Other worksheet areas.

Data entry area.

Immediately under the button bar is the data entry area. This is a small area, which contains a current cell indicator, a confirm and a cancel button, and an entry area for detailed editing of the cell contents. See Figure 1-3

Figure 1-3. The Data Entry area.

Current Cell Indicator.

On the far left of the Data Entry area is the current cell indicator area. If a single cell is selected, it will show the address for the cell. If a region is selected, it shows the size of the region in the format:

4Lx5C

Where L is the number of rows and C is the number of columns. In the example above, this would be a selection of 4 rows by 5 columns.

Figure 1-4. The Current Cell Indicator.

The Confirm Button

While entering data in the entry area, you can confirm the current cell contents by pressing the green return button .

The Cancel Button

If a user decides that the data entered into a cell is not what they want, the Cancel button will cancel the current data and return the cell to the state it was at before. The data being entered into the cell can be canceled by pressing the red X button .

The most common use of this is when overwriting the contents of a cell with new data. If the user decided to revert the change before confirming it, the cancel button is the answer.

The Cell area

Most of the work done on a spreadsheet is done to the main Cell area, the large grid like part of the worksheet. This is where all the formulas and data are entered, and is the center of activity for the spreadsheet.

The sheet is bordered by a column label and a row label. Columns are labeled alphabetically and are labeled horizontally across the top of the sheet. See Figure 1-5. Rows are labeled vertically along size the left side of the sheet and are sorted numerically. See Figure 1-6

Figure 1-5. The column labels at the top of the worksheet.

The Info Area

The section at the very bottom of the worksheet view is the info area. It contains information about the currently selected cells. This is also where the sheet indicator lives.

Figure 1-7. The info area.

Sheet indicator

To the left side is the sheet indicator. In workbooks where there are more than one sheet, this indicates how many sheets are there, and also allows the user to move to another sheet by clicking the proper tag. This is not implemented yet.

The running calculation area

In the bottom right hand corner, is an info area that shows some constantly calculated values. The default set is to show the Sum of all the currently selected cells.

There is a right click option that includes a few more options. This can include Sum, Min, Max, Average, Count.
