Abstract

A method for swapping display contents between a first and a second screen. The first screen is a primary screen. A window is displayed on one of the first and the second screen. The method includes: calculating a window movement distance according to a relative position between the first and the second screen; performing swapping to set the second screen as the primary screen; obtaining a coordinate of the window after swapping; obtaining a first coordinate by adding the window movement distance to the coordinate of the window after swapping if the window is located in the first screen before swapping; obtaining a second coordinate by subtracting the window movement distance from the coordinate of the window after swapping if the window is located in the second screen before swapping; moving the window from one of the first and the second screen to the other.

Claims

1. A method for swapping display contents between a first screen and a second screen, wherein the first screen is a primary screen, a window is displayed on one of the first screen and the second screen, the method comprising:

(a) calculating a window movement distance according to a relative position between the first screen and the second screen;

(b) performing swapping to set the second screen as the primary screen;

(c) obtaining a coordinate of the window after swapping;

(d) obtaining a first coordinate by adding the window movement distance to the coordinate of the window after swapping if the window is located in the first screen before swapping;

(e) obtaining a second coordinate by subtracting the window movement distance from the coordinate of the window after swapping if the window is located in the second screen before swapping; and

(f) moving the window from one of the first screen and the second screen to the other according to the first coordinate or the second coordinate.

2. The method according to claim 1, wherein, the step (a) further comprises:

identifying respective resolution of the first screen and the second screen.

3. The method according to claim 1, the method further comprises:

recording an original display sequence of all windows.

4. The method according to claim 1, wherein, further comprises:

if the window is a maximized window or a minimized window, then;

restoring the window as a normal viewable window;

moving the window; and

restoring the window back as the maximized window or the minimized window.

5. The method according to claim 1, wherein, the window is a viewable window.

6. A method for swapping display contents between multiple screens, the method comprising:

(a) receiving a swapping instruction;

(b) identifying a relative position between the screens and respective resolution of each screen;

(c) recording an original display sequence of viewable windows display;

(d) moving all viewable windows displayed on each screen; and

(e) setting the moved viewable windows according to the recorded original display sequence.

7. The method according to claim 6, wherein, the step (d) comprises:

(d1) calculating a window movement distance according to the relative position;

(d2) performing swapping;

(d3) obtaining a coordinate of the viewable window after swapping;

(d4) obtaining a first coordinate by adding the window movement distance to the coordinate of the viewable window after swapping if the viewable window before swapping is located in a primary screen;

(d5) obtaining a second coordinate by subtracting the window movement distance from the coordinate of the viewable window after swapping if the viewable window before swapping is not located in the primary screen; and

(d6) moving the viewable window according to the first coordinate or the second coordinate.

8. The method according to claim 7, wherein, the step (d1) further comprises:

identifying respective resolution of the first screen and the second screen.

9. The method according to claim 6, further comprising:

if the viewable window is a maximized window or a minimized window, then;

restoring the viewable window as a normal viewable viewable window;

moving the viewable window; and

restoring the viewable window back as the maximized window or the minimized window.
