DISPLAYING THE DESKTOP UPON DEVICE OPEN

1 . A computer readable medium, having stored thereon, computer-executable instructions executable by a processor, the computer-executable instructions causing the processor to execute a method for managing a window stack for a device, the computer-executable instructions comprising:

instructions to receive an orientation change, wherein the orientation change causes the device to transition from a closed state to an open state, wherein, in the closed state, a first display is active and, in the open state, both the first display and a second display are active;

instructions to determine if a desktop should be displayed on the second display; and

after determining the desktop should be displayed on the second display, instructions to display the desktop on the second display and a first window on the first display.

2 . The computer readable medium as defined in claim 1 , wherein the window stack is a logical arrangement of active and inactive windows for the multi-screen device.

3 . The computer readable medium as defined in claim 2 , wherein the window stack provides a representation of windows or display objects to the user.

4 . The computer readable medium as defined in claim 3 , wherein the desktop is a display object.

5 . The computer readable medium as defined in claim 4 , wherein the desktop is displayed across a composite display, wherein the composite display occupies substantially all of the at least the two or more touch sensitive displays, and wherein the first display and second display are portions of the composited display.

6 . The computer readable medium as defined in claim 5 , further comprising instructions to modify a logical data structure associated with the desktop.

7 . The computer readable medium as defined in claim 6 , wherein the logical data structure comprises one or more of:

a window identifier adapted to identify the desktop in relation to other windows in the window stack;

a window stack position identifier adapted to identify the position in the window stack for the desktop; and

a display identifier adapted to identify the composite display of the multi-screen device, which the desktop is associated.

8 . The computer readable medium as defined in claim 6 , wherein a first display of the multi-screen device is associated with a first portion of the window stack and a second display of the multi-screen device is associated with a second portion of the window stack.

9 . The computer readable medium as defined in claim 8 , wherein the logic data structure further comprises a window stack identifier adapted to identify both the first portion and second portion of which the desktop is associated.

10 . A device comprising:

at least two displays;

a memory;

a processor in communication with the memory and each of the at least two displays, the processor operable to:

provide a composite display, wherein the composite display comprises one touch sensitive displays in a closed state;

receive an orientation change in the multi-screen device, wherein the orientation change causes the multi-screen device to transition from a closed state to an open state, wherein, in the open state, the composite display comprises a first portion associated with the first touch sensitive display and a second portion associated with a second touch sensitive display;

expand a desktop to cover the composite display;

determine a first window is displayed in a first portion of the composite display and the desktop is displayed in a second portion of the composite display; and

display the desktop on the second touch sensitive display and the first window on the first touch sensitive display.

11 . The device as defined in claim 10 , wherein the desktop is altered upon the transition to the open state.

12 . The device as defined in claim 11 , further comprising altering a logic data structure associated with the desktop.

13 . The device as defined in claim 12 , wherein the desktop is associated with both of the two touch sensitive displays.

14 . The device as defined in claim 13 , wherein the logic data structure comprises one or more of:

a window identifier adapted to identify the desktop in relation to other windows in the window stack;

a window stack position identifier adapted to identify the top position in the window stack for the desktop in at least the second portion of the composited display; and

at least two display identifiers adapted to identify each of the at least two touch sensitive displays of the multi-screen device which the desktop is associated.

15 . The device as defined in claim 14 , wherein the desktop is at the bottom of the opened at a bottom of a window stack and is displayed because no window covers the desktop in at least a portion of the composite display.

16 . The device as defined in claim 15 , wherein the first window covers at least a portion of the desktop.

17 . A method for presenting a display for a multi-screen device, the method comprising:

providing a composite display that spans at least a portion of a first touch sensitive display when the multi-screen device is in a closed state;

displaying a first window at a top of a window stack when the device is in the closed state;

receiving an orientation change for the multi-screen device, wherein the orientation change is a transition from the closed state to an open state;

changing the composite display to span at least a portion of the first touch sensitive display and a second touch sensitive display of the multi-screen device, wherein a first portion of the composite display is associated with the first touch sensitive display and a second portion of the composite display is associated with the second touch sensitive display;

determining that a desktop is associated with the composite display;

modifying the desktop to expand over the composite display;

determining the first window is at the top of the window stack in the first portion of the composite display;

determining the desktop is at the top of the window stack in the second portion of the composite display;

displaying the first window on the first touch sensitive display; and

displaying the desktop on the second touch sensitive display.

18 . The method defined in claim 17 , wherein the desktop is at a bottom of the window stack.

19 . The method defined in claim 18 , wherein the first window is a last window in a window stack comprising two or more windows.

20 . The method defined in claim 19 , wherein the first touch sensitive display is part of a primary screen.
