Abstract

Methods and apparatus, including computer program products, for navigating user interface elements of a computer program application. In one aspect, a method includes grouping user interface elements of an application into groups based on a hierarchical arrangement of the elements, detecting a navigation key press of a sibling or a parent navigation key, and if it is a sibling navigation key, shifting input focus to a next sibling group in the hierarchy, and if it is a parent navigation key, shifting input focus to a parent group in the hierarchy. In another aspect, a method for navigating editable cells of a table includes detecting a forward or a backward navigation key; if it is a forward navigation key, shifting input focus to a next editable cell of the table; and if it is a backward navigation key, shifting input focus to a previous editable cell of the table.

Claims

1. A method performed by a computer for navigating user interface elements, the method comprising:

receiving, by a processor associated with the computer, a display of a graphical user interface of a computer program application, the graphical user interface including user interface elements comprising a hierarchical arrangement of parent graphical user interface elements and sibling graphical user interface elements;

searching the display, by the processor, to identify the parent graphical user interface elements and the sibling graphical user interface elements;

collecting from the display, by the processor, text labels for the identified parent and sibling graphical user interface elements;

grouping, by the processor, the user interface elements alphabetically into parent groups and sibling groups based on alphanumeric characters contained in the collected text labels for the user interface elements;

detecting, by the processor, a user navigation input comprising a sibling navigation input and a user navigation input comprising a parent navigation input, the sibling navigation input comprising a sibling navigation key press plus a key press of a first alphanumeric character, the first alphanumeric character identifying a sibling group of user interface elements, and the parent navigation input comprising a parent navigation key press plus a key press of a second alphanumeric character, the second alphanumeric character identifying a parent group of user interface elements;

when the detected navigation input is the sibling navigation input;

identifying, by the processor, a sibling group of user interface elements having a text label alphabetically corresponding to the key press of the first alphanumeric character; and

shifting, by the processor, input focus to the identified sibling group; and

when the detected navigation input is the parent navigation input;

identifying, by the processor, a parent group of user interface having a text label alphabetically corresponding to the key press of the second alphanumeric character; and

shifting, by the processor, input focus to the identified parent group.

2. The method of claim 1, further comprising:

creating, by the processor, one or more hierarchical tab chains containing all user interface elements currently displayed by the application, the user interface elements in the one or more hierarchical tab chains being ordered alphabetically according to their associated text labels,

wherein a node in a tab chain hierarchy is a container comprising one or more user interface elements and the container comprises a tab chain that contains all the user interface elements in the container.

3. The method of claim 2, further comprising:

creating, by the processor, a new view container displaying a hierarchical tab chain that contains all the user interface elements for a new view of user interface elements, the user interface elements in the new view container being displayed in alphabetic order based on their associated text labels;

wherein the hierarchical tab chain for the new view is added to an existing hierarchical tab chain by adding a new node for the new view container in the existing hierarchical tab chain.

4. A computer-readable storage medium storing a computer program that, when executed by a computer, causes the computer to:

receive a display of a graphical user interface of a computer program application, the graphical user interface including graphical user interface elements comprising a hierarchical arrangement of parent graphical user interface elements and sibling graphical user interface elements;

search the display to identify the parent graphical user interface elements and the sibling graphical user interface elements;

collect from the display text labels for the identified parent and sibling graphical user interface elements;

group the user interface elements of a user interface alphabetically into parent groups and sibling groups based on alphanumeric characters contained in the collected text labels for the user interface elements;

detect a user navigation input comprising a sibling navigation input and a user navigation input comprising a parent navigation input, the sibling navigation input comprising a sibling navigation key press plus a key press of a first alphanumeric character, the first alphanumeric character identifying a sibling group of user interface elements, and the parent navigation input comprising a parent navigation key press plus a key press of a second alphanumeric character, the second alphanumeric character identifying a parent group of user interface elements;

when the detected navigation input is the sibling navigation input;

identifying a sibling group of user interface elements having a text label alphabetically corresponding to the key press of the first alphanumeric character; and

shifting input focus to the identified sibling group; and

when the detected navigation input is the parent navigation input;

identifying a parent group of user interface having a text label alphabetically corresponding to the key press of the second alphanumeric character; and

shifting input focus to the identified parent group.

5. The computer-readable storage medium of claim 4, the executed program further causing the computer to:

create one or more hierarchical tab chains containing all user interface elements currently displayed by the application, the user interface elements in the one or more hierarchical tab chains being ordered alphabetically according to their associated text labels,

wherein a node in a tab chain hierarchy is a container comprising one or more user interface elements and the container comprises a tab chain that contains all the user interface elements in the container.

6. The computer-readable storage medium of claim 5, the executed program further causing the computer to:

create a new view container displaying a hierarchical tab chain that contains all the user interface elements for the new view, the user interface elements in the new view container being displayed in alphabetic order according to their associated text labels;

wherein the hierarchical tab chain for the new view is added to an existing tab chain by adding a new node for the new view container in the existing hierarchical tab chain.

7. A system comprising:

means for receiving a display of a graphical user interface of a computer program application, the graphical user interface including user interface elements comprising a hierarchical arrangement of parent user interface elements and sibling user interface elements;

means for searching the display to identify the parent user interface elements and the sibling user interface elements;

means for collecting from the display text labels for the identified parent and sibling user interface elements;

means for grouping the user interface elements alphabetically into parent groups and sibling groups based on alphanumeric characters contained in the collected text labels for the user interface elements;

means for detecting a user navigation input comprising a sibling navigation input and a user navigation input comprising a parent navigation input, the sibling navigation input comprising a sibling navigation key press plus a key press of a first alphanumeric character, the first alphanumeric character identifying a sibling group of user interface elements, and the parent navigation input comprising a parent navigation key press plus a key press of a second alphanumeric character, the second alphanumeric character identifying a parent group of user interface elements;

means for, when the detected navigation input is the sibling navigation input;

identifying a sibling group of user interface elements having a text label alphabetically corresponding to the key press of the first alphanumeric character; and

shifting input focus to the identified sibling group; and

means for, when if the detected navigation input is the parent navigation input;

identifying a parent group of user interface elements having a text label alphabetically corresponding to the key press of the second alphanumeric character; and

shifting input focus to the identified parent group.

8. The system of claim 7, further comprising:

means for creating one or more hierarchical tab chains containing all user interface elements currently displayed by the application, the user interface elements in the one or more hierarchical tab chains being ordered alphabetically according to their associated text labels,

wherein a node in a tab chain hierarchy is a container comprising one or more user interface elements and the container comprises a tab chain that contains all the user interface elements in the container.

9. The system of claim 8, further comprising:

creating a new view container displaying a hierarchical tab chain containing all the user interface elements for the new view, the user interface elements in the new view container being displayed in alphabetic order based on their associated text labels;
