Method and apparatus for selecting button function and retaining selected optics on a display

摘要

The invention is an object-oriented graphic interface for use in computer controlled display systems. A central processing unit (CPU) is provided and is coupled to a display for displaying graphic and other data. The CPU is further coupled to a cursor control device which permits a user to selectively position a cursor at a desired location on the display, and signal the CPU of selections in accordance with the teachings of the present invention. Buttons are generated by the CPU and displayed which correspond to either a single function to be executed by the CPU, or a button stack which has associated therewith a plurality of functions disposed on a menu. The menu includes a plurality of buttons and/or button stacks. The menu also includes a first icon, which presently is in the form of a push pin. The placement of the cursor over the push pin and releasing the first switch on the cursor control results in the CPU converting the menu into a window. The CPU then retains this window on the display regardless of other display operations performed. The window may be dismissed, at any time, by placing the cursor over a push pin provided on the border of the window and momentarily depressing and releasing the first switch on the cursor control device. In addition, if the user once again places the cursor over the push pin and momentarily depresses and releases the first switch on the cursor control device, then the window will be dismissed after the execution of any of the button or button stacks disposed within the window.
