Abstract

Methods and apparatus can scroll a displayed hierarchical data structure. A hierarchical data structure can include a first parent node and a plurality of child nodes of the parent node, the plurality of subordinate nodes including a first child node and a second child node. The first parent node can be displayed in a first position of a display area. The first child node can be displayed in a second position of the display area, the second position being adjacent the first position. The second child node can be displayed in the display area. A first instruction to scroll at least the second child node in a direction toward the first position can be received, and the second child node can be displayed in the second position.

Claims

1. A method for scrolling a displayed hierarchical data structure including a first parent node and a plurality of child nodes of the parent node, the plurality of subordinate nodes including a first child node and a second child node, the method comprising:

displaying the first parent node in a first position of a display area,

dispaying the first child node in a second position of the display area, the second position being adjacent the first position;

displaying the second child node in the display area;

receiving a first instruction to scroll at least the second child node in a direction toward the first position; and

displaying the second child node in the second position.

2. The method of claim 1, further comprising:

receiving a second instruction to scroll at least the second child node in the direction toward the first position;

determining that the second child node is the only child node of the parent node displayed in the display area; and

scrolling the parent node and the second child node off of the display area.

3. The method of claim 1, further comprising:

displaying a second parent node in the display area;

receiving an instruction to scroll at least the second parent node in the direction toward the first position; and

displaying the second parent node in the first position.

4. The method of claim 1, further comprising:

displaying a second parent node;

displaying a hierarchical data level selector;

receiving an instruction to display the first parent node and second parent node without displaying the plurality of child nodes based at least in part upon a first activation of the hierarchical data level selector; and

displaying the second parent node in the second position.

5. The method of claim 4, further comprising:

receiving an instruction to display the first parent node and second parent node with a display of the plurality of subordinate nodes based at least in part upon a second activation of the hierarchical data level selector; and

displaying the first child node in the second position.

6. An apparatus to scroll a displayed hierarchical data structure including a first parent node and a plurality of child nodes of the parent node, the plurality of child nodes including a first child node and a second child node, the apparatus comprising:

a. a processor; and

b. a memory, coupled to said processor, storing a plurality of instructions adapted to be executed by said processor to

display the first parent node in a first position of a display area,

display the first child node in a second position of the display area, the second position being adjacent the first position,

display the second child node in the display area,

receive a first instruction to scroll at least the second child node in a direction toward the first position, and

display the second child node in the second position.

7. A computer-readable medium storing a plurality of instructions adapted to be executed by a processor to scroll a displayed hierarchical data structure including a first parent node and a plurality of child nodes of the parent node, the plurality of child nodes including a first child node and a second child node, the plurality of instructions comprising instructions to:

display the first parent node in a first position of a display area,

display the first child node in a second position of the display area, the second position being adjacent the first position;

display the second child node in the display area;

receive a first instruction to scroll at least the second child node in a direction toward the first position; and

display the second child node in the second position.
