Method and system of accessing display window memory

摘要

A method and system of accessing display window memory. At least some of the illustrative embodiments are methods comprising abstracting display window memory by way of a first software object, accessing the display window memory by routines of a graphics library executed on a first processor (the accessing by way of the first software object), and displaying a window on a display screen, contents of the window selected at least in part by the routines of the graphics library.

主权项

1. A method comprising:
in a display window memory, storing contents of first and second windows; on a display device, displaying the contents of the first and second windows from the display window memory; with a first processor that executes Java bytecodes directly: creating a Java software object for abstracting the display window memory; executing a first application program for controlling the contents of the first window through the Java software object, at least in part by calling routines of a Java graphics library for performing operations in the first window; and executing a first window manager program; and with a second processor: executing a second application program for controlling the contents of the second window; and executing a second window manager program; wherein executing the first window manager program includes executing the first window manager program for, through a Java native interface call, informing the second window manager program about creation, movement and re-sizing of the first window; and wherein executing the second window manager program includes executing the second window manager program for: controlling placement of the second window on the display device; controlling whether the first window is located in a foreground on the display device; and controlling placement of the first window on the display device, in response to being informed by the first window manager program through the Java native interface call.
