Abstract

A method and apparatus for managing the display of multiple windows in a computer user interface in an efficient manner. Two separate window areas are allocated in a display area. A first area is an overlapped window area where windows may overlap each other. A second area is a tiled window area where windows may not overlap each other. User interface controls are provided to allow the user to designate a displayed window as tiled or overlapped and the designated window is moved from area to area, accordingly. Windows in either area may be resized and repositioned, although with some restrictions in the tiled area. The computer system automatically adjusts window and area sizes within predefined limits.

Claims

1. A computer program product that displays overlapped and tiled windows on a display screen, comprising:

computer code that displays a first window in an overlapped area on the display screen;

computer code that displays a second window in a tiled area on the display screen while the first window is displayed in the overlapped area on the display screen;

computer code that adds a third window to one of the overlapped and tiled areas on the display screen, the first and third windows being displayed overlapped if the third window is added to the overlapped area, and the second and third windows being displayed tiled if the third window is added to the tiled area; and

a computer readable medium that stores the computer codes.

2. The computer program product of claim 1, further comprising:

computer code that accepts user input to select a window in the overlapped area to move to the tiled area on the display screen; and

computer code that tiles the selected window in the tiled area.

3. The computer program product of claim 2, further comprising computer code that allows a user to drag the selected window from the tiled area to the tiled area on the display screen.

4. The computer program product of claim 2, further comprising computer code that displays a tile button in the selected window which causes the selected window to be moved to the tiled area when activated by the user input.

5. The computer program product of claim 2, further comprising computer code that allows a user to access a menu to move the selected window from the tiled area to the tiled area on the display screen.

6. The computer program product of claim 1, further comprising computer code that accepts user input to move a boundary between the overlapped and tiled areas on the display screen.

7. The computer program product of claim 6, further comprising computer code that enlarges windows in the tiled area when moving the boundary increases the size of the tiled area.

8. The computer program product of claim 7, further comprising computer code that enlarges windows closer to their natural dimensions.

9. The computer program product of claim 6, further comprising computer code that reduces open space between windows in the tiled area when moving the boundary decreases the size of the tiled area.

10. The computer program product of claim 6, further comprising computer code that shrinks windows in the tiled area when moving the boundary decreases the size of the tiled area.

11. The computer program product of claim 1, further comprising computer code that accepts user input to move a border of a selected window in the tiled area on the display screen.

12. The computer program product of claim 11, further comprising computer code that reduces open space between windows in the tiled area when moving the border increases the size of the selected window.

13. The computer program product of claim 11, further comprising computer code that shrinks windows in the tiled area when moving the border increases the size of the selected window.

14. The computer program product of claim 11, wherein the computer readable medium is selected from the group consisting of a disk, tape or memory.
