1. Field of Invention
The present invention generally relates to user interface controls. Specifically, the present invention relates to the control of a set of grid lines displayed in a user interface.
2. Related Art
Many of today's software applications utilize visible grid lines to enhance a user's experience. For example, software development tools exist with the capability to allow software developers to define the content of displayable pages for character based 3270 or 5250 type terminal displays, otherwise known as green screens. Each displayable page includes of a set of characters arranged in a two-dimensional column/row grid configuration, the most common configuration being 80 columns wide by 24 rows high. A development tool may visually show the tool user the location of each cell in a grid of cells by displaying grid lines between each cell. Image editing tools also exist with the capability to display horizontal and vertical grid lines to aid in image alignment tasks.
Unfortunately, existing tools only provide a single grid style, a single grid intensity and a single user interface control which allows the tool user to control the visibility of grid lines. In view of the foregoing, there exists a need for a solution that solves at least one of the deficiencies of the related art.
In general, the present invention provides a solution for controlling the appearance gridlines. Specifically, the present invention provides a user interface control such as a slider or the like that allows a user to control both the style and intensity of displayed set of grid lines.

I. General Description
II. Computerized Implementation
As indicated above, the present invention provides a solution for controlling gridlines. Specifically, the present invention provides a user interface control such as a slider or the like that allows a user to control both the style and intensity of a displayed set of grid lines. In a typical embodiment, the user interface control has a plurality of settings that each are associated with a particular intensity value and style value. In response to a manipulation by a user, the style and intensity of the set of grid lines will be simultaneously controlled/changed accordingly. The values are disposed within/among a plurality of ranges, one or more of which can overlap. Manipulation of the user interface control within any of the overlapping portion(s) can result in the set of grid lines being displayed with multiple styles and intensities.
Among other things, this invention extends current capabilities by supporting multiple, simultaneously drawn grid line styles and intensities, and provides a method for a single user interface widget/control to control how grid lines are drawn. For example, this invention extends the control of basic grid lines used in today's tools in the following ways:
(1) Grid line styles
(2) Multiple cell indication
(3) Grid user interface control
(4) Configuration
Under the present invention, a grid intensity range is defined as a set of numeric values that has a minimum (e.g. zero) and a predefined maximum, such as 100. A grid intensity user interface control is defined as a user interface control that allows a person to choose a specific value within the grid intensity range (a grid intensity value). Examples of user interface controls that can be used are sliders, scroll bars and spin buttons. A grid style is defined as the way a grid line is drawn, such as dotted, dashed or solid. However, grid style can refer to any type of formatting such as color, line thickness, etc. In addition, under the present invention, a grid line can be drawn at various line intensities. The intensity of a drawn grid line, its line intensity, can have a range of between zero and a predefined maximum, such as 255. The line intensity varies as a function of the grid intensity.
To this extent, a grid intensity region can be defined as having the following: (1) a grid style; (2) a range within the grid intensity range denoted by minimum and maximum grid intensity values; and/or (3) an intensity mapping function which maps from a grid intensity value to a line intensity value (the intensity at which a line is drawn). Either a linear or non-linear mapping function may be used. For example, a grid intensity region can have one or more of the following properties: (1) a dotted line style; (2) minimum and maximum grid intensity values which are the same as grid intensity range minimum and maximum values, such as from zero to 100 inclusive; and/or (3) a linear intensity mapping function which increases the line intensity value linearly as the grid intensity value increases.

As indicated above, under the present invention, multiple grid intensity regions can be used together. The illustrative graph 12 shown in
These features are further shown in the following table:
In addition, the present invention allows columns and/or rows to be highlighted (e.g., every nth column or row may be highlighted). For example, in order to indicate every tenth column in a grid, the line drawn after every tenth column is drawn highlighted. Along these lines, one or more of the following properties can additionally be defined for a grid intensity region: (1) a column highlight period—specifies the number of columns between each highlighted column; (2) a row highlight period—specifies the number of rows between each highlighted row; and/or (3) a highlight intensity factor—a positive real number, when multiplied by the intensity determined by the intensity mapping function for a value in the grid intensity region, results in a highlighted line intensity value.
The table below shows characteristic values for three grid intensity regions with highlight intensity factors:
In general, the present invention implements the following method for drawing such grid lines. Specifically, a user specifies a grid intensity, for instance by using a user interface control such as a slider, or scroll bar. Depending on the value of the grid intensity, lines are drawn using the set of either predefined, or user defined grid intensity regions. The following method can be employed:
(1) For all grid lines to be drawn, whether they are horizontal or vertical,

Further, computer system 24 is shown in communication with external I/O devices/resources 34 and storage system 36. In general, processing unit 26 executes computer program code, such as application 38 and grid control program 40, which are stored in memory 28 and/or storage system 36. While executing computer program code, processing unit 26 can read and/or write data to/from memory 28, storage system 36, and/or I/O interfaces 32. Bus 30 provides a communication link between each of the components in computer system 24. External devices 34 can comprise any devices (e.g., keyboard, pointing device, display, etc.) that enable a user to interact with computer system 24 and/or any devices (e.g., network card, modem, etc.) that enable computer system 24 to communicate with one or more other computing devices.
Computer infrastructure 22 is only illustrative of various types of computer infrastructures for implementing the invention. For example, in one embodiment, computer infrastructure 22 comprises two or more computing devices (e.g., a server cluster) that communicate over a network to perform the process(es) of the invention. Moreover, computer system 24 is only representative of various possible computer systems that can include numerous combinations of hardware. To this extent, in other embodiments, computer system 24 can comprise any specific purpose computing article of manufacture comprising hardware and/or computer program code for performing specific functions, any computing article of manufacture that comprises a combination of specific purpose and general purpose hardware/software, or the like. In each case, the program code and hardware can be created using standard programming and engineering techniques, respectively. Moreover, processing unit 26 may comprise a single processing unit, or be distributed across one or more processing units in one or more locations, e.g., on a client and server. Similarly, memory 28 and/or storage system 36 can comprise any combination of various types of data storage and/or transmission media that reside at one or more physical locations. Further, I/O interfaces 32 can comprise any system for exchanging information with one or more external device 36. Still further, it is understood that one or more additional components (e.g., system software, math co-processing unit, etc.) not shown in
Storage system 36 can be any type of system (e.g., a database) capable of providing storage for information under the present invention. To this extent, storage system 36 could include one or more storage devices, such as a magnetic disk drive or an optical disk drive. In another embodiment, storage system 36 includes data distributed across, for example, a local area network (LAN), wide area network (WAN) or a storage area network (SAN) (not shown). In addition, although not shown, additional components, such as cache memory, communication systems, system software, etc., may be incorporated into computer system 24. It should be understood computer system could be any combination of hardware and/or software. It is shown as such to illustrate the functions as described herein.
Shown in memory 28 of computer system 24 are application 38 and grid control program 40, the latter of which facilitates the functions as described herein. Application 38 can be any software program that is capable of displaying a user interface with grid lines. Examples include software development programs, spreadsheet programs, etc. As depicted, grid control program 40 includes user interface control module 42, and grid control module 44. It should be understood that this configuration of functionality is intended to be illustrative only, and that identical or similar functionality could be provided with a different configuration of systems.
In any event, when application 38 renders a user interface with a set (e.g., at least one) of gridlines, user interface control module 42 will render and display a user interface control that allows for user-controlled formatting of the set of gridlines. In a typical embodiment, the user interface control is a single control that allows both the style (e.g., solid or dashed) and intensity (e.g., brightness) of set of gridlines to be user controlled simultaneously. It should be understood, however, that the user interface control could allow other formatting features to be controlled such as highlighting, color, etc.

In a typical embodiment, user interface control 50 includes a plurality of positions, each of which is mapped to a particular style value and intensity value (as well as a value of any other formatting options desired). Based on the position of slider 52, a particular style value and intensity value will be “selected”. Along these lines, the values and positions can be disposed/arranged into a plurality of regions, one or more of which can optionally overlap. For example, region 1 could exist from 0-40, region 2 could exist from 30-60, and region could exist from 50-100. To this extent, if a user brings slider 52 to a rest within two overlapping regions, multiple styles can be caused. For example, if the user brought slider 52 to resting position “A” within two overlapping regions, the set of gridlines could be displayed with intensity “W” and “X” corresponding to the intensity values at resting position “A”, as well as with styles “Y and Z” (e.g., dashed and solid lines) corresponding to the style values at resting position “A.”
