement of views defined by the user. The user-defined proto templates can be used to create views in the layout window as described above.

Method of creating packages for a pointer-based computer system

A scanning method for receiving a signal in a frequency hopped communication system that transmits a packet having N segments that are encoded with an error correction code that allows recovery of a packet even if e segments are erasures. A receiving station continuously scans the first p (1.ltoreq.p.ltoreq.e+1) channels, testing each channel for the existence of a transmission. If detected, a segment is received, and then the receiving station sequences through the remaining channels, receiving the segments if possible, and then applying error correction to the complete transmission. This technique of scanning the first several channels, receiving the first unimpaired segment, and thereby gaining the ability to recover all unimpaired segments enables the full theoretical power of a coded, slow frequency hopped system to be realized.
