Method and apparatus for presenting a window in a system having two operating system environments

An apparatus comprising:

• a central processing unit (CPU);
• a first graphical user interface (first GUI);
• and
• a second GUI, wherein the CPU
• executes a first operating system environment (first OSE) in a native mode on the CPU of the apparatus, wherein the apparatus comprises the first GUI, and wherein the first OSE generates graphical data for a first OSE window, and wherein the first OSE window can be used on the first GUI for interfacing with the first OSE,
• executes a second operating system environment (second OSE) in a native mode on the CPU of the apparatus, wherein the second OSE generates a desktop that is displayed on a second GUI, and renders on the GUI desktop a second window that comprises the first OSE window, wherein the rendering comprises communicating by the second OSE relevant events to the first OSE and modifying by the first OSE the graphical data of the first OSE window in response to one or more of the relevant events.

A tangible computer readable medium that stores instructions that are executable by a processor for performing a method of rendering a window that comprises:

• executing a first operating system environment (first OSE) in a native mode on a central processing unit (CPU) of a mobile device, wherein the mobile device comprises a first graphical user interface (GUI), and wherein the first OSE generates graphical data for a first OSE window, and wherein the first OSE window can be used on the first GUI for interfacing with the first OSE;
• executing a second operating system environment (second OSE) in a native mode on the CPU of the mobile device, wherein the second OSE generates a desktop that is displayed on a second GUI;
• and
• rendering on the GUI desktop a second window that comprises the first OSE window (this second OSE window is hereafter referred to as the WIW), wherein the rendering comprises
• communicating by the second OSE relevant events to the first OSE and
• modifying by the first OSE the graphical data of the first OSE window in response to one or more of the relevant events.
